Effect of Lead and Cadmium on the Growth Parameters and Protein Content of Coleus blumei Benth and Heavy Metal Extraction Capacity

The study was focused on the effect of heavy metals on the growth parameters of Coleus blumei benth and its remediation capacity. Even the effect of metals on the protein content was measured by Bradford method. High concentration significantly reduced protein content and plant growth. The effect of Lead and Cadmium accumulation on growth was analyzed by the measurement of various parameters like Shoot length Root length protein content. The absorption rate of heavy metal by plants were analyzed by qualitative analysis. Results of qualitative analysis showed presence of heavy metals in leaf, stem, root. Roots showed highest accumulation as compare to stem and leaves. Coleus blumei benth is metal stress tolerant and has phytoextraction capacity of heavy metals from contaminated soil.
