Other claims from this paper (9)
- Observation Salt-induced shoot growth decline was more severe than root decline in both potato cultivars.
- Intervention effect NaCl reduced shoot and root potassium content dose dependently in both potato cultivars.
- Intervention effect NaCl increased sodium content of shoots and roots in both potato cultivars.
- Intervention effect NaCl increased ascorbate peroxidase, catalase and glutathione reductase activities in Kennebec shoots.
- Intervention effect NaCl decreased the corresponding antioxidant enzyme activities in Concord shoots.
- Observation Roots of the two potato cultivars showed similar antioxidant enzyme responses to NaCl.
- Association Antioxidant enzyme activity in Concord shoots declined with increasing NaCl concentration.
- Association Antioxidant enzyme activities in Kennebec shoots and roots of both cultivars lacked a dose dependence.
- Mechanism The authors suggest increased antioxidant enzyme activity contributes to Kennebec salt tolerance.
