Culm Form Characteristic and Fiber Morphology of Phyllostachys reticulata ‘Shouzhu’

In order to understand material and papermaking properties of Phyllostachys reticulata 'Shouzhu',P.edulis and Bambusa emeiensis L.C.Chia H.L.Fung were collected as controls,culm form,volume biomass and fiber morphology of P.reticulata 'Shouzhu' were studied.The results showed that the internode length of 'Shouzhu' was long at first,and then short along culm height,and the diameter and culm wall thickness decreased with increment of culm height.The model for 'Shouzhu' volume was V = 0.000939H + 0.001861D–0.01374,and W = 1.297D + 2.053H–16.666 for biomass.The average length of 'Shouzhu' fibers was 2.47 mm,most ranges from 2 to 3 mm,and the ratio of fiber length to width was more than 100,and the ratio of cell wall to cavity was 3.85.Compared with P.edulis,the internode length of P.reticulata 'Shouzhu' culm was long,volume distribution in vertical direction was even,and fiber was long with big ratio of length to width.Compared to B.emeiensis,the fiber length of 'Shouzhu' had little difference,the ratio of length to width was small with big ratio of cell wall to cavity.These indicated that P.reticulata 'Shouzhu' could be used for sheet and papremaking materials,which papermaking properties of P.reticulata 'Shouzhu' was better than P.edulis but under B.emeiensis.
