摘要
对侧金盏花营养器官进行解剖观察，结果表明，（1）根部表皮细胞的外切向壁及径向壁呈马蹄形栓质化加厚，维管柱内木质部脊数为2～3原型；（2）根状茎具有维管形成层，能进行微弱的次生生长，皮层细胞含有丰富的淀粉颗粒；（3）茎的髓部为疏松的薄壁组织，维管柬环形排列，木质部呈“v”字形；（4）叶柄呈凹圆形，外皮层细胞富含碱性颗粒．
Anatomic structure of vegetative organs of Adonis amurensis were studied, and the results showed that, （ 1 ） the root epidermis cells have corktified suberisation outer tangential wall and radial wails, and vascular cylinder has diarch or triarch xylem, （ 2 ） rhizome has vascular cambium and slight secondary growth, parenchyma cells have rich starch grains, （ 3 ） stem pith is composed of spongy parenchyma, and a ring of vascular bundles have V-shaped xylem, （ 4 ） saucer shaped petiole has basophilic granule in exdodermis ceils.
