采用显微图像分析方法,对龙竹主要解剖特征进行了研究,为提高建筑用丛生竹资源高附加值加工利用水平提供理论。结果发现,龙竹薄壁细胞、纤维、导管和筛管比量分别为60.9%、34.6%、4.0%和2.1%。纤维直径、双壁厚、腔径和长度分别为19.043、9.518、9.525和2 546.235μm,纤维长宽比、壁腔比和腔径比分别为134.053、1.214和0.487。维管束径向直径和弦向直径分别为862.803和702.743μm,维管束密度为1.133个.mm-2。
Using microscopic image analysis method, the main anatomical characteristics of Longzhu bamboo were studied in order to provide theoretical basis for improving the high value-added processing and utilization level of bamboo resources in construction. The results showed that the ratio of pistillate cells, fibers, catheters and sieves was 60.9%, 34.6%, 4.0% and 2.1%, respectively. Fiber diameter, double wall thickness, cavity diameter and length were 19.043, 9.518, 9.525 and 2 546.235μm, respectively. The fiber aspect ratio, wall cavity ratio and cavity diameter ratio were 134.053, 1.214 and 0.487, respectively. The radial diameter and chordal diameter of the vascular bundles were 862.803 and 702.743μm, respectively, and the vascular bundle density was 1.133mm-2.
