e4“the active oxygen metabolism of T. repens seedlings was destroyed by high amounts of Cu and Cd, the balance of the anti-oxidase system was broken, and the CAT and SOD activities noticeably decreased while POD activity evidently increased”

- Intervention effect Combined Cu and Cd at high concentrations had synergistic, obviously negative effects on seedlings.
- Intervention effect Cu and Cd pollutants made seedlings shorter and smaller than controls.
- Intervention effect Cu and Cd pollutants decreased drastically the fresh/dry weight and soluble protein content of seedlings compared with controls.
- Intervention effect Cu and Cd pollutants increased leaf electric conductivity of seedlings compared with controls.
- Intervention effect Cu and Cd pollutants decreased leaf pigment contents of seedlings compared with controls.
- Intervention effect Chlorophyll a was more sensitive than chlorophyll b to Cu and Cd pollutants.
- Intervention effect Chlorophyll b was more sensitive than carotenoid to Cu and Cd pollutants.
- Intervention effect High amounts of Cu and Cd noticeably decreased CAT and SOD activities in T. repens seedlings.
- Intervention effect Cd had a more noticeable effect on seedling growth than Cu.
- Intervention effect Low concentrations of Cu (less than 500 ppm) and Cd (less than 0.5 ppm) had no obvious effect on seedling growth.
