Abstract: A semi-closed assimilation chamber installation has been used to measure variant growth and development states and net photosynthetic rate (Pn) of plant popular for pot soybean at 3 CO2 concentrations: 700,500,350ppm. Experiment has been shown that height, LAI (leaf area index), dry weight and net p
