树胶管 sum duct 为分泌道的一种,具有与树脂道类似的结构。主要见于被子植物的材质部分,分泌树胶质、树脂、精油、粘液等。在胞间隙以裂生的或溶生的方式形成,也有时以两种方式形成的。树胶质为碳水化物,主要来源于淀粉的分解物,有时因受伤或致病等而列解的细胞变为树胶质(流胶gumosis)。
根据树胶管的发生发育及分布规律,提出相当的采脂方法。
The resin - tapped methods have been raised according to the laws of origination, development and distribution of gum ducts.
物理性能:单散孔,含树胶沉积物,侵填体丰富,导管与射线间纹孔小,轴向薄壁组织为傍管型,主为聚翼状,带状也常见。
Physical properties: a single scattering holes, including gum sediments, tylosis rich, catheter and ray pits between small, axial parenchyma as paratracheal type, main poly of, ribbon is also common.
