Other claims from this paper (8)
- Intervention effect Water deficit decreased both enzyme activities, more in ICSV 1063 at -2.3 MPa.
- Intervention effect Rewatering increased both enzyme activities, more significantly in MIGSOR.
- Intervention effect Water stress significantly reduced relative water content in ICSV 1063, less in MIGSOR.
- Intervention effect Relative water content quickly recovered after rehydration.
- Observation At minimal water potential, photosynthesis was completely inhibited and stomata closed.
- Intervention effect MIGSOR photosynthesis recovered better after rehydration but stayed below day-zero values.
- Observation PPDK and PEPC remained active when photosynthesis ceased.
- Mechanism Authors suggest PPDK and PEPC activity may limit carbon dioxide fixation.
