Other claims from this paper (10)
- Intervention effect Mercury stress decreased wheat seedling SPAD and inhibited SOD and CAT activities.
- Intervention effect Mercury stress increased wheat seedling MDA and proline content.
- Intervention effect Adding 10 mg L-1 Zn increased SPAD by 5.6% under mercury stress.
- Intervention effect Adding 10 mg L-1 Zn decreased MDA by 32.4% under mercury stress.
- Intervention effect At Zn concentrations above 10 mg L-1, SPAD gradually decreased.
- Intervention effect At Zn concentrations above 10 mg L-1, MDA increased significantly.
- Intervention effect Lower Zn concentrations promoted SOD and CAT activity.
- Intervention effect At 20 mg L-1 Zn, SOD activity increased 103.3% relative to mercury alone.
- Intervention effect At 20 mg L-1 Zn, CAT activity increased 71.0% relative to mercury alone.
- Intervention effect Added Zn lowered proline content relative to mercury alone and control.
