侧金盏花营养器官的解剖研究

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，维管束环形排列，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 walls,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 cells.
