In this study, we investigated the changes of growth characteristics, mineral and chlorophyll content of young leafy vegetable of Chinese toon grown under greenhouse and open fields. Results showed that growth of young leafy vegetable of Chinese toon was somewhat accelerated in greenhouse compared to the open field. In case of apical bud growth, several parameters such as plant height, number of branch, fresh weight and chlorophyll content showed similar tendency in both greenhouse and open field. In the changes of minerals, N content in apical buds recorded significant increase to 3.1 times compared to that of later buds. Its content was 1.2 times higher in greenhouse than that of open field. Mineral contents including P, Ca, Mg and Fe were significantly increased in greenhouse. Highest ascorbic acid content was observed in lateral buds grown in greenhouse and then it was followed such as lateral bud in open field, apical bud in open field, and apical bud in greenhouse, in turn. These results indicate that greenhouse culture could be applicable to new culture in order to produce young leafy vegetable of Chinese toon with high quality.

일반적으로 식물의 공급방법은 채집과 재배로 나눌 수 있으며, 자원식물은 상용화를 위해는 안정적 공급이 선행되어야 하므로 재배를 선호하고 있다. 재배방식은 다시 노지재배, 시설재배, Indoor Farm(식물공장)으로 나눌 수 있으며, 우리나라는 시설재배 중 비닐하우스 활용이 활발한 나라로 평가된다. 노지재배에 비해서는 시설재배가 온/습도 관리에 대해 장점을 가지고 있으며, Indoor Farm(식물공장)은 광량, 광질 및 일조시간까지 전체 생육조건의 조절이 가능하지만 초기투자비용 및 운영비용 등으로 인해 경제성이 낮아 아직까지는 상용되고 있지 않다. 자원식물의 경우 부가가치가 높아지는 후방사업으로 발달할 수 있으나, 화장품, 기능식품 또는 의약품으로 개발하기 위해서는 일정한 품질을 확보하여야 한다. 자원식물 재배 시 특정 성분의 함량을 일정하게 유지하기 위해서는 온/습도, 광량, 광질 등 생육환경을 관리할 수 있는 시설재배가 노지재배에 비해 적합하다. 하지만, 일부 자원식물의 경우에는 위도, 일조량 등으로 인해 국내에서는 시설재배로도 적절한 생육조건을 제공할 수 없어서 상업화하지 못한 경우가 많았다. 이에, (주)넥스트온은 Indoor Farm(식물공장) 전문기업으로서, 기존 자원식물 중 국내에서 시설재배로는 적절한 품질 확보가 불가했던 자원식물 및 특수 생육환경에서만 자생하는 희귀 자원식물의 양산화에 노력하고 있다.

Perilla leaves cultivated in greenhouses (Jan., May) and in the fields (Aug.) of Geumsan province were investigated for their extract yields and physiological functionalities. The yield was highest in 30% ethanol extracts of the August perilla leaves. The highest fibrinolytic activity (8.2 U) was observed in 30% ethanol extracts of the May perilla leaves, while the HMG-CoA reductase inhibition level, which is related to the inhibition of cholesterol biosynthesis, was 83% in water extracts of the August perilla leaves. Anti-hypertensive ACE inhibitory activity was 64.5% in the water extracts of the January perilla leaves, and antioxidative electron donating ability was the highest (69%) in 30% ethanol extracts of the August perilla leaves. Elastase inhibitory activity, which is related to the inhibition of skin aging, was highest (47.5%) in 30% ethanol extracts of the May perilla leaves. However, SOD-like activity, nitrite scavenging activity, and tyrosinase inhibitory activity were not detected were very weak in all samples.

This study investigates the cultivation processes of major nuts and fruits such as Ginkgo biloba L., Vitis coignetiae, Actinidia arguta Planch, Rubus coreanus Miq., and Rubus crataegifolius and analyzes standard income in order to provide foundational data necessary to make reasonable policies related with the criteria of compensating the loss of forest products or diagnosis of forestry management. According to the research results, the types of cultivation by items can be largely divided into open field culture and mountainous culture. Regarding the average annual income per unit area (3.3) by items, the open field culture of Ginkgo biloba L. was 1,060 Won, mountainous culture of Ginkgo biloba L. was 618 Won, open field culture of Vitis coignetiae was 5,891 Won, mountainous culture of Actinidia arguta Planch was 8,113 Won, open field culture of Rubus coreanus Miq. was 14,701 Won, and open field culture of Rubus crataegifolius was 17,482 Won or so; thus, the average annual income of Rubus coreanus Miq. and Rubus crataegifolius was very higher than that of the other items. In particular, because the production of Rubus crataegifolius starts two years after the planting and they rely on family labor mainly for the cultivation, the expenses for employment and labor were analyzed to be low. In addition, the analysis shows that at most of the nuts and fruits cultivation, initial investment costs for facilities or seedlings occupy a great part as about 30% averagely out of the management cost, so it is thought that the government should provide proper support to vitalize the cultivation.

This study was conducted with the intention of providing basic data that are essential for establishing compensation standards for forest products and diagnosing forestry management in the future by investigating the cultivation process of major wild edible greens such as Pteridium aquilinum var. latiusculum, Ligularia fischeri, and Allium victorialis and analyzing related incomes. According to the result, the cultivation was generally divided into the open filed cultivation and mountain cultivation by the cultivated item. The annual average income by unit area ($3.3m^2$) for each item was 6,500 won for Pteridium aquilinum var. latiusculum cultivated open filed, 3,200 won for Pteridium aquilinum var. latiusculum cultivated in the mountain, 20,400 won for Ligularia fischeri cultivated open filed, 20,900 won for Allium victorialis cultivated open filed, and 7,300 won for Allium victorialis cultivated in the mountain. Particularly, while consumer demand for Allium victorialis and Ligularia fischeri are increasing phenomenally recently, the annual average income per unit area ($3.3m^2$) for these wild edible greens grown open filed was distinctively higher than that for Pteridium aquilinum var. latiusculum. This can be explained by very high working expenses (land rent and labor cost) required for the cultivation of Pteridium aquilinum var. latiusculum compared with other items. As for Ligularia fischeri and Allium victorialis yielding high annual average income, the initial investment costs including the cost of purchasing seeds and seed stocks account for 40% of the working expenses or over and thereby requiring proper support from the government for solidifying the income source and promoting cultivation in the agricultural and mountain regions in the future.

LCA (Life Cycle Assessment) carried out to estimate carbon footprint and to establish of LCI (Life Cycle Inventory) database of pepper production system. Pepper production system was categorized the field cropping (redpepper) and the greenhouse cropping (greenpepper) according to pepper cropping type. The results of collecting data for establishing LCI D/B showed that input of fertilizer for redpepper production was more than that for greenpepper production system. The value of fertilizer input was 2.55E+00 kg $kg^{-1}$ redpepper and 7.74E-01 kg $kg^{-1}$ greenpepper. Amount of pesticide input were 5.38E-03 kg $kg^{-1}$ redpepper and 2.98E-04 kg $kg^{-1}$ greenpepper. The value of field direct emission ($CO_2$, $CH_4$, $N_2O$) were 5.84E-01 kg $kg^{-1}$ redpepper and 2.81E+00 greenpepper, respectively. The result of LCI analysis focussed on the greenhouse gas (GHG), it was observed that the values of carbon footprint were 4.13E+00 kg $CO_2$-eq. $kg^{-1}$ for redpepper and 4.70E+00 kg $CO_2$-eq. $kg^{-1}$ for greenpepper; especially for 90% and 6% of $CO_2$ emission from fertilizer and pepper production, respectively. $N_2O$ was emitted from the process of N fertilizer production (76%) and pepper production (23%). The emission value of $CO_2$ from greenhouse production was more higher than it of field production system. The result of LCIA (Life Cycle Impact Assessment) was showed that characterization of values of GWP (Global Warming Potential) were 4.13E+00 kg $CO_2$-eq. $kg^{-1}$ for field production system and 4.70E+00 kg $CO_2$-eq. $kg^{-1}$ for greenhouse production system. It was observed that the process of fertilizer production might be contributed to approximately 52% for redpepper production system and 48% for greenpepper production system of GWP.

마카(Maca, Lepidium meyenii Walp)는 십자화과 두해살이풀로서 페루의 안데스 산맥이 원산지이며 세계 여러 나라에서 건강기능식품, 음료 등의 가공원료로 이용되고 있다. 최근 마카의 기능성 성분이 밝혀지면서 국내에서도 재배 면적이 증가하고 있으나 연작장해, 동계 저온으로 인한 고사 등으로 인하여 생산량은 매우 저조한 실정이다. 따라서 본 연구에서는 노지 환경에서 비닐피복과 지상부에 비닐 터널을 처리하여 겨울철 고사율을 줄이고 연장장해를 회피하여 마카를 안정적으로 재배하고자 실시하였다. 마카 재배는 경상북도 경산지역에서 2017년 9월 24일 파종하여 2018년 4월 30일에 수확하였으며, 처리는 비닐피복, 비닐피복+터널, 비가림하우스 및 대조구로 노지에서 무피복재배로 실시하였다. 동해에 의한 마카 고사율은 비닐피복과 노지재배에서 55.7, 79.1%였으나 비닐피복+터널과 비가림하우스에서는 3%이하로 조사되어 노지환경에서 비닐피복 후 지상부 터널설치로 동해를 방지할 수 있었다. 수확 시 마카의 생체중은 비가림하우스에서 주당 57.8g으로 가장 높았으며, 비닐피복+터널설치, 비닐피복 및 노지재배에서 각각 52.7, 21.3, 10g으로 조사되어 동계 지상부 15cm 지점의 평균온도(비가림하우스 : $3.4^{\circ}C$, 비닐피복+터널설치 : $1.9^{\circ}C$, 노지 : $-2.1^{\circ}C$)와 정의 상관관계를 나타냈다. 마카의 이용부위인 뿌리의 무게는 비가림하우스와 비닐피복+터널에서 각각 주당 15.5, 19.9g으로 조사되어 비교적 비닐피복+터널처리의 생육이 좋았으나 통계적 유의성은 없었다. 마카는 다닥냉이속 작물로 저온경과 후 뿌리비대가 이루어지는 속성을 가지고 있으나 생육후기 고온으로 인한 지상부 생육은 뿌리비대를 저하시키는 것으로 추정되어 3월 이후 온도관리는 좀 더 연구가 진행되어야 할 것이다. 노지와 비닐피복 재배에서는 뿌리의 무게가 주당 3.9, 2.7g으로 정상적인 수확이 불가능하였다. 마카를 노지에서 재배할 경우 비닐피복 후 지상부에 터널을 설치하면 연작장해 회피와 동해에 의한 고사율을 줄일 수 있어 안정적인 재배가 가능한 것으로 판단되었다.
