摘要/Abstract

摘要： 利用外源GA3和乙烯利处理黄瓜(Cucumis sativus L.)植株，使性别表达雄性化或雌性化的同时，其内源乙烯的释放量、ACC，GA_1-3和脱落酸的含量，以及乙烯形成酶活性均发生了变化。外源GA₃雄性化处理，使内源GA_1-3含量和GA_1-3/脱落酸值增加，乙烯释放量和ACC含量降低。乙烯利雌性化处理的作用则相反。外源的GA₃和乙烯利对内源ACC水平的影响可能是其对黄瓜性别表达作用的生理学原因。

Abstract: After the induction toward maleness or femaleness of cucumber (Cucumis sativus L.) plant with exogenous GA₃ or ethrel treatments, the endogenous levels of ethylene, ACC, GA_1-3, ABA and EFE activity all changed. As the induction toward maleness with GA₃, the endogenous level of GA_1-3 and GA_1-3/ABA increased while the levels of ACC and ABA decreased. The effects of induction toward femaleness with ethrel were just the opposite. The effects ofexogenous of GA₃ or ethrel on the levels of ACC seem to be the physiological cause of sex shift of cucumber plant.

Key words: cucumber, sex expression, ACC, EFE, endogenous hormone
