Hyuganatsu
Hyuganatsu (''Citrus tamurana'', Japanese: 日向夏) is a citrus fruit and plant grown in Japan. The name comes from Hyūga, the ancient name of Miyazaki Prefecture in Kyushu, where the citrus is said to have originated, while means summer. Hyūganatsu grown outside Kyushu are sometimes shipped under different names such as , , or . Origin A hyūganatsu sapling was said to have been found in a Miyazaki garden sometime in the 1820s, after which it became widely cultivated throughout the region. It is theorized to be either a mutated yuzu or perhaps more likely, a chance hybrid between yuzu and pomelo. Description The fruit is of medium size and its shape is round to slightly oblong. When ripe, it turns a light yellow. Its flesh is juicy and sweet with a slightly sour taste. It is usually eaten cut up, sprinkled with sugar and with most of its rather thick pith intact. The fruit's oil is higher than other citrus fruits in trans-β-farnesene, l-carvone, and has a higher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ōgonkan
or are the common names for a small sized variety of Japanese citrus, whose rind is of a characteristic "golden" bright yellow color. The variety has been published as the species ''Citrus flaviculpus'' by Chōzaburō Tanaka in his 160-species scheme, but this is considered an effort of a " splitter", as opposed to Swingle's classification system which is generally preferred in the West. Alternate spellings (romanizations) include "Ougonkan" or "Ogon-kan". It has also been called "Golden orange" in Kanagawa Prefecture. History The variety has long been known in Kagoshima Prefecture as but, precise origins are unknown. According to one assertion, it has been known in Higashi-ichiki-chō ( ja) and its neighborhood (now Hioki, Kagoshima) since the Meiji Period. Anecdotally in this Hioki area, the variety is said to have been either introduced by the Jesuit Francisco de Xavier, or brought back from the Korean Peninsula during Hideyoshi's invasions of Korea in the late 16t ...

Japanese Citrus
Japanese citrus fruits were first mentioned in the ''Kojiki'' and ''Nihonshoki'', compiled in the 700s, and the ''Man'yōshū'' and ''Kokin Wakashū'', poetry anthologies compiled in the 700s and 900s, mention the Tachibana orange as a subject of ''Waka (poetry), waka'' poetry and describe its use as a medicinal, ornamental, and incense plant. Throughout their history, the Japanese have created and cultivated various varieties of citrus fruits, taking advantage of the mild climate that is ideal for growing citrus. In particular, from the 1600s during the Edo period (1603–1868) to the present, various varieties of citrus fruits have been produced, including Citrus unshiu, Unshū, :ja:ナツミカン, Natsumikan, Hassaku, Iyokan, and Dekopon. At present, Unshū is the most widely grown in Japan, and various cultivars have been developed. At present, the largest citrus growing areas are located in the Prefectures of Japan, prefectures of Wakayama Prefecture, Wakayama, Shizuoka P ...

Plantae
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Yuzu
Yuzu (''Citrus'' × ''junos'', from Japanese language, Japanese or ; ) is a citrus fruit and plant in the family Rutaceae of China, Chinese origin. Yuzu has been cultivated mainly in East Asia, though it has also recently been grown in New Zealand, Australia, Spain, Italy, and France. It is believed to have originated in central China as an F1 hybrid of the ( zh, t=莽山野橘) subspecies of mandarin orange and the ichang papeda. and Supplement Description This fruit resembles a yellow clementine with uneven skin and can be either yellow or green depending on the degree of ripeness. ''Yuzu'' fruits, which are very aromatic, typically range between in diameter but can be as large as a regular grapefruit (up to , or larger). Yuzu forms an upright shrub or small tree, which commonly has many large thorns. Leaves are notable for a large, leaf-like Petiole (botany), petiole, resembling those of the related makrut lime and ichang Papeda (citrus), papeda, and are heavily sce ...

Amanatsu
or is a yellow citrus fruit, a cultivar that originated as a mutation of the or . It was discovered in 1935 in Tsukumi, Oita Prefecture, Japan. The original natsu mikan that served as the basis for amanatsu was found in Yamaguchi Prefecture around 1700. Names ''Amanatsu'' means "sweet summer" in Japanese. In Japan, the fruit is known as , but also colloquially the ''amanatsu'', , , & . Description Natsumikan is about the size of grapefruit and oblate in shape. The fruit contains 12 segments and about 30 seeds. The rough textured fruit is easy to peel and is commonly eaten fresh. It is also used for wide variety of products ranging from marmalades to alcoholic beverages. Cultivation Natsumikan is grown commercially in Japan, notably in Yamaguchi, Kumamoto and Ehime prefecture. The city of Hagi is famous for its natsumikans, particularly when used in natsumikan juice and ice cream. Yamaguchi Prefecture takes such pride in their natsumikan industry that the typically ...

Ketone
In organic chemistry, a ketone is an organic compound with the structure , where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' are methyl), with the formula . Many ketones are of great importance in biology and industry. Examples include many sugars (ketoses), many steroids, ''e.g.'', testosterone, and the solvent acetone. Nomenclature and etymology The word ''ketone'' is derived from ''Aketon'', an old German word for ''acetone''. According to the rules of IUPAC nomenclature, ketone names are derived by changing the suffix ''-ane'' of the parent alkane to ''-anone''. Typically, the position of the carbonyl group is denoted by a number, but traditional nonsystematic names are still generally used for the most important ketones, for example acetone and benzophenone. These nonsystematic names are considered retained IUPAC names, although some introdu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carvone
Carvone is a member of a family of chemicals called terpenoids. Carvone is found naturally in many essential oils, but is most abundant in the oils from seeds of caraway (''Carum carvi''), spearmint (''Mentha spicata''), and dill. Uses Food applications Both carvones are used in the food and flavor industry. As the compound most responsible for the flavor of caraway, dill, and spearmint, carvone has been used for millennia in food. Food applications are mainly met by carvone made from limonene. ''R''-(−)-Carvone is also used for air freshening products and, like many essential oils, oils containing carvones are used in aromatherapy and alternative medicine. Agriculture ''S''-(+)-Carvone is also used to prevent premature sprouting of potatoes during storage, being marketed in the Netherlands for this purpose under the name ''Talent''. Insect control ''R''-(−)-Carvone has been approved by the U.S. Environmental Protection Agency for use as a mosquito repellent. Stereoiso ...

Farnesene
The term farnesene refers to a set of six closely related chemical compounds which all are sesquiterpenes. α-Farnesene and β-farnesene are isomers, differing by the location of one double bond. α-Farnesene is 3,7,11-trimethyl-1,3,6,10-dodecatetraene and β-farnesene is 7,11-dimethyl-3-methylene-1,6,10-dodecatriene. The alpha form can exist as four stereoisomers that differ about the geometry of two of its three internal double bonds (the stereoisomers of the third internal double bond are identical). The beta isomer exists as two stereoisomers about the geometry of its central double bond. Two of the α-farnesene stereoisomers are reported to occur in nature. (''E'',''E'')-α-Farnesene is the most common isomer. It is found in the coating of apples, and other fruits, and it is responsible for the characteristic green apple odour. Its oxidation by air forms compounds that are damaging to the fruit. The oxidation products injure cell membranes which eventually causes cell dea ...

Essential Oil
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean required or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, ...

Pomelo
The pomelo ( ; or pummelo, ''Citrus maxima''), also known as a shaddock, is the largest citrus fruit. It is an ancestor of several cultivated citrus species, including the bitter orange and the grapefruit. It is a natural, non-hybrid citrus fruit, native to Southeast Asia. Similar in taste to a sweet grapefruit, the pomelo is commonly eaten and used for festive occasions throughout Southeast and East Asia. As with the grapefruit, phytochemicals in the pomelo have the potential for drug interactions. Description The pomelo tree may be tall, with a trunk, often rather crooked, that is thick, and low-hanging, irregular branches. The petioles (leaf stalks) are distinctly winged. The leaves are alternate, ovate or elliptic in shape and long; they are leathery and dull green above, hairy beneath. The flowers – single or in clusters – are fragrant and yellow-white in color. The fruit is large, in diameter, round or somewhat pear-shaped. Its weight varies by cultivar fr ... [...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 varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate 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 hybridization, which include genetic and morph ...
