Abstract The effects of various cadmium (Cd) concentrations (10, 50 and 100 μM) on root growth, cell division and micronuclei formation in root tip cells of Allium cepa var. agrogarum L. were investigated to better understand the processes of Cd-induced apoptosis. The results indicated that 10 μM of Cd had an obviously passive influence on root growth during the 24 h treatment, and that the influence was even more serious with increasing Cd concentrations and duration of treatments. The mitotic index decreased with increasing Cd concentration and duration of treatments. Cadmium induced c-mitosis, chromosome bridges, chromosome stickiness and micronuclei. The frequency… More >
