Abstract
Anatomical and physical characteristics of damaged wood by forest fire and sound wood of Pinus densiflora were examined. Granular substances were found in resin canals, epithelial cells and ray parenchyma cells of damaged wood, but the other distinctive marks of wood structure in damaged wood were not observed. Damaged wood showed slightly higher relative crystallinity in outermost growth ring than sound wood. Green moisture content and water absorptions both in tangential and radial sections of damaged wood were lower than those of sound wood. There were no significant differences in shrinkage, swelling and basic density between damaged and sound woods.
본 연구에서는 산불 피해를 입은 소나무재의 유효 활용을 위한 기초자료를 얻고자 해부 및 물리학적 특성을 조사하였다. 산불 피해재의 수지구, 에피델리얼세포와 방사유세포내에는 건전재와 달리 과립모양의 물질이 많이 존재하였으며, 그 외의 목부 조직구조는 정상재와 거의 차이가 없었다. 건전재와 비교하여, 산불 피해재는 상대결정화도가 다소 높았으며, 생재함수율과 접선 및 방사단면 흡수량은 다소 낮게 나타났다. 수축율 및 팽윤율과 기본밀도는 정상재와 거의 유사한 값을 보여주었다.
