为合理开发利用棕榈藤资源,以高地钩叶藤和钩叶藤为研究对象,采用生物解剖学方法,系统分析各组织比量在径向和轴向的变化规律。结果表明,高地钩叶藤和钩叶藤薄壁组织、后生木质部大导管、纤维及筛管比量分别为59.6%和50.2%、15.9%和16.4%、19.6%和28.9%、4.9%和4.5%,其中薄壁组织比量高地钩叶藤比钩叶藤高18.7%,纤维比量低32.2%,经F检验差异在0.05、0.01水平上分别达到显著和极显著。径向由外向内,薄壁组织比量呈增大趋势,后生木质部大导管比量、纤维比量和筛管比量呈减小趋势。随着轴向高度的增加,高地钩叶藤薄壁组织比量、钩叶藤筛管比量先增大后减小,钩叶藤薄壁组织比量、高地钩叶藤后生木质部大导管比量不断增加,高地钩叶藤和钩叶藤纤维比量呈下降趋势。
In order to rationally develop and utilize the resources of the palm rattan, the highland hooked rattan and the hooked rattan were used as the research objects. The biological anatomical method was used to systematically analyze the changes of the proportion of each tissue in the radial and axial directions. The results showed that the ratio of major catheters, fibers and scaffolds in parenchyma and xylem of Hookweed and Hookweed were 59.6% and 50.2%, 15.9% and 16.4%, 19.6% and 28.9%, 4.9% and 4.5% respectively, , In which the ratio of parenchyma Hookwort was 18.7% and the fiber content was 32.2% higher than that of Hookwort, and the difference was significant at 0.05,0.01 level by F test. In the radial direction, the ratio of parenchyma and parenchyma increased with the increasing of the ratio of the outer diameter to the inner diameter. With the increase of axial height, the ratio of parenchyma tissue to the ratio of parenchyma to the ratio of pilasters increased firstly and then decreased, The amount of Hook’s hooked vine and hooked-leaf vine showed a decreasing trend.
