Abstract:
The effect of Amiprophos Methyl (APM) on cell mitotis of root meristems of Triticum aestivum was investigated at different concentrations (1~4 μmol/L) and treatment times (4~6 h). The results indicated that mitotic index could be obviously increased when root tip was treated at 1~4 μmol/L APM for 5h. The rise of mitotic index had no linear relation with the increase of c(APM). APM could induce micro-nucleate in interphase cells, and made chromosome polymerized and spindle function disturbed in metaphase cells.The disturbance in spindle function could cause the unequal cell division and multipolar cell division.
