한국농수산대학교 공정육묘실에서 인삼을 종자 파종하여 생장한 인삼 1년근을 각 실험구(공정육묘실, 관행 노지)에 이식 전 1차 생장 조사를 하고, 3개월 생육 후 2차 생장 비교조사를 하였다. 1차 생장 조사 결과, 이식 전 뿌리의 무게는 평균 0.95g에서 이식 후 관행 노지는 0.21g, 공정육묘실은 0.29g으로 증가하였다. 뿌리의 길이는 평균 13.85cm에서 이식 후 관행 노지는 2.03cm, 공정육묘실은 2.66cm로 증가하였다. 뿌리의 지름은 평균 5.58mm에서 이식 후 관행 노지는 1.04mm, 공정육묘실은 1.26mm로 증가하였다. 공정육묘실에서 생육한 인삼이 관행 노지재배보다 더 많은 생장이 확인되었다. 공정육묘실에서 생육한 인삼과 진안 농가 관행 노지재배 인삼의 진세노사이드 성분함량 비교를 위해 각 1년근, 2년근의 진세노사이드 11종(Rg1, Re, Rf, Rh1(S)+Rg2(S), Rb1, Rc, Ra1, Rb2, Rb3, Rd, Rg3)의 함량 비교한 결과, 진세노사이드 1종 전체 함량이 공정육묘실 재배 인삼 1년근에서는 17.32mg/g, 공정육묘실 재배 인삼 2년근에서는 16.43mg/g, 관행 노지재배 1년근에서는 5.84mg/g, 관행 노지재배 2년근에서는 6.17mg/g으로 확인되었다. 관행 노지재배 인삼 1년근, 2년근보다 공정육묘실 1년근, 2년근이 2배 이상으로 더 많은 진세노사이드 함량이 HPLC 분석 결괏값으로 확인되었다. 결론적으로 관행 노지재배 묘삼은 자연환경 아래에서 재배환경의 다양한 요인에 의한 생장이 작용하는 반면 공정육묘는 생장이 우수한 인공토 비율과, 식물 영양액 농도 EC1.0ms/cm로 수분을 공급하여 안정된 생장을 할 수 있고, 식물 생장에 필요한 온도, 광, 수분의 환경제어가 가능한 상태에서 생장하므로 묘삼의 생장 안정성을 확보할 수 있어 향후 이에 관한 지속적인 연구가 필요하다. This study conducted an experiment with EC 1.0ms/cm ratio and excellent soil conditions for germination in ICT-based ginseng process cultivation. The first growth survey was conducted before transplantation of ginseng 1-year roots grown by seeding ginseng in the process cultivation, conventional cultivation and a second growth comparison survey was conducted after 3 months of growth. In the results, it was confirmed that ginseng grown in the process cultivation grew more than in the field. As a result of comparing the contents of 11 ginsenosides of 1-year and 2-year-old ginsenosides in the process cultivation and conventional cultivation ginseng, it was confirmed that the content of the process cultivation ginseng was higher than that of practice cultivation ginseng. In conclusion, conventional cultivation ginseng grows due to various factors under the natural cultivation environment, but process cultivation can secure the growth stability of ginseng by allowing stable soil and environmental control, so continuous research is needed in the future.

도입 마(Dioscorea alate L.) 계통 중 품질이 우수하고 이 용 가치가 기대되는 열대산 마(D. alata)를 우리나라에서 재배 시 그 가능성과 제 기관의 생육특성을 밝히기 위하여 실시하였다 D. alata. 및 D. opposita의 생육패턴 및 수량성을 비교 도입 재배 가능성을 시험하였다. 1. 4월 하순에 정식한 마의 지상부는 70일까지는 완만한 생육을 보였으나, 그후에 급격히 생장하여, 200일 이후 지상부의 하부가 낙엽지며 감소하였다. 생육은 D. atara, 단마 순이였다. 2. 도입마(D. alate)의 형성은 정식 50일 정도에서 일어났으나, 그 후 비대생장이 늦어서 150일 이후에 급격 히 비대하였다. 3. D. alata(도입마)의 일반성분은 D. opposita(단가) 보다 단백질, 섬유, 지방의 함량이 낮았다. 4. D. alata의 경도를 보면 2696.2로 D. opposita 4946.9 보다 약 2배정도 낮고, 색도 중 명도(L)는 D. alata가 73.99으로 D. opposite 보다 높았다. This study was carried out to determine agronomic and genetic characteristics of the production process in tropical yams(Dioscorea atata L.). To make clear the possibility of cultivation of tropical yams in the Suwon area, the growth of the aboveground parts and the enlargement of tuber of Dioscorea alata, were investigated. The aboveground parts of the plants whose sprouted mother tuber were planted in late April were grown slowly until the 70-days after planting and grown rapidly after. from about 150-days after plantation, total length of vines slowly decreased due to the burning of the branch vines of lower modes. With regard to the branching progressed to 4th for the solo yam and to 6th for purple yam. The secondary branches tended to grow better. When the formation of daughter tubers was observed at the 50-days after planting, their enlargement was very slow. The rapid growth of tubers began at the 140-days and continued to the 190-days. General components such as protein, fiber, and lipid were higher in D. opposita rather than in D. alata. Hardness of D. alata was 2696.2 while that of D. opposita was 4946.9. Lightness of D. alata was 73.99, being higher than that of D. opposita.
