| 摘 要： | 离析笃斯越桔根次生木质部，其细胞组成有纤维管胞；一端为网状穿孔板，另一端为孔纹增厚的导管分子；两端均为网状穿孔板的导管分子；一端为网状穿孔板，另一端为梯状穿孔板的导管分子；一端为梯状穿孔板，另一端为单穿孔板的导管分子；两端均为雌穿孔板的导管分子．在笃斯越桔根的个休发育过程中重演了导管分子穿孔板的系统演化过程．

| Abstract: | Dispersed material of the stem secondary xylem of Vaccinium uliginosum , showing the fiber tracheid on it; the vessel element of one end has reticular perforation plate and the other end has pitted thickening; the vessel of each end has reticular perforation plate; the vessel element of one end has reticular perforation plate and the other end has scalarform perforation; Vessel of Scalarform perforation plate in one end and simple perforation plate in the other end;Vessel of two top walls have simple perforation plate. The phylogeny process of the perforation plate is recapitulated in the ontogeny process of the Vaccinium uliginosum root. |
