agsci-1224	Kong, Xiao; Liu, Zhen; Fu, Weiguo	Effects of Different Soil Moisture Contents on Photosynthesis of Lettuce	2023	7	.pdf	application/pdf	4294	237	46	The qP and NPQ of lettuce under different soil moisture content are shown in Figure 3, and with the decrease of soil moisture content, qP showed a downward trend, increased slightly under B treatment, and then gradually decreased. The results of this study showed that with the decrease of soil moisture content, the transpiration rate, stomatal conductance, net photosynthetic rate and intercellular CO2 concentration of lettuce all showed a downward trend, indicating that the gradual decrease of the net photosynthetic rate of lettuce under drought stress conditions was mainly caused by stomatal restriction, which was consistent with the effect of different soil moisture content on the photosynthetic physiology of lettuce in Pei Yun et al (Pei et al. 2015).	cache/agsci-1224.pdf	txt/agsci-1224.txt
