Rice carbon balance under elevated co2

WebbThe CO 2 concentrations were maintained at 160, 250, 330, 500, 660 and 900μmol mol ‐1 air. Photosynthesis increased with increasing growth CO 2 concentrations up to 500u.mol moP1, but levelled off at higher CO 2 values. Specific leaf area also increased significantly with increasing CO 2. Webb20 jan. 2024 · • These results show that the increase in rice biomass by elevated [CO2] results more from the increase in carbon gain at early rather than later stages of growth.
