摘　　要：研究了蒲菜营养器官的形态结构．蒲菜不定根根冠、皮层、维管柱起源于顶端分生组织中各自独立的３层原始细胞，表皮与皮层起源于共同的原始细胞．不定根具根毛，维管束为多原型．生长锥原套为２层．茎的维管束均分散在基本组织中，分为中央维管束和周围维管束．蒲叶两面均具栅栏组织．为等面叶，两表皮气孔器密度相似．叶脉的木质部均朝向叶近轴面．根、茎、叶薄壁组织中均含有不同发达程度的含晶细胞和乳汁细胞，并且均具发达的通气组织．The morphological structure of the vegetative organ of Typha latifolia L. have been studied. The root cap, the cortex and the vascular cylinder of the adventitious root are derived from three independent initials. Both the epidermis and the cortex originate from the same initial. The adventitious root possesses root hair. The vascular cylinder is polyarch.The tunica of the shoot apex of T. Latiflia have two layer of cells. The palisade parenchyma is present on both side of the leaf. The leaf is said to be isolateral. The adaxial epiderm and the abaxial epiderm have the similar density of stomata apparatus. The xylems of the veins all face towards to the abaxial epidermis. The crystal-containing cells and the laliciferous cells which have developed in varying degrees exixt in the parenchyma of the root, the stem and the leaf.The developed arenchyma also exist in the parenchyma of the vegetative organ.
