Abstract
The toxicity of trace metals on human health and the environment has attracted considerable attention in recent years. Plants are the main link in the transfer of heavy metals from the contaminated soil to humans. In the present study, effects of different concentrations of chromium (Cr, 50-250 mg/l) was analyzed in medicinal plant Abrus precatorius L. with respect to seed germination, shoot and root growth and their dry weights along with changes in biochemical contents like pigments, protein and total sugar. The study showed that the different concentrations of Cr had an adverse effect on percentage of germination and growth parameters. The results also suggested that at higher concentrations, roots were strongly affected as compared to shoots. Further, when biochemical analysis was carried out it was depicted that the biochemical contents like chlorophyll A and B, carotenoids, protein and total sugar also decreased sequentially as the Cr concentration was increased.
