STUDY THE EFFECT OF EXTRACTUM ALOES FLUIDUM ON THE MITOTIC ACTIVITY OF CELLS USING THE ALLIUM TEST

The evaluation of the cytogenetic action of aloe extract liquid (Еxtractum Аloes fluidum) in a concentration range of 250−4000 mg/l in meristem cells of onion roots (Allium cepa L.) was carried out. The dynamics of onion root growth and mitotic activity index were taken into account. Analysis of preparations of A. сepa root cells after exposure to aloe extracts of different concentrations with respect to negative (distilled water) and positive (dioxidine 100 mg/l) control showed statistically relible (p<0.05) inverse dependence of root growth and mitotic index on concentration.
