dc.description.abstractThe present study evaluates biomas yield, pigment concentrations, biochemical constituents, and heavy metal accumulation in Brassica juncea L. grown under different concentrations (100, 200, 400, 600, and 800 mg kg1 of soil) of zinc (Zn), lead (Pb), and cadmium (Cd). Plant growth, pigment concentrations, and biochemical parameters were evaluated at a 15-day interval, while plant biomass yield and metal accumulation were determined at maturity. The result showed that low Zn concentrations (100 - 400) mg kg1 increased biomass yield, chlorophyll production, and biochemical contents. Higher concentrations considerably decreased growth, pigment production, and biochemical parameters. Though both Pb and Cd caused decline in growth, biomass yield, carbohydrate, protein, and proline contents, Cd effect was most detrimental at high concentrations. Proline content increased at lower metal concentrations but decreased with higher concentrations. Cadmium was most accumulated in the plant, followed by Pb and the least in Zn and the root system accumulated more metal than the shoot system. The study observed that higher concentrations of heavy metal negatively affected biomass, biochemical content, with higher accumulation predominantly in the root. B. juncea may, therefore, be used as a model plant in studying remediation of heavy metal in contaminated soil.
