Abstract:
Photosynthesis is an important factor that determines soybean yield.At present，the research on soybeans photosynthetic characteristic mainly concentrates on its relationship with yield.But the coupling effect of water and phosphorus on photosynthetic tratis of different P efficiency genotypic soybean is less documented.Therefore，pot experiments were conducted in 2007 year，with P high efficient soybean Heihe 27，P middle efficient soybean Heinong 43 and P low efficient soybean Heihe 29 as materials，to determine the influence of water and P coupling on physio-biochemical characters of different genotypic soybeans.Two P（applied P and without P）and four water（100%，70%，50% and 30% of the maximum field water holding capability）treatments were designed and photosynthetic rate(Pn)，transpiration rate(Tr)，stomatal conductance（Cs)，intercellular CO2 concentration（Ci）and stomatal limitation(Ls)，the leaf chlorophyll content，leaf area were determined at pod filling stage.The results showed as follows：Under P deficiency and drought，Pn，Tr，Cs and Ls were gradually decreased，but Ci was enhanced，which suggested that the decreased photosynthetic rate might be controlled by non-stomatal limitation.P deficiency and drought reduced leaf area，decreased content of Chl and reduced photosynthetic rate，with low-P efficiency>mid-P efficiency>high-P efficiency.Compared with low-P efficient soybean,high-P efficient soybean showed higher CO2 assimilation and water use efficiency under drought stress.
