Study of Mitotic Activity and Chromosomal Behaviour in Root Meristem of Allium cepa L. Treated with Magnesium Sulphate

Abstract

The mitotic activity and chromosomal behaviour was observed in four different concentrations of magnesium sulphate at four different duration of treatment using Allium cepa as a biological system. Mito-inhibitory effect of the compound was observed in higher concentration. The compound was capable of producing various chromosomal abnormalities indicating the cytostatic and clastogenic properties of magnesium sulphate. Key words: Allium cepa, magnesium sulphate, mitotic index, phase indices.doi: 10.3126/eco.v15i0.1947 ECOPRINT 15: 83-88, 2008
