The Present investigation was performed to assess the response of black gram genotypes under chromium stress. Different concentrations of chromium Viz., 0, 5,10,25,50,100 and 200mg l-1 were prepared and used for the germination studies. The germination Parameters Such as rate of germination, germination index, vigour index, tolerance index, root and shoot length, and dry matter production were recorded under chromium stress. There was a significant variation observed among the genotypes in the performance of seed germination characteristics. 5mgl-1 chromium concentration showed a positive effect over the seed germination characteristics of black gram genotypes. However the higher concentration of chromium showed the inhibitory effect over the germination characteristics of black gram.
