蓝堇草幼苗初生维管系统的解剖学研究

Anatomical Studies on the Primary Vascular System of the Seedling of Leptopyrum Fumarioides Reich

蓝堇草（ＬｅｐｔｏｐｙｒｕｍｆｕｍａｒｉｏｉｄｅｓＲｅｉｃｈ）属毛茛科（Ｒａｎｕｎｃｕｌａｃｅａｅ）蓝堇草属（Ｌｅｐｔｏｐｙｒｕｍ）植物。其幼苗初生维管系统的解剖学研究表明，它与毛茛科其它属一样，存在一个以子叶节区为中心的两个过渡区。向上为子叶节──茎过渡区；向下其下胚轴为子叶节─—根过渡区。

Leptopyrum fumarioides Reich belong to Leptopyrum of Ranunculaceae. Its seedling apparently divided into three zones: epicotyl shoot zone, cotyledon node zone (CNZ) and bypocotyl root zone.The seedling is with the center of the CNZ, the middle and upper parts of the CNZ upward are cotyledon─node─stem transitional region and the hypocotyl of the seedling downward is cotyledonnode─root transitional region.
