Description The effects of technical grade hexachlorocyclohexane (tech-HCH) on the germination of different seeds were tested.
Two types of seeds, radish and green gram showed marked reduction in germination percentage and seeding vigour
index. The abnormalities and reduction in germination increased with increasing concentration of tech-HCH. At 100 lg HCH level the germination of radish and green gram seeds was inhibited almost completely on moist filter paper and soil. Protease and amylase activities were reduced in seeds grown in soil spiked with tech-HCH. Bioremediation of
HCH-spiked soils with a HCH-degrading microbial consortium helped in eliminating the toxic effects of tech-HCH
towards seed germination. The degradation of 25 lg tech-HCH g1 soil was complete by 120 h. The seed germination
and the activities of the assayed enzymes, amylase and protease, were same as before or better in bioremediated soils.
