Other claims from this paper (5)
- Method / resource Tissue resistance reduced apparent water potential by 4 to 6% per second of cooling.
- Method / resource A modified dewpoint procedure avoided these errors.
- Intervention effect Irradiance exposure caused large changes in apparent water potential.
- Association Apparent water potential changes correlated with psychrometer zero-offset shifts.
- Method / resource Explicit correction is impossible with the present psychrometer design.
