Other claims from this paper (8)
- Observation All three heavy metals were toxic to sunflower.
- Observation The toxicity order for primary root elongation was Cd2+ > Cu2+ > Zn2+ (as written).
- Intervention effect Heavy metal stress significantly decreased seedling growth and chlorophyll content of sunflower.
- Intervention effect Heavy metal stress increased the H2O2 level in sunflower seedlings.
- Intervention effect Activities of antioxidative enzymes (SOD and CAT) increased rapidly and then decreased during heavy metal stresses.
- Intervention effect Heavy metal treatments significantly induced accumulation of proline and GSH in sunflower seedlings.
- Intervention effect Cd2+ and Zn2+ stresses induced higher proline accumulation than Cu2+ stress.
- Intervention effect Cu2+ stress resulted in higher GSH level in seedlings than Cd2+ and Zn2+ stresses.
