The jackfruit (''Artocarpus heterophyllus''), also known as jack tree, jakfruit, or sometimes simply jack or jak is a species of tree in the mulberry and fig family (Moraceae). It is native to parts of South and Southeast Asia, and is believed to have originated in the southwestern rain forests of India, in present-day Goa, Kerala, Odisha, Tamil Nadu, Sri Lanka〔(【引用サイトリンク】title=Jackfruit Paradise )〕 coastal Karnataka, and Maharashtra. The jackfruit tree is well suited to tropical lowlands, and its fruit is the largest tree-borne fruit, reaching as much as in weight, in length, and in diameter. The jackfruit tree is a widely cultivated and popular food item throughout the tropical regions of the world. Jackfruit is the national fruit of Bangladesh, by name Kathal (কাঁঠাল) in Bengali language. The Jackfruit tree can produce about 100 to 200 fruits in a year. ==Etymology== The word "jackfruit" comes from Portuguese ''jaca'', which in turn, is derived from the Malayalam language term, ''chakka'' (Malayalam ''chakka pazham'' : ചക്കപ്പഴം). When the Portuguese arrived in India at Kozhikode (Calicut) on the Malabar Coast (Kerala) in 1498, the Malayalam name ''chakka'' was recorded by Hendrik van Rheede (1678–1703) in the ''Hortus Malabaricus'', vol. iii in Latin. Henry Yule translated the book in Jordanus Catalani's (f. 1321–1330) ''Mirabilia descripta: the wonders of the East''. The common English name "jackfruit" was used by the physician and naturalist Garcia de Orta in his 1563 book ''Colóquios dos simples e drogas da India''.〔''Oxford English Dictionary'', Second Edition, 1989, online edition〕〔Anon. (2000) (The American Heritage Dictionary of the English Language: Fourth Edition. )〕 Centuries later, botanist Ralph Randles Stewart suggested it was named after William Jack (1795–1822), a Scottish botanist who worked for the East India Company in Bengal, Sumatra, and Malaysia. 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「Jackfruit」の詳細全文を読む スポンサード リンク
