Mitotic index and frequencies of each mitotic phase were calculated for 10,000 cells. Values for particular treatment (in columns, mean ± SE) followed by different small letters are significantly different at the 0.05 level, N = 10 (LSD test). The bold values represent the important differences between treatments and the water control.
