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.
在本研究中，检测了常用杀虫剂氯氰菊酯和杀菌剂多菌灵对大麦根分生组织细胞的遗传毒性。氯氰菊酯和多菌灵分别以0.05%、0.1%和0.5%的浓度在7小时、17小时和27小时的不同预浸泡时间下施用，这三个时间分别对应细胞周期的G(1)、S和G(2)期。对大麦根分生组织细胞的细胞遗传学研究表明，与细胞周期的其他阶段相比，细胞周期的S期更敏感。
