Abstract: Abstract: Leaf senescence is the last step of plant development， and it is of great significance to the recycling of nutrition and the formation of seeds. Plant leaf senescence is a complex physiological process which is affected by multi-factors and multi-mechanisms. In this article， we introduced internal and external factors that influence plant leaf senescence.
