| Abstract: |
| To provide basic data for the reasonable selection of high quality bamboo species as raw material for pulping and papermaking, the method of biological anatomy was used to investigate the anatomical characteristics of four sympodial bamboos (Bambusa chungii, Dendrocala-mus minor, Bambusa textilis, Bambusa pervariabilis).The results indicated that the morphology of vascular bundles in four sympodial bamboos was the type of broken-waist.The average fiber percentage, length, length-width ratio and wall-lumen ratio of these four bamboos ranged from 40.2% to 46.8%, 1.75 mm to 3.54 mm, 117 to 229 and 2.50 to 5.90, respectively.In the radial direction of the bamboo culm wall, the density of vascular bundles declined, but the double cell wall thickness increased from the outer zone to the inner.The maximums of length, width and lumen diameter of fiber were appeared in the middle of bamboo culm walls.The four sympodial bamboos were suitable as raw materials for pulping and papermaking, in which the fiber quality of Bambusa pervariabilis was similar to moso bamboo, but not as good as the other three species |
