Other claims from this paper (13)
- Intervention effect Salt decreased root dry weight only in the sensitive Pérola cultivar.
- Intervention effect Salt mainly hampered root elongation in tolerant Pitiúba.
- Observation Root sodium content reached toxic levels in both cultivars under salt stress.
- Mechanism Root growth inhibition may reflect ionic toxicity rather than salt-induced water deficit.
- Intervention effect Electrolyte leakage increased markedly, mainly in Pérola.
- Intervention effect Lipid peroxidation decreased similarly in both salt-stressed cultivars.
- Intervention effect APX and SOD activities fell under salinity in both cultivars to similar values.
- Association The decline in APX and SOD activities was greater in Pitiúba than its controls.
- Intervention effect CAT activity decreased significantly in Pitiúba.
- Intervention effect CAT activity did not change in Pérola.
- Intervention effect POX activity increased in both cultivars.
- Mechanism The reduced CAT activity in Pitiúba roots appears incompatible with more effective oxidative protection.
- Association Root antioxidant enzyme activities and lipid peroxidation were not associated with differential cowpea salt tolerance.
