The orange is the fruit of the citrus species Citrus × sinensis in the family Rutaceae. It is also called sweet orange, to distinguish it from the related Citrus × aurantium, referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations.
The orange is a hybrid between pomelo (Citrus maxima) and mandarin (Citrus reticulata). The chloroplast genome, and therefore the maternal line, is that of pomelo. The sweet orange has had its full genome sequenced.
Sweet orange originated in ancient China and the earliest mention of the sweet orange was in Chinese literature in 314 BC. As of 1987, orange trees were found to be the most cultivated fruit tree in the world. Orange trees are widely grown in tropical and subtropical climates for their sweet fruit. The fruit of the orange tree can be eaten fresh, or processed for its juice or fragrant peel. As of 2012, sweet oranges accounted for approximately 70% of citrus production.
All citrus trees belong to the single genus Citrus and remain almost entirely interfertile. This includes grapefruits, lemons, limes, oranges, and various other types and hybrids. As the interfertility of oranges and other citrus has produced numerous hybrids and cultivars, and bud mutations have also been selected, citrus taxonomy is fairly controversial, confusing or inconsistent. The fruit of any citrus tree is considered a hesperidium, a kind of modified berry; it is covered by a rind originated by a rugged thickening of the ovary wall.
Different names have been given to the many varieties of the genus. Orange applies primarily to the sweet orange – Citrus sinensis (L.) Osbeck. The orange tree is an evergreen, flowering tree, with an average height of 9 to 10 m (30 to 33 ft), although some very old specimens can reach 15 m (49 ft). Its oval leaves, alternately arranged, are 4 to 10 cm (1.6 to 3.9 in) long and have crenulate margins. Sweet oranges grow in a range of different sizes, and shapes varying from spherical to oblong. Inside and attached to the rind is a porous white tissue, the white, bitter mesocarp or albedo (pith). The orange contains a number of distinct carpels (segments) inside, typically about ten, each delimited by a membrane, and containing many juice-filled vesicles and usually a few seeds (pips). When unripe, the fruit is green. The grainy irregular rind of the ripe fruit can range from bright orange to yellow-orange, but frequently retains green patches or, under warm climate conditions, remains entirely green. Like all other citrus fruits, the sweet orange is non-climacteric. The Citrus sinensis group is subdivided into four classes with distinct characteristics: common oranges, blood or pigmented oranges, navel oranges, and acidless oranges.
Other citrus groups also known as oranges are:
An enormous number of cultivars have, like the sweet orange, a mix of pomelo and mandarin ancestry. Some cultivars are mandarin-pomelo hybrids, bred from the same parents as the sweet orange (e.g. the tangor and ponkan tangerine). Other cultivars are sweet orange x mandarin hybrids (e.g. clementines). Mandarin traits generally include being smaller and oblate, easier to peel, and less acidic. Pomelo traits include a thick white albedo (rind pith, mesocarp) that is more closely attached to the segments.
Orange trees generally are grafted. The bottom of the tree, including the roots and trunk, is called rootstock, while the fruit-bearing top has two different names: budwood (when referring to the process of grafting) and scion (when mentioning the variety of orange).
The word orange derives from the Sanskrit word for "orange tree" (नारङ्ग nāraṅga), which in turn derives from a Dravidian root word (from நரந்தம் narandam which refers to Bitter orange in Tamil). The Sanskrit word reached European languages through Persian نارنگ (nārang) and its Arabic derivative نارنج (nāranj).
The word entered Late Middle English in the fourteenth century via Old French orenge (in the phrase pomme d'orenge). The French word, in turn, comes from Old Provençal auranja, based on Arabic nāranj. In several languages, the initial n present in earlier forms of the word dropped off because it may have been mistaken as part of an indefinite article ending in an n sound—in French, for example, une norenge may have been heard as une orenge. This linguistic change is called juncture loss. The color was named after the fruit, and the first recorded use of orange as a color name in English was in 1512.
As Portuguese merchants were presumably the first to introduce the sweet orange to some regions of Europe, in several modern Indo-European languages the fruit has been named after them. Some examples are Albanian portokall, Bulgarian портокал (portokal), Greek πορτοκάλι (portokali), Macedonian portokal, Persian پرتقال (porteghal), Turkish portakal and Romanian portocală. Related names can be found in other languages, such as Arabic البرتقال (bourtouqal), Georgian ფორთოხალი (pʰortʰoxali) and Amharic birtukan. Also, in some of the Italian regional languages (e.g. Neapolitan), an orange is portogallo or purtuallo, literally "(the) Portuguese (one)", in contrast to the Italian arancia.
In other Indo-European languages, the words for orange allude to the eastern origin of the fruit and can be translated literally as "apple from China". Some examples are German Apfelsine (alternative name for Orange and common in northern Germany), Dutch appelsien and sinaasappel, Swedish apelsin, Russian апельсин (apelsin) and Norwegian appelsin. A similar case is Puerto Rican Spanish china.
The sweet orange is not a wild fruit, having arisen in domestication from a cross between a non-pure mandarin orange and a hybrid pomelo that had a substantial mandarin component. Since its chloroplast DNA is that of pomelo, it was likely the hybrid pomelo, perhaps a BC1 pomelo backcross, that was the maternal parent of the first orange. Based on genomic analysis, the relative proportions of the ancestral species in the sweet orange is approximately 42% pomelo and 58% mandarin. All varieties of the sweet orange descend from this original cross, differing only by mutations selected for during agricultural propagation. Sweet oranges have a distinct origin from the bitter orange, which arose independently, perhaps in the wild, from a cross between pure mandarin and pomelo parents. The earliest mention of the sweet orange in Chinese literature dates from 314 B.C.
In Europe, the Moors introduced the orange to Spain which was known as Al-Andalus, modern Andalusia, with large scale cultivation starting in the 10th century as evidenced by complex irrigation techniques specifically adapted to support orange orchards. Citrus fruits — among them the bitter orange — were introduced to Sicily in the 9th century during the period of the Emirate of Sicily, but the sweet orange was unknown until the late 15th century or the beginnings of the 16th century, when Italian and Portuguese merchants brought orange trees into the Mediterranean area. Shortly afterward, the sweet orange quickly was adopted as an edible fruit. It also was considered a luxury item and wealthy people grew oranges in private conservatories, called orangeries. By 1646, the sweet orange was well known throughout Europe. Louis XIV of France had a great love of orange trees, and built the grandest of all royal Orangeries at the Palace of Versailles. At Versailles potted orange trees in solid silver tubs were placed throughout the rooms of the palace, while the Orangerie allowed year-round cultivation of the fruit to supply the court. When Louis condemned his finance minister, Nicolas Fouquet, in 1664, part of the treasures which he confiscated were over 1,000 orange trees from Fouquet's estate at Vaux-le-Vicomte.
Spanish travelers introduced the sweet orange into the American continent. On his second voyage in 1493, Christopher Columbus may have planted the fruit in Hispaniola. Subsequent expeditions in the mid-1500s brought sweet oranges to South America and Mexico, and to Florida in 1565, when Pedro Menéndez de Avilés founded St Augustine. Spanish missionaries brought orange trees to Arizona between 1707 and 1710, while the Franciscans did the same in San Diego, California, in 1769. An orchard was planted at the San Gabriel Mission around 1804 and a commercial orchard was established in 1841 near present-day Los Angeles. In Louisiana, oranges were probably introduced by French explorers.
Archibald Menzies, the botanist and naturalist on the Vancouver Expedition, collected orange seeds in South Africa, raised the seedlings onboard and gave them to several Hawaiian chiefs in 1792. Eventually, the sweet orange was grown in wide areas of the Hawaiian Islands, but its cultivation stopped after the arrival of the Mediterranean fruit fly in the early 1900s.
Florida farmers obtained seeds from New Orleans around 1872, after which orange groves were established by grafting the sweet orange on to sour orange rootstocks.
The Valencia orange is a late-season fruit, and therefore a popular variety when navel oranges are out of season. This is why an anthropomorphic orange was chosen as the mascot for the 1982 FIFA World Cup, held in Spain. The mascot was named Naranjito ("little orange") and wore the colors of the Spanish national football team.
Thomas Rivers, an English nurseryman, imported this variety from the Azores Islands and catalogued it in 1865 under the name Excelsior. Around 1870, he provided trees to S. B. Parsons, a Long Island nurseryman, who in turn sold them to E. H. Hart of Federal Point, Florida.
This cultivar was discovered by A. G. Hamlin near Glenwood, Florida, in 1879. The fruit is small, smooth, not highly colored, and juicy, with a pale yellow colored juice, especially in fruits that come from lemon rootstock. The fruit may be seedless, or may contain a number of small seeds. The tree is high-yielding and cold-tolerant and it produces good quality fruit, which is harvested from October to December. It thrives in humid subtropical climates. In cooler, more arid areas, the trees produce edible fruit, but too small for commercial use.
Trees from groves in hammocks or areas covered with pine forest are budded on sour orange trees, a method that gives a high solids content. On sand, they are grafted on rough lemon rootstock. The Hamlin orange is one of the most popular juice oranges in Florida and replaces the Parson Brown variety as the principal early-season juice orange. This cultivar is now the leading early orange in Florida and, possibly, in the rest of the world.
Navel oranges are characterized by the growth of a second fruit at the apex, which protrudes slightly and resembles a human navel. They are primarily grown for human consumption for various reasons: their thicker skin makes them easy to peel, they are less juicy and their bitterness – a result of the high concentrations of limonin and other limonoids – renders them less suitable for juice. Their widespread distribution and long growing season have made navel oranges very popular. In the United States, they are available from November to April, with peak supplies in January, February, and March.
According to a 1917 study by Palemon Dorsett, Archibald Dixon Shamel and Wilson Popenoe of the United States Department of Agriculture (USDA), a single mutation in a Selecta orange tree planted on the grounds of a monastery near Bahia, Brazil, probably yielded the first navel orange between 1810 and 1820. Nevertheless, a researcher at the University of California, Riverside, has suggested that the parent variety was more likely the Portuguese navel orange (Umbigo), described by Antoine Risso and Pierre Antoine Poiteau in their book Histoire naturelle des orangers ("Natural History of Orange Trees", 1818–1822). The mutation caused the orange to develop a second fruit at its base, opposite the stem, embedded within the peel of the primary orange. Navel oranges were introduced in Australia in 1824 and in Florida in 1835. In 1870, twelve cuttings of the original tree were transplanted to Riverside, California, where the fruit became known as "Washington". This cultivar was very successful, and rapidly spread to other countries. Because the mutation left the fruit seedless and, therefore, sterile, the only method to cultivate navel oranges was to graft cuttings onto other varieties of citrus trees. The California Citrus State Historic Park and the Orcutt Ranch Horticulture Center preserve the history of navel oranges in Riverside.
Today, navel oranges continue to be propagated through cutting and grafting. This does not allow for the usual selective breeding methodologies, and so all navel oranges can be considered fruits from that single, nearly two-hundred-year-old tree: they have exactly the same genetic make-up as the original tree and are, therefore, clones. This case is similar to that of the common yellow seedless banana, the Cavendish, or that of the Granny Smith apple. On rare occasions, however, further mutations can lead to new varieties.
Cara cara oranges (also called "red navel") are a type of navel orange grown mainly in Venezuela, South Africa and in California's San Joaquin Valley. They are sweet and comparatively low in acid, with a bright orange rind similar to that of other navels, but their flesh is distinctively pinkish red. It is believed that they have originated as a cross between the Washington navel and the Brazilian Bahia navel, and they were discovered at the Hacienda Cara Cara in Valencia, Venezuela, in 1976.
Blood oranges are a natural mutation of C. sinensis, although today the majority of them are hybrids. High concentrations of anthocyanin give the rind, flesh, and juice of the fruit their characteristic dark red color. Blood oranges were first discovered and cultivated in Sicily in the fifteenth century. Since then they have spread worldwide, but are grown especially in Spain and Italy under the names of sanguina and sanguinella, respectively.
The blood orange, with its distinct color and flavor, is generally considered favorably as a juice, and has found a niche as an ingredient variation in traditional Seville marmalade.
Acidless oranges are an early-season fruit with very low levels of acid. They also are called "sweet" oranges in the United States, with similar names in other countries: douce in France, sucrena in Spain, dolce or maltese in Italy, meski in North Africa and the Near East (where they are especially popular), şeker portakal ("sugar orange") in Turkey, succari in Egypt, and lima in Brazil.
The lack of acid, which protects orange juice against spoilage in other groups, renders them generally unfit for processing as juice, so they are primarily eaten. They remain profitable in areas of local consumption, but rapid spoilage renders them unsuitable for export to major population centres of Europe, Asia, or the United States.
Sweet oranges have also given rise to a range of hybrids, notably the grapefruit, which arose from a sweet orange x pomelo backcross. A spontaneous backcross of the grapefruit and sweet orange then resulted in the orangelo. Spontaneous and engineered backcrosses between the sweet orange and mandarin oranges or tangerines has produced a group collectively known as tangors, which includes the clementine and Murcott. More complex crosses have also been produced. The so-called Ambersweet orange is actually a complex sweet orange x (Orlando tangelo x clementine) hybrid, legally designated a sweet orange in the United States so it can be used in orange juices. The citranges are a group of intergeneric sweet orange x trifoliate orange hybrids.
The taste of oranges is determined mainly by the relative ratios of sugars and acids, whereas orange aroma derives from volatile organic compounds, including alcohols, aldehydes, ketones, terpenes, and esters. Bitter limonoid compounds, such as limonin, decrease gradually during development, whereas volatile aroma compounds tend to peak in mid– to late–season development. Taste quality tends to improve later in harvests when there is a higher sugar/acid ratio with less bitterness. As a citrus fruit, the orange is acidic, with pH levels ranging from 2.9 to 4.0.

Oranges contain diverse phytochemicals, including carotenoids (beta-carotene, lutein and beta-cryptoxanthin), flavonoids (e.g. naringenin) and numerous volatile organic compounds producing orange aroma, including aldehydes, esters, terpenes, alcohols, and ketones.
The United States Department of Agriculture (USDA) has established the following grades for Florida oranges, which primarily apply to oranges sold as fresh fruit: US Fancy, US No. 1 Bright, US No. 1, US No. 1 Golden, US No. 1 Bronze, US No. 1 Russet, US No. 2 Bright, US No. 2, US No. 2 Russet, and US No. 3. The general characteristics graded are color (both hue and uniformity), firmness, maturity, varietal characteristics, texture, and shape. Fancy, the highest grade, requires the highest grade of color and an absence of blemishes, while the terms Bright, Golden, Bronze, and Russet concern solely discoloration.
Grade numbers are determined by the amount of unsightly blemishes on the skin and firmness of the fruit that do not affect consumer safety. The USDA separates blemishes into three categories:
The USDA uses a separate grading system for oranges used for juice because appearance and texture are irrelevant in this case. There are only two grades: US Grade AA Juice and US Grade A Juice, which are given to the oranges before processing. Juice grades are determined by three factors:
Like most citrus plants, oranges do well under moderate temperatures—between 15.5 and 29 °C (59.9 and 84.2 °F)—and require considerable amounts of sunshine and water. It has been suggested the use of water resources by the citrus industry in the Middle East is a contributing factor to the desiccation of the region. Another significant element in the full development of the fruit is the temperature variation between summer and winter and, between day and night. In cooler climates, oranges can be grown indoors.
As oranges are sensitive to frost, there are different methods to prevent frost damage to crops and trees when subfreezing temperatures are expected. A common process is to spray the trees with water so as to cover them with a thin layer of ice that will stay just at the freezing point, insulating them even if air temperatures drop far lower. This is because water continues to lose heat as long as the environment is colder than it is, and so the water turning to ice in the environment cannot damage the trees. This practice, however, offers protection only for a very short time. Another procedure is burning fuel oil in smudge pots put between the trees. These devices burn with a great deal of particulate emission, so condensation of water vapour on the particulate soot prevents condensation on plants and raises the air temperature very slightly. Smudge pots were developed for the first time after a disastrous freeze in Southern California in January 1913 destroyed a whole crop.
It is possible to grow orange trees directly from seeds, but they may be infertile or produce fruit that may be different from its parent. For the seed of a commercial orange to grow, it must be kept moist at all times. One approach is placing the seeds between two sheets of damp paper towel until they germinate and then planting them, although many cultivators just set the seeds straight into the soil.
Commercially grown orange trees are propagated asexually by grafting a mature cultivar onto a suitable seedling rootstock to ensure the same yield, identical fruit characteristics, and resistance to diseases throughout the years. Propagation involves two stages: first, a rootstock is grown from seed. Then, when it is approximately one year old, the leafy top is cut off and a bud taken from a specific scion variety, is grafted into its bark. The scion is what determines the variety of orange, while the rootstock makes the tree resistant to pests and diseases and adaptable to specific soil and climatic conditions. Thus, rootstocks influence the rate of growth and have an effect on fruit yield and quality.
Rootstocks must be compatible with the variety inserted into them because otherwise, the tree may decline, be less productive, or die.
Among the several advantages to grafting are that trees mature uniformly and begin to bear fruit earlier than those reproduced by seeds (3 to 4 years in contrast with 6 to 7 years), and that it makes it possible to combine the best attributes of a scion with those of a rootstock.
Canopy-shaking mechanical harvesters are being used increasingly in Florida to harvest oranges. Current canopy shaker machines use a series of six-to-seven-foot-long tines to shake the tree canopy at a relatively constant stroke and frequency.
Normally, oranges are picked once they are pale orange.
Oranges must be mature when harvested. In the United States, laws forbid harvesting immature fruit for human consumption in Texas, Arizona, California and Florida. Ripe oranges, however, often have some green or yellow-green color in the skin. Ethylene gas is used to turn green skin to orange. This process is known as "degreening", also called "gassing", "sweating", or "curing". Oranges are non-climacteric fruits and cannot post-harvest ripen internally in response to ethylene gas, though they will de-green externally.
Commercially, oranges can be stored by refrigeration in controlled-atmosphere chambers for up to twelve weeks after harvest. Storage life ultimately depends on cultivar, maturity, pre-harvest conditions, and handling. In stores and markets, however, oranges should be displayed on non-refrigerated shelves.
The first major pest that attacked orange trees in the United States was the cottony cushion scale (Icerya purchasi), imported from Australia to California in 1868. Within 20 years, it wiped out the citrus orchards around Los Angeles, and limited orange growth throughout California. In 1888, the USDA sent Alfred Koebele to Australia to study this scale insect in its native habitat. He brought back with him specimens of Novius cardinalis, an Australian ladybird beetle, and within a decade the pest was controlled.
The citrus greening disease, caused by the bacterium Liberobacter asiaticum, has been the most serious threat to orange production since 2010. It is characterized by streaks of different shades on the leaves, and deformed, poorly colored, unsavory fruit. In areas where the disease is endemic, citrus trees live for only five to eight years and never bear fruit suitable for consumption. In the western hemisphere, the disease was discovered in Florida in 1998, where it has attacked nearly all the trees ever since. It was reported in Brazil by Fundecitrus Brasil in 2004. As from 2009, 0.87% of the trees in Brazil's main orange growing areas (São Paulo and Minas Gerais) showed symptoms of greening, an increase of 49% over 2008.
The disease is spread primarily by two species of psyllid insects. One of them is the Asian citrus psyllid (Diaphorina citri Kuwayama), an efficient vector of the Liberobacter asiaticum. Generalist predators such as the ladybird beetles Curinus coeruleus, Olla v-nigrum, Harmonia axyridis, and Cycloneda sanguinea, and the lacewings Ceraeochrysa spp. and Chrysoperla spp. make significant contribution to the mortality of the Asian citrus psyllid, which results in 80–100% reduction in psyllid populations. In contrast, parasitism by Tamarixia radiata, a species-specific parasitoid of the Asian citrus psyllid, is variable and generally low in southwest Florida: in 2006, it amounted to a reduction of less than 12% from May to September and 50% in November.
In 2007, foliar applications of insecticides reduced psyllid populations for a short time, but also suppressed the populations of predatory ladybird beetles. Soil application of aldicarb provided limited control of Asian citrus psyllid, while drenches of imidacloprid to young trees were effective for two months or more.
Management of citrus greening disease is difficult and requires an integrated approach that includes use of clean stock, elimination of inoculum via voluntary and regulatory means, use of pesticides to control psyllid vectors in the citrus crop, and biological control of psyllid vectors in non-crop reservoirs. Citrus greening disease is not under completely successful management.
Greasy spot, a fungal disease caused by the Mycosphaerella citri, produces leaf spots and premature defoliation, thus reducing the tree's vigour and yield. Ascospores of M. citri are generated in pseudothecia in decomposing fallen leaves. Once mature, ascospores are ejected and subsequently dispersed by air currents.
|Production of oranges – 2016|
|Country||Production (millions of tonnes)|
|People's Republic of China|
Brazil is the world's leading orange producer, with an output of 17 million tonnes, followed by China, India, and the United States as the four major producers. As almost 99% of the fruit is processed for export, 53% of total global frozen concentrated orange juice production comes from this area and the western part of the state of Minas Gerais. In Brazil, the four predominant orange varieties used for obtaining juice are Hamlin, Pera Rio, Natal, and Valencia.
In the United States, groves are located mainly in Florida, California, and Texas. The majority of California's crop is sold as fresh fruit, whereas Florida's oranges are destined to juice products. The Indian River area of Florida is known for the high quality of its juice, which often is sold fresh in the United States and frequently blended with juice produced in other regions because Indian River trees yield very sweet oranges, but in relatively small quantities.
Production of orange juice between the São Paulo and mid-south Florida areas makes up roughly 85% of the world market. Brazil exports 99% of its production, while 90% of Florida's production is consumed in the United States.
Orange juice is traded internationally in the form of frozen, concentrated orange juice to reduce the volume used so that storage and transportation costs are lower.
Oranges, whose flavor may vary from sweet to sour, are commonly peeled and eaten fresh or squeezed for juice. The thick bitter rind is usually discarded, but can be processed into animal feed by desiccation, using pressure and heat. It also is used in certain recipes as a food flavoring or garnish. The outermost layer of the rind can be thinly grated with a zester to produce orange zest. Zest is popular in cooking because it contains oils and has a strong flavor similar to that of the orange pulp. The white part of the rind, including the pith, is a source of pectin and has nearly the same amount of vitamin C as the flesh and other nutrients.
Although not as juicy or tasty as the flesh, orange peel is edible and has significant contents of vitamin C, dietary fiber, total polyphenols, carotenoids, limonene and dietary minerals, such as potassium and magnesium.
Aurum is a sweet Italian liqueur produced in Pescara since 1925. It is 40% alcohol by volume and it is made from brandy and citrus fruit infusion.
It goes well with sweets, especially with parrozzo, another specialty of Pescara. Other than as a drink, it is often used as a cake ingredient or as an addition to ice-cream.
The name of this liqueur was chosen by Amedeo Pomilio, the founder of the Aurum factory, upon suggestion by the poet and writer Gabriele D'Annunzio, with a reference to the ancient Roman origins of the recipe. The name derives from the pun between the Latin words aurum, which means gold, and aurantium, which means orange (fruit).

Citra is an unincorporated community in Marion County, Florida, United States. The community is part of the Ocala Metropolitan Statistical Area. Citra is known as the home of the pineapple orange, (originally called the Hickory orange) a name coined in 1883 for an orange (fruit) with an aroma reminiscent of the pineapple.Crataegus azarolus
Crataegus azarolus is a species of hawthorn known by the common names azarole, azerole, and Mediterranean medlar. It is native to the Mediterranean Basin and is a common plant there, growing on sites comparable to those the European common hawthorn grows on. In the Arab countries it is the commonest of the hawthorn species; in the Arabic language the term "common hawthorn" means the azarole hawthorn. When growing in the wild the azerole bears plentiful crops of haw fruits, which are similar to the haws of the European common hawthorn, but plumper.
C. azarolus is often divided into subspecies or varieties, for example Christensen in his monograph uses four varieties:
C. azarolus var. azarolus has orange fruit.
C. azarolus var. aronia L., has yellowish fruit often with some red tinges
C. azarolus var. chlorocarpa (Moris) K.I.Chr. has yellowish fruit
C. azarolus var. pontica (K.Koch) K.I.Chr. has yellowish or orange fruitC. azarolus has been used historically for a number of medicinal purposes.Garut orange
Garut Oranges are a fruit variety grown in Indonesia's mountains and hilly areas in Garut Regency at Wanaraja, Samarang and Bayongbong Districts. These locations feature mountains or hilly areas, with highland views of more than 900 m (2,953 ft.) above sea level. Many kinds of fruits and vegetables compete for this growing area.
When Indonesia was a Dutch colony, Garut Oranges were considered one of Indonesia's most famous exotic fruits.
Garut Oranges have a good taste, good coloring, thick skin textures, and good aroma. Crops have been significantly damaged by Citrus Vein Phloem Degeneration (CVPD).Giant pumpkin

The town's main celebrations occur in May (5-15) to note the Batalla de Puebla, and in July to honor to San Cristobal, the town's Patron Saint.
The area's climate is warm and rainy, with more rain in summer and autumn.Mandarin orange
The mandarin orange (Citrus reticulata), also known as the mandarin or mandarine, is a small citrus tree with fruit resembling other oranges, usually eaten plain or in fruit salads. Reddish-orange mandarin cultivars can be marketed as tangerines, but this is not a botanical classification.
Mandarins are smaller and oblate, rather than spherical, like the common oranges (which are a mandarin hybrid). The taste is considered less sour, as well as sweeter and stronger. A ripe mandarin is firm to slightly soft, heavy for its size, and pebbly-skinned. The peel is thin, with little white mesocarp, so they are usually easier to peel and to split into segments. Hybrids generally have these traits to a lesser degree. The mandarin is tender and is damaged easily by cold. It can be grown in tropical and subtropical areas.According to genetic studies, the mandarin, the citron, pomelo, papedas, and kumquat, were ancestors of citrus varieties, and through breeding or natural hybridization, were developed as a sweet fruit among the parental species. A major commercial variety, commonly classified as a tangerine, is called the Clementine which resulted as a chance hybrid attributed to Father Clement Rodier in 1902.Moloacán

One of the most colorful doves, the male has a golden olive head and elongated bright orange "hair-like" body feathers. The golden-olive remiges are typically covered by the long orange wing coverts when perched. The legs, bill and orbital skin are bluish-green and the iris is whitish. The female is a dark green bird with blackish tail and orange-yellow undertail coverts. The young resembles females.
The orange dove is endemic to forests of Vanua Levu, Taveuni, Rabi, Kioa, Qamea and Laucala islands of Fiji. The diet consists mainly of various small fruits, berries, caterpillars and insects. The female usually lays one white egg. The orange fruit dove is closely related to the whistling fruit dove and golden fruit dove. These species are allopatric, meaning they do not share the same habitat in any location. A common species throughout its limited range, the orange fruit dove is evaluated as Least Concern on the IUCN Red List of Threatened Species.Orange oil

In contrast to most essential oils, it is extracted as a by-product of orange juice production by centrifugation, producing a cold-pressed oil. It is composed of mostly (greater than 90%) d-limonene, and is often used in place of pure d-limonene. D-limonene can be extracted from the oil by distillation.Spongiforma squarepantsii
Spongiforma squarepantsii is a species of fungus in the Boletaceae family, genus Spongiforma. Found in Malaysia, it was described as new to science in 2011. It produces sponge-like, rubbery orange fruit bodies that have a fruity or musky odour. The fruit bodies reach dimensions of 10 cm (3.9 in) wide by 7 cm (2.8 in) tall. Like a sponge, they will resume their original shape if water is squeezed out. The spores, produced on the surfaces of the hollows of the sponge, are almond-shaped with rough surfaces, and measure 10–12.5 by 6–7 micrometers. The name of the fungus is derived from the cartoon character SpongeBob SquarePants from the show of the same name. S. squarepantsii is one of two species in Spongiforma; it differs from S. thailandica in its color, odour, and spore structure.Woodford's fruit bat
