Other claims from this paper (7)
- Association The t50 relationship with the steady-state difference was strongest at low leaf-to-air vapour pressure deficits (0.5-1.0 kilopascal) and when dark-adapted leaves were excluded.
- Association The t50 relationship at 400 µmol mol −1 CO2 had R2 = 0.86 in tomato leaves.
- Association The t50 relationship at 600 µmol mol −1 CO2 had R2 = 0.66 in tomato leaves.
- Association The t50 relationship at 800 µmol mol −1 CO2 had R2 = 0.92 in tomato leaves.
- Observation A survey of the literature suggests that the t50 relationship also exists in other tree and herbaceous species.
- Method / resource The t50 relationship is a useful proxy for the rate of photosynthetic induction between any two light intensities, using conventional steady-state light response curves.
- Recommendation The authors provide a guide for best practice for characterizing the t50 relationship in tomato leaves.
