The Limiting Carbon Dioxide Concentration for Photosynthesis


MANY reports1–5 indicate that plants in a closed system will reduce the concentration of carbon dioxide in the air to a minimum value between 50 and 100 p.p.m. Gabrielsen2 postulates “there exists a threshold value for carbon dioxide in photosynthesis, which for elder leaves is about 0.0090 volume per cent. Below the threshold no assimilation takes place. Thus it seems that only about two-thirds of the atmospheric carbon dioxide is available for photosynthesis”.
