摘　　要：引发技术是促进棉花种子萌发、幼苗生长与抗逆性的重要手段。总结了近年来,种子引发在提高棉花耐旱性、耐寒性、耐盐性与抗病性等抗逆性以及促进棉花产量方面的应用效果,并从形态、生理以及分子角度分析归纳了不同引发技术对棉种的作用机制,最后对棉种引发的发展进行了讨论与展望。Seed priming is an important method to promote seed germination,seedling growth,and stress resistance of cotton.This paper summarized the application effect of seed priming on the improvement of drought tolerance,cold tolerance,salt tolerance,and disease tolerance of cotton and the promotion of yield in recent years.And the action mechanisms of different priming technologies to cotton were concluded from the aspects of cotton form,physiology,and molecule.Finally,the development of cotton seed priming was discussed and prospected.
