Rice Growth, Yield and Photosynthetic Responses to Elevated Atmospheric Carbon Dioxide Concentration and Drought

J. T. Baker; L. H. Allen Journal of Crop Improvement 2005. doi:10.1300/j411v13n01_02

Other claims from this paper (7)

Intervention effect Elevated CO2 increased rice growth, grain yield and canopy photosynthesis.
Intervention effect Elevated CO2 reduced evapotranspiration by about 10% in rice.
Intervention effect Under drought stress cycles, elevated CO2 allowed rice photosynthesis to continue one to two days longer than under ambient CO2.
Observation Rice canopy photosynthesis saturated with respect to CO2 near 500 μmol mol−1.
Intervention effect Long-term CO2 enrichment of 350 and 700 μmol mol−1 showed little evidence of photosynthetic acclimation or down-regulation in rice.
Intervention effect Daytime CO2 enrichment resulted in higher canopy dark respiration than ambient grown controls.
Intervention effect Rising chamber CO2 at 28°C directly and reversibly inhibited canopy dark respiration rate in rice.
