%0 Journal Article %T Study of Mitotic Activity and Chromosomal Behaviour in Root Meristem of Allium cepa L. Treated with Magnesium Sulphate %A Prabhakar Bhatta %A S. R. Sakya %J Ecoprint: An International Journal of Ecology %P 83-88 %D 2008 %R 10.3126/eco.v15i0.1947 %X 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 %K Allium cepa %K magnesium sulphate %K mitotic index %K phase indices %U http://www.nepjol.info/index.php/ECO/article/view/1947
