The total population of Cayo's rural areas was of 36,747; 18,864 males and 17,883 females. 8,029 total households and a 4.6 average household size. 16°50′N 88°55′W  /  16.833°N 88.917°W  / 16.833; -88.917 Citrus Ancestral species: Citrus maxima – Pomelo Citrus medica – Citron Citrus reticulata – Mandarin orange Citrus micrantha –

176-458: A high quantity of citric acid , which with other organic acids including ascorbic acid (vitamin C) give them their characteristic sharp taste. Citrus fruits are diverse in size and shape, as well as in color and flavor, reflecting their biochemistry; for instance, grapefruit is made bitter-tasting by a flavanone, naringin . Most commercial citrus cultivation uses trees produced by grafting

220-576: A linear furanocoumarin derived from psoralen . This claim has been confirmed for lime and bergamot . In particular, bergamot essential oil has a higher concentration of bergapten (3–3.6 g/kg) than any other Citrus -based essential oil. A systematic review indicates that citrus fruit consumption is associated with a 10% reduction of risk for developing breast cancer. Many citrus fruits, such as oranges , tangerines , grapefruits , and clementines , are generally eaten fresh. They are typically peeled and can be easily split into segments. Grapefruit

264-600: A north-north-easterly direction to the highest point on the Humming Bird Highway in the Humming Bird Gap; thence by the southern side of the Humming Bird Highway in a westerly direction to a point 70 chains east of St. Margaret's Creek bridge measured along the Highway; thence in a straight line in a northerly direction to the source of the westernmost tributary of Indian Creek; thence downward along

308-491: A small number of core ancestral species, including the citron, pomelo, and mandarin. Natural and cultivated citrus hybrids include commercially important fruit such as oranges, grapefruit , lemons, limes, and some tangerines . The multiple hybridisations have made the taxonomy of Citrus complex. Apart from these core species, Australian limes and the recently discovered mangshanyegan are grown. Kumquats and Clymenia spp. are now generally considered to belong within

352-460: A wasp on one of the fruits. The impressionist Edouard Manet depicted a lemon on a pewter plate. In modern art, Arshile Gorky painted Still Life with Lemons in the 1930s. Citrus fruits "were the clear status symbols of the nobility in the ancient Mediterranean", according to the paleoethnobotanist Dafna Langgut. In Louisa May Alcott 's 1868 novel Little Women , the character Amy March states that "It's nothing but limes now, for everyone

396-460: A wide range of appearance and fruit flavors. The large citrus fruit of today evolved originally from small, edible berries over millions of years. Citrus species began to diverge from a common ancestor about 15 million years ago, at about the same time that Severinia (such as the Chinese box orange ) diverged from the same ancestor. About 7 million years ago, the ancestors of Citrus split into

440-485: Is a genus of flowering trees and shrubs in the family Rutaceae . Plants in the genus produce citrus fruits , including important crops such as oranges , mandarins , lemons , grapefruits , pomelos , and limes . Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia , and Australia. Indigenous people in these areas have used and domesticated various species since ancient times. Its cultivation first spread into Micronesia and Polynesia through

484-428: Is also an integral part of the region's economy. Politically, Cayo is divided into six constituencies , described in detail here: Cayo District contains several pre-Columbian mayan ruins and sites, among these are Caracol , Xunantunich , Cahal Pech , Baking Pot , Lower Dover and El Pilar . According to the 2010 Population and Housing Census, Cayo District's total population is of 73,202 residents (compared to

528-477: Is more commonly halved and eaten out of the skin with a spoon. Lemonade is a popular beverage prepared by diluting the juice and adding sugar. Lemon juice is mixed in salad dressings and squeezed over fruit salad to stop it from turning brown: its acidity suppresses oxidation by polyphenol oxidase enzymes. A variety of flavours can be derived from different parts and treatments of citrus fruits. The colourful outer skin of some citrus fruits, known as zest ,

572-1007: Is now in production. There are two major highways in the District, the George Price Highway , that runs from Belize City to the Guatemalan border, and the Hummingbird Highway which starts in Belmopan and ends at the juncture of the Coastal Road and the Southern Highway that ends in the Stann Creek District . In addition to the ruins listed above there are several other important nature reserves including two National Parks, Blue Hole and Guanacaste National Park . Ecotourism

616-580: Is used as a flavouring in cooking. The whole of the bitter orange (and sometimes other citrus fruits) including the peel with its essential oils is cooked with sugar to make marmalade . By the 17th century, orangeries were added to great houses in Europe, both to enable the fruit to be grown locally and for prestige, as seen in the Versailles Orangerie . Some modern hobbyists grow dwarf citrus in containers or greenhouses in areas where

660-698: The Austronesian expansion ( c.  3000 –1500 BCE). Later, it was spread to the Middle East and the Mediterranean ( c.  1200 BCE ) via the incense trade route , and from Europe to the Americas. Renowned for their highly fragrant aromas and complex flavor, citrus are among the most popular fruits in cultivation. With a propensity to hybridize between species, making their taxonomy complicated, there are numerous varieties encompassing

704-740: The Philippines . This was followed by the spread of citrus species into Taiwan and Japan in the Early Pliocene (5.33 to 3.6 mya ), resulting in the tachibana orange ( C. tachibana ); and beyond the Wallace Line into Papua New Guinea and Australia during the Early Pleistocene (2.5 million to 800,000 years ago), where further speciation events created in the Australian limes . A fossil leaf from

748-640: The Pliocene of Valdarno , Italy is described as † Citrus meletensis . In China, fossil leaf specimens of † Citrus linczangensis have been collected from late Miocene coal-bearing strata of the Bangmai Formation in Yunnan province. C. linczangensis resembles C. meletensis in having an intramarginal vein, an entire margin, and an articulated and distinctly winged petiole . Many cultivated Citrus species are natural or artificial hybrids of

792-665: The citron ( C. medica ) or a conifer tree ( Thuja ). The Latin word is related to the ancient Greek word for the cedar of Lebanon , κέδρος ( kédros ), perhaps from a perceived similarity of the smell of citrus leaves and fruit with that of cedar. Citrus plants are large shrubs or small to moderate-sized trees, reaching 5–15 m (16–49 ft) tall, with spiny shoots and alternately arranged evergreen leaves with an entire margin. The flowers are solitary or in small corymbs , each flower 2–4 cm (0.79–1.57 in) diameter, with five (rarely four) white petals and numerous stamens; they are often very strongly scented, due to

836-421: The citrons ( Citrus medica ) of South Asia; the pomelos ( C. maxima ) of Mainland Southeast Asia ; the mandarins ( C. reticulata ), kumquats ( C. japonica ), mangshanyegan ( C. mangshanensis ), and ichang papedas ( C. cavaleriei ) of southeastern China; the kaffir limes ( C. hystrix ) of Island Southeast Asia ; and the biasong and samuyao ( C. micrantha ) of

924-655: The Mediterranean by Arab traders around the 10th century CE. Sweet oranges were brought to Europe by the Genoese and Portuguese from Asia during the 15th to 16th century. Mandarins were not introduced until the 19th century. Oranges were introduced to Florida by Spanish colonists. In cooler parts of Europe, citrus fruit was grown in orangeries starting in the 17th century; many were as much status symbols as functional agricultural structures. The generic name Citrus originates from Latin , where it denoted either

968-529: The center of origin of the genus Citrus is likely the southeast foothills of the Himalayas , in a region stretching from eastern Assam , northern Myanmar , to western Yunnan . It diverged from a common ancestor with Poncirus trifoliata . A change in climate conditions during the Late Miocene (11.63 to 5.33 mya ) resulted in a sudden speciation event . The species resulting from this event include

1012-495: The courses of Indian Creek and Sibun River to the mouth of Nancy Porter Creek; thence in a straight line to the point of commencement. As of 2020, these are still the boundaries used for the District. Cayo District is primarily an agricultural district, with the chief crops being citrus fruit (more specifically, oranges, grapefruit, and tangerine ), as well as bananas. Recently, oil was found in Spanish Lookout and it

1056-463: The damaging citrus tristeza virus , while the aphid-like Asian citrus psyllid can carry the bacterium which causes the serious citrus greening disease . This threatens production in Florida, California, and worldwide. Citrus groves are attacked by parasitic Nematodes including citrus ( Tylenchulus semipenetrans ) and sheath nematodes ( Hemicycliophora spp.). Citrus plants can develop

1100-432: The deficiency condition chlorosis , characterized by yellowing leaves. The condition is often caused by an excessively high pH ( alkaline soil ), which prevents the plant from absorbing nutrients such as iron, magnesium , and zinc needed to produce chlorophyll . Some Citrus species contain significant amounts of furanocoumarins . In humans, some of these act as strong photosensitizers when applied topically to

1144-415: The desired fruiting cultivars onto rootstocks selected for disease resistance and hardiness. The trees are not generally frost hardy. They thrive in a consistently sunny, humid environment with fertile soil and adequate water. The colour of citrus fruits only develops in climates with a ( diurnal ) cool winter. In tropical regions with no winter at all, citrus fruits remain green until maturity, hence

1188-465: The district include Benque Viejo del Carmen , twin towns of San Ignacio and Santa Elena (District's Capital), Seven Miles (El Progreso), San Antonio , Valley of Peace , St. Margaret , Roaring Creek , Armenia , San Jose Succotz , Arenal , Buena Vista , Bullet Tree Falls , Calla Creek , Esperanza , Cristo Rey , Georgeville, Unitedville , Blackman Eddy , Ontario , Camalote , Los Tambos , More Tomorrow and Spanish Lookout . Major rivers in

1232-779: The district include the Macal River and the Mopan River . In 1960, the boundaries of the Cayo District were defined as follows: Commencing at Big Falls, Belize River; thence upward along the course of the Belize River to Labouring Creek, Yalbac Creek and Tu-Tu Creek to the Western Frontier Line; thence following the Frontier Line southward to the crossing of the main divide or watershed of

1276-451: The district's 2000 population of 53,715); of whom 36,803 are males and 36,399 are females. The total number of households is 15,497 and the average household size is 4.7. The southern half of Cayo District is very low densely populated. A large majority of the district's population lives north of the 17th parallel . In 2010, the total population of Cayo's urban areas was of 36,455; 17,939 males and 18,516 females. 7,468 total households and

1320-523: The earliest evidence are seeds recovered from the Hala Sultan Tekke site of Cyprus , dated to around 1200 BCE. Other archaeobotanical evidence includes pollen from Carthage dating back to the 4th century BCE; and carbonized seeds from Pompeii dated to around the 3rd to 2nd century BCE. The earliest complete description of the citron was written by Theophrastus , c.  310 BCE . Lemons, pomelos, and sour oranges were introduced to

1364-756: The early 21st century mainly by the increase in cultivation areas, improvements in transportation and packaging, rising incomes and consumer preference for healthy foods. In 2019–20, world production of oranges was estimated to be 47.5 million tonnes, led by Brazil, Mexico, the European Union, and China as the largest producers. Among the diseases of citrus plantations are citrus black spot (a fungus), citrus canker (a bacterium), citrus greening (a bacterium, spread by an insect pest), and sweet orange scab (a fungus, Elsinöe australis ). Citrus plants are liable to infestation by ectoparasites which act as vectors to plant diseases: for example, aphids transmit

1408-761: The genus Citrus associated with modern Citrus cultivars are the mandarin orange , pomelo , and citron . Almost all of the common commercially important citrus fruits (sweet oranges, lemons, grapefruit, limes, and so on) are hybrids between these three species, their main progenies, and other wild Citrus species within the last few thousand years. Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia , Near Oceania , and northeastern and central Australia. Domestication of citrus species involved much hybridization and introgression , leaving much uncertainty about when and where domestication first happened. A genomic, phylogenic, and biogeographical analysis by Wu et al. (2018) has shown that

1452-555: The genus Citrus . The false oranges, Oxanthera from New Caledonia , have been transferred to the Citrus genus on phylogenetic evidence. The earliest introductions of citrus species by human migrations was during the Austronesian expansion ( c.  3000 –1500 BCE), where Citrus hystrix , Citrus macroptera , and Citrus maxima were among the canoe plants carried by Austronesian voyagers eastwards into Micronesia and Polynesia . The citron ( Citrus medica )

Cayo District Being the largest district, it borders Guatemala to the west, Orange Walk district to the north, Belize district to the northeast, Stann Creek district to the southeast and Toledo district to the south. The nation's capital, Belmopan , is located within the district. Other important towns and cities in

1540-453: The locules, which provide nourishment to the fruit as it develops. The genus is commercially important with cultivars of many species grown for their fruit. Some cultivars have been developed to be easy to peel and seedless, meaning they are parthenocarpic . The fragrance of citrus fruits is conferred by flavonoids and limonoids in the rind. The flavonoids include various flavanones and flavones . The carpels are juicy; they contain

1584-557: The main genus, Citrus , and the genus Poncirus (such as the trifoliate orange ), which is closely enough related that it can still be hybridized with all other citrus and used as rootstock. These estimates are made using genetic mapping of plant chloroplasts . A DNA study published in Nature in 2018 concludes that the genus Citrus evolved in the foothills of the Himalayas , in the area of Assam (India), western Yunnan (China), and northern Myanmar . The three ancestral species in

1628-410: The pericarp is the mesocarp, which in citrus fruits consists of the white, spongy albedo or pith. The innermost layer of the pericarp is the endocarp. This surrounds a variable number of carpels , shaped as radial segments. The seeds, if present, develop inside the carpels. The space inside each segment is a locule filled with juice vesicles , or pulp. From the endocarp, string-like "hairs" extend into

1672-403: The presence of essential oil glands. The fruit is a hesperidium , a specialised berry with multiple carpels , globose to elongated, 4–30 cm (1.6–11.8 in) long and 4–20 cm (1.6–7.9 in) diameter, with a leathery rind or "peel" called a pericarp . The outermost layer of the pericarp is an "exocarp" called the flavedo , commonly referred to as the zest . The middle layer of

1716-601: The production and release of ethylene is gradual. According to the UN Food and Agriculture Organization , world production of all citrus fruits in 2016 was 124 million tonnes, with about half of this production as oranges. At US $ 15.2 billion equivalent in 2018, citrus trade makes up nearly half of the world fruit trade, which was US$ 32.1 billion that year. According to the United Nations Conference on Trade and Development , citrus production grew during

1760-449: The skin, while others interact with medications when taken orally in the grapefruit juice effect . Due to the photosensitizing effects of certain furanocoumarins, some Citrus species cause phytophotodermatitis , a potentially severe skin inflammation resulting from contact with a light-sensitizing botanical agent followed by exposure to ultraviolet light. In Citrus species, the primary photosensitizing agent appears to be bergapten ,

1804-480: The tropical "green oranges". The terms 'ripe' and 'mature' are widely used synonymously, but they mean different things. A mature fruit is one that has completed its growth phase. Ripening is the sequence of changes within the fruit from maturity to the beginning of decay. These changes involve the conversion of starches to sugars, a decrease in acids, softening, and s change in the fruit's colour. Citrus fruits are non- climacteric and respiration slowly declines and
