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 aspects：the 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．
