초록
본 연구에서는 기능성 약용식물로 부가가치가 높은 두릅나무 선발클론을 대상으로 잎, 가시 그리고 동아의 형태적특정을 조사하고 다변량 분석 방법을 통하여 선발클론 간유연관계를 분석하였다. 주성분 분석 결과, 제4 주성분까지의 누적 기여율은 76%로 나타났으며, 유집분석 결과 거리 수준 2.0을 기준으로 Ⅰ그룹은 강원 연곡 등 15클론, Ⅱ그룹은 경기 여주 등 5클론, Ⅲ그룹은 봉화와 울릉 클론,Ⅳ그룹은 용문과 보성 클론 그리고 Ⅴ그룹은 신구 클론으로 총 5개 그룹으로 구분되었다.
Abstract
Aralia elata Seem. have a typical traditional significance among the wild herbs traditionally. Edible shoots of A. elata will augment consumer's interest due to its high value functional value, eco-friendly and pesticide-free produce. A. elata’s root, fruit and bark are used as material of hypoglycemic agent and medicine for diabetes, kidney trouble, acutehepatitis, rheumation arthritis, stomach cancer and gastroenteric trouble. Flavonoid glycoside compound which is separatedfrom A. elata's shoot shows high antioxidative activity. Also, root's identified active materials of antimicrobial was reportedto be produced as food preservative and handy antimicrobial. Therefore, this research investigated quantitativemorphological characteristics of leaves, spine and bud in naturally dominated and introducted A. elata in south Korea andthen considered its principal compound analysis(PCA) and classification analysis(CA) among the 6 improved cultivars and19 clones. PCA results showed that it show 76% accumulated explanation from four PC. The A. elata clones were classifiedinto five groups; the first group of 15 clones including Yeongok, the second group of 5 clones including Yeoju, the thirdgroup of Bonghwa, Ulleung, the fourth group of Yongmunsa, Boseong and the fifth group of Singu. The object of this studywill give us invaluable information about breeding by selection of A. elata in south Korea.
