| 摘 要： | 对藏药狭叶红景天根、茎、叶等营养器官内部结构进行解剖学观察的结果表明：其内部结构除了具备一般双子叶植物的特征外，还具有根的薄壁组织及叶肉组织中具十分发达的胞间隙、根茎叶中均存在有单宁异细胞等特点、这些特点在植物适应高山缺氧环境、抵御不良气候条件方面有着积极的意义。此外，文中报道的结构特征在这种藏药的生药显微鉴定方面以及分类学上亦有一定的参考价值。

| Abstract: | The structure of the vegetative organs of Rhobiola Kirilowii(Regel)Maxim,which is one of the Tibetan pharmacutical plants,was anatomically studied.The structural characteristics of the plant are that there are aerenchyma being more developed through the plant development and abnomal cells changing in their numbers and contents during the development. We think that the features are significant for the plant to adapt to its habitat that is cold and lacking in oxygen. |
