Other claims from this paper (7)
- Intervention effect Root cooling at +1°C induced a decrease of about 2% in relative water content of the leaves.
- Observation The induced deficit disappeared rapidly after return to normal root temperature.
- Intervention effect The treatment produced after-effects on steady rates of water absorption and transpiration in light.
- Observation After-effects were not completely eliminated 24 h after removal of stress.
- Association The magnitude of after-effects varied with leaf water content.
- Mechanism Decreased water flow after stress removal is attributed mainly to increased stomatal resistance rather than root conductivity.
- Mechanism Increased stomatal resistance appears linked to increased membrane permeability rather than to reduced active ion uptake.
