The effect of the surrounding vegetation on the seed germination and growth of mountain-cultivated ginseng (MCG, Panax ginseng C.A. Meyer) was investigated. Seed germination rate and growth were tested for allelopathy effects on four forest tree species after treatment with fallen leaves and leaf extracts. In the case of soil treatment through fallen leaves and crushed leaves, the germination rate was lower in the Quercus myrsinifolia treatments, and the average germination time was slower when Chamaecyparis obtusa was treated. In the case of Pinus densiflora and Quercus variabilis, which are used in most of the MCG cultivation areas, they did not have a significant effect on seed germination. In the fallen leaves treatments, the stem showed a tendency to lengthen. The hot water extract treatment showed a higher germination percentage than the cold water extract treatment. The extract treatment showed a deficient germination percentage of some MCG seeds. However, in the case of the treatments except for this, the germination percentage was similar to that of the control treatment. However, the Mean Germination Time, germination rate, and germination value were faster and higher than the control treatment. As a result of calculating the allelopathic index (AI) of MCG according to the extract treatment of 4 species, most had a negative effect on germination, and P. densiflora and Q. variabilis extracts showed the most significant effect. The ginsenoside content was higher in the fallen leaves treatment than in the control. The above results will help select and manage MCG plantations.

This study conducts a comparative analysis on the difference in profitability between organically cultivated ginseng and conventionally cultivated ginseng, based on their cultivation characteristics, in order to promote the production and consumption of organic ginseng. The production quantity of organically cultivated ginseng per 10 a was 40% less than that of conventionally cultivated ginseng for both four- and six-year-old roots. In the case of four-year-old roots, although the production cost of organically cultivated ginseng was 60% higher than that of conventionally cultivated ginseng, the net profit was higher by 70%, owing to its higher selling price. In the case of six-year-old roots, the production cost of organically cultivated ginseng was 10% higher than that of conventionally cultivated ginseng, but the net profit was lower by 10%, owing to a low selling price. The reduction in production costs must be supported by a reduction in land lease and labor costs by expanding the cultivation area, a reduction of pest control costs through the self-production of environmentally friendly materials, and an improvement in the certification of perennial crops that can reduce certification costs. A reduction in production costs can lead to a decrease in consumer prices, which, in turn, would promote an increase in consumption among general consumers. Moreover, as a measure to increase the production yield per unit area, the soil nutrient content must be increased by selecting high-quality planned sites and implementing planned site management in order to increase the proportion of organic fertilizers. Furthermore, these must be supported by improved cultivation methods, which suppress early defoliation, and enhanced cultivation technology. In addition to these methods, establishing producer cooperatives in order to expand production can stabilize supply, which can increase sales through export and processing companies. Moreover, uniformity in product quality through producer cooperatives can contribute to building consumer confidence.

생체 내 실험에서 발효 인삼꽃 추출물(FM), 발효하지 않은 인삼꽃 추출물(FD)과 대조군으로 생리식염수를 2주간 마우스 체중 ㎏ 당 100, 200 ㎎/㎏ B.W.의 농도로 마우스에 경구 투여한 후 LPS에 의해 활성화된 복강 대식세포가 분비하는 염증성 사이토카인 IL-6, TNF-α의 생성량을 측정하였다. 그 결과, IL-6는 발효 LPS로 자극한 경우, 두 가지 농도에서 모두 처리한 군에 비해 높은 증식능을 나타내었고, LPS로 자극한 결과, 특히 발효 인삼꽃 추출물 200 ㎎/㎏ B.W. 농도에서 유의적으로 낮은 IL-6 분비량을 보였다. TNF-α의 경우, 100 ㎎/㎏ B.W.와 200 ㎎/㎏ B.W. 두 농도 모두에서 LPS로 자극하지 않은 경우, 낮은 증식 효과를 보여주었고, 자극한 경우, 인삼꽃 시료를 첨가한 군이 대조군보다 낮은 TNF-α 분비량을 보였으며, FM에서 FD보다 더 TNF-α를 억제하는 효과가 큰 것을 볼 수 있었다. 이상의 결과에 따르면 FD의 사이토카인 IL-6, TNF-α 생성 효과는 200 ㎎/㎏ B.W. 농도 투여 시 효과적으로 면역 세포와 면역 기관의 주요 기능을 증진시킬 가능성이 있을 것으로 사료된다. 이러한 연구결과를 토대로 앞으로 인삼꽃 발효를 이용한 기능성 사료 개발과 더불어 산업적 측면에서 보다 긍정적인 효과를 얻을 수 있을 것으로 판단된다.
