Other claims from this paper (12)
- Intervention effect Cadmium and arsenic treatment decreased germination percentage, germination index and vigour index of Phaseolus aureus.
- Intervention effect The inhibition by cadmium and arsenic in Phaseolus aureus was dose dependent, greater at higher metal doses.
- Intervention effect Increasing cadmium and arsenic concentrations reduced phenolic content, catalase and FRAP activity of Phaseolus aureus seedlings compared with control.
- Intervention effect Arsenic showed relatively strong toxicity compared with cadmium in Phaseolus aureus.
- Intervention effect Zinc treatment significantly increased phenolic content, catalase and FRAP activity at low heavy metal concentrations.
- Intervention effect Heavy metal stress enhanced free proline and metal chelating activity in Phaseolus aureus.
- Association Growth amelioration by zinc under metal toxicity was associated with a further enhanced level of free proline.
- Association Zinc supplementation under metal toxicity was associated with improved metal chelating activity.
- Intervention effect Zinc supplementation improved seedling growth of Phaseolus aureus under metal toxicity at 25 and 50 ppm.
- Intervention effect Zinc partially restored seedling growth of Phaseolus aureus at low heavy metal concentrations (25 and 50 ppm).
- Intervention effect Zinc reduced oxidative stress in Phaseolus aureus seedlings at low heavy metal concentrations during seed development.
- Intervention effect At higher heavy metal concentration, zinc did not restore growth or biochemical parameters of Phaseolus aureus.
