본 연구는 희귀식물 가침박달의 실생묘를 이용한 현지외 보존시 집단 선정과 개체 선발 방법에 따른 유전적 다양성의 차이를 비교하여 효율적인 선발 전략을 구명하는데 그 목적이 있다. 우리나라에 분포하는 7개 집단을 대상으로 자연집단과 차대집단의 유전다양성을 평가하였다. 7개 차대집단의 종수준의 유전다양성( S.I .=0.505)은 자연집단( S.I .=0.536)의 94%로 나타났다. 가침박달의 자연집단은 선행 연구에서 유전적 특성에 따라 크게 3개의 지역으로 구분되었다. 지역별로 가장 유전다양성이 높은 3개의 집단(대구, 청주, 단양)에 대해 종 수준의 유전다양성을 분석한 결과 0.493으로 자연집단의 92%로 높게 나타났다. 따라서 7개 집단을 선정하는 것과 3개 집단을 선정하는 것 모두 자연집단의 유전다양성 90% 이상을 보존하는 것으로 나타났으며 3개 집단을 보존하는 것이 효율적인 것으로 판단되었다. 3개집단을 대상으로 집단별 개체 선발 개수에 따른 유전다양성의 변화를 살펴본 결과, 집단별 34개체씩 총 102개체 이상을 선정할 경우 자연집단의 92%의 유전변이를 확보하는 것으로 나타났다. 따라서, 가침박달의 현지외 보존시 3개 집단(대구, 청주, 단양)을 대상으로 집단별 34개체 이상을 선정하여 보전하는 것이 효과적인 것으로 나타났다. This study was conducted to study effective seedling sampling strategies for ex situ conservation of Exochorda serratifolia S. Moore based on the result of change in genetic diversity with different selection methods of populations and individuals. Genetic diversity was estimated in seven cohorts of the natural populations and their progeny populations(seedlings) of E. sarratifolia in South Korea. The ratio of genetic diversity at the species level in progeny populations was 94 percentage of the genetic diversity of the natural populations. On the results of previous study, the natural populations were assigned into three groups. Three populations(Daegu, Cheongju, and Danyang), which have the highest genetic diversity in each group, showed a 92 percentage of the genetic diversity of the natural populations at the species level. Both sampling methods were effective to maintain over 90 percentage of the genetic diversity of the natural populations, therefore it was suggested that selecting three populations more efficient. For three populations, if more than 34 individuals(total 102 individuals) were selected in each population, which would be expected to maintain 92 percentage of the genetic variation of the natural populations. Thus it was effective to select 3 populations and more than 34 individuals in each population for ex situ conservation of E. serratifolia.

본 연구는 팥배나무의 열매에 대한 우수개체 선발을 위한 기초자료를 얻고자 11개 집단에서 총 107개체를 선발하여 선발목 열매의 형태적 특성 변이를 조사하고 주성분 분석과 군집분석을 실시하였으며 열매 특성에 의한 선발효과를 추정하였다. 주성분 분석 결과, 제4 주성분까지 75.4%의 설명력을 나타냈으며 군집분석에서는 4 그룹으로 구분되어짐을 알 수 있었다. 열매 수확량과 관련된 특성인 열매 폭과 길이 그리고 송이 당 수확량 특성을 대상으로 광교산1, 2와 덕유산7 그리고 마니산 29, 30 등 5개체의 우수개체 후보목을 선발하였다. 선발개체 5본에 대해서 전체 평균 형질과 비교하여 선발효과를 추정한 결과, 열매 폭은 122.8%, 열매 길이는 115.5%, 송이 당 수확량은 182.7%의 선발효과를 추정할 수 있었다. In order to select superior trees based on fruit characteristics and provide basic informations necessary for their improvement, total 107 individual trees of Sorbus alnifolia (Sieb. et Zucc.) K. Koch were selected from 11 wild populations in South Korea. After collecting normal fruit branch, we investigated morphological characteristics of fruit and then considered its relationship among the 11 populations by multivariate analysis method. Results from principal compound analysis showed that it represented 85.8% accumulated explanation from five principal compounds. According to cluster analysis based on fruit characteristics, the natural S. alnifolia populations were classified into four groups and Mt. Mani population was different from other populations. Selection effect with outstanding candidate trees including superior 5 individual trees (Gwangyo 1, Gwangyo 2, Deogyu 7, Mani 29, Mani 30) was estimated at 122.8%, 115.5% and 182.7% in fruit width, length and yield per fruit bunch, respectively. The object of this results will give us invaluable information about breeding by selection of S. alnifolia in south Korea.

To compare varietal differences in Rubus coreanus Miq. (Rosaceae), we evaluated antioxidant activity and the contents of functional substances. In this study, five new cultivars selected as superior berries in yield and weight of fruit, R. coreanus (Jungkeuam 1, 2, 3, 4, and 5), and one foreign berry, R. fructicosus were used. The contents of the major anthocyanin, cyanidin-3-glucoside(C3G) in berries and antioxidant capacity including, free radical scavenging activity and reducing power were measured. The contents of total phenol and vitamin C were also investigated. Among 5 cultivars and one foreign berry, Jungkeuam 1 had the richest C3G and high levels in vitamin C. DPPH radical scavenging activity of berries was ranged from 46.58 up to 78.55%.

Hovenia dulcis var. koreana Nakai has been reported to liver function improvement effect as functional materials for food and medicine. On these facts, biological activity and safety test were conducted to evaluate biological activities of the fruit petiole and root extracts of H. dulcis as a potential cosmeceutical ingredient. Cosmeceutica activities of different extracts were examined by l.l-diphenyl-2-picrylhydrazyl (DPPH) radical generation, the ABTS+ cation decolorization, tyrosinase activity, collagenase activity and elastase activity compared with the properties of the commercial antioxidant butylated hydroxytoluene (BHT) and L-ascorbic acid(AA). The antioxidant activities HDFW, HDFE, HDRW and HDRE were 83.6%, 39.6%, 85.9% and 74.5% in DPPH assay, 99.5%, 13.7%, 96.4% and 88.6% in ABTS assay. Tyrosinase inhibitiory activities HDFW were 56.0% at 1,000 ppm. Measured the inhibition effect of the H. dulcis about collagenase and elastase where break the peptide bonds in collagen and enzyme from the class of proteases where exists in the dermis. The H. dulcis was inhibition the two kind enzymesm, collagenase activities being on a high scale inhibition, was same concentration. Uses the anti oxidation effect and a anti-wrinkle effect of this resultant H. dulcis and with the functional cosmetics use is thought with the fact that will be possible.
