The results showed that NaCl stress decreased the seedlings fresh mass and dry mass significantly. Under NaCl stress, the relative contents of Na(superscript +) and Cl(superscript -) in cells increased significantly, but the increment somewhat differed with different tissues. In root and stem, epidermal cells had the greatest increment, followed by cortex cells, and stelar cells; while in leaf, epidermal cells had the greatest increment, followed by cortex cells, spongy tissue cells, and palisade tissue cells.
结果表明:NaCl能显著降低长春花幼苗的鲜质量和干质量;对根、茎和叶片横切面X射线微区分析表明,NaCl胁迫导致长春花体内各组织细胞中Na和Cl相对含量显著增加,但在各器官、组织中分布稍有不同:与对照相比,根和茎中都是表皮细胞中增加幅度最大,中柱细胞次之,皮层细胞最低;在叶片中亦是表皮细胞增加幅度最大,依次是皮层细胞、海绵组织细胞及栅栏组织细胞。
