Phytoextraction of Lead Using a Hedge Plant [Alternanthera bettzickiana (Regel) G. Nicholson]: Physiological and Biochemical Alterations through Bioresource Management

Phytoremediation is a cost-effective and environmentally friendly approach that can be used for the remediation of metals in polluted soil. This study hedge plant–calico (Alternanthera bettzickiana (Regel) G. Nicholson) to determine role citric acid lead (Pb) phytoremediation by exposing it different concentrations Pb (0, 200, 500, 1000 mg kg−1) as well combination with concentration 250, 500 µM). The analysis variance was applied on results significant effects independent variables dependent using SPSS (ver10). According results, maximum measured upper parts plant. An increase dry weight biomass, plant growth parameters, photosynthetic contents observed application (200 soil while reduced experienced at higher (1000 kg−1). antioxidant enzymatic activities like superoxide dismutase (SOD) peroxidase (POD) were enhanced under lower (200, kg−1), whereas reduction occurred greater metal There usual electrolyte leakage (EL) EL increased We concluded this plant, A. Bettzickiana, has ability remediate soils aided application.
