Abstract:
Taking 6 high-yield soybean cultivars as material，the vertical distribution of pod and leaf area in stem，the physiological parameters of chlorophyll contents，photosynthetic rate(Pn) of pod and leaf in seed-filling period were investigated.Results indicated that the pod-area accounted 19.83%-35.44% of the leaf-area，pod chlorophyll content and true photosynthetic rate accounted 5.67%-8.20%,and 13.32%-55.98%.Heinong 38 had highest ratio of pod-area to leaf-area and leaf true photosynthetic rate，which was 34.85% and 26.4 μmol CO2.m-2.s-1,respectively.For pod true photosynthetic rate，Jiyu 67 was highest of 8.48 μmol CO2.m-2.s-1，and Shidou 2 was the lowest of 2.24 μmol CO2.m-2.s-1The photosynthetic parameters of soybean pod varied greatly among genotypes，and pod photosynthetic traits in seed-filling period had great potential in improving soybean yield.
