摘　　要：综述了水稻叶片早衰对产量的影响及其评价指标,记述了叶片早衰过程中叶绿素、蛋白质含量、一些酶类活性、丙二醛等生理指标的变化,分析了几种外源激素应用于防止叶片早衰的研究进展,并对今后水稻叶片早衰方面的研究提出了一些建议。The effects of early - senescence indexes of rice leaf on yield were reviewed in this paper. The change of physiological indexes in leaf senescence process, including chlorophyll, the content of protein, activities of some enzymes and content of MDA were summarized. Research advances in external phytohormones were analyzed to prevent the rice leaf senescence. Finally some advices on the future study of rice leaf senescence were put forward.
