Genotoxic evaluations of Allium cepa L. using different concentrations of synthesized butenolide

The roles that fire smoke play in the release of dormancy, germination and seedling growth has been previously examined in different studies. More than 100 compounds were identified in smoke and some of those are known to have physiological effects on plants. In this study, we tested genotoxicity of synthesized butenolide using concentrations of 0, 25, 50, 100, 250, 500 and 1000 ppm. Both, low and high concentrations appeared chromosomal aberrations of meristematic cells of Allium cepa L. The bioassay test showed that physiological and clastogenic abnormalities, such as sticky metaphase and anaphase bridges, were found. There were decreases in means of mitotic index at different concentrations.
