Abstract

This study identified Korean red pine (Pinus densiflora) and exotic pines (Pinus resinosa, Pinus sylvestris) with a similar anatomical structure using a dendro-anatomical method that applied dendrochronology, tracheid length, and uniseriate ray cell size. Korean red pine samples were collected from 13 national parks, while exotic pine samples were secured from two wood importers. Tracheid length was measured by distinguishing earlywood from latewood, and uniseriate ray height and cell number were determined. As the exotic pine tree-ring chronology was consistent with the foreign standard tree-ring chronology and displayed high statistical significance, the country and region where the pine samples had been felled and the exact felling date were confirmed. According to the results, which compared tracheid length and uniseriate ray size, no difference was observed between the Korean red and Russian pines. However, the tracheid length of the Russian pines turned out to be slightly longer than the length of the Korean red pine. Additional research securing a larger number of exotic pines (P.resinosa, P.sylvestris) is required to yield more accurate results in the future.

연륜연대기와 가도관 길이, 단열방사조직 크기를 이용하여 유사한 해부학적 구조를 가지는 국내산 소나무(Pinus densiflora)와 외래산 소나무(Pinus resinosa, Pinus sylvestris)를 연륜해부학적 방법으로 식별하고자 하였다. 조사를 위하여 13곳의 국립공원에서 국내산 소나무 시료를 채취하였고 외래산 소나무 시료는 목재수입업체 2곳에서 확보하였다. 가도관 길이 측정은 조재와 만재를 구분하여 실시하였고, 단열방사조직 높이와 구성 세포수를 측정하였다. 외래산 소나무로 제작된 연륜연대기는 외국의 표준연륜연대기와 통계적으로 유의성이 높아 벌채된 국가 및 지역, 정확한 벌채시기까지 확인할 수 있었다. 가도관 길이와 단열방사조직의 높이를 비교한 결과에서는 차이가 없는 것으로 확인되었고, 다만 러시아 소나무의 가도관이 국내산 소나무들보다는 다소 긴 것으로 나타내었다. 향후 다수의 외래산 소나무 시편을 확보하여 추가적인 연구가 진행된다면, 보다 정확한 결과가 제시될 수 있을 것으로 판단된다.
