Other claims from this paper (16)
- Observation Under normal conditions SA mainly occurred in conjugated form.
- Observation Under chilling, tomato leaves had high SA levels.
- Intervention effect Free SA accumulated after foliar SA treatment.
- Association SA accumulation magnitude increased with applied SA concentration.
- Observation Chilling enhanced antioxidant capacity but did not alleviate oxidative injury.
- Observation Chilling oxidative injury was not alleviated despite higher antioxidant capacity.
- Intervention effect A 0.5 mmol/L SA pretreatment alleviated chilling oxidative injury.
- Intervention effect SA pretreatment decreased electrolyte leakage in tomato leaves.
- Intervention effect SA pretreatment decreased MDA in tomato leaves.
- Intervention effect SA pretreatment increased H2 O2 in tomato leaves.
- Intervention effect SA pretreatment increased CAT in tomato leaves.
- Intervention effect SA pretreatment increased POD in tomato leaves.
- Intervention effect SA pretreatment increased APX in tomato leaves.
- Intervention effect SA pretreatment increased GR in tomato leaves.
- Observation Ascorbate and glutathione redox ratios remained stable under chilling after SA pretreatment.
- Mechanism The authors speculate that exogenous SA raises endogenous SA, which induces H2 O2 accumulation and antioxidant capacity.
