Citrangequat
The citrangequat is a citrus hybrid of a citrange and a kumquat, developed by Walter Swingle at Eustis, Florida, in 1909. Citrangequats are bitter in taste, but are considered edible by some at the peak of their maturity. Three named cultivars exist: *'Sinton' – Nagami kumquat ('' Fortunella margarita'') x Rusk citrange; named for the city of Sinton, Texas *'Telfair' – Nagami kumquat x Willits citrange; named for Telfair County, Georgia *'Thomasville' – most common citrangequat; named for the city of Thomasville, Georgia Thomasville is the county seat of Thomas County, Georgia, United States. The population was 18,413 at the 2010 United States Census, making it the second largest city in southwest Georgia after Albany. The city deems itself the "City of Roses" an .... 'Thomasville' is considered the most cold-hardy edible citrus variety. It can tolerate temperatures down to −15 °C (5 °F). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citrange
The citrange (a portmanteau of ''citrus'' and ''orange'') is a citrus hybrid of the sweet orange and the trifoliate orange. The purpose of this cross was to attempt to create a cold hardy citrus tree (which is the nature of a trifoliate), with delicious fruit like those of the sweet orange. However, citranges are generally bitter. Citrange is used as a rootstock for citrus in Morocco, but does not prevent dry root rot or exocortis disease. Cultivars There are several named citrange cultivars, including the 'Carrizo' citrange and the 'Troyer' citrange. Both resulted from a hybrid between the trifoliate orange and the Washington navel orange. There is also a cultivar called 'Rusk' which resulted from a cross between a Ruby orange and a trifoliate orange.

Kumquat
Kumquats (; zh, 金桔), or cumquats in Australian English, are a group of small fruit-bearing trees in the flowering plant family Rutaceae. Their taxonomy is disputed. They were previously classified as forming the now-historical genus ''Fortunella'' or placed within ''Citrus'', . Different classifications have alternatively assigned them to anywhere from a single species, ''C. japonica'', to numerous species representing each cultivar. Recent genomic analysis would define three pure species, ''Citrus hindsii'', ''C. margarita'' and ''C. crassifolia'', with ''C. x japonica'' being a hybrid of the last two. The edible fruit closely resembles the orange (''Citrus sinensis'') in color and shape but is much smaller, being approximately the size of a large olive. The kumquat is a fairly cold-hardy citrus. Etymology The English name "kumquat" is a borrowing of the Cantonese ''gāmgwāt'' (). Origin The kumquat plant is native to Southern China. The historical reference to kum ...

Cold-hardy Citrus
Cold-hardy citrus is citrus with increased frost tolerance and which may be cultivated far beyond traditional citrus growing regions. Citrus species and citrus hybrids typically described as cold-hardy generally display an ability to withstand wintertime temperatures below . Cold- hardy citrus may be generally accepted 'true' species (e.g. Satsuma mandarin, kumquat) or hybrids (e.g. citrange) involving various other citrus species. All citrus fruits are technically edible, though some have bitter flavors often regarded as unpleasant, and this variability is also seen in cold-hardy citrus fruits. Those listed as "inedible fresh" or "semi-edible" can (like all citrus) be cooked to make marmalade. Varieties Varieties of true citrus considered cold-hardy, ordered from most to least hardy: Interspecific hybrids Interspecific hybrid varieties considered cold-hardy, ordered from most to least hardy: See also * Citrus rootstock Citrus rootstock are plants used as rootstock f ...

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] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Tennyson Swingle
Walter Tennyson Swingle (January 8, 1871 – January 19, 1952) was an American agricultural botanist who contributed greatly to the classification and taxonomy of citrus. Biography Swingle was born in Canaan, Pennsylvania, and moved with his family to Kansas two years later. He graduated from the Kansas State Agricultural College in 1890, and studied at the University of Bonn in 1895–96 and 1898. Swingle married Lucie Romstaedt in 1901; she died in 1910. He married Maude Kellerman, daughter of William Ashbrook Kellerman, in 1915 and they had four children. He died in Washington, D.C., on January 19, 1952. In 1927, botanist Elmer Drew Merrill published ''Swinglea'', which is a genus of flowering plants from the Philippines, belonging to the family Rutaceae and named in Walter Tennyson Swingle's honor. Contribution to US agricultural industry Swingle worked at the United States Department of Agriculture (1891), investigated subtropic fruits, established laboratories in Flor ...

Taste
The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). Taste is the perception produced or stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with olfaction and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food and other substances. Humans have taste receptors on taste buds and other areas, including the upper surface of the tongue and the epiglottis. The gustatory cortex is responsible for the perception of taste. The tongue is covered with thousands of small bumps called papillae, which are visible to the naked eye. Within each papilla are hundreds of taste buds. The exception to this is the filiform papillae that do not contain taste buds. There are between 2000 and 5000Boron, W.F., E.L. Boulpaep. 2003. Medical Physiology. 1st ed. Elsevier ...

Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...
