| Summary: | The cytological effects of two carbarnate insecticides, methomyl and oxarnyl, were analysed in the meristematic cells of the root tips of Vicia faba. The former induced chromosomal alterations which were analyzed in anaphase cells as chromatid aberrations(single fragments and bridges), chromosomes with inactivated centromeres, isochromosomes and disturbances in the mitotic Gindle as multipolar anaphases, as well as micronuclei scored in interphase cells. Only the chromatid aberration frequenciesaugmented with the increment of concentration of methomyl. In relation to its action upon cell division, it was observed that methomyl had an inhibitory effect dernonstrated by the low mitotic index. On the other hand, oxarnyl at the concentrations tested did not induce clastogenic alterations neither produce any effect on the mitotic index. |
