영문 초록

This research was carried out to investigate the fundamental properties such as the structure of annual ring, density distribution, compressive strength with parallel to grain, relative crystallinity, and microfibril angle of Gumgangsong(Pinus densoflora for. erecta Uyeki). The wood specimens, Gumgangsong and Sonamu(Pinus densiflora S. et Z.), for this experiment were prepared at Uljingoon Sokwangri and Kyungpook university s forest in Kyungpook province, respectively. Average annual ring width is 2.0mm±0.3 in heartwood of Gumgangsong. The percentage of heart wood was over 60 percent in Gwngangsong and 20- 50 percent in Sonamu. HeartWood density were ranged from 0.5 to 0.8 g/cm² in Gumgangsong and from 0.4 to 0.5 g/cm² in Sonamu. Compressive strength in Gumgangsong and Sonamu was about 30:t5M1b and 25:t5M1b, resepectively. But the relative crystallinity and microfibril angle of two species were not different clearly. From these results of Gumgangsong and Sonamu, therefore, it was considered the main difference factors for both species were annual ring width and heartwood percentage.
