Evaluating Genotoxic Potential of Chromium on Pisum sativum

Abstract

Heavy metal presence in soil is increasing due to anthropogenic activity lead to undesirable genotoxic effect on plants. The purpose of present investigation was to analyze genotoxic potential of chromium on pisum sativum root meristematic cell. Three concentration of chromium 10, 40, 80 ppm were used in the investigation. It was analyzed that with the increase in concentration mitotic index decrease. Control show highest 27 percent mitotic index and chromium 80 ppm show lowest mitotic index 8 percent. It reduce germination percentage by 50% at highest concentration. Chromium induce considerable amount of chromosomal aberration including, stickiness, legards, clumping, bridge, asynchronous division .chromosomal disintegration and loops .stickiness is induced in every stage of cell division.
