目的:对红花地上部分的显微结构进行研究。方法:用常规显微技术观察组织结构和粉末特征。结果:叶上下表面均有不等式气孔。叶肉组织排列疏松,有红棕色的分泌细胞散在;主脉维管束外韧型,韧皮部、木质部周围均有纤维束伴随。茎维管束外韧型,有微木化的韧皮纤维束;木质部内侧也有微木化的纤维群;髓部较宽广。粉末中,分泌细胞长管道状,胞腔内充满黄色或红棕色分泌物,含菊糖,气孔不定式,纤维成束,多与导管相伴,导管多为螺纹导管。结论:以上特征可以作为红花地上部分的主要显微鉴定依据。
Objective: To study the microstructure of safflower aerial parts. Methods: Microstructural and powder features were observed using conventional microscopy. Results: The upper and lower leaves have inequalities of stomata. Leaf tissue arranged loosely, with reddish brown secreting cells scattered; main vein vascular bundle toughness, phloem, xylem around the fiber bundles are accompanied. Stem vascular outside the tough type, a micro-wood bast fiber bundle; inside the xylem also has a micro-wood fiber group; broad pith. Powder, secreting cells long tube-like, filled with yellow or red-brown cell secretions secretions, including inulin, stomatal infinitive, bundles of fibers, and more accompanied by the catheter, the catheter is mostly threaded catheter. Conclusion: The above characteristics can be used as the main microsatellite identification of safflower aerial parts.
