Abstract: The experimental study in different CO2 concentration conditions (350×10- 6, 500×10-6, 600×10-6, 700×10-6) for C3 wheat, soybean, Chinese cabbage and C4 maize showed that as CO2 concentrion went up, then p hotosynthetic rate was increased, photosynthetic period of time was extended, bu t light c
