Abstract

Physical characteristics of Korean red pine (Pinus densiflora) were investigated with different cultivation locations in Taebaek Mountains as Goseong-gun, Hongcheon-gun and Bonghwa-gun as experimental sites. Moisture content based on air-dried or green (artificial) wood was no significant differences with different cultivation places. Specific gravities of both sapwood and heartwood of red pine from Bonghwa-gun were higher than those from other two sites (Hongcheon-gun or Goseong-gun). Specific gravity of heartwood of red pine from Goseong-gun was higher than it from Hongcheon-gun, but this trend was opposite in case of sapwood. Higher specific gravity of red pine heartwood from Goseong-gun maybe resulted in higher strength than those of other sites. In shrinkage ratio, there was no significant difference among different cultivation places in radial directions, but red pine from Bonghwa-gun was higher than those of other sites in tangential directions. Hygroscopicity was no significant differences with different cultivation places. These results will be helpful information for efficient use of pinewood and good quality of pinewood production for genetical breeding improved.

본 연구는 태백산맥을 기준으로 영동(고성군), 영서(홍천군), 영남(봉화군) 세 지역 간 소나무의 재질차이의 유무를 알기위해 물리적 특성을 조사하였다. 기건함수율 및 생재함수율(인위적)의 산지 간 차이를 보이지 않았다. 비중은 심재부와 변재부에서 봉화군 소나무가 두 산지보다 높았으며, 고성군과 홍천군 소나무 사이에는 심재부에서는 고성군 소나무가 높고 변재부에서는 홍천군 소나무가 고성군 소나무 보다 높게 나타났다. 심재부의 비중이 높게 나타난 고성군 소나무가 강도적으로 홍천군 소나무보다 클 것으로 판단된다. 수축율은 방사방향의 경우 산지 간 차이가 없고, 접선방향의 경우는 가도관장이 긴 봉화군 소나무가 높게 나타났다. 흡습율은 산지 간 차이가 거의 없는 것으로 나타났다. 이 결과로 소나무를 효율적으로 사용할 수 있고, 육종적으로 좋은 재질의 품종생산에도 도움이 될 것으로 생각한다.
