利用解剖学和组织化学的方法,研究了野生和栽培白头翁(Pulsatilla chinensis)主根的解剖结构和皂苷组织化学定位。结果表明:野生白头翁根部韧皮纤维散在,而栽培白头翁的则多个聚集成环状或其它形状;栽培白头翁根的次生木质部导管管腔内富含侵填体;野生白头翁根中分泌腔和分泌道丰富;分泌腔与分泌道的数量及大小是决定白头翁皂苷物质含量高低的主要因子。因此,分泌腔与分泌道大小和数量的多寡可以作为判断所选育的白头翁品种是否优良的结构性指标。 Anatomical and histochemical methods were used to study the anatomical structure and saponin histochemistry of the main roots of wild and cultivated Pulsatilla chinensis. The results showed that the roots of wild Pulsatilla were dispersed in the bast fibers while the cultivated Pulsatilla aggregated into rings or other shapes. The secondary xylem duct of the cultivated Pulsatilla was rich in tundra, Secretion rich; secretory cavity and the secretion of the number and size of Pulsatilla saponin substance content is the main factor. Therefore, the size and quantity of secretory cavity and secretion can be used as a structural index to judge whether the breed Pulsatilla is excellent.
