摘　　要：研究了大型丛生竹种车筒竹Bambusa sinospinosa,箣竹Bambusa blumeana和越南巨竹Dendrocalamus yunnanicus竹材的纤维形态和组织比量,并与造纸性能良好的青皮竹Bambusa textilis做比较。结果表明:车筒竹、箣竹和越南巨竹竹材纤维长度分别为2.37,2.27和2.49 mm,属于长纤维原料,且高于青皮竹;纤维长宽比分别达145,124和128,与青皮竹相当或略小,壁腔比均小于青皮竹的相应值;纤维组织比量分别为49.79%,45.95%和50.50%。从分析结果看,3竹种具有较好的纤维形态和较高的纤维组织比量,适宜做制浆原料。To evaluate the suitability for paper-making of Bambusa sinospinosa,Bambusa blumeana,and Dendrocalamus yunnanicus,the stem fiber foms and tissue measurements of three sympodial bamboos were studied and compared to those of Bambusa textilis,which possesses favorable paper making capabilities.Analytical results showed that fiber lengths（L） of the three sympodial bamboos（B.sinospinosa 2.37 mm,B.blumeana 2.27 mm,and D.yunnanicus 2.49 mm） were longer than that of B.textilis（2.19 mm）,and all three bamboos belonged to the long-fiber plant material category.The fiber length to width ratios（L/W） of the three bamboos（B.sinospinosa 145,B.blumeana 124,and D.yunnanicus 128） were equal to or a little lower than that of B.textilis;whereas the ratio of wall thickness for fiber cell to the cavity diameter（T/D） of the three bamboos were lower.Also,fiber tissue measurements were：B.sinospinosa 49.79%,B.blumeana 45.95%,and D.yunnanicus 50.50%.The three sympodial bamboos had good fiber form and tissue measurements for paper-making meaning all three were suitable as a raw material for paper.[Ch,2 fig.3 tab.16 ref.]
