In early times, countries in the Mediterranean region were leading producers of these fruits. Ancestral species: This condition is often caused by an excessively high pH (alkaline soil), which prevents the plant from absorbing iron, magnesium, zinc, or other nutrients it needs to produce chlorophyll. For hybrids with kumquats, see citrofortunella. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty about when and where domestication first happened. Abandoned trees in valleys may suffer, yet survive, the dry summer of Central California's Inner Coast Ranges. From the endocarp, string-like "hairs" extend into the locules, which provide nourishment to the fruit as it develops. Wedges of pink grapefruit, lime, and lemon, and a half orange (clockwise from top), Calamansi, a ubiquitous part of traditional dipping sauces and condiments in Philippine cuisine, Ripe bitter oranges (Citrus × aurantium) from Asprovalta, Some Citrus species contain significant amounts of the phytochemical class called furanocoumarins, a diverse family of naturally occurring organic chemical compounds. Be it the fruit or the leaves, kaffir lime is a prominent ingredient in several dishes in Southeast Asia. The colourful outer skin of some citrus fruits, known as zest, is used as a flavouring in cooking; the white inner portion of the peel, the pith, is usually avoided due to its bitterness. Citrus trees grown in tubs and wintered under cover were a feature of Renaissance gardens, once glass-making technology enabled sufficient expanses of clear glass to be produced. Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. According to the UN Food and Agriculture Organization, world production of all citrus fruits in 2016 was 124 million tons, with about half of this production as oranges. In China, fossil leaf specimens of †Citrus linczangensis have been collected from coal-bearing strata of the Bangmai Formation in the Bangmai village, about 10 km northwest of Lincang City, Yunnan. A citrus tree in a container may have to be repotted every 5 years or so, since the roots may form a thick "root-ball" on the bottom of the pot.[38].

If you think you or someone in your family is allergic or sensitive to citrus, the elimination diet is the best way to kee… If you’re watching your calorie intake, citrus fruits are a good … [17] Tasting them is the only way to know whether they are ready to eat. This may be due to perceived similarities in the smell of citrus leaves and fruit with that of cedar. The taxonomy and systematics of the genus are complex and the precise number of natural species is unclear, as many of the named species are hybrids clonally propagated through seeds (by apomixis), and genetic evidence indicates that even some wild, true-breeding species are of hybrid origin. At any age, citrus grows well enough with infrequent irrigation in partial shade, but the fruit crop is smaller. Al's Family Farms Florida Grapefruit, Navel Oranges, Indian River Grapefruit, Honeybells, Florida Oranges, Ruby Red Grapefruit, Indian River Citrus, Orange Fruit. The pulp and rind are also used in cooking and baking. Moreover, the dried peel of mandarin is used in Chinese medicine to treat several health issues. They are a good source of fiber. Citrus fruits have a juicy pulp inside a leathery skin. Lemon juice and lemon peel are used in the food industry all over the world for preparing refreshing juices and tasty desserts. Originating from Southeast Asia, this fruit is a cross between the citrus micrantha and the citrus medica. The citrus family is a large one and it has grown as a result of hybridisation and selection over many centuries. [6], The citron (Citrus medica) was also introduced early into the Mediterranean basin from India and Southeast Asia. A few of the ingredients on the list of citrus fruits and vegetables include oranges, lemons, limes, grapefruit and tangerines, among others. The following are the top reasons why citrus fruit must be incorporated into your diet. In general, three Citrus ancestral species (pomelos, citrons, and papedas) synthesize relatively high quantities of furanocoumarins, whereas a fourth ancestral species (mandarins) is practically devoid of these compounds. In Citrus species, the primary photosensitizing agent appears to be bergapten,[49] a linear furanocoumarin derived from psoralen. Citrus refers to the fruit-bearing shrubs and trees in the family of Rutaceae plants. They contain various plant compounds that serve as safe and all-natural antioxidants and anti-inflammatory agents. Citrus cavaleriei - Ichang papeda The citrus family starts off with just three types of citrus: citrus medica, citrus maxima, and citrus reticulata, also known as citrons, pomelos, and mandarins. The genus Citrus has been suggested to originate in the eastern Himalayan foothills. One review of preliminary research on diets indicated that consuming citrus fruits was associated with a 10% reduction of risk for developing breast cancer.[53]. Apart from these core citrus species, Australian limes and the recently discovered mangshanyegan are grown. They are predominantly native to southeast Asia but also available worldwide. They are bromeliads, a family of plants that grow in soil, typically have stiff, brightly colored leaves, and sometimes produce flowers or fruit. The kumquat has a sweet rind and sour flesh, just the opposite of the closely related citrus fruits. Initially called the ‘Forbidden Fruit’, this citrus was renamed to grapefruit because it grows closely in bunches that look like rather giant grapes. [14], The three ancestral (sometimes characterized as "original" or "fundamental") species in the genus Citrus associated with modern Citrus cultivars are the mandarin orange, pomelo, and citron. They mostly taste sweet with just a hint of sourness. Consistent climate, sufficient sunlight, and proper watering are crucial if the trees are to thrive and produce fruit. (2018) has shown that 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. Fiber improves the digestive system, lowers bad cholesterol levels and helps in weight loss. Blood oranges taste somewhat like sour raspberries. Citrus species include the lemon (Citrus × limon), sour orange (C. × aurantium), sweet orange (C. × sinensis), lime (C. × aurantifolia), tangerine and mandarin orange (C. reticulata), grapefruit (C. × paradisi), and citron (C. … Some modern hobbyists still grow dwarf citrus in containers or greenhouses in areas where the weather is too cold to grow it outdoors. One of the true (non-hybridized) varieties of citrus fruits, the citron is a large yellow-colored fragrant fruit that is widely used in Asian cuisines. Citrus trees are not generally frost hardy. The shriveling leaves eventually fall, and if the plant loses too many, it will slowly die. Sweet limes are excessively used in countries like Pakistan and India for making lemonades. An orangery was a feature of royal and aristocratic residences through the 17th and 18th centuries. More acidic citrus, such as lemons and limes, are generally not eaten on their own. [46][47] In humans, some (not all) of these chemical compounds act as strong photosensitizers when applied topically to the skin, while other furanocoumarins interact with medications when taken orally. Bitter Orange of the citrus family (orange, lemon, mandarin and grapefruit) is one of the most “misunderstood” members of the family. With a production of over 80 million tons each year, oranges are amongst the most widely cultivated fruit tree in the world. 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. This claim has been confirmed for lime[50][51] and bergamot. With oranges, colour cannot be used as an indicator of ripeness because sometimes the rinds turn orange long before the oranges are ready to eat. Citrus medica – Citron Tangerines, tangors and yuzu can be grown outside even in regions with more marked subfreezing temperatures in winter, although this may affect fruit quality. These changes usually involve starches converting to sugars, a decrease in acids, softening, and change in the fruit's colour.[34]. This article may include references and links to products and services from one or more of our advertisers. European brown snails (Cornu aspersum) can be a problem in California, though laying female Khaki Campbell and other mallard-related ducks can be used for control. These fruits are either eaten by simply peeling off the skin, or are squeezed to make juice. The earliest complete description of the citron was first attested from Theophrastus, c. 310 BCE. The real danger lies that the psyllid can carry a deadly, bacterial tree disease called Huanglongbing (HLB), also known as citrus greening disease. [36] According to the United Nations Conference on Trade and Development (UNCTAD), citrus production grew during the early 21st century mainly by the increase in cultivation areas, improvements in transportation and packaging, rising incomes and consumer preference for healthy foods. Mandarins measure 4 to 8 cm in diameter and have a slightly flattened spherical shape. The genus includes famous fruits such as oranges, limes, lemons, and grapefruits to name a few. The space inside each segment is a locule filled with juice vesicles, or "pulp". )", "Foods Indigenous to the Western Hemisphere: Grapefruit", "Food-drug interactions precipitated by fruit juices other than grapefruit juice: An update review", "Chemistry and health effects of furanocoumarins in grapefruit", "The Distribution of Coumarins and Furanocoumarins in, "Toxicological Assessment of Furocoumarins in Foodstuffs", "Citrus fruit intake and breast cancer risk: a quantitative systematic review", Citrus Variety Collection by the University of California, Fundecitrus – Fund for Citrus Plant Protection, "Multilingual Multiscript Plant Name Database (M.M.P.N.D)  – A Work in Progress", University of California Citrus Experiment Station, University of California, Riverside Citrus Variety Collection, https://en.wikipedia.org/w/index.php?title=Citrus&oldid=994008609, Articles with dead external links from August 2019, Articles with permanently dead external links, Articles with dead external links from May 2020, Short description is different from Wikidata, Articles with unsourced statements from December 2014, Wikipedia articles needing factual verification from December 2008, Creative Commons Attribution-ShareAlike License, This page was last edited on 13 December 2020, at 17:52. a hybrid between a sweet orange and a mandarin orange. Citrus × limonia – Rangpur [41], In June 2008, the psyllid was spotted dangerously close to California – right across the international border in Tijuana, Mexico. Citrus × aurantiifolia – Key lime Compared to many of the usual "green shrubs", citrus trees better tolerate poor container care. Citrus × aurantium – Bitter orange The zest of a citrus fruit, typically lemon or an orange, can also be soaked in water in a coffee filter, and drunk. They are also good sources of vitamin C. The content of vitamin C in the fruit depends on the species, variety, and mode of cultivation..[30] Lemons can be commercially grown in cooler-summer/moderate-winter, coastal Southern California, because sweetness is neither attained nor expected in retail lemon fruit. Prior to human cultivation, it consisted of just a few species, though the status of some as distinct species has yet to be confirmed: Sorted by parentage. Citrus reticulata – Mandarin orange For hybrids with the trifoliate orange, see citrange. All types of citrus fruits such as oranges, lemons, limes, and grapefruits belong to the family Rutaceae . Based on the cultivars from which it is harvested, the flesh of grapefruits can be creamy white, pink or even red in color. This species is native to China where it is held in high reverence for various reasons. Citrus linczangensis and C. meletensis share some important characters, such as an intramarginal vein, an entire margin, and an articulated and distinctly winged petiole.[18]. Native to South Asia, sweet lime is a lemon cultivar that was produced by selective breeding. [21] Natural and cultivated citrus hybrids include commercially important fruit such as oranges, grapefruit, lemons, limes, and some tangerines. For cooler winter areas, limes and lemons should not be grown, since they are more sensitive to winter cold than other citrus fruits. Its leaves are heavily used in Thai, Indonesian and Vietnamese cuisines while the fruit is often juiced to for preparing vitalizing drinks, oils for aromatherapy as well as shampoos for treating head lice and other skin problems. This flavonoid (plant compound) makes the blood oranges useful for treating urinary tract infections. These fruits have been cultivated since ancient times. doi:10.1007/BF00984727. Tangier, Morocco. Citrus × latifolia – Persian lime The Bangmai Formation contains abundant fossil plants and is considered to be of late Miocene age. They are drupelike and contain several large seeds. Citrus × paradisi – Grapefruit [24] 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 the presence of essential oil glands. Citrus plants can also develop a deficiency condition called chlorosis, characterized by yellowing leaves[43] highlighted by contrasting leaf veins. This makes it a great fit for commercial purposes. A citrus fruit produced from crossing different hybrids of the citrus reticulata variety, tangelo (sometimes called honeybells) is a round orange fruit with a protruding head.

It was introduced via two ancient trade routes: an overland route through Persia, the Levant and the Mediterranean islands; and a maritime route through the Arabian Peninsula and Ptolemaic Egypt into North Africa. Produced from an accidental cross between a pomelo and sweet orange, the grapefruit was first introduced in Barbados during the mid 18th Century. Florida Pomelo is one of the sweetest citrus fruits worldwide. Citrus fruits are edible fruits that belong to the genus Citrus, and family Rutaceae. A variety of flavours can be derived from different parts and treatments of citrus fruits. Oranges are believed to have originated in ancient China as early as 300 BC. ADDucation’s fruit family list includes some fruits which are commonly believed to be vegetables (avocados, gourds and nightshades) and Rhubarb which is commonly believed to be a fruit but is a vegetable. The trees flower in the spring, and fruit is set shortly afterward. Thus, all commercial citrus cultivation uses trees produced by grafting the desired fruiting cultivars onto rootstocks selected for disease resistance and hardiness. The Key Lime Pie is a popular American dessert that is specially prepared using this variety of citrus fruits. Phylogenetic analysis suggests the species of Oxanthera from New Caledonia should be transferred to the genus Citrus. The genus is commercially important as many species are cultivated for their fruit, which is eaten fresh, pressed for juice, or preserved in marmalades and pickles. Plus, it also has medicinal value and is presented as a religious offering in many countries. The outermost layer of the pericarp is an "exocarp" called the flavedo, commonly referred to as the zest. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. [2][3], 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. Other archaeobotanical evidence include pollen from Carthage dating back to the 4th century BCE; and carbonized seeds from Pompeii dated to around the 3rd to 2nd century BCE. A mix between a lemon and key lime, the Persian Lime is a popular lime species. Citrus × limon – Lemon Don’t be deceived by the name or the appearance – it may be ugly but this fruit does not fall short of flavor. This species was created during the 19th Century in Algeria. The Asian citrus psyllid is an aphid-like insect that feeds on the leaves and stems of citrus trees and other citrus-like plants. [26] They are typically peeled and can be easily split into segments. [2][3][4][5], Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Be it for culinary uses, medicinal purposes, as a cleaning agent or more, lemon is a truly versatile citrus fruit has a huge value in various industries. Although the bright orange colored skin of this fruit is no different than that of a typical orange, the flesh contained within is of deep blood-red color. Pomelo contains pinkish-white flesh that can be sweet, sour or a combination of both.
