摘要
采用抽样法,在福建周宁肿节少穗竹产区选取不同径级的标准竹201株作为研究对象,对胸径、全长、秆高、竹壁厚、节间长等指标进行统计和相关性分析。结果表明:胸径与秆高、秆重、总节数等秆形指标间的相关性较为显著,其中大部分以幂函数关系式得到较高的估测精度;肿节少穗竹的最长竹节在第5节左右,节长变化呈"短—长—短"的趋势。
201 standard Oligostachyum oedogonatum bamboos with various sizes in Zhouning, Fujian Province were sampled to study their relationships between the DBH, total length, culm height, wall thickness, and internode length. The results showed that the DBH is significantly correlated with culm height, weight and total number of nodes, and most of them could be well estimated by power functions. The longest internode length of Oligostachyum oedogonatum is located at about the 5th internode. The bamboo internode length varis with a trend of short- long-short＇
