Alemow
''Citrus macrophylla'', also known as alemow, is a citrus tree and fruit, belonging to the papedas. The trees are short in stature, more tropical in nature than most citrus, and are very spiny. Taxonomy Alemow is rare and poorly studied, a likely hybrid between the citron and biasong (''C. micrantha''). The large fruits are considered inedible by local populations, though the plants are infrequently cultivated for medicinal and other uses. It has been tried in California as a possible rootstock A rootstock is part of a plant, often an underground part, from which new above-ground growth can be produced. It could also be described as a stem with a well developed root system, to which a bud from another plant is grafted. It can refer to ... for other citrus.

Citrus Rootstock
Citrus rootstock are plants used as rootstock for citrus plants. A rootstock plant must be compatible for scion grafting, and resistant to common threats, such as drought, frost, and common citrus diseases. Principal rootstocks Five types of rootstock predominate in temperate climates where cold or freezing weather is not probable, especially Florida and southern Europe: * Sour orange: the only rootstock that truly is an orange (the '' Citrus'' × ''aurantium'' or bitter orange). It is vigorous and highly drought-resistant. * '' Poncirus trifoliata'': a close relative of the genus ''Citrus'', sometimes classified as ''Citrus trifoliata''. It is especially resistant to cold, the tristeza virus, and the oomycete '' Phytophthora parasitica'' (root rot), and grows well in loam soil. Among its disadvantages are its slow growth—it is the slowest growing rootstock—and its poor resistance to heat and drought. It is primarily used in China, Japan, and areas of California with heavy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citrus
''Citrus'' 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 the Austronesian expansion (–1500 BCE). Later, it was spread to the Middle East and the Mediterranean () 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 a wide range of appearance and fruit flavors.

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and other animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; humans, and many other animals, have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language and culinary usage, ''fruit'' normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet (or sour) and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term ''fruit'' als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papeda (citrus)
Papeda or papaeda is the common name for a group of ''Citrus'' species and varieties native to tropical Asia that are hardy and slow-growing, and produce unpalatable fruit. Walter Tennyson Swingle segregated these species into a separate subgenus, ''Papeda'', that included the Ichang lemon, yuzu, kaffir lime, kabosu, sudachi, and a number of wild and uncultivated species and hybrids. Recent genetic analysis shows the papedas to be distributed among distinct branches of the ''Citrus'' phylogenetic tree, and hence Swingle's proposed subgenus is polyphyletic and not a valid taxonomic grouping, but the term persists as a common name. Because of generally slow growth and bitter, less palatable fruits than in other citruses, papeda species have only limited commercial cultivation. Some species, like ichang papeda, are used in landscaping, while others are important for rootstocking and as genome source for breeding disease-resistant and frost-hardy citrus hybrids. In some cases the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citron
The citron (''Citrus medica''), historically cedrate, is a large fragrant citrus fruit with a thick Peel (fruit), rind. It is said to resemble a 'huge, rough lemon'. It is one of the Citrus taxonomy#Citrons, original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial Hybrid (biology), hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used in Asian and Mediterranean cuisine, traditional medicines, perfume, and religious rituals and offerings. Hybrids of citrons with other citrus are commercially more prominent, notably lemons and many Lime (fruit), limes. Etymology The fruit's name is derived from the Latin ''citrus'', which is also the origin of the genus name. Other languages A source of confusion is that '':wikt:citron, 'citron''' in French and English are false friends, as the French word '''citron''' refers to what in English is a lemon; ...

Citrus Micrantha
The micrantha is a wild citrus from the papeda group, native to southern Philippines, particularly islands of Cebu and Bohol. Two varieties are recognized: small-flowered papeda (''C. hystrix'' var. ''micrantha''), locally known as ''biasong'', and small-fruited papeda (''C. hystrix'' var. ''microcarpa'') or ''samuyao''. Although long viewed as a separate species, ''C. micrantha'', it is now generally viewed to fall within '' Citrus hystrix'', but genomic data on the latter is insufficient for a definitive conclusion. A micrantha was one of the progenitor species of some varieties of lime. Description The micrantha was first described to Western science in 1915 by Peter Jansen Wester, who worked for the Philippine Bureau of Agriculture at the time. Biasong Wester collected ripe fruit specimens of biasong (small-flowered papeda, ''Citrus hystrix'' var. ''micrantha'') on islands of Cebu, Bohol, Dumaguete, Negros, and in the Zamboanga and Misamis provinces in Mindan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Citrus Variety Collection
The UCR Citrus Variety Collection (CVC) is one of the most important collections of citrus diversity in the world. It is used for research, plant breeding, and educational extension activities on the UC Riverside campus in Riverside, California. Holdings The collection is composed of over 1000 accessions, planted as two trees of each of various types of citrus and citrus relatives. The collection largely comprises accessions within the genus ''Citrus'', the remaining types are included among 28 other related genera in the Rutaceae subfamily Aurantioideae. The collection consists of approximately on the UCR campus, at the South Coast Research and Extension Center in Irvine, California, and at the Coachella Valley Agricultural Research Station in Thermal, California. It includes accessions that were first introduced in the early 20th century, as well as varieties brought in over time from various curators, and newer varieties that were more recently developed by breeding or br ...
