Abstract:: This study investigated the effects of planting density on photosynthetic capacity of Glycine gracilis. A field experiment was conducted using a split-plot design under five planting densities (18×104 plants·ha-1,S1; 20×10⁴ plants·ha^-1, S2; 22×10⁴ plants·ha^-1,S3; 24×10⁴ plants·ha^-1, S4; 26×10⁴ plants·ha^-1, S5) with Tongnong 15 as material. The result showed that the plant height and lodging rate showed a gradually rising trend along with the density increasing. Fresh weight of root and the amount of root nodules per plant showed a firstly increasing and then decreasing trend with the density increasing, they reached the maximum with S3 treatment. Leaf area index (LAI)were improved along with the density increasing during the period from V4 to R4,while decreased with the density increasing at R6 period.Dry matter, SPAD, seeds number, effective pods per plant and 100-seed weight showed a gradually reduced trend with the increasing density .The net photosynthetic rate (Pn),transpiration rate (Tr) and stomatal conductance (Gs) were decreased with the increasing density in the V4-R6 period,but they were improved with the density increasing in the R7 period.The differences in the net photosynthetic rate (Pn) and transpiration rate (Tr) between S4 and S1,S2,S3 treatments were extremely significant (P＜0.01),the differences in the stomatal conductance (Gs) was significant (P＜0.05). Intercellular CO2 concentration (Ci) was increased with the density increasing．Treatment S3 had the highest yield of 2 908.99 kg·ha^-1 ,which was 7.5%, 3.6%, 9.9% and 21.8% more than S1，S2，S4 and S5 treatments, respectively. The difference in the yield between S3 and S2 was significant (P＜0.05)，and the differences between S3 and S1, S4, S5 treatments were extremely significant (P＜0.01)．The results could provide scientific and reasonable theory basis for the production practice of the plant population of Glycine gracilis．
