摘　　要：玉米叶片衰老对子粒形成和产量有着重要的影响。大量研究表明,叶片衰老受众多因素影响,造成形态及生理生化的巨大变化,而这些变化均离不开基因的调控作用。本文综述了近年来国内外有关玉米叶片衰老的研究结果,主要包括玉米叶片衰老的生理生化和栽培技术研究及有关玉米叶片衰老的分子生物学研究,以期能为玉米叶片衰老的进一步研究提供参考。Leaf senescence can profoundly influence grain filling and the yield of maize. Lots of studies indicat-ed that leaf senescence is influenced by multiple factors, resulting in remarkable changes in morphology and physiol-ogy of maize, which are also associated tightly with the regulation of the relevant genes. In this article,recent advanc-es in maize leaf senescence were reviewed, including physiology, biochemistry and cultivation techniques of maizeleaf senescence, and molecular biology of maize leaf senescence research. It is expected to provide information forfurther research in maize leaf senescence.
