摘　　要：高等植物的性别表达不稳定。研究发现,植物个体在发育过程中环境条件的改变可能会改变原定程序的表达,从而引起植物性别分化方向或群体性别比例的变化,甚至使性别分化逆转。文中概述了矿质营养、气体、湿度、光照、温度和创伤等多个方面的环境因子与生长素、赤霉素、脱落酸、乙烯和细胞分裂素5类植物激素在植物性别表达中的作用,对其应用前景和研究中存在的不足进行了探讨,以期为今后的研究提供参考。Sex expression of higher plants is unstable. Research showed that, during the development of plant individuals, environment changes possibly lead to the change in original sex expression, thus causing the change in the sex differentiation direction or the rate of population sex, or even the reverse in sex differentiation. This paper reviewed the roles of a number of environmental factors sueh as mineral nutrition, gas, humidity, light, temperature and trauma as well as plant hormones such as auxin, gibberallin, abscisie acid, ethylene and cytokinin in plant sex expression, and also discussed the prospects and the shortcomings of this study and its application. The conclusion and analysis on the influencing factors for sex expression of plants were expected to provide references for the research in the future.
