摘要

本研究以節間長、稈徑、稈厚與稈壁率來評估台灣產之綠竹、烏腳綠竹、八芝蘭竹、竹變與印度實竹之性質以為工藝利用時之參考，結果顯示無單一竹種在各評估因子皆佳，本研究的竹種之各項桿形因子較先前研究的竹種稍差，印度實竹與烏腳綠竹在5種竹中之均勻性是較佳的，而且稈壁率又高，八芝蘭竹之釋壁率雖高但各稈形因子的評估居次，綠竹與竹變之綜合乎稈形因子的評定上稍差而且稈壁率亦低。在利用上應視用途依評估因子而選擇竹種，應即針對各竹種之優良稈形而加以應用。

The purpose of this study is to investigate the industrial utilization values of five bamboo species, Bambusa oldhamii(BO), B. edulis(BE), B. pachinensis(BP), B. beechyana var. pubescens(BB) and Dendrocalamus strictus(DS) , by means of some culm form factors, including internode length, culm diameter , culm wall thickness and culm wall fraction. The results revealed that no one species show the best value in all culm form factors. All five species were inferior to the bamboo species of former study. Culm form evaluation factors should be respectively considered depending on the type of utilization. The culm form of DS and BE showed more homogeneous than other three bamboo species and the two species had high culm wall fraction. BP also had high culm wall fraction' but intermediate culm form quality. To sum up all culm form evaluation, BO and BB were inferior to other three species as well as their lower culm wall fraction.
