Title

Other claims from this paper (7)
- Intervention effect Chilling induced salicylic acid accumulation, especially conjugated SA, in leaves and roots of both rice cultivars.
- Intervention effect After SA administration, SA accumulated concentration-dependently in the roots of both cultivars, with only a slight increase in leaves.
- Observation Conjugated SA accounted for most of the SA increase after SA administration.
- Intervention effect SA treatment did not protect rice seedlings from chilling injury at any concentration in either cultivar.
- Intervention effect Pre-treatment with SA decreased the chilling tolerance of the rice cultivars.
- Intervention effect SA pre-treatment increased electrolyte leakage and lipid peroxidation under chilling.
- Intervention effect Most antioxidant enzyme activities decreased or stayed unchanged in leaves and roots of SA pre-treated seedlings after chilling.
