Title
Water loss from leaf mesophyll stripped of the epidermis

Other claims from this paper (8)
- Method / resource Relative evaporation below one inadequately marks the onset of mesophyll regulation.
- Observation At RH below 0.950, daily cycles were suppressed.
- Observation After initial RE near 1.2, RE declined toward zero.
- Observation In water supplied leaf pieces, daily cycles persisted to RH 0.850.
- Observation At RH 0.850, maximal RE was about 2.
- Observation Field leaf transpiration from one surface fell in the same range.
- Recommendation Authors propose maximum RE for each deficit as the threshold for mesophyll regulation.
- Mechanism Authors suggest cell wall water status regulates RE decline below one at low RH.
