Other claims from this paper (8)
- Intervention effect Increasing EDTA from 0 to 0.5 mmol L(-1) progressively increased root elongation of Indian mustard under lead exposure.
- Intervention effect Increasing EDTA from 0 to 0.5 mmol L(-1) progressively increased shoot dry matter of Indian mustard under lead exposure.
- Intervention effect Increasing EDTA from 0 to 0.5 mmol L(-1) progressively increased root dry matter of Indian mustard under lead exposure.
- Observation Shoot lead concentration reached 1140 mg kg(-1) dry weight at 0.5 mmol L(-1) Pb plus 0.25 mmol L(-1) EDTA.
- Association Shoot Pb and EDTA concentrations were significantly positively correlated.
- Intervention effect MC root pretreatment increased mustard shoot Pb concentration 14-fold versus no pretreatment.
- Intervention effect hot water root pretreatment increased mustard shoot Pb concentration 15-foldfold versus no pretreatment.
- Recommendation The authors recommend controlled root damage to enhance plant metal uptake and reduce chelate dose in phytoremediation.
