| 摘 要： | 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。

| Abstract: | The plant senescence is an important period of plant development, which is 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 of coordinated changes during the plant senescence. Some environmental and internal factors influence the plant senescence. The principal hypotheses that are used for explaining the plant senescence include the exhausted nutrient hypothesis and the death hormone hypothesis. |
