Citrus Macrophylla
''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 for other citrus.

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ... [...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 ski ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citron
The citron (''Citrus medica''), historically cedrate, is a large fragrant citrus fruit with a thick rind. It is said to resemble a 'huge, rough lemon'. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used in Asian cuisine, traditional medicines, perfume, and religious rituals and offerings. Hybrids of citrons with other citrus are commercially more prominent, notably lemons and many limes. Etymology The fruit's English name "citron" derives ultimately from Latin, ''citrus'', which is also the origin of the genus name. Other languages A source of confusion is that ''citron'' in French and English are false friends, as the French word refers to the lemon, while the English word is translated ''cédrat''. Indeed, into the 16th century, the English name ''citron'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''. 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 Mindanao. The frui ...

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 fungus '' 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 soils. ... [...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 Aurantiodeae. 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 ...
