乙烯利影响植物抗旱性研究进展

摘要

Ethephon (2-chloroethyl phosphonic acid,an ethylene-releasing compound) is a plant growth regulator with various systemic properties.It is widely used on wheat,coffee,tobacco,cotton,and rice in order to help fruit to mature more quickly.Various effects of ethephon treatment on plants have been published.This article focused on reviewing the effects of foliar ethephon application on plant drought tolerance.To date,either promotion or inhibition of drought tolerance by ethephon treatment was reported.The effect of ethephon treatment on plant drought response was dependent on many factors,such as the concentrations of ethephon solution,plant species and cultivars,plant developmental stages,and treatment methods.In addition,the possible mechanisms of ethephon treatment affecting plant drought tolerance were discussed.%从喷施和浸种2个方面综述了乙烯利对植物抗旱性的影响,从处理方式、浓度、植物品种、植物生长发育阶段等多个角度阐述了乙烯利影响植物抗旱性的研究进展和动态.此外,综合国内外当前的研究结果,从乙烯、ABA、抗氧化系统和渗透调节物质变化方面综述了乙烯利调节植物抗旱性的作用机制,并对未来的研究方向和发展趋势进行了探讨.
