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。 Senescence of maize leaves has an important effect on the formation of grain and yield. A large number of studies have shown that leaf senescence is affected by many factors, resulting in huge changes in morphology and physiology and biochemistry, and these changes are inseparable from the gene regulation. This review summarizes the recent researches on maize leaf senescence in China and abroad, including physiological and biochemical characteristics of maize leaf senescence, cultivation techniques and molecular biology of maize leaf senescence, in order to provide reference for the further research on maize leaf senescence.
