It has been proved that photosynthesis is the physiological basis in crop yield formation, and to some extent, the intensityofphotosynthesis determines the level of crop production.
光合作用是作物产量形成的生理基础，光合作用的强弱一定程度上决定了作物产量的高低。

In this paper, with spinach as a testing material, we studied the effects of DCMU on photosynthesisof plant from the characteristics of DF decay kinetic curve and its total intensity.
本文以菠菜叶片作为实验材料，从DF衰减动力学及其总强度的变化研究了DCMU对植物光合作用的影响。

With the different concentration of DCMU treatment, the intensityof the DF and net photosynthesis rate (Pn) behaved excellent correlation.
