Abstract

This study was conducted to analysis the growth characteristics and the diameter at breast height (10 cm) reached ages in natural stand and platation for the optimal planting density and planting timing of Acer mono for. rubripes. There was high correlation between the DBH and crown diameter (E-W: r=0.82, S-N: r=0.76) in natural stand, and between the DBH and crown diameter (E-W: r=0.76, S-N: r=0.90) in plantation. In natural stand, average reached age on DBH 10 cm was $21.1{\pm}7.0$, and was $9.2{\pm}1.3$ in plantation. Therefore, the collectable timing of sap in artificial planting short approximately 2.3 times over the natural regeneration.

붉은고로쇠나무의 적정 식재밀도와 대체조림수로서의 적정 조림시기를 위한 기초 자료를 제공하기 위해 천연림과 조림지에서 생장인자분석과 흉고직경 10 cm 도달연수를 측정하였다. 천연림에서 흉고직경은 수관폭과 높은 상관관계(E-W: r=0.82, S-N: r=0.76)를 나타내었고 조림지의 흉고직경과 수관폭도 높은 상관관계 (E-W: r=0.76, S-N: r=0.90)를 나타내었다. 천연림에서 흉고직경 10cm에 도달하는 평균연수는 $21.1{\pm}7.0$년, 조림지에서는 $9.2{\pm}1.3$년으로 측정되어 최초 수액채취가 가능한 시기는 인공조림시 천연갱신을 통해 형성된 자생지 보다 약 2.3배 단축되는 것으로 나타났다.
