摘要
对不同土壤盐分条件下甜菜叶片的光合作用过程进行了研究．结果表明：在适宜的盐分浓度范围内，甜菜叶片的光合速率高于非盐分处理（对照）；甜菜光合作用的日进程表现出午后单峰特点．另外对气孔变化与甜菜光合作用的关系也进行了初步研究．
Photosynthesis of sugarbeet leaves under different conditions of soil salt is studied. The results show that the photosynthetic rates of sugarbeet leaves under a suitable condition of soil salt is higher than that of the contral. A single peak in the daily course of photosynthetic rate of sugarbeet leaves rises at about pm 14∶00, which is the characteristics of sugarbeet photosynthesis. In addition, the relationship between photosynthesis and stomatal change of sugarbeet leaves is also preliminarily studied.
