Other claims from this paper (4)
- Intervention effect Elevated CO2 reduced March 2000 transpiration per unit leaf area by 37%
- Intervention effect Elevated CO2 reduced October 2000 transpiration per unit leaf area by 49%
- Mechanism Part of the transpiration reduction under elevated CO2 is an immediate, reversible response
- Mechanism An indirect effect of elevated CO2 on transpiration is caused mainly by greater self-shading
