白芷根、茎分泌组织的解剖学研究

The Anatomical Study on Secretory Tissue in Root and Stem of Angelica Dahurica

目的:研究白芷根和茎中分泌组织的结构特点和分布状况,旨在为探讨白芷体内次生代谢产物的发生及积累提供一定的解剖学资料。方法:采用石蜡切片辅以徒手切片的方法做根和茎的横切片、纵切片,并进行显微观察及显微测量。结果:白芷根、茎分泌组织在横切面均呈类圆形或椭圆形的腔,周围只有一层上皮细胞,无鞘细胞保卫;白芷根中分泌组织主要集中在韧皮部;茎的分泌组织主要集中在维管束附近。结论:该实验结果为白芷分泌结构与其次生代谢产物的相关性研究奠定了基础。

Objective：To study the structure and distribution characters of secretory tissue in the root and stem of Aneglica dahurica.Methods：Made paraffin section and freehand section,observe and photograph the microscopic charactersunder microscape.Results：Main characeristics of secretory tissue in the root and stem was obtained,such as the structure,type and distribution law.Conclusion：The study supports research on relevance of secretory tissue and secondary metabolite in Aneglica dahurica.
