- Intervention effect Drought retarded wheat seedling growth by 26.5%.
- Intervention effect UV-B radiation retarded wheat seedling growth by 29.1%.
- Intervention effect The combined stress retarded wheat seedling growth by 55.9%.
- Association Shoot fresh weight was negatively correlated with H2O2 content in wheat seedlings (R2 = 0.9251).
- Association Fresh weight was negatively correlated with TBARS content in wheat seedlings (R2 = 0.9005).
- Association H2O2 content was positively correlated with TBARS content in wheat seedlings (R2 = 0.9007).
- Intervention effect Drought increased the activities of superoxide dismutase, guaiacol peroxidase and ascorbate peroxidase in wheat seedlings.
- Intervention effect UV-B increased the activities of superoxide dismutase, guaiacol peroxidase and ascorbate peroxidase in wheat seedlings.
- Intervention effect The combination of stresses increased the activities of superoxide dismutase, guaiacol peroxidase and ascorbate peroxidase in wheat seedlings.
- Intervention effect Under the combined stress, catalase activity decreased compared with the control in wheat seedlings.
- Intervention effect The combination of drought and UV-B caused more severe damage to wheat seedlings than the stress factors applied separately.
- Mechanism Sodium nitroprusside may enhance seedling growth by decreasing H2O2 accumulation and lipid peroxidation.
- Intervention effect Sodium nitroprusside treatment decreased the proline content of wheat seedlings.
- Observation Wheat seedlings showed an increase in H2O2 content and lipid peroxidation degree, indicating oxidative damage.
