| 中文摘要: |
| 对2～5年生慈竹材的纤维形态和组织比量进行测定与分析。结果表明,慈竹纤维长度2.4～2.8 mm,纤维宽度14.5～16.0 μm,长宽比大于150,细胞壁厚10.4～11.5 μm,壁腔比2.3～2.6。慈竹材基本组织比量44%～50%，纤维组织比量39%～43%，输导组织比量8%～13%。在竹秆径向,纤维长度、宽度、长宽比及腔径均表现为中部较大,而细胞壁厚表现为外侧较大；在竹秆纵向,纤维长度、长宽比、细胞壁厚、壁腔比随竹秆高度增加呈先增大后降低趋势,纤维腔径、基本组织比量随竹秆高度增加逐渐减小。 |
| Abstract: |
| In this investigation, the fiber morphologies and tissue proportions of Neosinocalamus affinis culms at the ages of 2～5 years were measured and analyzed. The results showed that the values of bamboo fiber length, width, length/width ratio, cell wall thickness, and cell wall thickness/lumen diameter ratio were 2.4～2.8 mm, 14.5～16.0 μm, 150, 10.4～11.5 μm and 2.3～2.6 respectively. The fiber cell wall thickness and ground tissue proportion showed an increasing trend with the increase of bamboo culms ages. In the radial direction of bamboo culm, the values of fiber length, width, length/width ratio, and lumen diameter in middle layer are longer than that in the epidermis and wax layers, while cell wall is thicker in the epidermis layer samples. The fiber length, width, length/width ratio, lumen diameter and conducting tissue proportion increased, but the fiber lumen diameter, ground tissue proportion decreased from base to top. |
