摘　　要：[目的]研究北药白鲜的生物学特征并观察其茎叶的解剖结构。[方法]采用石蜡制片的方法研究北药白鲜的茎叶解剖结构特征。[结果]白鲜的茎由表皮、皮层和维管柱3部分组成,皮层由厚角组织和薄壁组织构成,维管束环状排列,由外到内依次是韧皮部和木质部。叶片为典型的异叶面,由表皮、叶肉及维管束构成,表皮细胞排列规则,叶肉分为栅栏组织和海绵组织,分化明显。[结论]该方法研究了北药白鲜的生物学特征,并观察其茎叶的解剖结构,效果良好。[Objective] To study the biological characteristics and anatomical structure of leaf and stem of Dictamnus dasycarpus Turcz.[Method] The anatomical structure of leaf and steam of D.dasycarpus was studied by the method of paraffin sectioning.[Result] The stem of Dictamnus dasycarpus Turcz consisted of epidermis,cortex and vascular cylinder.The cortex was composed by collenchyma and parenchyma tissue.The vascular cylinder was arranged as a ring,which from outside to inside were phloem and xylem.The leaf was typical bifacial leaf which consisted of epidermis,mesophyll and vascular cylinder.The epidermal cells were arranged regularly.The mesophyll consisted of palisade tissue and spongy tissue differentiation.[Conclusion] The method well studied the biological characteristics of Dictamnus dasycarpus Turcz and observed their anatomical structure.
