        2007년에 도입된 인삼 임의자조금제도가 앞으로 범 인삼업 계가 참여하는 의무자조금제도로 전환될 예정이다. 인삼 의무 자조금의 성공적인 조성과 운용을 위해서는 자조금 거출액을 합리적인 수준으로 책정하고 인삼 농가들의 자발적인 참여를 유도하는 것이 필요하다. 본 연구에서는 이중양분선택형 조건 부가치평가법(CVM)을 이용하여 인삼 의무자조금에 대한 농 가의 지불의사액을 추정하였으며, 주요 결과 및 시사점은 다 음과 같다. 1. 인삼 의무자조금에 대한 농가 지불의사액(WTP)의 평균 값(Mean WTP)과 중앙값(Median WTP)은 각각 117.27원/kg 과 86.81원/kg으로 추정되었다. 따라서 인삼 대표자 그룹회의 에서 논의된 인삼 의무자조금 거출액인 100원/kg 수준이 무난 한 것으로 판단된다. 2. 인구통계학적 변수가 인삼 의무자조금 납부에 미치는 영 향을 검증한 결과 자조금에 대한 인지도가 높을수록, 그리고 교육수준이 높을수록 인삼 자조금을 납부할 확률이 높아지는 것으로 나타났다. 3. 기존에 인삼 임의자조금을 납부해온 농가일수록 의무자 조금을 납부할 확률이 낮아지는 것으로 나타났는데, 이러한 결 과는 인삼 자조금의 경제적 효과에 대한 회의적인 태도에서 비롯된다. 따라서 향후 인삼 의무자조금사업의 성공적인 안착 을 위해서는 인삼 농가들을 대상으로 자조금의 도입 취지, 필 요성, 경제적 효과 등에 대해 보다 확실히 인식시킴으로써 자 발적인 참여를 유도하는 것이 필요하다.

        뱀딸기 추출물의 항산화, 항염, 항암활성을 검정한 결과는 다음과 같다. ·뱀딸기(D. chrysantha) 부위별 항산화활성을 비교해본 결과 전초 > 지상부 > 열매의 순으로 전초가 Ascorbic acid(34.72μg/ml)보다 높은 활성을 나타냈으며, 열매가 가장 낮게 나타났다. ·항염활성은 전초 > 지상부 > 열매의 순으로 항산화활성과 유사한 경향을 보였다. ·항암활성은 인체 자궁경부암세포 HeLa에 대해서 열매가 가장 높게 나타났으며, 전초는 낮게 나타났다. 간암세포 SKHep1에 대해서 지상부와 전초가 비슷한 활성으로 열매보다는 높게 나타났으나 전체적으로 낮은 활성을 나타내었다.

        Angelica gigas, also called Dang Gui or Korean Angelica, is a major medicinal herb used in Asian countries such as Korea, Japan and China. In Korea, we are using the roots of A. gigas., but, they are using Angelica sinensis in China and using Angelica acutiloba. in Japan to obtain many active constituents such as dercursin, decursinol angelate, nodakenetin, nodakenin, umbelliferone, β-sisterol, or α-pinene. The plants of the Angelica family are used to improve gynecological health. The biggest problem in the cultivation of A. gigas is bolting. If the bolting occurs, A. gigas can not be used as a medicinal component because the roots are lignified. In this study, 11 A. gigas genetic resources in Korea; 1. Hwangje variety, 2. Sungwoo Jongmyo company, 3. Bonghwa No. 1, 4. Bonghwa No. 2, 5. Bonghwa No. 3, 6. Bonghwa No. 4, 7. Jechun local variety, 8. Jirisan local variety, 9. Manchu variety in Eumseong, 10. Manchu variety in Bonghwa, 11. Jinbu local variety, were collected and performed phylogenetic analysis using RAPD molecular markers.

        Adenophora triphylla var. japonica HARA is a herbaceous plant belongs to Campanulaceae. Adenophora root is mainly used for medicinal purpose. It is effective for lung cleaning, sputum remove, viscera strengthening, cough stopping and cancer treatments. Adenophora has about 70 species in the world and 17 of the species are distributed in Korea. Genetic resources of A. triphylla var. japonica HARA are valuable as the habitat is concentrated in East Asia. The intraspecies variation is very high according to the environmental conditions. A new A. triphylla var. japonica HARA variety, ‘Harang’, was developed through polyploid breeding in 2011. But, low domestic production and passive studies caused our country to rely on imports for almost all amount of the A. triphylla var. japonica HARA demands. In this experiment, genetic diversity between the collections were analyzed using 32 RAPD primers. Through this study, limit of morphologic classification could be solved and genetic diversity of this plant could be assured.

        Codonopsis lanceolata is used as a natural medicine or vegetables. It originates in East Asia such as Korea, Japan and China. Similar to Panax ginseng, C. lanceolata contains saponins as effective components. C. lanceolata is cultivated in many regions of South Korea. But, no variety was developed yet and the origin discrimination in the distribution market of C. lanceolata became a problem. In this study, we collected 20 C. lanceolata regional groups; Hoengseong, Wonju, Samcheok, Chuncheon, Pyeongchang, Hongcheon, Yongin, Yangpyeong, Danyang, Chungju, Bonghwa, Ulleung, Yeongju, Sancheong, Muju, Gwangyang, Sinan, Hwasun, Jeju-si and Seogwipo-si, and tested the genetic relationship using RAPD molecular markers. The genomic DNA was extracted using CTAB and the RAPD analysis was performed using 32 primers of Operon Technologies. NTsys-PC program was used for the phylogenetic analysis of the data.

        Senna tora (L.) Roxb. belongs to Leguminosae and its seeds are usually roasted and boiled in water to produce tea in Korea. Also the plants are well known for the treatment of Hypertension, Hepatitis, Constipation and Conjunctivitis. This study was conducted to investigate the morphological characteristics and pollen germination rates of Senna tora with the aim of genetic mapping of this species. First, we investigated morphological characteristics of domestic and international genotypes containing 51 lines in Korea and 2 lines in China. No significant differences in growth characteristics were observed among 53 genotypes. However, ST-9 line which was collected in Pyung-chang showed high growth rate at the early stage. The flower of Senna tora consists of 5 petals, 10 surgeries (7 main surgeries, 3 small surgeries), 1 pistil, and 5 sepals. After bud emergence, each petal was white in 1-2 days, turn into ivory in a week, then yellow in 8-9 days and finally bloomed in 9-10 days. Although the average flowering times of the plants were July 24, ST9 flowered in July 12. In addition, the flowers of ST9 differed from the flowers of the other genotypes. Flower of ST9 joined together with one another. Therefore, ST9 showing high growth rate at the early stage and unique flowering characteristics was selected to as the paternal line for genetic mapping study. Second, we investigated pollen germination rates for each stage of flower development. Pollen started to germinate at the yellow bud stage and pollen germination rate was highest in the bloomed flower stage. This results show that self-fertilization hardly occurs when the flower is ivory bud stage, and there is no need to use young bud flowers for artificial crossing. This work is intended to serve as the basis for the breeding of new varieties in Senna tora.
