Mercury at various soil concentrations (10, 100, 250, and 500.10E2 mol per cubic dm had negative effects on young barley plant growth. The growth of roots was inhibited more than the growth of the above-ground parts. Inhibition of these processes correlated with mercury concentration. Bioaccumulation of mercury in the plants correlated with Hg sup(2+) ions in soil. Mercury decreased or increased chlorophyll content,possibly as a defense against Hg sup(2+) concentration. In general it decreased chlorophyll content. Only the concentration of 100 micro mol resulted in an increase of chlorophyll.
