C₃植物叶片酶对氮添加的响应

Response of C₃ Plants Leaf Enzymes to Nitrogen Addition

目前大部分对植物氮营养和光合作用之间影响的研究表明,氮添加会引起叶片氮含量增加,使植物的净光合速率升高,过量的氮素水平则会降低光合速率。但是对叶片酶和氮添加的作用机制的研究不足。因此,本综述旨在总结氮添加对叶片酶的影响,叶片酶对光合作用影响的生理机制,以便为以后研究氮–叶片酶–光合作用相互作用的生理机制提供思路,引发思考。

At present, most of the studies on the effects of nitrogen nutrition and photosynthesis in plants show that nitrogen addition can increase the nitrogen content in leaves and increase the net pho-tosynthetic rate of plants, but the excessive nitrogen level can decrease the photosynthetic rate. However, the mechanism of leaf enzyme and nitrogen addition is not well studied. Therefore, the purpose of this review is to summarize the effects of nitrogen addition on leaf enzymes and the physiological mechanism of leaf enzymes on photosynthesis, so as to provide ideas for the future study of the physiological mechanism of nitrogen-leaf enzyme-photosynthesis interaction.
