Other claims from this paper (7)
- Observation At high water availability, gas exchange rates were similar in controls and resprouts.
- Observation At moderate soil dryness, resprout gas exchange rates remained unchanged.
- Observation Resprouts had higher midday and predawn leaf water potentials at moderate soil dryness.
- Observation Under severe drought, gas exchange declined less in resprouts than controls.
- Observation Under severe drought, resprouts maintained photosystem II integrity.
- Mechanism Photosynthesis was down-regulated in both plant types as reduced CO2 availability resulted from high stomatal limitation.
- Observation Resprouts had lower non-stomatal limitations than controls, with greater carboxylation velocity and ribulose-1,5-bisphosphate regeneration capacity.
