The ''yuzu'' (''Citrus ichangensis × C. reticulata'', formerly ''C. junos'' Siebold ex. Tanaka; Japanese ユズ, 柚, 柚子 (''yuzu''); 유자 (''yuja'') in Korean; from Chinese 柚子, ''yòuzi'' but sometimes also 香橙 ''(xiāngchéng)'') is a citrus fruit and plant originating in East Asia. It is believed to be a hybrid of sour mandarin and Ichang papeda. The fruit looks somewhat like a grapefruit (though usually much smaller) with an uneven skin, and can be either yellow or green depending on the degree of ripeness. ''Yuzu'' fruits, which are very aromatic, typically range between 5.5 and 7.5 cm in diameter, but can be as large as a grapefruit (up to 10 cm or larger). ==Description== Yuzu forms an upright shrub or small tree, which commonly has many large thorns. Leaves are notable for a large petiole, resembling those of the related kaffir lime and ichang papeda, and are heavily scented. Yuzu closely resemble to sudachi (a Japanese citrus from Tokushima Prefecture) in many regards; they share a similar mandarin-ichang papeda ancestry, though yuzu eventually ripen to an orange colour, and there are subtle differences between the flavours of the fruit. The Yuzu originated and grows wild in central China and Tibet. Confusingly, in modern Chinese, the name 柚子 (yòuzi) refers to the pomelo, while the ''yuzu'' is known as 香橙 (xiāngchéng). It was introduced to Japan and Korea during the Tang Dynasty and it is in these nations that it is cultivated most widely. It is unusual among citrus plants in being relatively frost-hardy, due to its cold-hardy ''C. ichangensis'' ancestry, and can be grown in regions with winters at least as low as -9 °C (15 °F) where more sensitive citrus would not thrive. In Japan, an ornamental version of yuzu called "flower yuzu" is also grown for its flowers rather than its fruit. A sweet variety of yuzu known as the ''yuku'', only present in Japan, became severely endangered during the 1970s and 1980s; a major attempt has been made to revive this varietal in southern Japan. Another variety of yuzu in Japan, with knobby skin is called .〔(photo )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「yuzu」の詳細全文を読む スポンサード リンク
