Abstract:The biological effects and cytogenetic damage induced by diesel on root tips cells of Scirpus triqueter explored in this study. The results showed that the root length and weight decreased obviously with diesel concentrations increasing. The mitotic index in root tip cells of seedlings were increased first and then decreased significantly, while the frequencies of micronucleus increased with the diesel concentrations increasing. However, high concentration of diesel restrained the frequencies of micronucleus. So diesel caused biological changes, root tip cells mitotic divisions and the chromosome mutation in root of Scirpus triqueter, which indicated significant genetic toxicity.
