The results were as follows:The first, there were significantly differences percent between 0.6μg/mlgroups and other three groups (0.2μg/ml groups, 0.4μg/ml groups and 0.8μg/mlgroups) in 2 hour groups; and there were significantly differences between0.4μg/ml groups and other three groups in 4 hour groups; and there weresignificantly differences between 0.6μg/ml groups and other three groups in 6hour groups; and there were significantly differences between 0.4μg/ml groupsand other three groups in 8 hour groups on the metaphases (P＜0.05), in theexperiment of the effect on the mouse 4- cell embryo stage single blastomere ofcolchicine with different concentrations and duration, by x~2 statistical analysis.

实验结果如下：1、在确定秋水仙素不同处理浓度和时间对小鼠4-细胞期胚胎单卵裂球中期分裂相数影响的实验中，经统计分析，阻断培养2小时组中0.6μg／ml浓度组与其他三组差异显著(0.2μg／ml组、0.4μg／ml组和0.8μg／ml组)；阻断培养4小时组中0.4μg／ml浓度组与其他三组差异显著；阻断培养6小时组中0.6μg／ml浓度组与其他三组差异显著；阻断培养8小时组中0.4μg／ml浓度组与其他三组差异显著(P＜0.05)。
