On the growth of Pinus Thunbergii

곰솔 성장(成長)에 대(對)하여

The growth of Pinus Thunbergii in the four areas was compared with each other, and the results obtained are as follows ; 1. The diameter growth in HAP-CHUN area was found the best, and that of WOOI-SAN, CHE-JU, and SUWON areas was followed in order. 2. The height growth was found the best in WOOI-SAN area, and followed SUWON, HAP-CHUN, and CHE-JU areas in order. 3. The volume growth was found the best in HAP-CHUN area, followed next in order were : WOOL-SAN CHE-JU, and SUWON. 4. Based on the above-mentioned results, it was concluded that the growth of Pinus Thunbergii in inland areas was better than that in islands or coastal areas. This is against the common understanding that Pinus Thunbergii species grow better in coastal areas.

4개지역(個地域)에서 생육(生育)하고 있는 곰솔의 성장비교(成長比較)을 하였는데 그 결과(結果)는 다음과 같다. (1) 직경성장(直徑成長)이 가장 양호(良好)한 곳은 합천(陜川)이고 다음이 울산(蔚山), 제주(濟州), 수원(水原)의 순위(順位)였다. (2) 수고성장(樹高成長)이 가장 양호(良好)한 순위(順位)을 보면 울산(蔚山), 수원(水原), 합천(陜川), 제주(濟州) 순(順)이다. (3) 재적성장(材積成長)이 가장 양호(良好)한 순위(順位)을 보면 합천(陜川), 울산(蔚山), 제주(濟州), 수원(水原)으로 되어있다. (4) 위의 것으로 미루어 볼 때 곰솔이 해안수종(海岸樹種)으로 알려져 있으나 성장(成長)은 내륙지방(內陸地方)이 도리어 도서지방(島嶼地方) 또는 해안지방(海岸地方)보다 양호(良好)하였다.
