Other claims from this paper (16)
- Observation Wheat photosynthesis acclimated more to drought than to growth temperature.
- Intervention effect Drought lowered the optimum temperature of wheat photosynthesis.
- Intervention effect Drought lowered wheat light‐saturated net photosynthesis at the photosynthetic optimum.
- Intervention effect Drought lowered wheat stomatal conductance at the photosynthetic optimum.
- Intervention effect Drought lowered wheat mesophyll conductance at the photosynthetic optimum.
- Intervention effect Drought lowered wheat maximum rate of electron transport ( J max ) at the photosynthetic optimum.
- Intervention effect Drought lowered wheat maximum rate of carboxylation by Rubisco ( V cmax ) at the photosynthetic optimum.
- Observation Optimum temperature for wheat V cmax reached 40°C when well watered.
- Observation Optimum temperature for wheat V cmax was 24–34°C under drought.
- Association The decrease in wheat photosynthesis under drought varied with growth temperature.
- Mechanism Photorespiration partly explained the temperature response of wheat photosynthetic quantum yield under drought.
- Mechanism Alternative electron transport explained more of the wheat quantum yield response under drought.
- Mechanism Changed wheat leaf nitrogen did not fully explain the biochemical parameter changes.
- Observation Wheat diffusional and biochemical photosynthesis parameters acclimated little to growth temperature.
- Observation Wheat photosynthetic parameters acclimated considerably to drought and combined drought and growth temperature.
- Method / resource Common models strongly overestimated wheat leaf photosynthesis under variable temperature and drought.
