Other claims from this paper (6)
- Intervention effect Transpiration increased during high-VPD heatwaves regardless of CO2 or fertiliser.
- Intervention effect Abaxial leaf surface water fluxes increased during heatwaves.
- Association Higher transpiration and water use increased wheat drought vulnerability.
- Association Higher transpiration and water use reduced total ear weight.
- Intervention effect After one hour of darkness during high-VPD heatwaves, stomatal conductance declined only 37–38%.
- Intervention effect Wheat stomata were inhibited from closing under high CO2 and high-VPD heatwaves.
