Title

Potato Responds to Salt Stress by Increased Activity of Antioxidant Enzymes

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.
