摘要: 叶片衰老是整个植株生理特性的敏感表现,受根系、茎、生殖器官和其他叶片等器官的影响。器官间关系影响叶片衰老可能是通过竞争体内营养、水分等物质、竞争环境因子、源库关系、激素等信息系统调节等机制实现的。从整株水平上加强叶片衰老的生理机制和控制技术研究,将为生产上控制衰老、减少叶片异常衰老造成的产量和品质损失提供有效的技术途径。

Abstract: leaf senescence is the significant physiological reflection of the whole plant and is affected by roots, stem, reproductive organs and other leaves. The other organs affect leaf senescence through compacting nutrient substance, water and environmental factors, source sink relationship and signal systems such as plant hormones. It is advanced that leaf senescence should be studied further and regulated more effective on level of whole plant to avoid or reduce the loss on yield and quality caused by abnormal senescence.
