蓝猪耳的显微鉴定

目的对蓝猪耳的显微特征进行研究。方法采用石蜡切片、粉末制片对蓝猪耳的茎、叶横切面组织显微结构及粉末特征进行研究。结果茎横切面四方形,四棱处向外凸起呈三角形,皮层内侧为一层扁平排列紧密的细胞,韧皮部较窄,外侧有纤维散在,断续排列成行,木质部于四角处较发达,导管多径向排列,髓部宽广;叶上下表皮细胞垂周壁弯曲,气孔不等式,栅栏组织1列,主脉维管束外韧形,半月形。结论上述特征可作为蓝猪耳显微鉴定的依据。

Microscopic identification of Torenia fournieri

Objective: To research the Torenia fournieri in microscopic characteristics. Methods: The microstructure and powder characteristics of T. fournieri stem, leaf cross sections were studied by using paraffin sections and powder production. Results: The transverse section of the stem is square, four outward convex is triangle, the inner cortex is a layer of flat closely arranged cells, the phloem is narrow, the outer fiber is scattered, arranged in rows discontinuous, the four corners of the xylem are advanced, the catheter is radial alignment, the pith is wide; The leaves of the upper and lower epidermal cell anticlinal wall is curved, stoma could be found in it, a row of palisade tissue, the main vein vascular is half-moon sharp. Conclutiion: These characteristics can be used as the basis of microscopic identification of T. fournieri.
