Other claims from this paper (10)
- Observation Freezing survival rates were lowest in 4-week-old potato plants.
- Intervention effect Salicylic acid induced freezing tolerance in both potato cultivars.
- Intervention effect Salicylic acid inhibited ascorbate peroxidase activities in both cultivars at all harvest points.
- Intervention effect Salicylic acid inhibited catalase activities only at stage (a), the 4-week-old in vitro stage.
- Intervention effect Salicylic acid induced H2O2 accumulation only in Atlantic at stage (a).
- Intervention effect H2O2 enhanced shoot catalase activities in Atlantic at stages (a) and (b).
- Intervention effect H2O2 treatment induced freezing tolerance in Atlantic.
- Intervention effect In Atlantic, shoot catalase activities after H2O2 treatment were lower than those of the controls following exposure to freezing temperatures.
- Mechanism The authors conclude that SA does not always lead to H2O2 accumulation even though catalase and ascorbate peroxidase activities are decreased by the treatment.
- Mechanism The authors conclude that H2O2 accumulation is not always associated with the induction of freezing tolerance.
