- Intervention effect Low zinc increased rape SOD activity.
- Intervention effect Low zinc increased rape chlorophyll content.
- Intervention effect At low zinc concentration, superoxide production and membrane permeability showed no marked change.
- Intervention effect Higher zinc concentrations produced shorter and smaller rape fronds.
- Intervention effect Higher zinc concentrations drastically reduced leaf pigments.
- Intervention effect Higher zinc concentrations drastically reduced SOD activity.
- Observation Pigment sensitivity to zinc stress ranked chlorophyll a above combined chlorophyll a+b above chlorophyll b.
- Intervention effect Higher zinc increased membrane penetration and electric conductivity.
- Observation The authors report destruction of rape activated oxygen metabolism under zinc stress.
- Observation The authors report a rape zinc tolerance limit of 1000 mg·kg -1.
