Abstract

The effect of the organophosphorus insecticide tetrachlorvinphos (Gardona) has been studied on the mitosis and meiosis of Vicia faba, using the pure insecticide. An aqueous saturated solution of tetrachlorvinphos affected neither mitosis (after seed-soak and root treatment) nor meiosis (after spraying the plants at the flowering stage). The obtained results may be attributed to the low solubility of tetrachlorvinphos. A saturated solution of tetrachlorvinphos in Tween-60: water mixture (1:99) induced a statistically significant percentage of abnormal cells in root-tip meristems after root treatment for 4 h. Chromosome stickiness, disturbed meta- and anaphases and anaphase bridges were observed.

摘要

使用纯有机磷杀虫剂毒死蜱（陶斯松），研究了其对蚕豆有丝分裂和减数分裂的影响。毒死蜱的饱和水溶液对有丝分裂（种子浸泡和根部处理后）和减数分裂（开花期对植株喷雾后）均无影响。所得结果可能归因于毒死蜱的低溶解度。在吐温60与水的混合物（1:99）中，毒死蜱的饱和溶液在根部处理4小时后，根尖分生组织中诱导出具有统计学意义的异常细胞百分比。观察到染色体粘连、中期和后期紊乱以及后期桥。
