摘要: 大麦幼苗生长在含NaCl的介质中[c(NaCl)=0, 0.05, 0.10, 0.15, 0.20, 0.25mol/L],其根尖细胞有丝分裂指数下降,各NaCl处理组的微核率均有不同程度地增加,并诱发产生了如染色体断片、后期染色体桥及"不均等分裂"等异常分裂。诱发微核及异常分裂细胞的比率与NaCl浓度和作用时间呈正相关,浓度提高或作用时间延长则微核千分率与异常分裂细胞的比率增高。

关键词: 大麦, NaCl, 有丝分裂指数, 微核, 异常分裂

Abstract: Incubated in NaCl solution with different concentration [c(NaCl)=0, 0. 05, 0.10, 0.15, 0.20, 0.25mol/L], Hordeum vulgare seedlings mitosis decreased but micronuclei frequency increased, what is more, Abnormal division including chromosome fragmentation, anaphase bridges and unequal split was found in the root tip cells. The effect of NaCl depended on the concentration and duration time of NaCl breeding. The higher the concentration is, the stronger the effect is. The longer the treated time is, the more the effect is.

Key words: Hordeum vulgare, NaCl, Mitotic index, Micro nuclei, Abnormal mitosis
