Effect of CO2 application on the growth and quality of Tomato

It is well known that CO2 concentration is low in green houses during day time and this cause low rate of photosynthesis in crops. It was believed that CO2 application was meaningless because windows are usually open in green houses during summer. However, this study showed that it was possible to increase rate of photosynthesis to increase CO2 concentration up to those of outside. We are studying how to apply CO2 concentration efficiently.
