Other claims from this paper (6)
- Observation Ecotypes differed significantly in stomatal conductance, predawn leaf water potential, and relative leaf water content.
- Intervention effect Drought stress significantly increased endogenous H2O2 and lipid peroxidation.
- Intervention effect Moderate and severe drought significantly increased five antioxidant and lipid-associated enzyme activities depending on time.
- Observation Constitutive enzyme activities were higher in inland than coastal ecotypes.
- Observation Canonical discriminant analysis distinguished inland from coastal ecotypes by Ψpd, gs, polyphenol oxidase, superoxide dismutase and malonyldialdehyde.
- Observation Inland ecotypes appeared more drought tolerant than coastal ecotypes.
