Sorgo (English spelling)

Japanese: ソルゴー（英語表記）sorgo

An annual grass of the grass family cultivated for its stems and leaves as feed or for extracting sweet juice from the stems. It is considered to be a variety of sorghum. Sorghum cultivated for feed is classified into three types: grain sorghum, dual-purpose sorghum, and sorghum-type sorghum. Among these, sorghum-type sorghum has a height of 2.4m or more, a thick stem, and is juicy with sweet juice, and there are many mid- to late-ripening varieties. Originally, sorghum was the name given to a variety of this group that had a particularly high sugar content and was differentiated to be used for making molasses and syrup. In Japan, it is called sweet sorghum or rozoku (reed millet), and in America, it is often called sweet sorghum.

茎葉を飼料とするために，または茎から甘汁を採るために栽培されるイネ科の一年草。モロコシの1変種とされる。モロコシ(ソルガム)のうち，飼料用に栽培されるものは，子実型ソルガム(穀実用モロコシ)，兼用型ソルガム，ソルゴー型ソルガムの3者に分類されるが，その中のソルゴー型ソルガムは草丈が2.4m以上で，茎は太く，多汁質で汁は甘みがあり，中生（なかて）～晩生（おくて）の品種が多い。ソルゴーは本来この品種群の中で，とくに糖分含量が多く，糖みつ，シロップなどの製造にも利用される方向に分化した変種に与えられた名称で，それを日本ではサトウモロコシ，ロゾク(蘆粟)などと呼んでおり，アメリカでもスイートソルガムsweet sorghumを指すことが多い。
