Abstract
The study was conducted on a tropical sculptural herbaceous perennial plant Tradescantia spathacea under greenhouse. This ornamental plant was subjected to different concentrations of heavy metal 40, 80 and 100 mg/kg, with the aim to evaluate biochemical and metal accumulation response of Tradescantia spathacea under enriched mixed treatments of a heavy metal solution containing metals viz. Lead, Cadmium, Chromium and Copper. The exposure time of heavy metals on plants was 30 days. Its biochemical analysis was performed and after harvesting its heavy metal analysis from shoot and root was performed, it was found that treatments were highly significant (p <0.05) under pot trials. Exposure to heavy metal substantially reduced the Chlorophyll a, chlorophyll b, total chlorophyll, carotenoid, and protein at 100 mg/kg. Result showed increment in the proline, phenol, catalase, peroxidase pertaining to 100 mg/kg. Shoot metal uptake potential of Pb (85.10 mg/kg), Cd (53.94 mg/kg), Cr (52.42 mg/kg) and Cu (59.74 mg/kg) and Root metal potential uptake of Pb (307.5 mg/kg) Cd (92.42 mg/kg), Cr (66.74 mg/kg) and Cu (77.59 mg/kg) was observed. The result of this study indicates that Tradescantia spathacea has bioconcentration factor >1 for Pb, Cd, Cr and Cu and Translocation Factor <1. Hence it can be used for phytostabilization of Cr, Cd, Cu, and Pb. It could be used to remediate the heavy metal contaminated soil upto 100 mg/kg.
