CYTOGENETIC EFFECTS OF MERCURY CHLORIDE ON THE ROOT TIP CELLS OF ALLIUM CEPA L.

D. BANERJEE, P. BANDHYOPADHYAY AND U. C. SARKAR

Abstract

The cytological effects of mercury chloride on the root tip cells of Allium cepa L were studied. Onions were treated with 25, 50, 75 & 100 ppm of mercury chloride solution for 96 hours, after which both macroscopic (root length) and microscopic (Mitotic Index, Somatic chromosomal anomalies) parameters were observed. The results indicate significant variation in both types of parameters in onions exposed to test solution in comparison to control (tap water). The effects were dose dependent and more anomalies were observed at higher concentrations. Both Mitotic Index and root length response shows significant variation in treated groups in contrast to control groups. Chromosomal anomalies observed included lagging, chromosome bridges and sticky chromatin.
