Abstract
The effect of deoxynivalenol (DON) and T-2 toxin on mitotic index (MI) and relative division rate (RDR) in actively dividing onion (Allium cepa L.) root-tip cells was studied. Both these toxins resulted in decline of mitotic activity which was inversely proportional to the concentrations of these toxins. T-2 was more effective resulting in 59% RDR value at 2.5 ppm whereas DON treated root cells had 78% RDR at the same concentration as compared to respective sets of controls.
