본 연구는 산채을 활용한 어린잎 혼합 포장 상품의 개발하기 위해 기존 어린잎채소에 많이 사용되고 있는 어린잎 적로메인 상추(Lactuca sativa ‘Red romaine’)에 어린잎 산채로 갯기름 나물(Peucedanum japoincum Thunberg)과 곤달비(Ligularia stenocephala)을 혼합하여 적합한 비율을 알아보고자 수행하 였다. 적로메인과 산채의 혼합비율은 적로메인0 : 갯기름5 : 곤 달비5(R0:P5:L5), 적로메인3.3 : 갯기름3.3 : 곤달비3.3(R3.3: P3.3:L3.3), 적로메인5 : 갯기름2.5 : 곤달비2.5(R5:P2.5:L2.5), 적로메인8 : 갯기름1 : 곤달비1(R8:P1:L1), 적로메인10 : 갯기름0 : 곤달비0(R10:P0:L0)으로 처리하였다. 모든 처리구는 OTR(Oxygen transmission rate) 10,000cc·m -2 ·day -1 ·atm -1 필름으로 포장하여 2°C/85%RH 저온고에서 27일간 저장하며 생체중 감소율, 포장내 이산화탄소/산소/에틸렌 농도, 외관, 엽록소 함량, 색도를 조사하였다. 생체중은 R8:P1:L1 처리구가 0.4% 미만의 가장 낮은 감소율을 보였고, 이를 제외한 나머지 처리구들은 0.5% 내외의 수치를 나타내었으나 통계적 유의성은 없었다. 포장내 산소와 이산화탄소 농도는 작물의 호흡률에 영향을 받았는데, 호흡률이 낮았던 상추의 혼합 비율이 높아질수록 포장내 산소농도가 높았고, 이산화탄소 농도는 낮았다. 산소농도는 15일이후 크게 감소하였으나, 16%이상은 유지되었고, 이와 반대로 이산화탄소 농도의 경우 15일까지 1-4%로 유지되다가 서서히 증가하여 27일차에 는 2-5%로 증가하였다. 에틸렌 농도는 저장 종료일까지 3-6μL·L -1 내외의 농도를 유지하였다. 저장 종료일의 외관상 품질은 모든 처리구가 상품성 한계점인 3점에 다소 못 미치는 정도를 보였다. 엽록소 함량(SPAD)은 처리구간 통계적 유의성은 없었으나, 적로메인과 곤달비의 경우 R8:P1:L1 처리구에서, 갯기름나물은 R5:P2.5:L2.5과 R8:P1:L1처리구에서 가장 적게 감소하였다. Heat map으로 비교한 3가지 작물의 엽색(L * , a * , b * , chroma)은 R5:P2.5:L2.5와 R8:P1:L1 처리구에서 저장 후 가장 변화가 적었다. 이중 R8:P1:L1 처리구는 엽록 소 함량도 가장 높게 유지되었으며 포장내 에틸렌 농도도 2번째로 낮았고 이산화탄소 농도는 2-3% 수준을 유지하였다. 따라서 적로메인 8, 곤달비 1, 갯기름 1(R8:P1:L1)의 혼합한 비율이 이 3가지 작물의 어린잎 혼합 포장에 가장 적합한 것으로 판단된다.

This study was conducted to evaluate the growth conditions and vegetation of Peucedanum japonicum habitatin uninhabited islands of Incheon Korea. The emergence area of Peucedanum japonicum was 4.9m distance in coastline,and altitude and slope was 7.4m and 47.5%. Soil pH, organic matter and P2O5 of habitat were 7.1, 8.3% and 29.0㎎/㎏, andcontents of K, Ca, Mg and Na were 0.66, 4.9, 3.4 and 1.13cmol+/kg, respectively. Growth plants with Peucedanum japonicumwere total 55 taxa, and Gakeuldo in uninhabited islands was the most as 25 taxa. In growth plants with Peucedanumjaponicum, plants of over 25% frequence per plot were Miscanthus sinensis, Dendranthema boreale, Lilium lancifolium,Hemerocallis middendorffii, Elymus dahuricus, Cirsium japonicum var. maackii, Asparagus schoberioides, Gypsophila oldhamiana,Cocculus trilobus, Silene aprica var. oldhamiana, Artemisia capillaris, Crepidiastrum denticulatum and Sedum oryzifolium.The vegetation of Peucedanum japonicum habitat was classified into Aster spathulifolius community, Miscanthus sinensiscommunity, Dendranthema boreale community, Setaria viridis var. pachystachys community, Cirsium japonicum var. maackiicommunity and Hemerocallis middendorffii community. According to general condition of habitat, suitable growing areaswas determined to slightly acidic from mild alkaline soils.

This study was carried out in order to investigate the photosynthesis response and leaf characteristics of Peucedanum japonicum growing in forest farming. The experiment was performed by leaf mold (pine tree and chestnut tree) and shading levels (0%, 35%, 50% and 75% shading). Light relative intensity was 100% (full sunlight), 60.3% (35% shading), 35.1% (50% shading), and 17.4% (75% shading) respectively. Light response curves of pine-leaf mold and chestnut-leaf mold were the highest in control (full sunlight) and these were getting lower in the higher shading level. Photosynthesis capacity and light saturation point were indicated higher in chestnut-leaf mold within the same shading level. As the shading level increased, maximum photosynthesis rate decreased. And apparent quantum yield was not indicated statistically significant difference from all treatment. Leaf area, leaf length and leaf width were significant higher in 35% shading and control under chestnut-leaf mold in all treatment. As the shading level increased, LAR (leaf area ratio), SLA (specific leaf area) and SPAD value decreased in pine-leaf mold and chestnut-leaf mold. As a result of surveying the whole experiment, P. japonicum is judged better growth and higher yield by maintaining 35% shading (relative light intensity 60%) under chestnut-leaf mold in forest farming.

본 연구에서는 재배조건(하우스재배, 노지재배), 수확시기(어린잎, 성잎) 열처리에 따른 영양성분 및 항산화활성의 변화를 비교 분석하여 국가표준성분표 발간을 위한 기초자료로 활용하고자 하였다. 일반성분 4종(수분, 지질, 회분, 단백질), 무기질 5종(칼슘, 철, 마그네슘, 칼륨, 나트륨), 비타민 3종(비타민 C, 엽산, 베타카로틴)의 영양성분을 분석하였고 폴리페놀 화합물과 DPPH 라디칼 제거능을 각각 측정하였다. 연구결과 일반성분의 경우 시료 간에 유의적인 차이를 나타내지 않았으나 무기질의 경우 Ca, Mg, Na은 하우스 재배가 노지재배 보다 유의적으로 높은 함량을 나타내었다. 비타민함량과 폴리페놀 함량 및 항산화 활성의 경우 수확시기보다는 재배방법과 열처리에 의해 함량변화가 큰 것으로 나타났다. 하우스보다 노지 재배된 갯기름나물의 비타민 C, 엽산, 폴리페놀 화합물과 항산화활성이 증가하였으며 열처리할 경우 비타민 C, 베타카로틴, 폴리페놀 화합물, 항산화활성이 각각 증가하였다. 비타민 C의 기존 보고된 이론과 상이한 결과가 도출되어 다양한 열처리온도와 시간을 적용한 성분 변화 연구가 필요할 것으로 생각된다. 베타카로틴과 폴리페놀 화합물의 열처리에 의한 증가는 산화가수분해 효소의 불활성화와 세포조직의 견고성 저하로 인한 활성물질의 추출 효율증가로 설명될 수 있다. 따라서 나물을 데쳐서 섭취할 경우 미생물 오염방지 등 안전성을 확보할 수 있을 뿐만 아니라 나물 세포조직이 연해져 베타카로틴과 같은 우리 몸에 유익한 성분의 소화흡수율이 증가될 것으로 생각된다.

This study was carried out in order to investigate the early growth and root development characteristics of Peucedanum japonicum container seedlings. The experiment was performed by containers (128 and 200 cavities containers) and shading levels (0%, 35%, 50% and 75% shading). Germination rate of P. japonicum seeds was getting higher in the lower shading level and the highest in the full sunlight (71.9%). Plant height was the highest under 50% shading of all containers. Fresh weight and dry weight of the shoot (leaves + stem) were the highest under 50% shading of all containers, too. Meanwhile, fresh weight and dry weight of the root per plant were the highest under the full sunlight of 128 cavities container such as 0.34 g and 0.03 g, respectively. Total root length, root project area and root surface area were higher under the full sunlight of 128 cavities container such as 234.5 cm, 6.6cm2 and 20.8cm2, respectively and the next higher was under 35% shading such as 201.7 cm, 5.9cm2 and 18.4cm2, respectively. A case of root volume was the highest with 0.15cm3 under the full sunlight. As a result of the surveying the whole experiment, it is concluded that the shoot and root of P. japonicum seedling grow nicely by maintaining 35% shading.

This study was conducted to investigate the changes in the physicochemical properties of Peucedanum japonicum Thunb. after blanching. After blanching treatment, the crude protein content decreased but did not affect the crude fat, crude ash and carbohydrate contents of P. japonicum. All the detected free sugar contents decreased after blanching, but the total free sugar content decreased by 14.8% from that of the raw P. japonicum after blanching. The total amino acid and essential amino acid contents of the blanched P. japonicum. decreased by 10.75% and 15.22% from those of the raw P. japonicum. There were no differences in the contents of the total fatty acid between the raw and blanched P. japonicum. The total organic acid content decreased by 37.03% from that of the raw P. japonicum. after the blanching, and the reduction of the acetic acid was largest in the organic acid. The vitamin A, C and E contents decreased by 20.20%, 8.23% and 35.59% after the blanching. The total mineral content of the blanched P. japonicum. decreased by 21.84% after the blanching. The nutrients in the P. japonicum were essential amino acid, vitamin C, minerals, but these were reduced after the blanching. Therefore, the blanching conditions that can reduce nutrient loss of P. japonicum must be established.

1990~92년간 남부지방 식방풍 재배시 3요소 시용랑및 피복처리가 수량 및 품질에 미치는 영향을 조사코자 시험한 결과를 요악하면 다음과 같다. 1. 3요소 시용량 시험 가. 3요소 각각 결제에 의한 수량 감수율은 질소〉인산〉칼리순으로 적었다. 나. 식방풍뿌리중 회분 함량과 질소 시비랑과는 부의 유의 상관관계가 있었고, 칼리 시용량과는 정의 유의적인 상관관계가 있었다. 다. 남부지방에서 식방풍 일년생 수확시 시비적량은 N-P2O5-K2O=21-13-10kg/10a이었다. 2. 피복효과시험 가. 흑색비닐피복에서 출현율이 무피복 80%보다 6% 낮으나 수량이 7%정도 증수하므로 남부 지역에서는 흑색비닐피복재배가 좋을것으로 생각하며 투명비닐피복재배는 출현율이 낮아 수량이 25% 감수하였다. 나. 피복재료에 따른 식방풍의 품질조사결과 회분, 산불용성회분 및 엑기스 함량은 피복재료간 차이가 없었다.
