Abstract:
Diurnal variation of photosynthetic rate was determined for three different source soybean cultivars by using LI-6400 portable photosynthesis system at flowering and grain filling in the field condition.The correlation between photosynthetic rate and its affecting factors of Cond，Ci，Tr，T.L，CO2R，RH_R，PAR and VpdL were analyzed.The results indicated that limiting factors of net photosynthetic rate were different for three soybean cultivars in different time of a day at flowering and grain filling.Net photosynthetic rate of leaf was positively correlated with Cond，PAR and Tr,but negatively correlated with Ci and VpdL in most time of a day.
