Other claims from this paper (17)
- Intervention effect Under 28 days of drought, net photosynthetic rate declined by 26.6% in CL53.
- Intervention effect Under 28 days of drought, net photosynthetic rate declined by 32.6% in CL40.
- Observation Intercellular CO2 concentration (Ci) remained stable in CL53.
- Mechanism A stable Ci in CL53 indicates superior mesophyll integrity and antioxidant capacity.
- Association CL53 showed rapid Pn recovery after rehydration, in contrast to CL40.
- Observation Drought triggered extensive stomatal closure.
- Observation More than 98% of stomata reopened upon rehydration.
- Observation Total stomatal pore area remained reduced after rehydration.
- Association ABA accumulation was greater in CL40.
- Mechanism ABA accumulation contributes to stomatal closure and Pn suppression in CL40.
- Association CL53 showed faster ABA degradation.
- Mechanism Faster ABA degradation and GA3 recovery in CL53 promote photosynthetic restoration.
- Association ABA was negatively correlated with Pn, Tr and Gs.
- Association ABA was negatively correlated with Ci.
- Association ABA was positively correlated with stomatal limitation (Ls).
- Association Water use efficiency (WUE) showed a parabolic response to ABA, differing by cultivar.
- Observation Photosynthetic inhibition under drought resulted from both stomatal and non-stomatal limitations.
