白桦根的木材解剖学研究

Studies on Wood Anatomy of Betula Platyphylla's Root

对白桦根次生木质部进行木材解剖学研究 ,发现其为散孔材 ,管孔多数为复管孔 ,少数为单管孔 ,为同形射线 ,导管分子穿孔板类型为梯状穿孔板 。

Researching the root's secondary xylem of Betula platyphylla revealed it's diffuse-porus wood. Most of the pore is solitary pore and the other is multiple pore. Ray is homogeneous. The type of vassle element is scalarform perforation plate. There are abundant libriform wood fibre in dispersal.
