Other claims from this paper (8)
- Intervention effect Cadmium significantly reduced shoot and root fresh and dry weights, shoot height, root length and leaf area, with severity increasing with concentration and exposure time.
- Intervention effect Cadmium reduced total chlorophyll content.
- Association The chlorophyll a to b ratio tended to decrease with increasing cadmium concentration.
- Intervention effect Total carotenoid content increased at 10 µM cadmium.
- Intervention effect Cadmium significantly altered elemental status.
- Intervention effect Cadmium increased lipid peroxidation and electrolyte leakage with exposure time.
- Intervention effect Cadmium stimulated antioxidant enzyme activities.
- Association Cadmium treatment was associated with altered ascorbate and glutathione levels and larger DHA and GSH pools.
