摘要： 本文通过对植物衰老和动植物中编程性细胞死亡(PCD)的研究，阐述了植物衰老中PCD存在的依据，澄清了植物衰老和PCD的关系，提出了植物衰老中可能的PCD发生途径，为调控植物衰老的遗传操作提供依据。

Abstract: This review discusses the evidences of the involvement of programmed cell death (PCD) in plant senescence and the relation between PCD and plant senescence, and suggests a molecular mechanism unique to plant senescence, which may provide the basis for genetic engineering of plant senescence.
