| 目的 研究椰子叶柄不同部位的纤维形态、 维管束形态及组织比量等解剖特性。方法 采用富兰克林离析法分离纤维， 用Motic Images Plus 2.0软件测量纤维长度、 宽度和腔径等形态参数。同时， 用Images Pro Plus软件观察切片后维管束的形态， 并测量其大小、 密度及组织比量等参数。结果 椰子叶柄的纤维长宽比为72， 壁腔比为0.95， 属于均匀分布的长纤维原料。椰子叶柄的维管束均匀分散于薄壁组织中， 并于纵向呈现一定规律， 其长轴、 短轴、 面积均由基部至梢部依次减小， 密度及长宽比均是梢部最大。椰子叶柄的纤维组织比量高， 且随基部至梢部含量增多。结论 这是一种优良的植物纤维原料， 可用于制备优质的包装用纸， 并可在复合材料中发挥增强作用。 |

| Objective To investigate the variation characteristics in different parts of coconut petiole through a test on the fiber morphology, vascular morphology and tissue proportion. Methods Fibers were separated using Franklin segregation. Then their length, width and the cavity size were measured by Motic Images Plus2.0. Moreover, the shape of vascular bundle was observed and its size, density and tissue parameters were measured with Images Pro Plus. Results The fiber of coconut petiole was a long and well-distributed raw material with a length-width ratio of 72, and a wall-lumen ratio of 0.95. The vascular bundles were evenly dispersed in the thin wall. The long axis, short axis, and the area were smaller from the base to the tip, while the density and length-width ratio were the maximum on the tip. The fiber proportion was high, and increased from the base to the tip. Conclusion Coconut petiole is a superior plant fiber raw material, which can be used for production of high-quality packaging paper and reinforced compact material. |
