Abstract

In this study, Tiefeng 31 seedling leaves were sprayed with 1500 mg L-1 KHCO 3 and NaHCO 3 , respectively, and determined the photosynthetic rate, soluble sugar, photosynthetic pigment and other physiological indexes to explore the effect of K + , Na + and HCO 3 ˉ on soybean seedlings photosynthesis. The results showed that: compared with water spraying control, K + , Na + and HCO 3 ˉ improved soybean seedlings photosynthetic rate, the content of soluble sugar, chlorophyll a, chlorophyll b, and the ratio of chlorophyll b in total chlorophyll; promoted soybean seedlings photosynthesis by providing more assimilatory power to dark reactions carbon fixation; and enhanced the activities of ATP enzyme, photo phosphorylation, and PEPC. In addition, HCO 3 -played a more important role in promoting chlorophyll b synthesis and improving photosynthetic rate. NaHCO 3 significantly increased the content of Rubisco. For other physiological indexes but the content of Rubisco, the promotion of K + is more than Na + .
