摘要:
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2 546.235 μm,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702.743 μm,维管束密度为1.133个·mm-2

Abstract:
In order to improve the levels of high value-added processing and utilizing for sympodial bamboo, the main anatomical characteristics of D. giganteus have been studied with the microscopic image analysis method. The results are as follows: the proportion of parenchyma, fiber, vessel and sieve tube are 60.9%, 34.6%, 4.0% and 2.1%, respectively. The average values of fiber width, double-wall thickness, lumen diameter, length, length-width ratio, double-wall thickness-lumen diameter ratio and lumen diameter-width ratio are 19.043 μm, 9.518 μm, 9.525 μm, 2 546.235 μm, 134.053, 1.214 and 0.487, respectively. The radial width, tangential width and frequency of vascular bundle are 862.803 μm, 702.743 μm, and 1.133 individual·mm-2, respectively.
Key words:  Dendrocalamus giganteus  anatomical characteristics  radial variation  variance analysis
