| 中文摘要: |
| 对6种分属于散生、丛生和混生竹材的解剖结构进行了对比研究，结果表明，6个竹种的维管束密度介于1.9~3.3个/μm2，维管束径弦向长度分别为375~617 μm、412~545 μm，径弦向长度比0.9~1.2。6个竹种的纤维组织比量、薄壁组织比量和输导组织比量分别介于10%~40%、51%~83%和6%~14%。6个竹种的纤维、薄壁组织细胞和导管的双壁厚、腔径和壁腔比在竹青、竹中和竹黄中的变化趋势未表现出明显的规律。除薄壁组织细胞的腔径在竹种之间不存在显著差异之外，纤维和导管的双壁厚、腔径和壁腔比以及薄壁组织细胞的双壁厚和壁腔比均存在显著差异。 |
| Abstract: |
| The anatomical characteristics of 6 bamboo species including scattering, mixed and caespitose growing bamboos were compared. The frequency of vascular bundle of six bamboo species ranges from 1.9~3.3 numbers/μm2. The radial and chord width of the vascular bundle and their ratio range from 375~617 μm, 412~545 μm and 0.9~1.2 respectively. Fibre, parenchyma and conductive tissue proportion of 6 bamboo species range from 10%~14%, 51%~83% and 6%~14% respectively. The double cell-wall thickness, lumen diameter and their ratio of fibre, parenchyma and vessel present irregular change pattern in tangential direction. The double cell-wall thickness, lumen diameter and cell wall thickness/diameter ratio of fibre and vessel as well as double cell-wall thickness and cell wall thickness/diameter ratio of parenchyma have significant differances among species, but not in lumen diameter of parenchyma. |
