Genotoxic Effect of Hexaconazole on Root Meristem Cells of Triticum aestivum L.

Babu K, Vennila K and Umarajan KM


In vivo cytogenetic assay in Triticum aestivum L. root meristem cells has been carried out to study the effect of triazole fungicide - Hexaconazole on mitotic division, chromosomal aberration and induction of micronuclei. Pre- soaked (12 h) seeds were treated with different concentration of Hexaconazole viz. 6.25, 12.5, 25 & 50 ppm for 6, 12 & 24 h. The treated samples exhibited significant (P<0.05) increases in the frequency of chromosomal aberrations and decrease in mitotic index. These abnormalities were observed in a dose and duration dependent manner. The present study reveals that the Hexaconazole is potential toxic to the plants
