<p>The aim of this study was the evaluation of acute<strong> </strong>genotoxic<strong> </strong>effect of effluent water of thermo-power plant by means of <em>Tradescantia </em>root tips micronucleus test (MN), mitotic index and cell aberrations.   <em>Tradescantia</em>, was experimentally treated (for 24 h), with effluent water of thermo-power plant in different dilution ratios (negative control – distilled water; primary untreated effluent water and 1:1; 1:2; 1:3; 1:4; 1:5; 1:6 and 1:7 respectively). Number of aberrant cells, and frequency of micronuclei (MN), in meristematic root tip cells of treated plants (<em>Tradescantia</em>), were significantly increased (P&lt;0.001; P&lt;0.001 respectively), while the mitotic index in all treated plants was progressively decreased in comparison to the negative control. The results of present study indicate that Tradescantia root-tip micronucleus assay with direct exposure of intact plants is an appropriate method which enables to detect genotoxic effects of effluent waters.</p>
