摘 要:
叶片衰老是叶片逐渐丧失光合作用并进入细胞死亡的一个复杂的叶片发育过程, 与农作物的产量和品质密切相关。植物生长发育信号和外界环境因素通过多种激素信号途径调节叶片衰老的起始和进程。本文简要综述了八种常见激素在叶片衰老中的研究进展, 并总结了这些激素在叶片衰老调控中的作用方式和机制。关键词:叶片衰老; 植物激素; 作用机制

Abstract:
Leaf senescence is a complex developmental phase that involves both loss of photosynthesis and cell death, and further impacts crop yield and quality. The onset and progression of leaf senescence are regulated by internal development signals and environmental stresses through different hormonal pathways. We review the current progresses of the eight phytohormones regulating leaf senescence and summarize their roles in leaf senescence.Key words: leaf senescence; phytohormone; mechanism
