- Intervention effect Nickel significantly reduced SOD, CAT and APX activities in rice leaves.
- Intervention effect Nickel enhanced POD activity in rice leaves.
- Intervention effect Nickel increased H2O2 and MDA content in rice leaves.
- Intervention effect External calcium increased SOD, CAT, APX and POD activities under nickel stress.
- Intervention effect External calcium reduced cell-membrane permeability in stressed leaves.
- Intervention effect At 10 mmol/L Ca2+, antioxidant enzyme activities were higher than at 5 mmol/L under nickel stress.
- Intervention effect At 10 mmol/L Ca2+, H2O2 and MDA contents were lower than at 5 mmol/L under nickel stress.
- Mechanism The authors suggest calcium tolerance operates through oxygen-species scavenging and membrane integrity.
