WoodAnatomy of Taxuschinensis var.maireifrom Wuyi County of Zhejiang Province

In 2015, wood of Taxuschinensis var. mairei(200-year) from Wuyicounty of Zhejiang province was intercepted and donated for researches. The apparent characteristics, microstructure, fiber morphology and distribution frequency of tracheid length were observed. The results showed that the early wood took the most part in tracheids with thin wall and large cavity, square or polygon fracture surface. While the late wood had little tracheids with thickwall and small cavity, rectangular fracture surface. The distribution of length of the early and late woodtracheids of heart or sapwoodwas normal. The average length of tracheids of heart wood was 3565.5 μm, and that ofof sapwood was 3249.4 μm. The average length of early wood fiber was 3308 μm, and that of late wood fiber was 3506 μm.
