- Observation Sunflower accumulated cadmium most in roots, up to 820 μg g−1 dry matter.
- Intervention effect Increasing cadmium supply increased lipid peroxidation and superoxide content.
- Intervention effect Under Cd stress, superoxide dismutase and catalase activities declined more in roots than leaves.
- Intervention effect Under Cd stress, peroxidase activity increased in leaves.
- Intervention effect Under Cd stress, root peroxidase activity decreased.
- Observation Leaf Cd thresholds for 10% and 33% sunflower growth reduction were 14 and 72 μg g−1.
- Observation Root Cd thresholds for 10% and 33% sunflower growth reduction were 65 and 250 μg g−1.
