| 摘要: |
| 通过对可采割枫香树(Liguidambar formosana H.Resin)的嫩枝和主茎解剖学观察,弄清了枫香树主茎树胶管的发生发育及分布规律:二年生嫩枝横切面上未发现有树胶管形成。在主茎次生木质部中的垂直与横向树胶管分别由形成层的纺缍状原始细胞和射线原始细胞衍生而来,以裂生方式发生和发育,分布于当年年轮线靠晚材部分,当年形成的树胶管具泌脂能力。次生木质部垂直和横向树胶管联结成二维系统。根据树胶管的发生发育及分布规律,提出相当的采脂方法。 |

| Abstract: |
| By anatomy observation of the main stems and twins of Beatitiful Sweetgum (Liquidambar formosana H. Resin) tapped, origination, development and distribution of the gum ducts in the aren'tfound to form on the cross section of biennial twins. The vertical and cross gum ducts in the secondary xylems of main stem are from the spindle and radial primary cells in the cambium respectively. They originate and develop through the schizogenesis, and distribute in the late-wood area around the same year annual ring. The gum ducts forming in the same year can secrete resin. The vertical and cross gum ducts in the secondary xylem bind a two-dimensional system. The resin-tapped methods have been raised according to the laws of origination, development and distribution of gum ducts. |
