Özet

In this study, the genotoxic effects of the insecticide cypermethrin on the root meristem cells of sunflowers (Helianthus annuus L.) were investigated. The roots were treated with 10- 25- 50- and 100-ppm concentrations of cypermethrin for 6, 12 and 24 h. The mitotic index and mitotic abnormalities were determined in both control and test groups. The cypermethrin showed a marked mitodepressive action on mitosis. The types of mitotic abnormalities included disturbed metaphase, c-mitosis, stickiness, laggards and chromatid bridges. A pronounced toxic effect was observed at the 50-ppm concentration. Cypermethrin may have genotoxic effects on sunflowers.
