| 摘 要： | 多胺是广泛存在于植物体内具有调控作用的一类生理活性物质，其代谢变化与高等植物的生长、发育和抗逆性关系密切。本文从逆境胁迫下多胺代谢情况、外源多胺及其抑制剂对植物抗逆性的影响、突变体与转基因在研究多胺与抗逆性上的应用三个方面对多胺与逆境之间的关系进行介绍，并对逆境下多胺如何影响其他生理活动（作为渗透调节物质，信号分子，调节离子通道）进行了系统性地阐述，最后对其研究前景进行了展望。

| Abstract: | Polyamine is a kind of physiological active substance with regulatory effect，and widely exists in plants．Its metabolic changes are closely related to the growth and development of higher plant．In this paper the relationship between polyamine and adversity are introduced．The paper was carried out in the following 3 aspectsthe polyamine metabolism in adversity stress，the effect of exogenous polyamines and their inhibitors on plant stress resistance，the application of mutant and transgene in studying the polyamine and stress resistance．Besides，this paper systematically expounded how polyamine affected other physiological activities（as osmoregulation substance，signal molecules，the regulation of ion channels）in adversity stress．Before ending，the paper prospected the future in studying． |
