The effects of pesticides (Endosulfan, Dieldrin, Aldrin) on cell division and chromosomal morphology of Vicia faba L. were studied. The results showed that the pesticides are mitode-pressive in higher concentrations and mitopromotor in lower concentrations and induced a variety of chromosomal abnormalities such as stickiness, fragments, chromatid separation, disturbed metaphase, C-mitosis, laggards, precocious movement and late separation where lagging chromosomes were predominant. The concentration of 500 ppm or above, for all the pesticides used in the present study showed pronounced toxic effect. In remaining treatments, although the milotic index was improved but less than that of absolute controls.
研究了农药（硫丹、狄氏剂、艾氏剂）对蚕豆细胞分裂和染色体形态的影响。结果表明，这些农药在高浓度下具有抑制有丝分裂的作用，在低浓度下具有促进有丝分裂的作用，并诱导了多种染色体异常，如粘连、片段化、染色单体分离、中期紊乱、C-有丝分裂、落后染色体、早熟移动和后期分离，其中落后染色体占主导。本研究中使用的所有农药，500 ppm及以上的浓度显示出明显的毒性作用。在其余处理中，虽然有丝分裂指数有所提高，但低于绝对对照。
