초록
목재의 강도에 영향을 미치는 인자는 다양하기 때문에 본 연구에서는 국산 참나무 아속 주요수종인 굴참나무, 갈참나무, 졸참나무, 신갈나무, 상수리나무를 대상으로 해부학적 특성과 휨강도와의 관계를 규명하여 참나무 아속의 합리적인 이용방안을 위한 기초자료를 얻었다. 해부학적 특성가운데 휨강도에 가장크게 영향을 미치는 인자는 굴참나무는
This study was carried out to get some basic information on mechanical properties of Korean Lepidobalanus for the rational utilization of their woods, Five species of Quercus variabilis, Q. aliena, Q. serrata, Q. mongolica, Q. acutissima belonging to Lepidobalanus were investigated in this research. Relationship of anatomical characteristics with bending strength was analyzed using stepwise regression technique. All possible combination of 21 independent variables were regressed on bending strength. The summarized results in this study were as follows: 1) In the proportion of wood structural elements, the most important factors on bending strength appeared to be proportion of wood fiber in earlywood in Q. variabilis and Q. serrate, proportion of ray in earlywood in Q. aliena, proportion of vessel in earlywood in Q. mongolica and proportion of wood fiber in latewood in Q. acutissima, respectively. 2) In the other quantitative anatomical characteristics, the most important factors on bending strength appeared to be number of pore per
