摘要：Pollution by heavy metals is one of the important threatening factors in the world. The present study wasintended to analyse the effect of lead (Pb) on seed germination, growth and chlorophyll content of Vignaradiata (L). Wilczek. Germination parameters like germination percentage, radicle and hypocotyl length,vigour index and growth index were studied, and found to be decreased with increasing concentrations.Phytotoxicity level increased at elevated concentrations. At higher concentrations, severe morphologicalsymptoms and reduction in chlorophyll content were observed. However, by treatment with Pseudomonasfluorescens, a plant growth promoting rhizobacterium, a significant increase in all parameters was observed.
