丹参营养器官发育解剖学研究

Development Anatomy of Salvia Miltiorrhiza Vegetative Organs

采用石蜡切片法及组织化学法研究了丹参营养器官的结构及常用药用部位的结构发育。结果表明:丹参根的结构、发育过程与一般双子叶植物相同。成熟根中,导管在次生木质部中呈放射状排列。茎为四棱形,4个棱角处有丰富的厚角组织,起支持作用。叶为异面叶,上下表皮均具大量的表皮毛。丹参根、茎、叶的解剖结构存在明显的旱生特征。

In order to study the structure of Salvia mihiorrhiza vegetative organs and the growth development of medicinal parts. Method Paraffin sectioning and histochemistry was used. The results show that the structure and growth development of the root of Salvia miltiorrhiza are the same with other dicotyledons. Vessels in secondary xylem are arranged radially. The stem is four arris. The leaf is dorsi-ventral, and there are abundant trichomes in the surface. The structure of vegetative organs of Salvia mihiorrhiza has a clear feature of drought.
