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。

Diffuse-porous Describing wood in which vessels of approximately equal diameter tend to be evenly distributed so there is no obvious growth ring.

散孔：用于木材识别的一种类型。这类木材导管均匀分布于年轮中，横切面上早材至晚材的管孔大小一致。

Sectioning across the adrenals reveals a golden yellow outer cortex and an inner red to grey medulla.

肾上腺的横切面显示出外部金黄*色皮质和内部灰红色的髓质。

Sectioning across the adrenals reveals a golden yellow outer cortex and an inner red to grey medulla.

正常肾上腺的横切面可见位于外侧的金黄色的皮质和位于内侧的淡红色的髓质。

Anatomical characters that are of significance are terminal sclereids, druses in epidermalcells, trichomes, brachysclereids in parenchymatous tissues of midribs and petioles, and theshape of midribs and petioles in transverse sections.

有意义的解剖学特征是：末端石细胞，表皮细胞的晶簇，毛状体，在中脉和叶柄的薄壁组织内的短石细胞以及中脉和叶柄横切面的形状。

The color surface, texture, the size of pith and the arrange of vascular bundle was observed with freshed, dried drugs and the transverse section, the effective component of echinacoside and acteoside was analyzed with hplc and the amylose was anlyzed with ultraviolet spectrophotometry.

药材性状和结构直接观察肉苁蓉新鲜及晒干或阴干的表面颜色和质地，以及横切面颜色、质地、中心髓部大小及维管束排列等；高效液相色谱法测定药材有效成分松果菊苷及毛蕊花糖苷的含量；紫外分光光度法测定药材粗多糖含量。

The cells in cross-section of leaf and stem become swollen and intercellular space of the ground tissue increass when the expression of UDPGDH gene was inhibited in tobacco. When UDPGDH gene was over expresed, opposite physiological changes were observed. These results further suggested that UDPGDH gene may play an important role in the synthesis of pectin and hemicelluloses in ramie.

初步的组织学分析表明，反义和干扰表达的转基因植株中，茎段与叶横切面细胞结构较为松散，基本组织细胞间隙增大，而在UDPGDH基因过量表达的转基因植株中则观察到相反的现象，进一步证实UDPGDH基因在苎麻半纤维素和果胶合成中所具有的重要作用。
