以21種生長于台灣的竹種為實驗材料，依據竹稈徑分成三類型：A（稈徑＜25 mm），B（25 mm＜稈徑＜45 mm），及C（稈徑＞45 mm）加以評估，調查稈形特性包括節間長，稈徑，稈壁厚，稈壁率及其綜合性。實驗結果顯示竹種間有不同的稈形特性，而竹種之工藝性質評估可先由稈徑加以分類，藉此獲得稈形特性，應再考慮不同利用形態時之狀況。
Twenty-one bamboo species grown in Taiwan were selected for the investigating of the culm-form characteristics including internode length, culm diameter, culm wall thickness, culm wall fraction, and their over-all evaluation. The samples could be classified into three types on the basis of culm diameter namely: Type A (culm diameter ＜ 25 mm), Type B (25 mm ＜ culm diameter ＜ 45 mm), and Type C ( culm diameter ＞45 mm). The surveyed specimens show different value with species in all culm-form characteristics. This study showed that this method could be used to evaluate the relevant properties regarding to the potential application of bamboo. Culm-form characteristics should be considered individually for different types of utilization.
