Allium cepa'nın Somatik Hücreleri Üzerine Oxyfluorfen’in Sitotoksik ve Genotoksik Etkileri

In this work, the cytotoxic and genotoxic influences of oxyfluorfen herbicide were surveyed by examining mitotic index, stages, chromosomal anomalies, micronucleus percentage, comet assay parameters on somatic cells Allium cepa. The roots treated with 0.2, 0.4, 0.8 1.6 ppm concentrations 12, 24 36 h. application periods. Mitotic index was noticeably diminished in each group when matched their control, except for 0.2 ppm. percentages stages altered. Oxyfluorfen enhanced drastically aberrant cell ratio at all groups periods contrast to excluding anomalies noted as disturbed prophase, stickiness, C-mitosis, chromatid bridges laggards. detected interphase its percentage determined applied concentrations. Also, employed examine single strand breakages. Almost used increased DNA losses. A positive relationship discovered between occurrence loss.
