摘要(Abstract):

目的:报道大蒜根尖细胞有丝分裂中的异常现象。方法:常规染色体压片法。结果:用矿泉水培养的3批不同大蒜根尖有丝分裂相中均出现了滞后染色体、染色体断片、染色体桥、多极化等染色体畸变现象。结论:大蒜根尖细胞有丝分裂中存在染色体异常现象,是遗传学实验中观察染色体变异的好材料。
Objective: To report a rare phenomena of abnormal mitosis in root tip cells of Allium sativum L.Methods: Traditional chromosome tabletting technique was adopted.Results: Abnormal mitosis was repeatedly observed in 3 batches of A.sativum root immersed in mineral water.Lagging chromosomes,chromosome fragments,chromosomal bridge,and multipolarity were the main phenomena.Conclusion: The results shows that abnormal mitosis might commonly occur in garlic root tip cells.Thus,garlic can be used as good material for the study of abnormal chromosomes.
