Cell cycle stage specific application of cypermethrin and carbendazim to assess the genotoxicity in somatic cells of Hordeum vulgare L.

In this study, the genotoxicity of commonly used insecticide cypermethrin and fungicide carbendazim were examined on root meristem cells of Hordeum vulgare L. Cypermethrin and carbendazim were applied with concentrations of 0.05%, 0.1% and 0.5% at different presoaking durations of 7 h, 17 h and 27 h which falls into G(1), S and G(2) phases of cell cycle, respectively. The cytogenetic studies of the root meristem cells of Hordeum vulgare L. showed that S phase of the cell cycle was more sensitive in comparison to other phases of cell cycle.
