Japanese Citrus
A number of citrus fruits are grown in or strongly associated with Japan. Many of these fruits are of Chinese origin, but have been modified or specially bred for cultivation in Japan. Japanese taxonomy Japan usually follows the botanical names of the taxonomy from Tyôzaburô Tanaka, often referred to as the "Tanaka system", giving for each cultivar a separate name no matter if it is pure or a hybrid of two or more species or varieties. While elsewhere it is more popular to classify the genus citrus into species, and further into varieties, and then into cultivars or hybrid. Such a system was created by Walter Tennyson Swingle from Florida and is called the "Swingle system". The different approaches of the two systems lead to partially-overlapping or nested 'species', for example, ''Citrus unshiu'' and ''Citrus tangerina'' (Tanaka) versus ''Citrus reticulata'' (Swingle). Likewise, common terms, like "mikan", do not always align with these taxonomic groups. Japanese citrus (pa ...

Citrus Reticulata
The mandarin orange (''Citrus reticulata''), also known as the mandarin or mandarine, is a small citrus tree fruit. Treated as a distinct species of orange, it is usually eaten plain or in fruit salads. Tangerines are a group of orange-coloured citrus fruit consisting of hybrids of mandarin orange with some pomelo contribution. Mandarins are smaller and oblate, unlike the spherical common oranges (which are a mandarin–pomelo hybrid). The taste is considered sweeter and stronger than the common orange. A ripe mandarin is firm to slightly soft, heavy for its size, and pebbly-skinned. The peel is thin, loose, with little white mesocarp, so they are usually easier to peel and to split into segments. Hybrids usually have these traits to a lesser degree. The mandarin is tender and is damaged easily by cold. It can be grown in tropical and subtropical areas. According to genetic studies, the mandarin was one of the original citrus species; through breeding or natural hybridization ...

Ponkan
Ponkan (); ''Citrus poonensis''; "Chinese Honey Orange") is a high-yield sweet ''Citrus'' cultivar with large fruits in the size of an orange. It is a citrus hybrid ( mandarin × pomelo), though it was once thought to be a pure mandarin. Description "Pon" harkens to the "Poona orange" of original stockand "kan" means citrus fruit. The fruit is very sweet, round in shape and about wide in size. Trees are heavy bearing every other year, and sometimes the limbs break due to the heavy yields. Growers resort to propping the limbs up with sticks at times, though if the limb bends gradually down and grows in that position it will do better in future years. Trees can be propagated by seed, as they breed true, or grafted onto other rootstocks, trifoliate orange being the most popular. Andrew Willis of Apopka, Florida, promoted the Ponkan heavily in the early 1900s. Ponkan is also noted for having a loose rind that is very easy to peel. Cultivation Ponkans are widely grown in the Unite ...

Kiyomi
(''Citrus unshiu'' × '' sinensis'') is a Japanese citrus fruit that is a hybrid of a ''Miyagawa Wase'' mikan and an orange. The new breed was the first tangor created in Japan in 1949. It was named Kiyomi after the temple and the lagoon near its experiment station in Shizuoka city and registered as "Tangor Nōrin No.1" in 1979. Kiyomi are sweet. Sugar content is normally 11–12°  Bx and reaches even 13 °Bx if conditions are met. Citric acid content is around 1%. It has no seeds. The time of ripening is mid to late March. The flavor is similar to that of a ''mikan'', while the aroma is similar to that of an orange. Kiyomi is a monogerm, so it is often used as a parent citrus to create new hybrids such as dekopon is a seedless and sweet variety of satsuma orange. It is a hybrid between Kiyomi and ponkan (Nakano no.3), developed in Japan in 1972. Originally a brand name, "Dekopon" has become a genericized trademark and it is used to refer to all bran .... ...

Dekopon
is a seedless and sweet variety of satsuma orange. It is a hybrid between Kiyomi and ponkan (Nakano no.3), developed in Japan in 1972. Originally a brand name, "Dekopon" has become a genericized trademark and it is used to refer to all brands of the fruit; the generic name is . Dekopon is distinctive due to its sweet taste, large size and the large protruding bump on the top of the fruit. Names The name is most likely a portmanteau between the word ''deko'' (凸, デコ; meaning ''convex'') as a reference to its bump, and the ''pon'' in ponkan (ポンカン; one of the fruits that it is derived from) to create "dekopon" (デコポン). There were many market names for dekopon during the time the name was a trademark of the product from Kumamoto, Kumamoto, Kumamoto. For instance, ''himepon'' was the market name for the fruits originating from Ehime prefecture. The ones grown in Hiroshima prefecture were marketed as ''hiropon''. After an agreement whereby anyone could use the ...

Daidai
The daidai (Japanese: 橙, 臭 橙; Chinese: 酸 橙; Korean: 광귤, ''gwanggyul''), is an Asian variety of bitter orange. The daidai originated in the Himalayas. It spread to the Yangtze valley region and later to Japan. The colour of the fruit loses yellowish hue and becomes greener in the spring. The native Japanese word for the color orange, or ''daidai-iro'', is derived from the name of this fruit. Uses There are two main cultivars, and , and the latter bears smaller fruits than the former in Japan. The fruit is very bitter, and not usually eaten, but its dried peel is used in Kampo (the Japanese adaptation of Chinese medicine). The dry peels of young fruits are called ''kijitsu'' ( 枳 実), and used as a stomachic and expectorant as well as a laxative. Peel of ripe daidai is called , and is used as a fragrant stomachic and expectorant. Cultural aspect The name ''daidai'', originally meaning "several generations" (and written as or ), came from the fruit staying ...

Buddhas Hand 1
In Buddhism, Buddha (; Pali, Sanskrit: 𑀩𑀼𑀤𑁆𑀥, बुद्ध), "awakened one", is a title for those who are awake, and have attained nirvana and Buddhahood through their own efforts and insight, without a teacher to point out the dharma (Sanskrit 𑀥𑀭𑁆𑀫; Pali ''dhamma''; "right way of living"). The title is most commonly used for Gautama Buddha, the founder of Buddhism, who is often simply known as "the Buddha". Buddhahood ( sa, 𑀩𑀼𑀤𑁆𑀥𑀢𑁆𑀯, buddhatva; pi, buddhatta or ; ) is the condition and rank of a buddha "awakened one". This highest spiritual state of being is also termed ''sammā-sambodhi'' (skt. samyaksaṃbodhi 'full complete awakening'). The title is also used for other beings who have achieved ''bodhi'' (awakening) and ''moksha'' (release from craving), such as the other human Buddhas who achieved enlightenment before Gautama, the five celestial Buddhas worshiped primarily in Mahayana, and the bodhisattva named Mai ...

Buddha's Hand
''Citrus medica'' var. ''sarcodactylis'', or the fingered citron, is an unusually-shaped citron variety whose fruit is segmented into finger-like sections, resembling those seen on representations of the Buddha. It is called Buddha's hand in many languages including English, Chinese, Japanese, Korean, Vietnamese, and French. The different cultivars and variations of this citron variety form a gradient from "open-hand" types with outward-splayed segments to "closed-hand" types, in which the fingers are kept together. There are also half-fingered fruits, in which the basal side is united and the apical side fingered. The origin of this kind of citron is commonly traced back to South or East Asia, probably northeastern India or China, where most domesticated citrus fruits originate. Description ''Citrus medica'' var. ''sarcodactylis'' is, like any other citron variety, a shrub or small tree with long, irregular branches covered in thorns. Its large, oblong leaves are pale green ...

Pomelo Fruit
The pomelo ( ), ''Citrus maxima'', is the largest citrus fruit from the family Rutaceae and the principal ancestor of 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 consumed and used for festive occasions throughout Southeast Asia. As with the grapefruit, phytochemicals in the pomelo have the potential for drug interactions. Etymology and common names According to the Oxford English Dictionary, the etymology of the word "pomelo" is uncertain. It may be derived from Dutch ''pompelmoes''. Its botanical name, ''Citrus maxima'', means "the biggest citrus". In English, the word "pomelo" (also spelled pummelo, pumelo, pomello, pommelo) has become the more common name, although "pomelo" has historically been used for grapefruit. After introduction to Barbados by 'Captain Shaddock' of the East India Company (apparently Philip Chaddock, who visited the island in the late 1640s), t ...

Banpeiyu
Banpeiyu ( ja, 晩白柚) is a cultivar of pomelo which produces extremely large fruits. A banpeiyu fruit became the world's heaviest pomelo when it was presented by Seiji Sonoda from Japan for the Guinness World Record at the Banpeiyu Competition in Yatsushiro, Kumamoto, Japan on December 25, 2014. This specimen weighed 4.8597 kg (10 lb 11.3 oz) with a circumference of 83.5 cm (32.8 in). The fruit of the banpeiyu is very popular in Japan for eating fresh, due to its blend of mild acidity and pleasant sweetness. It is also used in the production of fruit jelly. Origin and names Banpeiyu is mostly known today as a Japanese citrus and is ranked as the most popular pomelo cultivar in Japan, producing high quality fruits in the hottest regions of the country. Nevertheless, it is assumed to be of unknown, possibly Malayan origin, and arrived in Japan via Taiwan where it was introduced in 1920, and is sometimes referred to as a Taiwan pomelo. It also has many ot ...

Spheroid
A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry. If the ellipse is rotated about its major axis, the result is a ''prolate spheroid'', elongated like a rugby ball. The American football is similar but has a pointier end than a spheroid could. If the ellipse is rotated about its minor axis, the result is an ''oblate spheroid'', flattened like a lentil or a plain M&M. If the generating ellipse is a circle, the result is a sphere. Due to the combined effects of gravity and rotation, the figure of the Earth (and of all planets) is not quite a sphere, but instead is slightly flattened in the direction of its axis of rotation. For that reason, in cartography and geodesy the Earth is often approximated by an oblate spheroid, known as the reference ellipsoid, instead of a sph ...
