Study on Fiber Forms and Tissue Measurements of Bambusa wenchouensis Wood

The fiber forms and tissue measurements of Bambusa wenchouensis wood in the southern area in Zhejiang province were tested and compared with those of B. textilis and Dendrocal_amopsis oldhami. The analytic results showed that the fiber length (L) of B. wenchouensis was 2.24 mm, a little shorter than that of B. textilis (2.29 mm)but longer than D. oldhami(1.87 mm); the ratio of fiber length to width (L/W) was 166, the largest one among the three woods, and those of the other bamboospe cies were 147 and 131 respectively; the ratio of wall thickness of fiber cell to the cavity diameter (T/D) was 3.5; measurements of fiber tissue was 48.68%, a bit smaller than that of B. textilis (50.19%)but larger than D. oldhami(45.78%). The fiber forms and tissue measurements were variable in both axial and radial parts of this bamboo: T/D and fiber tissue measurements increased gradually from the culm foot to tip; the fiber length and L/W both were the largest in the central bamboo wall, while T/D was the highest in the outer wall. The age had a significant influence on T/D, which was much larger of 1 or 3-year-old wood than that of month-old wood.
