florigen n.【植物;植物學】成花素。adj.-ic

florilegium

Florigen ( flowering hormone ) a hypothetical plant hormone that has been postulated to account for the transfer of the photoperiod stimulus from the leaves to the apex where flowering is induced 成花激素:一種假定的植物激素,該假設用來解釋來自于葉中,在莖端誘導成花的光周期刺激物質的轉運。

The stimulus can be transferred from one plant to another by grafting , but attempts to isolate florigen have so far been unsuccessful 該刺激物可通過嫁接從一個植株轉移到另一植株,但目前還沒有成功分離出成花激素。
