青钱柳解剖性质研究

A Study of Anatomical Properties of Cyclocarya paliurus

以青钱柳(cyclocarya paliurus)树干1.3 m处圆盘为研究对象,通过木材解剖测定其生长轮纤维长度、宽度、长宽比、壁厚、腔径、壁腔比和导管长度、宽度、长宽比、壁厚、腔径、壁腔比,研究各个指标随生长轮龄增长的径向变异规律。结果表明:青钱柳纤维长度、纤维长宽比随生长轮龄的增长总体呈增长的径向变异规律;而纤维宽度、纤维壁厚、纤维腔径、纤维壁腔比随生长轮龄的增长没有明显的变异规律。青钱柳导管长度、导管宽度、导管壁厚、导管腔径随生长轮龄的增长总体呈增长的径向变异规律;导管长宽比、导管壁腔比随生长轮龄的增长没有明显的变异规律。

In ths paper, taking disks of Cyclocarya paliurus trunk at 1.3 m as the research object, through the wood anatomic method measurement was conducted on its growth round fiber length, width, aspect ratio, cavity diameter, wall thickness, wall cavity ratio and tube length, width, aspect ratio, cavity diameter, wall thickness and wall cavity ratio, and studies were made of the various indicators along with the growth ring radial variation patterns of age growth. The results showed that Cyclocarya paliurus fiber length and fiber length-width ratio along with the growth of the age of growth ring overall had a growing radial variation law ; And fiber width, fiber wall thickness, diameter, fiber wall cavity ratio along with the growth of the age of growth ring exhibited no obvious variation regularity. Cyclocarya paliurus catheter in the wall thickness, length, width of catheter, guide catheter lumen diameter along with the growth of the age of growth ring radial variation regularity of overall increased ; Catheter length-width ratio, guide wall cavity ratio along with the growth of the growth ring of age had no obvious variation rule.
