Other claims from this paper (4)
- Mechanism Leaf-scale normalized photosynthetic biomass water productivity was proportional to ambient CO2.
- Observation Experimental evidence supported the leaf-scale proportionality in several C3 and one C4 crop.
- Method / resource The paper provided two procedures to normalize differences in evaporative demand.
- Method / resource A CO2 normalization procedure derived at leaf scale also applied at canopy scale.
