蜈蚣草导管分子的观察

Study of Vessel Elements in Pteris vittata

  • 摘要: 对蜈蚣草(Pteris vittata)叶轴中导管分子进行了观察。结果表明,其导管分子十分细长,均具长、且十分倾斜的梯状穿孔板,穿孔没有纹孔膜的残余,与侧壁上的梯纹纹孔有着明显的差异。

     

    Abstract: The vessel elements in rachis of Pteris vittata are observed and studied in this paper.The result shows that all of the vessel elements are very long.The scalariform perforation plates which are very long and gradient are in the either of end wall of vessel elements,there are a lot of perforations without pit membrane in these plates.The scalariform perforation plate in the P.vittata differs greatly from the scalariform pitting in side wall in conformation and structure.It is discussed that the vessel elements and the scalariform perforation plate in P.vittata.
