Abstract

Allium cepa bulbs were grown in pure tap water (Group I) and in five concentrations (10-1M to 10-5M) alone (Group II) and all five concentration of cadmium chloride as in group II but each contained myrobalan in it at 0.10 mg/ml (Group III). Parameters of study were mean root length, mitotic index, abnormal mitosis and chromosomal aberrations and morphology of root tips. Cadmium chloride exposure significantly inhibited root growth, declined mitotic index, caused abnormal mitosis and aberrations (Group II). In the presence of myrobalan (Group III) cadmium-induced mitodepression, abnormal mitosis and aberrations could be appreciably prevented. No morphological changes in the root tips of any group could be noticed. Probable protective role of myrobalan is discussed.
