초록

종자의 산지가 다른 루브라참나무(24년생)를 대상으로 물리 및 역학적 관계를 조사하여 생장속도와 목재의 재질과의 관계를 규명하였다. 생재함수율은 변재보다 심재가 높은 것으로 나타났고, 산지 간에 차이를 나타냈다. 비중의 경우 심재는 생장이 좋을수록 작아지는 경향을 보였고, 변재는 생장이 좋을수록 커지는 관계를 나타냈다. 전수축률은 산지간 차이를 나타냈으며, 생장이 좋을수록 수축률과 T/R율은 높아지는 것으로 나타났다. 압축영계수, 휨강도와 휨영계수 및 충격강도는 산지 간 차이를 보였으며, 생장이 좋을수록 낮아지는 경향을 보였다. 전단강도는 산지 간 차이를 보였으며, 생장이 좋을수록 커지는 경향을 보였다. 경도는 세 단면에서 산지 간 차이를 보였으며, 생장이 좋을수록 커지는 경향을 나타냈다. 5종의 산지가 다른 루브라참나무 중 Bancroft산 종자의 경우가 가장 좋은 수고생장을 보이고, 세 번째의 흉고직경을 나타내며, 압축, 휨, 경도, 전단, 충격강도 모두 우수하여 생장과 재질면을 고려했을 때 현시점에서 가장 우수한 품종으로 판단된다.

Relationship between growth rate and wood quality was investigated by physical and mechanical properties with Quercus rubra (24 years old) from five different origin of apricot. In greenwood moisture content, sapwood had higher moisture content than heartwood, and there was difference among different origin of apricot. There were different specific gravity of wood among different origin of apricot. Compared with higher growth rate with higher specific gravity in sapwood, opposite trend was observed in heartwood. There were difference in shrinkage based on origin of apricot, and higher growth rate wood had higher shrinkage and T/R ratio. Compression Young's modulus, bending strength, bending Young's modulus, and compact strength was difference among different origin of apricot. Higher growth rate wood had higher tensile strength, and also there was difference amont different origin of apricot. In hardness, 3 different directions had all difference among different origin of apricot, and higher growth rate wood showed higher hardness than others. Based on overall physical and/or mechanical properties and growth rate, apricot from Bancroft was best quality in current.
