| 摘 要： | 竹子的秆形结构研究对竹林资源产量测算和秆材的利用等具有重要的意义．本文对实心狭叶方竹的秆形特性及变异规律进行了研究．实心狭叶方竹平均秆高为116．9cm，最高可达257．0cm；地径一般在1cm以下，平均为0．495cm，最大可达1．58cm；节间长一般为5—18cm，平均为11．1cm，最长达20．2cm；枝下高一般小于70cm，平均为44．1cm．竹秆的地径与秆高、枝下高、竹秆重量、节间数等特征的相关性极为显著，其相关系数分别为：0．949，0．971，0．921，0．886，三次方程最能反映地径与秆高、枝下高、秆重、节间数等特征的相关性，不同于其他竹种的研究结果．节间长度在竹秆中随着秆轴的升高表现出逐渐升高→基本稳定→逐渐下降的规律．结果表明，不同竹子其秆形各因子之间的变化规律性不强，其研究还需进一步深入．

| Abstract: | The investigation on the culm characteristic of bamboo is important for the estimation of biomass and the using of bamboo culm.This paper discussed the culm characteristic and its variation of Chimonobambusa angustifolia f.repleta population.The average height of C.repleta was 116.9 cm,the maximum was more than 257.0 cm;the diameter at the base of culm(DB) was less than 1cm,the average was 0.495 cm,the maximum was 1.58 cm;the length of the internode was 5 to18 cm,the average was 11.1 cm,the maximum was 20.2... |
