Background : With the recent increase in the area of ginseng cultivation in greenhouses, demand for studies of proper cropping patterns in direct seedling of ginseng and varieties of cultivation are increasing, and the needs for clean production of quality ginseng in greenhouses are emerging in connection with the consumer demand for pesticide-free ginseng and the supply and demand of ginseng seedling for cultivation of young ginseng. Therefore, this study is to provide baseline data in improving of quality of ginseng cultivated in greenhouses by examining the contents of ginsenoside in ginseng cultivated in different cropping patterns and different varieties. Methods and Results : As a result of examining the contents of ginsenoside in 3-year old, direct seedling ginseng cultivated in greenhouses in different depths – 10 ㎝, 20 ㎝ and 30 ㎝ - and width – 90 ㎝, 100 ㎝, 110 ㎝ and 120 ㎝ - of furrows, the contents of ginsenoside showed little differences by the depths of furrow in the furrow width of 90 ㎝ but, the highest content of ginsenoside Rb1 was observed in the furrow width of 120 ㎝ and depth of 20 ㎝, while the ginsenoside contents were high in the furrow depth of 20 ㎝ and width of 100 ㎝ and 120 ㎝. The contents of ginsenoside in different varieties of direct seedling cultivation in greenhouses were greater in the following order: Geumgin > Geumsun > Chunpoong, while the contents of ginsenoside Rb1 were observed to be superior in Sunhyang, Gopoong and Geumseon and the contents of ginsenoside Rb2 were greater in the order of Geumgin > Guemsun >　Cheonpoong. Conclusion : Based on the results, the contents of ginsenoside in different cropping patterns of direct seedling cultivation in greenhouses were higher in lower depths of furrow - 10 ㎝ and 20 ㎝ - at furrow widths wider than 100 ㎝. The contents of ginsenoside in different varieties of direct seedling cultivation in greenhouses were higher in varieties of Geumjin, Geumsun and Chunpoong.

Background : In recent years, as the ginseng cultivation area using vinyl house is increasing, the demand of farmhouses for the studies of appropriate direct sowing cultivation and ginseng varieties for vinyl house cultivation is increasing, and there is a necessity to produce high quality clean ginseng in vinyl house in tandem with the consumers’ demand for pesticide-free ginseng. Thus, the goal of this research is to determine appropriate ridge height and width when growing ginseng in the vinyl house using direct sowing cropping system. The research was also done to choose ginseng breed for direct sowing cultivation. Methods and Results : The ground part of 4 years old ginseng grown in the vinyl house using direct-sowing cropping pattern was the type that grew well in 100 ㎝ wide ridge rather than 90 ㎝ wide ridge. It also tended to grow well in 20 ㎝ or 30 ㎝ long ridge as opposed to 10 ㎝ long ones. The root weight of the underground part was superior under 90 ㎝ × 20 ㎝(ridge height×ridge width), 90 ㎝ × 30 ㎝, 110 ㎝ × 10 ㎝ and 110 ㎝ × 20 ㎝ cultivation area. The root diameter was longer, the longer the ridge height. The volume per 1.62 ㎡ was superior for 100cm, 120 ㎝ × 10 ㎝ cultivation area. The ginseng whose ground part was superior in the vinyl house were Chungsun and Seonweon. Seonweon and Gumpoong had superior root weight in underground parts. The root length was superior for Geumsun. The ginseng that were direct sowing in the vinyl house did not have rusty ginseng problem regardless of ridge height and kind. The root injury was greatest in the cultivation area with ridge width of 90 ㎝. Conclusion : According to the results above, the growth in vinyl house using direct sowing cropping pattern was best when ridge width was 100㎝ and 110cm in ridge height of 30 ㎝. The best selection was Chunpoong and Seonweon. The root weight of the underground part was superior in 110 ㎝ × 10 ㎝ cultivation area, the best variety was Seonweon and Gumpoong.

Background : In recent years, as the ginseng cultivation area using vinyl house is increasing, the demand of farmhouses for the studies of appropriate direct seeding cultivation and ginseng varieties for vinyl house cultivation is increasing, and there is a necessity to produce high quality clean ginseng in vinyl house in tandem with the consumers’ demand for pesticide-free ginseng and the supply-demand of ginseng seedling for sprout ginseng. Thus, the authors of this study analyzed the change of photosynthetic properties according to the cropping pattern and varieties with the aim to use the results of this study as the primary date for improving the quality of ginseng cultivated in vinyl house. Methods and Results : The authors analyzed the change of photosynthetic properties for the 3-year old ginseng cultivated through direct seeding according to the ginseng field levee height (10, 20, 30cm) and width (90, 100, 110, 120cm). The results suggested that with an increase in light intensity, the photosynthesis tends to increase regardless of levee height and width. When the levee width was 90cm, the photosynthesis increased as the levee height was reduced and it increased as the levee height increased when the levee width was 100cm. The photosynthesis was high when the levee height was 20cm for the levee width of 110cm and 120cm. The photosynthesis was analyzed for 11 varieties of 3-year old ginseng cultivated through direct seeding. The results suggested that the photosynthesis tends to increase as the light intensity increased in all 11 varieties, and the photosynthesis was the highest at 500PAR(ray source: 3.23umolCO2m-2s-1㎛ol) in the order of Cheonpoong, Yeonpoong, Cheongson and Sonwoon. Conclusion : The results of this study suggested that the photosynthesis according to the direct seeding cultivation in vinyl house increased as the levee height decreased for the levee width of 90cm and it was high when the levee height was 20cm for the levee width of 120cm. For the ginseng variety, Sonwon and Cheonpoong showed the highest photosynthesis.

본 연구는 남부지역에서 생력재배로 일시수확 및 관행재배로 생산한 녹두의 품질을 구명하고자 수행하였으며 결과는 다음과 같다. 생력재배는 7월 23일에 파종하여 10월 28일 일시에 수확하였고, 관행재배는 6월 13일에 파종하여 8월 중순부터 3차례 손으로 수확하였다. 1. 종실의 전분, 조단백질, vitexin 및 isovitexin 함량은 재배방식과 수확기에 따른 유의차가 없었다. 종실의 조지방 함량은 생력재배, 관행재배 3차, 2차, 1차 수확한 종실 순으로 많았다. 2. 종실의 포화지방산과 불포화지방산의 조성비는 재배방식 및 수확기에 따른 차이가 없었다. 지방산 종류는 관행재배로 2차 수확한 종실에서 17종으로 가장 많았고, 관행재배 3차나 생력재배로 일시에 수확한 종실은 12종으로 가장 적었다. 주요 포화지방산 중에서 palmitic acid와 arachidic acid는 관행재배 1차, 2차, 3차 및 생력재배 수확 순으로 높은 비율인 반면 stearic acid는 반대의 경향이었다. 주요 불포화지방산 중에서 linoleic acid는 관행재배 1차, 2차, 3차 수확 및 생력재배 순으로 조성 비율이 높았다. 3. 종실의 아밀로그램 특성은 재배방식 및 수확기에 따라 큰 차이를 나타냈다. 관행재배로 1차에 수확한 종실은 호화개시온도, 최고점도, 최종점도, 최저점도 및 강하점도가, 관행재배 3차에 수확한 종실은 치반점도가 유의하게 높았다. 반면에 생력재배로 수확된 종실은 모든 아밀로그램 측정값이 현저하게 낮았다. 4. 녹두나물을 생산하고 나물의 수율과 색도 및 아미노산 함량을 측정한 결과, 생력재배로 생산한 녹두는 나물의 생산수율이 낮으나 색도와 아미노산 함량은 관행재배로 수확한 종실을 이용하여 생산한 나물과 비슷하였다.
