Other claims from this paper (13)
- Intervention effect Elevated CO2 reduced grain protein concentration of wheat by about 10–15% relative to ambient CO2
- Intervention effect Elevated CO2 reduced grain protein concentration of barley by about 10–15% relative to ambient CO2
- Intervention effect Elevated CO2 reduced potato tuber protein concentration by 14%
- Intervention effect Elevated CO2 reduced soybean protein concentration by 1.4%, a statistically significant but much smaller reduction
- Association The CO2 effect on wheat grain protein was smaller under high soil N than under low soil N
- Association Ozone increased the reduction of potato tuber protein concentration at high than at low ozone concentrations
- Association Elevated CO2 increased soybean protein concentration grown at high ozone concentrations
- Association Open-top chambers gave a larger CO2 effect on soybean protein than other experimental facilities
- Association Open-top chambers gave a larger CO2 effect on wheat protein than other experimental facilities
- Association Plants rooted in pots in open-top chambers showed a greater CO2 effect on wheat protein than plants in the ground
- Association Plants rooted in pots in open-top chambers showed a greater CO2 effect on soybean protein than plants in the ground
- Association Wheat grain protein measured in whole grains showed a greater CO2 effect than when measured in flour
- Association Increasing CO2 concentrations of the 21st century are likely to decrease protein concentration of food crops
