• Abstract: The plan t senescence is an important period of plant development, whichis a programmed process that is subjected to gene regulation. The cell structure, cell function, metabolism and gene expression of the plant go through a series ofcoordinated changes during the plan t senescence. Some environmental and internal factors influence the plan t senescence. The principal hypotheses that are used for enplaning the plant senescence include the exhausted nutrient hypothesis an d the death hormone hypothesis. 衰老是植物发育的一个重要组成部分，是受基因调控的程序性过程。在衰老过程中，植物细胞在细胞结构、细胞功能、新陈代谢和基因表达等方面经历一系列的协调变化，一些环境因素和内在因素影响着植物的衰老。解释植物衰老的学说主要有营养耗尽假说和衰老激素假说。
