Abstract

This experiment was conducted to investigate the propagation for mass production of Acanthopanax koreanum NAKAI utilized for health food and medicine material. Germination rate of A. koreanum seeds were 64% when seeds were stored at 15 for 60 days and then were treated with 50 ppm of kinetin and dormancy were broken at 5 for 60 days. Rooting rates of green-wood cuttings treated with IBA 100 ppm, NAA 50 ppm, and IAA 100 ppm were 61.7, 56.7, and 60.0%, respectively. Rooting rates of greenwood cuttings treated with Rooton in scoria + horticulture media and volcanic ash were 76.7 and 66.7%, respectively. Survival rate of seedlings planted on Aug. 10 was highest (96%) under 75% shading net while shoot growth was best under 55% shading net. Survival rate of seedlings planted on May 2 was highest (91%) 55% shading net, and shoot growth was also best 55% under shading net.

제주특산 식물인 섬오갈피나무(Acanthopanax koreanum NAKAI)의 다량증식을 위하여 번식방법 및 유묘 생육 상황을 조사한 결과는 다음과 같다. 1. 종자는 15 에서 60일간 후숙시킨 다음 Kinetin 50ppm에서 24시간 침지후 5 에서 60일간 저온처리 하여 휴면타파한 것이 발아율 64%였다. 2. 녹지삽에서 호르몬 농도처리시 발근율은 IBA 100ppm에서 61.7%, NAA 50ppm에서 56.7%, IAA 100ppm에서 60.0%였다. 3. 녹지삽목에서 상토재료별 루톤 분의 처리 시 발근율은 송이+원예상토에서 76.7%, 비화산회토양에서 66.7%로 효과적 이었다. 4. 3월 30일 삽목하여 8월 10일 정식묘에서 활착율은 75%, 차광망 설치구에서 96%로 좋았으며 지상부 생육상황은 55% 차광망 설치구에서 좋았다. 5. 9월 30일 삽목하여 다음해 5월 2일 정식묘에서 활착율은 55% 차광망 설치구에서 91%로 좋았으며, 생육 및 수량성은 55% 차광망 설치구에서 양호하였다. 6. 전정부위에 따른 줄기 재생력은 지상 30cm 높이에서 전정한 것이 생육이 좋았다.
