%X The effects of NaCl solution on chromosome behavior and sister chromatid exchanges(SCE)of barley were studied.Abnormal chromosome behavior including chromosome fragmentation,micronuclei,anaphase bridges and unequal split was found in root tip cells of Hordeum vulgare seedlings.Mitotic index decreased but SCE frequency increased significantly when barley incubated with NaCl solution.The effects of NaCl solution depended on its concentration and treatment duration.The higher the treated concentration was,the higher the ratio of chromosomal aberration was.The longer the treatment duration was,the higher the degree of the effects was.The results showed that NaCl solution was genotoxic when the concentration was higher and the treated time was longer.
