Abstract

Present investigation on studies of growth character and its accumulation in different parts of Tulsi under various concentration of some heavy metals (Lead and Cadmium), done at Department of Dravyagunna, Faculty of Ayurveda, Institute of Medical science during the year of 2007.The graded levels of these two metals Cd (0, 20, 50, 100 and 200 ppm) and Pb (0, 50, 100, 250, and 500 ppm) applied after the germination of Tulsi. The plant exhibited a decline in growth, chlorophyll content and carotenoids with increasing levels of Pb and Cd., more accumulation of Pb and Cd was observed in roots than shoots in 0. tenuifolium L.
