Abstract: The basic density,component contents,and fiber morphology of bamboo culm (Dendrocalamus sinicus L.C.Chia et J.L.Sun) were analysed in this paper.The results indicated that these properties shown a certain amount of difference in different parts of bamboo culm.The basic density of the bamboo culm was 0.68 g/cm3,which was in the middle level among lignocellulosic biomass.In addition,the contents of holocellulose,lignin and pentosane were 71.01%,26.12% and 15.96%,respectively.The fiber length,fiber width,length/width ratio,and wall thickness/fiber lumen diameter ratio of the bamboo culm were 2.19 mm,19.61 μm,111 and 1.78,respectively.Overall,D.sinicus is one of qualified materials for pulping and papermaking due to its modest basic density,higher holocellulose content and better fiber morphology compared with other common fibrous raw materials.

Key words: Dendrocalamus sinicus, basic density, chemical composition, fiber morphology
