Abstract

Effects of various concentrations of essential oils (0, 2.5, 5, 10, 20, 50 and 100 percent) of Zhumeria majdae leaves collected from Sarchahan mountain on mitotic cell division and its stages in root cells of Allium cepa were  studied in this investigation. Results showed that all of essential oil concentrations reduced the number of mitotic cells. The average of mitotic cells in control was 7.5 % and in 100% concentration was zero, and also prophase, metaphase and anaphase phases were reduced. The most of decreament was in prophase stage. There are many terpenes compounds in essential oils of Zhumeria majdae leaves.They are probably a major effective factor in decrease of mitotic cell division in Allium cepa roots.
