摘要
水杨酸(SA)化学名称为邻羟基苯甲酸,已经被证明是一种新型植物激素,是广泛存在于植物体内的重要的内源信号分子。水杨酸不仅能够调节植物的某些生长发育过程,还具有诱导植物提高抗逆性的作用,使植物产生抗逆性,抵抗不良因素造成的伤害。简要综述了水杨酸在高盐、干旱、高温、低温、病虫害等逆境胁迫条件下诱导植物抗逆性的产生及作用机理。
The chemical name of salicylic acid(SA)is o-hydroxybenzoic acid.It has been proven to be a new type of plant hormone and an important endogenous signal molecule that exists widely in plants.Salicylic acid can not only regulate certain growth and development processes of plants,but also has the effect of inducing plants to improve stress resistance,so that plants can develop stress resistance and resist damage caused by unfavorable factors.The production and mechanism of salicylic acid induced plant resistance under stress conditions such as high salinity,drought,high temperature,low temperature,pests and diseases were briefly reviewed.
