摘要： 以耐盐品种枝棉3号和盐敏感品种鲁棉6号为材料，利用石蜡包埋切片法，分析盐胁迫下叶片细胞结构的变化。结果表明，0.1％NaCl浓度下，枝棉3号叶片细胞结构表现正常，鲁棉6号韧皮部组织受损较重；0.2％NaCl浓度下，两品种叶片细胞韧皮部的筛管均受损严重，且鲁棉3号比枝棉6号受损严重；0.5％NaCl浓度下，鲁棉6号木质部的导管也受损，枝棉3号木质部组织受损较轻。

Abstract: Salt-tolerant and salt-sensitive varieties were used to observe leaf cell structure under salt-stress condition. Cell structure of Zhimian 3 was normal and phloem of Lumian 6 was injured seriously under 0.1％ NaCl. Phloem of two varieties was injured seriously under 0.2％ NaCl. Xylem of Lumian 6 was also injured seriously and that of Zhimian 3 was injured slightly under 0.5％ NaCl.
