Other claims from this paper (14)
- Intervention effect Heating transiently raised root hydrogen sulfide, peaking 1.5 hours afterward.
- Observation Root H2S returned to the control level after 24 hours.
- Intervention effect Hardening rapidly increased root SOD activity.
- Intervention effect Hardening gradually increased catalase and guaiacol peroxidase activity.
- Observation Antioxidant-enzyme activity changes peaked 24 hours after hardening.
- Intervention effect Hypotaurine and sodium pyruvate eliminated catalase and peroxidase activation.
- Intervention effect Hypotaurine and sodium pyruvate hardly affected SOD activity.
- Intervention effect Damaging heating increased root-cell lipid peroxidation products.
- Intervention effect Damaging heating killed a significant proportion of seedlings.
- Intervention effect Preliminary hardening significantly increased heat resistance.
- Intervention effect Preliminary hardening decreased lipid peroxidation intensity.
- Intervention effect Preliminary hardening decreased seedling death.
- Intervention effect Hypotaurine and sodium pyruvate largely neutralized hardening-induced heat resistance.
- Mechanism Authors infer that hydrogen sulfide signals antioxidant regulation and heat resistance under hardening.
