Other claims from this paper (8)
- Intervention effect Drought reduced CO2 assimilation, transpiration and stomatal conductance from day seven.
- Intervention effect Intercellular CO2 rose from day seven and peaked at most severe stress.
- Observation Carboxylation efficiency was low at maximum stress and remained below unstressed values after ten days of rewatering.
- Observation After five days of rewatering, both leaf water potentials matched control plants.
- Observation After five days of rewatering, assimilation, transpiration and conductance still differed from controls.
- Association Leaf ABA tended to rise as afternoon leaf water potential fell.
- Association Stomatal conductance fell as afternoon leaf water potential fell.
- Observation ABA accumulated and stomata closed when afternoon leaf water potential was below −1 MPa.
