摘要: 显微镜观察结果显示,在中度盐胁迫(2%NaCl)下生长发育的大麦根尖细胞出现三个特点:1.根冠淀粉体显著减少;2.基本分生组织区出现淀粉体;3.分生区细胞有丝分裂活动减弱。

关键词: 大麦, 盐胁迫, 根冠, 分生区

Abstract: Changes occurring in cells in root tips of barley(Hordeum hulgare L.)inresponse to moderate salinity treatment were studied.The results were as follows.Saltcaused a decrease of starch grains in the root cap of barley.Starch grains appeared in cellsin the ground meristem region of barley root because of salt treatment.Salt treatment alsocaused a decrease of the mitosis frequency in the meristem region of barley root.

Key words: Barley (Hordeum uudgaure L.), Salt stress, Root cap, Meristem region
