The Effects of Corelation Between Leaf and Other Organs on Leaf Senescence
器官间关系对叶片衰老的影响

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.
