울진 금강송재의 재질: 수지구 및 방사조직의 출현형태 = Property of Uljin-Geumgangsong Wood (Pinus densiflora forma erecta Uyeki): Appearance Pattern of Resin Canal and Ray

다국어 초록 (Multilingual Abstract)

It was examined the key criterion of the time of property revelation as Uljin-Geumgangsong wood. For this purpose, we investigated in physical properties in pine wood (Pinus densiflora Sieb. et Zucc.) and representative Uljin- Geumgangsong wood (Pinus densiflora forma erecta Uyeki). The results are as follows; Air-dry density of Uljin- Geumgangsong wood have higher values over about 20 percent than that of pine wood. And also heartwood rate of Uljin-Geumgansong wood have higher values above 70 percent. The number of vertical resin canals per 1 mm2 in Uljin-Geumgangsong wood was 40 percent greater than in pine wood. As the average diameters of axial resin canals were 67.8 mm and 67.3~69.9 mm in pine wood and in Uljin-Geumgangsong wood, respectively, there was no significant difference among wood species. There tends to be an increase in diameters as annual rings increase. The number of horizontal resin canals in Uljin-Geumgangsong-1 was approximately 55 percent greater than in pine wood and Uljin-Geumgangsong-2. The number of resin canals in pine wood and Uljin-Geumgangson-2 decreased while it increased in Uljin-Geumgangsong-1 as annual rings increased. No significant difference was found in the number of rays among wood species and between earlywood and latewood of same wood species. As annual rings increased the number of rays decreased in both pine wood and Uljin-Geumgangsong. The heights of rays were greater in pine wood than Uljin-Geumgangsong and no difference was found between earlywood and latewood. In conclusion, rings of tree for the time of property revelation as Uljin-Geumgangsong wood is assumed about more than 150 years.
