Effects of Different Soil Moisture Contents on Photosynthesis of Lettuce
Keywords:
lettuce, soil moisture gradients, photosynthesis, chlorophyll fluorescence
Abstract
In order to explore the photosynthetic physiological response characteristics of lettuce under different soil moisture conditions, the photosynthetic indexes and chlorophyll fluorescence parameters of lettuce under different soil moisture gradients were determined by pot water control experiment. The results showed that with the decrease of soil moisture content, Pn, Tr, Gs, Ci, Fv/Fm, ΦPSII and qP of lettuce leaves all showed a downward trend, while NPQ increased with the decrease of soil moisture content. Among them, the water holding capacity in the field was 55~60%, and the net photosynthetic rate of lettuce was the highest, indicating that mild drought promoted photosynthesis of lettuce.
