- Intervention effect Elevated CO2 increased rice biomass by 22% at 37/29 °C.
- Intervention effect At 29/21 °C elevated CO2 increased grain yield by about 50%.
- Observation At 37/29 °C rice grain yield was almost zero.
- Observation At 37/29 °C filled spikelets were below 1%.
- Observation IAC 165 had the largest relative biomass increase among cultivars.
- Observation IAC 165 had the largest relative grain yield increase among cultivars.
- Observation Cultivar responses to CO2 and temperature ranged from 10 to 250%.
- Recommendation The authors conclude that available rice lines could maximize productivity with increasing CO2.
