摘要
盐胁迫是影响水稻生长发育和产量的主要非生物因素之一,外源物质能有效缓解盐对水稻的毒害作用并增加水稻产量。本文主要综述了不同外源物质(生长素、赤霉素、细胞分裂素、脱落酸、乙烯、褪黑素、水杨酸、多胺、油菜素类固醇、茉莉酸类外源生长调节物质以及钙、硅离子类外源物)对盐胁迫下水稻生长的不同调控机理及其缓解效应,并进一步对外源物质在水稻耐盐上的利用与研究工作进行了展望,以期为改善盐渍土环境下水稻的生长发育以及提高产量和品质提供理论依据。
Salt stress is one of the main abiotic factors hindering rice growth,development and grain yield.By the use of exogenous substances,adverse effects can be alleviated and its growth and yield traits can be improved.This work reviews the regulation mechanism and mitigation effect of different exogenous substances(auxin,gibberellin,cytokinin,abscisic acid,ethylene,melatonin,salicylic acid,polyamine,brassinosteroid and jasmonic acid as well as calcium and silicon ionic exogenous substances)on rice salt stress.Finally,the utilization and research work of exogenous substances on salt tolerance of rice is prospected in order to lay a theoretical basis for improving rice growth,yield and quality in saline soil.
