Cytological Effects of Achillea Fragrantissima Extract on Allium cepa and Vicia faba

Abstract

The effect of Achillea extract on mitosis was studied in root tip cells of Allium cepa and Vicia faba. Two types of treatments were carried out, direct and recovery for different hours.
Accumulation of prophases was observed in most of the direct treatments. While after recovery, accumulation of metaphases was noted.
Inhibition of mitotic index appeared clearly in treated A. cepa root cells after direct treatment. While in Vicia the mitotic index was not nearly affected by the direct treatment of the extract.
