113-454: It was founded on July 21, 1957, by Miguel Ángel Maldonado , his brother Jorge Efrain, and his wife, María García de Maldonado , with the latter running the company after her husband's death in 1972, at the age of 46. This Guatemala -related article is a stub . You can help Misplaced Pages by expanding it . Guatemala Guatemala , officially the Republic of Guatemala ,

226-628: A UNESCO World Heritage Site . This city was destroyed by several earthquakes in 1773–1774. The King of Spain authorized moving the capital to its current location in the Ermita Valley, which is named after a Catholic church dedicated to the Virgen del Carmen . This new capital was founded on 2 January 1776. On 15 September 1821, Gabino Gainza Fernandez de Medrano and the Captaincy General of Guatemala , an administrative region of

339-609: A staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice . Much maize is used for animal feed , whether as grain or as the whole plant, which can either be baled or made into the more palatable silage . Sugar-rich varieties called sweet corn are grown for human consumption, while field corn varieties are used for animal feed, for uses such as cornmeal or masa , corn starch , corn syrup , pressing into corn oil , alcoholic beverages like bourbon whiskey , and as chemical feedstocks including ethanol and other biofuels . Maize

452-402: A bomb exploded near his carriage. It has been suggested that the extreme despotic characteristics of Estrada did not emerge until after an attempt on his life in 1907. Guatemala City was badly damaged in the 1917 Guatemala earthquake . Estrada Cabrera continued in power until forced to resign after new revolts in 1920. By that time his power had declined drastically and he was reliant upon

565-814: A conventional breeding program to provide optimized strains. The program began in the 1980s. Hybrid seeds are distributed in Africa by its Drought Tolerant Maize for Africa project. Tropical landraces remain an important and underused source of resistance alleles – both those for disease and for herbivores . Such alleles can then be introgressed into productive varieties. Rare alleles for this purpose were discovered by Dao and Sood, both in 2014. In 2018, Zerka Rashid of CIMMYT used its association mapping panel, developed for tropical drought tolerance traits. to find new genomic regions providing sorghum downy mildew resistance , and to further characterize known differentially methylated regions . Genetically modified maize

678-403: A corn head (with points and snap rolls instead of a reel) does not cut the stalk; it simply pulls the stalk down. The stalk continues downward and is crumpled into a mangled pile on the ground, where it usually is left to become organic matter for the soil . The ear of maize is too large to pass between slots in a plate as the snap rolls pull the stalk away, leaving only the ear and husk to enter

791-597: A criollo caudillo like Morazán, who was able to crush the peasant rebellion. Morazán used the proceeds to support Los Altos and then replaced Valenzuela with Mariano Rivera Paz , a member of the Aycinena clan, although he did not return to that clan any property confiscated in 1829. In revenge, Juan José de Aycinena y Piñol voted to dissolve the Central American Federation in San Salvador

904-605: A dangerous jungle infested with jaguars to meet his former friend. Zavala not only did not capture him, he agreed to serve under his orders, thus sending a strong message to both liberal and conservatives in Guatemala City that they would have to negotiate with Carrera or battle on two fronts – Quetzaltenango and Jalapa. Carrera went back to the Quetzaltenango area, while Zavala remained in Suchitepéquez as

1017-737: A detachment in Jutiapa and got a small amount of booty which he gave to the volunteers who accompanied him. He then prepared to attack Petapa near Guatemala City, where he was victorious, although with heavy casualties. In September of that year, Carrera attempted an assault on the capital of Guatemala, but the liberal general Carlos Salazar Castro defeated him in the fields of Villa Nueva and Carrera had to retreat. After unsuccessfully trying to take Quetzaltenango , Carrera found himself both surrounded and wounded. He had to capitulate to Mexican General Agustín Guzmán , who had been in Quetzaltenango since Vicente Filísola 's arrival in 1823. Morazán had

1130-509: A friend: "Now he is the king of the Indians, indeed!" Guzmán then left for Jalapa, where he struck a deal with the rebels, while Luis Batres Juarros convinced President Paredes to deal with Carrera. Back in Guatemala City within a few months, Carrera was commander-in-chief, backed by military and political support of the Indian communities from the densely populated western highlands. During

1243-450: A huge column of Quetzaltenango and Totonicapán indigenous people came down from the mountains to vote for him. Reyna was elected president. José María Reina Barrios was president between 1892 and 1898. During Barrios's first term in office, the power of the landowners over the rural peasantry increased. He oversaw the rebuilding of parts of Guatemala City on a grander scale, with wide, Parisian-style avenues. He oversaw Guatemala hosting

1356-408: A large cob. Yellow maizes derive their color from carotenoids ; red maizes are colored by anthocyanins and phlobaphenes ; and orange and green varieties may contain combinations of these pigments. Maize has short-day photoperiodism , meaning that it requires nights of a certain length to flower. Flowering further requires enough warm days above 10 °C (50 °F). The control of flowering

1469-482: A little later, forcing Morazán to return to El Salvador to fight for his federal mandate. Along the way, Morazán increased repression in eastern Guatemala, as punishment for helping Carrera. Knowing that Morazán had gone to El Salvador, Carrera tried to take Salamá with the small force that remained, but was defeated, and lost his brother Laureano in combat. With just a few men left, he managed to escape, badly wounded, to Sanarate . After recovering somewhat, he attacked

1582-499: A measure of protection against a wide range of pests. Because of its shallow roots, maize is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to being uprooted by severe winds. Maize is diploid with 20 chromosomes . 83% of allelic variation within the genome derives from its teosinte ancestors, primarily due to the freedom of Zea species to outcross . Barbara McClintock used maize to validate her transposon theory of "jumping genes", for which she won

1695-469: A member of the Liberal Party , he sought to encourage development of the nation's infrastructure of highways , railroads , and sea ports for the sake of expanding the export economy. By the time Estrada Cabrera assumed the presidency there had been repeated efforts to construct a railroad from the major port of Puerto Barrios to the capital, Guatemala City. Owing to lack of funding exacerbated by

1808-533: A native revolt, much like that of 1840; their only request from Carrera was to keep the natives under control. The altenses did not comply, and led by Guzmán and his forces, they started chasing Carrera; the caudillo hid, helped by his native allies and remained under their protection when the forces of Miguel Garcia Granados arrived from Guatemala City looking for him. On learning that officer José Víctor Zavala had been appointed as Corregidor in Suchitepéquez, Carrera and his hundred jacalteco bodyguards crossed

1921-642: A peasant. With Salazar gone, Carrera reinstated Rivera Paz as head of state. Between 1838 and 1840 a secessionist movement in the city of Quetzaltenango founded the breakaway state of Los Altos and sought independence from Guatemala. The most important members of the Liberal Party of Guatemala and liberal enemies of the conservative régime moved to Los Altos, leaving their exile in El Salvador. The liberals in Los Altos began severely criticizing

2034-638: A place but a condition, a savage rather than a civilized grain". International groups such as the Centre for Agriculture and Bioscience International consider maize the preferred common name. The word maize is used by the UN's Food and Agriculture Organization , and in the names of the International Maize and Wheat Improvement Center of Mexico, the Indian Institute of Maize Research,

2147-601: A plant that uses C 4 carbon fixation , maize is a considerably more water-efficient crop than plants that use C 3 carbon fixation such as alfalfa and soybeans . Maize is most sensitive to drought at the time of silk emergence, when the flowers are ready for pollination. In the United States, a good harvest was traditionally predicted if the maize was "knee-high by the Fourth of July ", although modern hybrids generally exceed this growth rate. Maize used for silage

2260-538: A tactical maneuver. Carrera received a visit from a cabinet member of Paredes and told him that he had control of the native population and that he assured Paredes that he would keep them appeased. When the emissary returned to Guatemala City, he told the president everything Carrera said, and added that the native forces were formidable. Guzmán went to Antigua to meet with another group of Paredes emissaries; they agreed that Los Altos would rejoin Guatemala, and that

2373-640: Is a country in Central America . It is bordered to the north and west by Mexico , to the northeast by Belize , to the east by Honduras , and to the southeast by El Salvador . It is hydrologically bordered to the south by the Pacific Ocean and to the northeast by the Gulf of Honduras . The territory of modern Guatemala hosted the core of the Maya civilization , which extended across Mesoamerica ; in

2486-477: Is a problem in Asia. Some fungal diseases of maize produce potentially dangerous mycotoxins such as aflatoxin . In the United States, major diseases include tar spot , bacterial leaf streak , gray leaf spot , northern corn leaf blight, and Goss's wilt ; in 2022, the most damaging disease was tar spot, which caused losses of 116.8 million bushels . Maize sustains a billion dollars' worth of losses annually in

2599-572: Is characterized by urbanisation, the emergence of independent city-states, and contact with other Mesoamerican cultures. This lasted until approximately 900 AD, when the Classic Maya civilization collapsed . The Maya abandoned many of the cities of the central lowlands or were killed by a drought-induced famine . The cause of the collapse is debated, but the drought theory is gaining currency, supported by evidence such as lakebeds, ancient pollen, and others. A series of prolonged droughts in what

2712-408: Is composed of transposons , contains 32,540 genes. Much of it has been duplicated and reshuffled by helitrons , a group of transposable elements within maize's DNA. Maize breeding in prehistory resulted in large plants producing large ears. Modern breeding began with individuals who selected highly productive varieties in their fields and then sold seed to other farmers. James L. Reid was one of

2825-537: Is cultivated throughout the world; a greater weight of maize is produced each year than any other grain. In 2020, world production was 1.1 billion tonnes. It is afflicted by many pests and diseases ; two major insect pests, European corn borer and corn rootworms , have each caused annual losses of a billion dollars in the US. Modern plant breeding has greatly increased output and qualities such as nutrition, drought tolerance, and tolerance of pests and diseases. Much maize

2938-414: Is harvested while the plant is green and the fruit immature. Sweet corn is harvested in the "milk stage", after pollination but before starch has formed, between late summer and early to mid-autumn. Field maize is left in the field until very late in the autumn to thoroughly dry the grain, and may, in fact, sometimes not be harvested until winter or even early spring. The importance of sufficient soil moisture

3051-533: Is now genetically modified . As a food, maize is used to make a wide variety of dishes including Mexican tortillas and tamales , Italian polenta , and American hominy grits . Maize protein is low in some essential amino acids , and the niacin it contains only becomes available if freed by alkali treatment . In Mesoamerica, maize is deified as a maize god and depicted in sculptures. Maize requires human intervention for it to propagate. The kernels of its naturally-propagating teosinte ancestor fall off

3164-735: Is otherwise a seasonal desert is thought to have decimated the Maya, who relied on regular rainfall to support their dense population. The Post-Classic period is represented by regional kingdoms, such as the Itza , Kowoj , Yalain and Kejache in Petén, and the Mam , Ki'che' , Kackchiquel , Chajoma , Tz'utujil , Poqomchi' , Q'eqchi' and Ch'orti' peoples in the highlands. Their cities preserved many aspects of Maya culture. The Maya civilization shares many features with other Mesoamerican civilizations due to

3277-468: Is set genetically; the physiological mechanism involves the phytochrome system. Tropical cultivars can be problematic if grown in higher latitudes, as the longer days can make the plants grow tall instead of setting seed before winter comes. On the other hand, growing tall rapidly could be convenient for producing biofuel. Immature maize shoots accumulate a powerful antibiotic substance, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one ( DIMBOA ), which provides

3390-560: Is shown in many parts of Africa, where periodic drought regularly causes maize crop failure and consequent famine . Although it is grown mainly in wet, hot climates, it can thrive in cold, hot, dry or wet conditions, meaning that it is an extremely versatile crop. Maize was planted by the Native Americans in small hills of soil, in the polyculture system called the Three Sisters . Maize provided support for beans ;

3503-557: Is the domesticated variant of the four species of teosintes , which are its crop wild relatives . The teosinte origin theory was proposed by the Russian botanist Nikolai Ivanovich Vavilov in 1931, and the American Nobel Prize -winner George Beadle in 1932. The two plants have dissimilar appearance, maize having a single tall stalk with multiple leaves and teosinte being a short, bushy plant. The difference between

3616-405: Is the leaf most closely associated with a particular developing ear. This leaf and those above it contribute over three quarters of the carbohydrate ( starch ) that fills the grain. The grains are usually yellow or white in modern varieties; other varieties have orange, red, brown, blue , purple , or black grains. They are arranged in 8 to 32 rows around the cob; there can be up to 1200 grains on

3729-709: Is the most populous city in Central America. The name "Guatemala" comes from the Nahuatl word Cuauhtēmallān , or "place of many trees", a derivative of the K'iche' Mayan word for "many trees" or, perhaps more specifically, for the Cuate/Cuatli tree Eysenhardtia . This name was originally used by the Mexica to refer to the Kaqchikel city of Iximche , but was extended to refer to the whole country during

3842-612: The Balsas River valley in Mexico's southwestern highlands, as the crop wild relative genetically most similar to modern maize. The middle part of the short Balsas River valley is the likely location of early domestication. Stone milling tools with maize residue have been found in an 8,700 year old layer of deposits in a cave not far from Iguala, Guerrero . Doebley and colleagues showed in 2002 that maize had been domesticated only once, about 9,000 years ago, and then spread throughout

3955-531: The Maya area . Many outside influences are found in Maya art and architecture, which are thought to have resulted from trade and cultural exchange rather than direct external conquest. After they arrived in the New World , the Spanish started several expeditions to Guatemala, beginning in 1519. Before long, Spanish contact resulted in an epidemic that devastated native populations. Hernán Cortés , who had led

4068-802: The Quiché region in the Highlands, and Sipacate and Escuintla on the central Pacific coast. Archaeologists divide the pre-Columbian history of Mesoamerica into the Preclassic period (3000 BC to 250 AD), the Classic period (250 to 900 AD), and the Postclassic period (900 to 1500 AD). Until recently, the Preclassic was regarded by researchers as a formative period, in which the peoples typically lived in huts in small villages of farmers, with few permanent buildings. This notion has been challenged since

4181-540: The Spanish conquest of Mexico , granted a permit to Captains Gonzalo de Alvarado and his brother, Pedro de Alvarado , to conquer this land. Alvarado at first allied himself with the Kaqchikel nation to fight against their traditional rivals the K'iche' (Quiché) nation . Alvarado later turned against the Kaqchikel, and eventually brought the entire region under Spanish domination. During the colonial period, Guatemala

4294-483: The Three Sisters polyculture . The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen , and female inflorescences called ears . The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange , it has become

4407-542: The United Provinces of Central America . In 1840, Belgium began to act as an external source of support for Carrera's independence movement, in an effort to exert influence in Central America. The Compagnie belge de colonisation (Belgian Colonization Company), commissioned by Belgian King Leopold I , became the administrator of Santo Tomas de Castilla replacing the failed British Eastern Coast of Central America Commercial and Agricultural Company . Even though

4520-566: The United States . In 1944, authoritarian leader Jorge Ubico was overthrown by a pro-democratic military coup, initiating a decade-long revolution that led to social and economic reforms. In 1954, a US-backed military coup ended the revolution and installed a dictatorship. From 1960 to 1996, Guatemala endured a bloody civil war fought between the US-backed government and leftist rebels, including genocidal massacres of

4633-491: The 16th century, most of this was conquered by the Spanish and claimed as part of the viceroyalty of New Spain . Guatemala attained independence from Spain and Mexico in 1821. From 1823 to 1841, it was part of the Federal Republic of Central America . For the latter half of the 19th century, Guatemala suffered instability and civil strife. From the early 20th century, it was ruled by a series of dictators backed by

On 11 September 1541, the new capital was flooded when the lagoon in the crater of the Agua Volcano collapsed due to heavy rains and earthquakes; the capital was then moved 6 km (4 mi) to Antigua in the Panchoy Valley, now

4972-662: The Americas. Maize pollen dated to 7,300 years ago from San Andres, Tabasco has been found on the Caribbean coast. A primitive corn was being grown in southern Mexico, Central America, and northern South America 7,000 years ago. Archaeological remains of early maize ears, found at Guila Naquitz Cave in the Oaxaca Valley , are roughly 6,250 years old; the oldest ears from caves near Tehuacan , Puebla, are 5,450 years old. Around 4,500 years ago, maize began to spread to

5085-584: The Army Marshall rank, even though that rank did not exist and it does not exist in the Guatemalan military. The Marshall called himself President of the Republic, but in reality he was the foreman of oppressed and savaged people, cowardly enough that they had not dared to tell the dictator to leave threatening him with a revolution. The State and Church were a single unit, and the conservative régime

5198-466: The Atlantic side. In 1906 Estrada faced serious revolts against his rule; the rebels were supported by the governments of some of the other Central American nations, but Estrada succeeded in putting them down. Elections were held by the people against the will of Estrada Cabrera and thus he had the president-elect murdered in retaliation. In 1907 Estrada narrowly survived an assassination attempt when

5311-479: The B-vitamin niacin , the lack of which caused pellagra . Once alkali processing and dietary variety were understood and applied, pellagra disappeared in the developed world. The development of high- lysine maize and the promotion of a more balanced diet have contributed to its demise. Pellagra still exists in food-poor areas and refugee camps where people survive on donated maize. The name maize derives from

5424-495: The Conservative government of Rivera Paz. Los Altos was the region with the main production and economic activity of the former state of Guatemala. Without Los Altos, conservatives lost many of the resources that had given Guatemala hegemony in Central America. The government of Guatemala tried to reach a peaceful solution, but two years of bloody conflict followed. On 17 April 1839, Guatemala declared itself independent from

5537-553: The Federation of Central America from 9 September 1921 until 14 January 1922. Maize Maize / m eɪ z / ( Zea mays ), also known as corn in North American English , is a tall stout grass that produces cereal grain . It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte . Native Americans planted it alongside beans and squashes in

5650-417: The Guatemalan government in several different ways. José Francisco Barrundia established a liberal newspaper for that specific purpose. Vasconcelos supported a rebel faction named "La Montaña" in eastern Guatemala, providing and distributing money and weapons. By late 1850, Vasconcelos was getting impatient at the slow progress of the war with Guatemala and decided to plan an open attack. Under that circumstance,

5763-680: The Guatemalans suffered a severe defeat , which was followed by a truce. Honduras joined with El Salvador, and Nicaragua and Costa Rica with Guatemala. The contest was finally settled in favor of Carrera, who besieged and occupied San Salvador , and dominated Honduras and Nicaragua. He continued to act in concert with the Clerical Party, and tried to maintain friendly relations with European governments. Before he died, Carrera nominated his friend and loyal soldier, Army Marshall Vicente Cerna y Cerna , as his successor. Vicente Cerna y Cerna

5876-709: The Maize Association of Australia, the National Maize Association of Nigeria, the National Maize Association of Ghana, the Maize Trust of South Africa, and the Zimbabwe Seed Maize Association. Maize is a tall annual grass with a single stem, ranging in height from 1.2 m (4 ft) to 4 m (13 ft). The long narrow leaves arise from the nodes or joints, alternately on opposite sides on

5989-406: The Maya population perpetrated by the Guatemalan military. The United Nations negotiated a peace accord, resulting in economic growth and successive democratic elections. Guatemala's abundance of biologically significant and unique ecosystems includes many endemic species and contributes to Mesoamerica's designation as a biodiversity hotspot . Although rich in export goods, around a quarter of

6102-581: The Salvadorean head of state started a campaign against the conservative Guatemalan regime, inviting Honduras and Nicaragua to participate in the alliance; only the Honduran government led by Juan Lindo accepted. In 1851 Guatemala defeated an Allied army from Honduras and El Salvador at the Battle of La Arada . In 1854 Carrera was declared "supreme and perpetual leader of the nation" for life, with

6215-722: The Spanish Empire consisting of Chiapas , Guatemala, El Salvador , Nicaragua, Costa Rica, and Honduras, officially proclaimed its independence from Spain at a public meeting in Guatemala City. Independence from Spain was gained, and the Captaincy General of Guatemala joined the First Mexican Empire under Agustín de Iturbide . Under the First Empire, Mexico reached its greatest territorial extent, stretching from northern California to

6328-445: The Spanish colonial period. The first evidence of human habitation in Guatemala dates to 12,000 BC. Archaeological evidence, such as obsidian arrowheads found in various parts of the country, suggests a human presence as early as 18,000 BC. There is archaeological proof that early Guatemalan settlers were hunter-gatherers . Maize cultivation had been developed by the people by 3500 BC. Sites dating to 6500 BC have been found in

6441-531: The Spanish form maíz of the Taíno mahis . The Swedish botanist Carl Linnaeus used the common name maize as the species epithet in Zea mays . The name maize is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike corn , which has a complex variety of meanings that vary by context and geographic region. Most countries primarily use

6554-562: The US National Science Foundation , Department of Agriculture, and the Department of Energy formed a consortium to sequence the maize genome . The resulting DNA sequence data was deposited immediately into GenBank , a public repository for genome-sequence data. Sequencing of the maize genome was completed in 2008. In 2009, the consortium published results of its sequencing effort. The genome, 85% of which

Another serious pest is the fall armyworm ( Spodoptera frugiperda ). The maize weevil ( Sitophilus zeamais ) is a serious pest of stored grain. The Northern armyworm, Oriental armyworm or Rice ear-cutting caterpillar ( Mythimna separata )

6780-418: The beans provided nitrogen derived from nitrogen-fixing rhizobia bacteria which live on the roots of beans and other legumes ; and squashes provided ground cover to stop weeds and inhibit evaporation by providing shade over the soil. Sweet corn, harvested earlier than maize grown for grain, grows to maturity in a period of from 60 to 100 days according to variety. An extended sweet corn harvest, picked at

6893-613: The body of Christ. Maize spread to the rest of the world because of its ability to grow in diverse climates. It was cultivated in Spain just a few decades after Columbus's voyages and then spread to Italy, West Africa and elsewhere. By the 17th century, it was a common peasant food in Southern Europe. By the 18th century, it was the chief food of the southern French and Italian peasantry, especially as polenta in Italy. When maize

They declared on 26 August 1848 that Los Altos was an independent state once again. The new state had the support of Doroteo Vasconcelos ' régime in El Salvador and the rebel guerrilla army of Vicente and Serapio Cruz, who were sworn enemies of Carrera. The interim government

7119-522: The cob on their own, while those of domesticated maize do not. All maize arose from a single domestication in southern Mexico about 9,000 years ago. The oldest surviving maize types are those of the Mexican highlands. Maize spread from this region to the lowlands and over the Americas along two major paths. The centre of domestication was most likely the Balsas River valley of south-central Mexico. Maize reached highland Ecuador at least 8000 years ago. It reached lower Central America by 7600 years ago, and

7232-406: The collapse of the internal coffee trade, the railway fell 100 kilometres (60 mi) short of its goal. Estrada Cabrera decided, without consulting the legislature or judiciary, that striking a deal with the UFCO was the only way to finish the railway. Cabrera signed a contract with UFCO's Minor Cooper Keith in 1904 that gave the company tax exemptions, land grants, and control of all railroads on

7345-399: The colony eventually crumbled, Belgium continued to support Carrera in the mid-19th century, although Britain continued to be the main business and political partner to Carrera. Rafael Carrera was elected Guatemalan Governor in 1844. On 21 March 1847, Guatemala declared itself an independent republic and Carrera became its first president. During the first term as president, Carrera brought

7458-495: The country back from extreme conservatism to a traditional moderation; in 1848, the liberals were able to drive him from office, after the country had been in turmoil for several months. Carrera resigned of his own free will and left for México. The new liberal regime allied itself with the Aycinena family and swiftly passed a law ordering Carrera's execution if he returned to Guatemalan soil. The liberal criollos from Quetzaltenango were led by general Agustín Guzmán who occupied

7571-544: The country to war in an unsuccessful attempt to attain it, losing his life on the battlefield in 1885 against forces in El Salvador. Manuel Barillas was president from 16 March 1886 to 15 March 1892. Manuel Barillas was unique among liberal presidents of Guatemala between 1871 and 1944: he handed over power to his successor peacefully. When election time approached, he sent for the three Liberal candidates to ask them what their government plan would be. Happy with what he heard from general Reyna Barrios , Barillas made sure that

7684-425: The earliest and most successful, developing Reid's Yellow Dent in the 1860s. These early efforts were based on mass selection (a row of plants is grown from seeds of one parent), and the choosing of plants after pollination (which means that only the female parents are known). Later breeding efforts included ear to row selection (C. G. Hopkins c. 1896), hybrids made from selected inbred lines (G. H. Shull, 1909), and

7797-461: The economics of the time, and therefore land management. From 1839 to 1871, the Consulado held a consistent monopolistic position in the regime. Guatemala's "Liberal Revolution" came in 1871 under the leadership of Justo Rufino Barrios , who worked to modernize the country, improve trade, and introduce new crops and manufacturing. During this era coffee became an important crop for Guatemala. Barrios had ambitions of reuniting Central America and took

7910-413: The entire ear is harvested, which requires a separate operation of a maize sheller to remove the kernels from the ear. Whole ears of maize were often stored in corn cribs , sufficient for some livestock feeding uses. Today corn cribs with whole ears, and corn binders, are less common because most modern farms harvest the grain from the field with a combine harvester and store it in bins . The combine with

8023-548: The expansion of the Inca Empire , maize was traded and transported as far south as 40° S in Melinquina, Lácar Department , Argentina, probably brought across the Andes from Chile. After the arrival of Europeans in 1492, Spanish settlers consumed maize, and explorers and traders carried it back to Europe . Spanish settlers much preferred wheat bread to maize. Maize flour could not be substituted for wheat for communion bread, since in Christian belief at that time only wheat could undergo transubstantiation and be transformed into

8136-418: The first " Exposición Centroamericana " ("Central American Fair") in 1897. During his second term, Barrios printed bonds to fund his ambitious plans, fueling monetary inflation and the rise of popular opposition to his regime. His administration also worked on improving the roads, installing national and international telegraphs and introducing electricity to Guatemala City. Completing a transoceanic railway

8249-537: The first presidency, from 1844 to 1848, he brought the country back from excessive conservatism to a moderate regime, and – with the advice of Juan José de Aycinena y Piñol and Pedro de Aycinena – restored relations with the Church in Rome with a Concordat ratified in 1854. After Carrera returned from exile in 1849 the president of El Salvador, Doroteo Vasconcelos , granted asylum to the Guatemalan liberals, who harassed

8362-417: The fortifications of the Guatemalan capital, in place since the battle of Villa Nueva. Taking advantage of Salazar's good faith and Ferrera's weapons, Carrera took Guatemala City by surprise on 13 April 1839; Salazar, Mariano Gálvez and Barrundia fled before the arrival of Carrera's militiamen. Salazar, in his nightshirt, vaulted roofs of neighboring houses and sought refuge, reaching the border disguised as

8475-481: The generals fought under his command, and waited—for a long time—until Carrera's death before beginning their revolt against the tamer Cerna. During Cerna's presidency, liberal party members were prosecuted and sent into exile; among them, those who started the Liberal Revolution of 1871. In 1871, the merchants guild, Consulado de Comercio, lost their exclusive court privilege. They had major effects on

8588-401: The high degree of interaction and cultural diffusion that characterized the region. Advances such as writing, epigraphy , and the calendar did not originate with the Maya; however, their civilization fully developed them. Maya influence can be detected from Honduras , Belize , Guatemala, and Northern El Salvador to as far north as central Mexico, more than 1,000 km (620 mi) from

8701-532: The highly successful double cross hybrids using four inbred lines ( D. F. Jones c. 1918, 1922). University-supported breeding programs were especially important in developing and introducing modern hybrids. Since the 1940s, the best strains of maize have been first-generation hybrids made from inbred strains that have been optimized for specific traits, such as yield, nutrition, drought, pest and disease tolerance. Both conventional cross-breeding and genetic engineering have succeeded in increasing output and reducing

8814-550: The history of the word corn in North America that "[t]o say the word corn is to plunge into the tragi-farcical mistranslations of language and history". Similar to the British usage, the Spanish referred to maize as panizo , a generic term for cereal grains, as did Italians with the term polenta . The British later referred to maize as Turkey wheat, Turkey corn, or Indian corn; Fussell comments that "they meant not

8927-530: The invasion and were in Mataquescuintla – swore they would never forgive Morazán even in his grave; they felt it impossible to respect anyone who would not avenge family members. After sending several envoys, whom Carrera would not receive – and especially not Barrundia whom Carrera did not want to murder in cold blood – Morazán began a scorched-earth offensive, destroying villages in his path and stripping them of assets. The Carrera forces had to hide in

9040-513: The late 20th century by discoveries of monumental architecture from that period, such as the Mirador Basin cities of Nakbé , Xulnal, El Tintal , Wakná and El Mirador . The Classic period of Mesoamerican civilization corresponds to the height of the Maya civilization . It is represented by countless sites throughout Guatemala, although the largest concentration is in Petén . This period

9153-497: The latter would help Guzmán defeat his enemy and also build a port on the Pacific Ocean. Guzmán was sure of victory this time, but his plan evaporated when in his absence Carrera and his native allies occupied Quetzaltenango; Carrera appointed Ignacio Yrigoyen as Corregidor and convinced him that he should work with the K'iche', Q'anjobal and Mam leaders to keep the region under control. On his way out, Yrigoyen murmured to

9266-511: The legislature convened for the election of President Estrada Cabrera, who triumphed thanks to the large number of soldiers and policemen who went to vote in civilian clothes and to the large number of illiterate family that they brought with them to the polls. One of Estrada Cabrera's most famous and most bitter legacies was allowing the entry of the United Fruit Company (UFCO) into the Guatemalan economic and political arena. As

9379-477: The liberal forces of Honduran leader Francisco Morazán and Guatemalan José Francisco Barrundia invaded Guatemala and reached San Sur, where they executed Chúa Alvarez, father-in-law of Rafael Carrera , then a military commander and later the first president of Guatemala. The liberal forces impaled Alvarez's head on a pike as a warning to followers of the Guatemalan caudillo . Carrera and his wife Petrona – who had come to confront Morazán as soon as they learned of

9492-399: The loyalty of a few generals. While the United States threatened intervention if he was removed through revolution, a bipartisan coalition came together to remove him from the presidency. He was removed from office after the national assembly charged that he was mentally incompetent, and appointed Carlos Herrera in his place on 8 April 1920. Guatemala joined with El Salvador and Honduras in

9605-419: The machinery. The combine separates the husk and the cob, keeping only the kernels. Drying is vital to prevent or at least reduce damage by mould fungi, which contaminate the grain with mycotoxins . Aspergillus and Fusarium spp. are the most common mycotoxin sources, and accordingly important in agriculture. If the moisture content of the harvested grain is too high, grain dryers are used to reduce

9718-413: The milk stage, can be arranged either by planting a selection of varieties which ripen earlier and later, or by planting different areas at fortnightly intervals. Maize harvested as a grain crop can be kept in the field a relatively long time, even months, after the crop is ready to harvest; it can be harvested and stored in the husk leaves if kept dry. Before World War II , most maize in North America

9831-427: The moisture content by blowing heated air through the grain. This can require large amounts of energy in the form of combustible gases ( propane or natural gas ) and electricity to power the blowers. Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. In 2020, total world production was 1.16 billion tonnes , led by the United States with 31.0% of

9944-487: The mountains. Believing Carrera totally defeated, Morazán and Barrundia marched to Guatemala City , and were welcomed as saviors by state governor Pedro Valenzuela and members of the conservative Aycinena clan  [ es ] , who proposed to sponsor one of the liberal battalions, while Valenzuela and Barrundia gave Morazán all the Guatemalan resources needed to solve any financial problem he had. The criollos of both parties celebrated until dawn that they finally had

10057-501: The need for cropland, pesticides, water and fertilizer. There is conflicting evidence to support the hypothesis that maize yield potential has increased over the past few decades. This suggests that changes in yield potential are associated with leaf angle, lodging resistance, tolerance of high plant density, disease/pest tolerance, and other agronomic traits rather than increase of yield potential per individual plant. Certain varieties of maize have been bred to produce many ears; these are

10170-400: The new crop. The rise in maize cultivation 500 to 1,000 years ago in what is now the southeastern United States corresponded with a decline of freshwater mussels , which are very sensitive to environmental changes. Because it is cold-intolerant, in the temperate zones maize must be planted in the spring. Its root system is generally shallow, so the plant is dependent on soil moisture. As

10283-465: The north. In the United States, maize was first cultivated at several sites in New Mexico and Arizona about 4,100 years ago. During the first millennium AD, maize cultivation spread more widely in the areas north. In particular, the large-scale adoption of maize agriculture and consumption in eastern North America took place about A.D. 900. Native Americans cleared large forest and grassland areas for

10396-743: The opportunity to shoot Carrera, but did not, because he needed the support of the Guatemalan peasants to counter the attacks of Francisco Ferrera in El Salvador . Instead, Morazán left Carrera in charge of a small fort in Mita, without any weapons. Knowing that Morazán was going to attack El Salvador, Francisco Ferrera gave arms and ammunition to Carrera and convinced him to attack Guatemala City. Meanwhile, despite insistent advice to definitively crush Carrera and his forces, Salazar tried to negotiate with him diplomatically; he even went as far as to show that he neither feared nor distrusted Carrera by removing

10509-539: The population (4.6 million) face food insecurity . Other extant major issues include poverty, crime, corruption, drug trafficking, and civil instability. With an estimated population of around 17.6 million, Guatemala is the most populous country in Central America, the 4th most populous country in North America and the 11th most populous country in the Americas . Its capital and largest city, Guatemala City ,

10622-429: The power to choose his successor. He held that position until he died on 14 April 1865. While he pursued some measures to set up a foundation for economic prosperity to please the conservative landowners, military challenges at home and a three-year war with Honduras, El Salvador, and Nicaragua dominated his presidency. His rivalry with Gerardo Barrios, President of El Salvador, resulted in open war in 1863. At Coatepeque

10735-760: The presence of Starlink genetically modified corn, which had been approved only for animal consumption. The maize genus Zea is relatively closely related to sorghum , both being in the PACMAD clade of Old World grasses, and much more distantly to rice and wheat , which are in the other major group of grasses, the BOP clade . It is closely related to Tripsacum , gamagrass. various grasses e.g. fescue , ryegrass Hordeum (barley) Triticum (wheat) Oryza (rice) Pennisetum (fountaingrasses) Sorghum (sorghum) Tripsacum (gamagrass) Zea mays (maize) other Zea species ( teosintes ) Maize

10848-616: The presidency. There are two different descriptions of how Cabrera was able to become president. The first states that Cabrera entered the cabinet meeting "with pistol drawn" to assert his entitlement to the presidency, while the second states that he showed up unarmed to the meeting and demanded the presidency by virtue of being the designated successor. The first civilian Guatemalan head of state in over 50 years, Estrada Cabrera overcame resistance to his regime by August 1898 and called for elections in September, which he won handily. In 1898

10961-634: The provinces of Central America (excluding Panama, which was then part of Colombia), which had not initially approved becoming part of the Mexican Empire but joined the Empire shortly after their independence. This region was formally a part of the Viceroyalty of New Spain throughout the colonial period, but as a practical matter had been administered separately. It was not until 1825 that Guatemala created its own flag. In 1838

11074-717: The segregated native communities started developing a new Indian identity under Carrera's leadership. In the meantime, in the eastern part of Guatemala, the Jalapa region became increasingly dangerous; former president Mariano Rivera Paz and rebel leader Vicente Cruz were both murdered there after trying to take over the Corregidor office in 1849. When Carrera arrived to Chiantla in Huehuetenango , he received two altenses emissaries who told him that their soldiers were not going to fight his forces because that would lead to

11187-491: The source of the " baby corn " used as a vegetable in Asian cuisine . A fast-flowering variety named mini-maize was developed to aid scientific research, as multiple generations can be obtained in a single year. One strain called olotón has evolved a symbiotic relationship with nitrogen-fixing microbes, which provides the plant with 29%–82% of its nitrogen. The International Maize and Wheat Improvement Center (CIMMYT) operates

11300-415: The stalk. Maize is monoecious , with separate male and female flowers on the same plant. At the top of the stem is the tassel, an inflorescence of male flowers; their anthers release pollen, which is dispersed by wind . Like other pollen, it is an allergen , but most of it falls within a few meters of the tassel and the risk is largely restricted to farm workers. The female inflorescence, some way down

11413-425: The stem from the tassel, is first seen as a silk, a bundle of soft tubular hairs , one for the carpel in each female flower, which develops into a kernel (often called a seed. Botanically, as in all grasses, it is a fruit, fused with the seed coat to form a caryopsis ) when it is pollinated. A whole female inflorescence develops into an ear or corncob , enveloped by multiple leafy layers or husks. The ear leaf

11526-608: The term maize , and the name corn is used mainly in the United States and a handful of other English-speaking countries. In countries that primarily use the term maize , the word corn may denote any cereal crop, varying geographically with the local staple , such as wheat in England and oats in Scotland or Ireland. The usage of corn for maize started as a shortening of " Indian corn " in 18th-century North America. The historian of food Betty Fussell writes in an article on

11639-472: The total (table). China produced 22.4% of the global total. Many pests can affect maize growth and development, including invertebrates, weeds, and pathogens. Maize is susceptible to a large number of fungal, bacterial, and viral plant diseases . Those of economic importance include diseases of the leaf, smuts such as corn smut , ear rots and stalk rots. Northern corn leaf blight damages maize throughout its range, whereas banded leaf and sheath blight

11752-500: The two is largely controlled by differences in just two genes, called grassy tillers-1 ( gt1 , A0A317YEZ1 ) and teosinte branched-1 ( tb1 , Q93WI2 ). In the late 1930s, Paul Mangelsdorf suggested that domesticated maize was the result of a hybridization event between an unknown wild maize and a species of Tripsacum , a related genus; this has been refuted by modern genetic testing . In 2004, John Doebley identified Balsas teosinte, Zea mays subsp. parviglumis , native to

11865-589: The valleys of the Colombian Andes between 7000 and 6000 years ago. The earliest maize plants grew a single, small ear per plant. The Olmec and Maya cultivated maize in numerous varieties throughout Mesoamerica ; they cooked, ground and processed it through nixtamalization . By 3000 years ago, maize was central to Olmec culture, including their calendar, language, and myths. The Mapuche people of south-central Chile cultivated maize along with quinoa and potatoes in pre-Hispanic times. Before

11978-499: Was president of Guatemala from 24 May 1865 to 29 June 1871. Liberal author Alfonso Enrique Barrientos  [ es ] , described Marshall Cerna's government in the following manner: A conservative and archaic government, badly organized and with worse intentions, was in charge of the country, centralizing all powers in Vicente Cerna, ambitious military man, who not happy with the general rank, had promoted himself to

12091-464: Was a main objective of his government, with a goal to attract international investors at a time when the Panama Canal was not yet built. After the assassination of general José María Reina Barrios on 8 February 1898, the Guatemalan cabinet called an emergency meeting to appoint a new successor, but declined to invite Estrada Cabrera to the meeting, even though he was the designated successor to

12204-447: Was an audiencia , a captaincy-general ( Capitanía General de Guatemala ) of Spain, and a part of New Spain (Mexico). The first capital, Villa de Santiago de Guatemala (now known as Tecpan Guatemala ), was founded on 25 July 1524 near Iximché , the Kaqchikel capital city. The capital was moved to Ciudad Vieja on 22 November 1527, as a result of a Kaqchikel attack on Villa de Santiago de Guatemala. Owing to its strategic location on

12317-458: Was harvested by hand. This involved a large number of workers and associated social events (husking or shucking bees ). From the 1890s onward, some machinery became available to partially mechanize the processes, such as one- and two-row mechanical pickers (picking the ear, leaving the stover ) and corn binders, which are reaper-binders designed specifically for maize. The latter produce sheaves that can be shocked . By hand or mechanical picker,

12430-425: Was introduced into Western farming systems, it was welcomed for its productivity. However, a widespread problem of malnutrition soon arose wherever it had become a staple food . Indigenous Americans had learned to soak maize in alkali -water — made with ashes and lime — since at least 1200–1500 BC, creating the process of nixtamalization. They did this to liberate the corn hulls, but coincidentally it also liberated

12543-426: Was led by Guzmán himself and had Florencio Molina and the priest Fernando Davila as his Cabinet members. On 5 September 1848, the criollos altenses chose a formal government led by Fernando Antonio Martínez. In the meantime, Carrera decided to return to Guatemala and did so, entering at Huehuetenango , where he met with native leaders and told them that they must remain united to prevail; the leaders agreed and slowly

12656-466: Was one of the 26 genetically engineered food crops grown commercially in 2016. The vast majority of this is Bt maize . Genetically modified maize has been grown since 1997 in the United States and Canada; by 2016, 92% of the US maize crop was genetically modified. As of 2011, herbicide-tolerant maize and insect-resistant maize varieties were each grown in over 20 countries. In September 2000, up to $ 50 million worth of food products were recalled due to

12769-566: Was strongly allied to the power of regular clergy of the Catholic Church , who were then among the largest landowners in Guatemala. The tight relationship between church and state had been ratified by the Concordat of 1852 , which was the law until Cerna was deposed in 1871. Even liberal generals like Serapio Cruz  [ es ] realized that Rafael Carrera's political and military presence made him practically invincible. Thus
