    毛竹来鞭的纤维形态特征及差异性

    Comparative study on morphological characters and differences of fiber in Phyllostachys pubescens coming parts of rhizomes among different growth ages.

    • 摘要: 运用显微自动成像技术和双侧Z 值检验显著性,对1 年生、3 年生、5 年生毛竹来鞭的纤维形态特征及差异性 进行了研究。结果表明:1)地下茎来鞭平均纤维长度698.555 m、纤维直径21.710 m、纤维腔径11.375 m、双壁 厚5.167 m、壁腔比0.483、腔径比0.522、长宽比34.723。2)纤维长度与长宽比均有1 年生与3 年生差异极显著、 1 年生与5 年生差异不显著、3 年生与5 年生差异极显著的特点,纤维直径与纤维腔径均差异不显著,双壁厚、壁腔 比与腔径比均有1 年生与3 年生差异显著、1 年生与5 年生差异极显著、3 年生与5 年生差异不显著的特点。毛竹 地下茎来鞭的纤维形态特征符合纸浆材要求,但与双子叶植物相比不是十分优质的原料。

       

      Abstract: Fiber morphological features of Phyllostachys pubescens coming parts of rhizome at 1-, 3-and 5-year- old were examined by digital light microscopy, and the differences among them were analyzed by Z value two-sided test. The results indicated that the average values of fiber length, fiber diameter, fiber lumen diameter, double-wall thickness, ratio of wall thickness to lumen diameter, ratio of lumen diameter to fiber diameter, and ratio of fiber length to width collected from all P. pubescens rhizome samples were 698.555 m, 21.710 m, 11.375 m, 5.167 m, 0.483, 0.522 and 34.723 respectively. Both fiber length and ratio of fiber length to width were significantly different between 1-and 3-year-old P. pubescens rhizomes, while the difference was insignificant between 1-and 5-year-old P. pubescens rhizomes. However, comparisons between 3-and 5-year-old rhizomes had showed that the differences were significant at 0.01 level. No significant differences were found in fiber diameter and lumen diameter among three ages. When it came to double-cell-wall thickness, ratio of wall thickness to lumen diameter, ratio of lumen diameter to fiber diameter, the difference was significant at 0.05 level for 1-and 3-year- old, significant at 0.01 level for 1- and 5-year-old , and was insignificant for 3- and 5-year-old P. pubescens rhizome. Therefore, fiber morphological features of P. pubescens rhizome meet the qualification as resource of paper pulp, but it still inferior to dicotyledon plants in point view of paper pulp.
