Abstract

In the present study, effect of Cr and Pb on seedlings growth of S. indicum has been studied under 10, 50 and 100 μM concentration of Cr and Pb. These heavy metal significantly affected all the growth parameters of seedling such as root and shoot length, leaf area, biomass production and root development at all concentrations when compared to control. PKDS-8 variety of Sesame was found to be more susceptible to both the heavy metals but maximum deleterious effect was observed at higher concentrations (50 and 100μM).The seedling growth of sesame was more sensitive to Cr in comparison to Pb. This preliminary information on the initial growth of seedling may help in the screening of the tolerance level of the target plant against two heavy metals for the proper growth and development of the sesame as now a day, this important oil yielding crop has emerged as a leading revenue generation resource of this region.
