摘要
尖萼耧斗莱(Aquilegia oxysepala Trautv.et Mey.)属毛莨科(Ranunculaceae)耧斗菜属(Aquilegia)植物。其幼苗初生维管系统的解剖学研究表明,它与毛莨科的其它属同样,存在一个以子叶节区为中心的两个过渡区。幼苗的初生维管系统可分为上胚轴苗区、子叶节区和下胚轴根区等三个区。解剖研究进一步验证了谷安根等(1990)提出的关于子叶节区理论是客观存在的,同时也为揭示毛莨科植物的起源和演化积累一份新资料。
Aquilegia oxysepala belongs to Ranunculaceae. Studies on the primaryvascular system of the seedling showed that A. oxysepala was the same as. other genera of the Ranunculaceae in that there were two transition regi-ons with the cotyledon node zone (CNZ) being the centre. The primaryvascular system of the seedling could be divided into the three parts: epi-cotyl shoot zone, cotyledon node zone and hypocotyl root zone. The resultsfurther verified that the cotyledon node zone proposed by Gu An-gen (1990)did exist, and also provided a new materal for the studies on the originand evolution of Ranunculaoeae.
