| 摘 要： | 本文探讨了云杉属（ＰｉｃｅａＤｉｅｔｒ．）树种木材中的独特的云杉型加厚（即射线管胞内壁具有近似平直端部的矩形加厚）、射线管胞及轴向管胞内壁的螺纹加厚和射线管胞内壁上的细锯齿状加厚。本文还讨论了云杉属及其近缘各属木材由于螺纹加厚对次生木质部进化的影响。

| Abstract: | Studies were conducted on particular piceaoid projections (i.e.the rectangular projections with approximately flat and straight ends), the toothlike projections and the spiral thicking on the inner walls of ray tracheids and the spiral thicking on the inner walls of the the axial tracheids. The discussion deals with the evolution (phylogenesis) of secondary xylem exhibited by the comparison between spiral thickings inPicea and its close relative genera. |
