- Intervention effect Selenium and mercury cotreatment increased wheat seedling chlorophyll content by 7.6% over mercury alone.
- Intervention effect Selenium and mercury cotreatment increased wheat seedling chlorophyll content by 3.5% over control.
- Intervention effect Cotreatment decreased wheat seedling MDA levels by 38.8% relative to mercury alone.
- Intervention effect Cotreatment yielded wheat seedling MDA levels 20.0% lower than control.
- Intervention effect Selenium above 10 mg?L-1 gradually decreased wheat seedling chlorophyll and raised MDA.
- Intervention effect Selenium at 5-10 mg?L-1 promoted SOD and CAT activity in wheat seedlings, with activity increasing with selenium concentration.
- Intervention effect Mercury and selenium cotreatment increased SOD activity by 21.8% compared with mercury alone.
- Intervention effect Mercury and selenium cotreatment increased CAT activity by 32.8% compared with mercury alone.
- Intervention effect At 15–20 mg?L-1 selenium, SOD and CAT activities trended downward.
