| 摘 要： | 毛竹节间长度、周长、壁厚等是影响竹材加工利用的重要秆材性状。首次报道了不同海拔区域毛竹人工林这些节间主要性状在竹秆上的分布规律及其海拔效应。试验结果表明 ,毛竹节间长度、周长和壁厚与节间数之间分别存在着抛物线、直线和对数相关关系 ,前 5 0节节长和周长均值随海拔的升高而降低 ,而壁厚随海拔升高的变化不明显

| Abstract: | Internode length ,diameter and culm-wall thickness are very important characters influencing process and utilization of Mao bamboo (Phyllostachys pubescens) culm. For the first time, this paper reports on the distribution pattern of these main characters on the culm in plantations at different altitudes and on its altitude effect. The results indicated that there were parabolical, linear and logarithmic relationships between internode length, diameter, culm-wall thickness and node number respectively. Internode length and diameter of the first fifty nodes were found to decrease with altitude, while culm-wall thickness was not related to altitude. |
