Abstract

The effect of water extract from Teucrium pilosum on mitoisis of Allium cepa was studied.The extract had anti-mitotic effect on Allium cepa roots. Accumulation of prophases on the expense of the other phases was clear after direct treatment. While they nearly regain their normal percentage after 24h recovery.The induced types of abnormalities were, spindle disturbance, stickiness, C-mitosis, lagging (or surpassing) chromosome, bridges, polyploidy and breaks.
