Abstract

Rice has been used as staple food for people in various nations. As CO2 is one of the limiting factors in photosynthesis, adding this gas can increase photosynthesis, increasing rice seedlings` growth. Concentration of eCO2 treatment was 600 to 800 μmol mol-1, ambient CO2 (aCO2) was 410 μmol mol-1 to 415 μmol mol-1 and controlled at field conditions. The results demonstrated that the leaf properties of rice seedlings, for instance, leaf length, leaf number per plant, and leaf area, were increased by 9.20%, 10.28%, and 25.67%, respectively, in eCO2 compared to control. Similarly, the general growth properties such as seedling length and seedling dry weight were increased by 18.25 and 34.21% respectively, under eCO2 compared to the control.
