摘　　要：水稻(Oryza sativa L.)作为重要的粮食作物,是全球一半以上人口的主食.叶片衰老是植物叶片发育过程中的最终阶段,是在长期自然进化过程中形成的适应性机制.水稻叶片衰老的进程直接影响着水稻的产量和品质,因此,水稻叶片衰老调控机制的研究对保障或提高作物产量具有重要意义.叶片衰老的进程受到各种外部和内部因素的调控,其中植物激素在调控叶片衰老过程中发挥重要的作用,不同种类激素对叶片衰老进程具有促进或延缓作用.通过查阅国内外相关文献,并分析、归纳后,综述了近年来激素与水稻叶片衰老调控机制的研究进展,以期为深入剖析激素在水稻叶片衰老调控中的作用机制奠定理论基础,同时为水稻稳产高产育种提供相关参考.Rice(Oryza sativa L.),as an important staple food crop,is the main food source for over half of the global population.Leaf senescence is the final stage in the plant leaf development process,and is an adaptive mechanism formed during long-term natural evolution.The process of rice leaf senescence directly affects the yield and quality of rice,therefore,research on the regulation mechanism of rice leaf senescence is of great significance for ensuring or increasing crop yield.The process of leaf senescence is regulated by various external and internal factors,among which plant hormones play an important role in regulating the process of leaf senescence,with different types of hormones having either promoting or delaying effects on the senescence process.By consulting relevant domestic and international literature,analyzing and summarizing,recent research progress on the regulation mechanism of hormones in rice leaf senescence was reviewed,aimed to lay a theoretical foundation for a deeper understanding of the role of hormones in the regulation of rice leaf senescence,and to provide relevant references for breeding high-yielding and stable rice varieties.
