  • This study was conducted to determine feasibility of production system of Perilla frutescens leaf-stem by fertilizing of Sta-Green in pots. Germination rate of Perilla frutescens seeds collected in 2002 was $7\%$, also germination rate of seeds collected in 2003 was $62\%$, while germination rate of seeds collected in 2004 was above $93\%$. Seed germination rate of Perilla frutescens collected in 2004 were higher than seed gathering in 2002. Especially, plant growth and yield of Perilla frutescens grown in pot(The pots was filled with soil mixtures of Sta-Green and Peat Moss mixed with 40:60 ratio.) was the highest. These results indicate that leaf and stem production of Perilla frutescens can be improved by fertilizing of Sta-Green in pots.

  • The objectives of this study were to develop a harvesting gripper for perilla leaves and test its performance, which was a partial work of the automated perilla leaves harvesting system development. The results of this study could be summarized as the followings: The shear forces for harvesting the perilla were measured. The measured results showed that the average shear force required was 12.13N for cutting the petioles attached to the perilla stalks, and the maximum of 17.42N. The inner diameter of air cylinder used was 6mm and the air pressure was maintained as 0.7㎫ during the tests. The time required for cutting perilla leaves could be adjusted by the control program and cutting operation could be done within 1- 10 seconds. The performance tests were conducted to harvest the perilla leaves by the gripper developed. The average success rates of cutting were 72.2% for the first test, 78.5% for the second, and 74.2% for the last. The perilla leaves were not damaged by the gripper The whole system operation could be finished within three seconds except the delay time for dropping harvested leaves.

  • 들깨잎말이명나방(Pyrausta panopealis)은 잎들깨의 주요해충이다. 피해양상은 유충이 들깨신초 부위에서 거미줄을 치고 가해하는 양상을 보이며 심할 경우 대를 끊어 놓아 더 이상 수확을 할 수 없게 만든다. 이러한 들깨잎말이명나방의 경제적 피해수준과 요방제 수준 평가를 시설하우스에서 수행하였다. 다른 해충들의 피해를 피하기 위하여 망사케이지를 이용하여 시험구를 격리시켰다. 들깨잎말이명나방 유충의 접종밀도는 발생초기 100개의 잎들깨를 처리구로하여 100주당 $1{\sim}20$주에 주당 2마리씩 6월 13일에 접종하였다. 6월 23일까지 피해주율, 피해엽수은 증가하였으나 반면에, 6월 23일 이후에는 증가하였다. 수확량 또한 동일한 결과를 보였다. 시장가격에 대한 나방 방제비용의 비율로 계산된 경제적 손실 시점은 4.0%였다. 이때의 경제적 피해수준은 100주당 유충 5.1마리였으며, 경제적 피해수준은 80% 수준에서 설정된 요방제 수준은 100주당 유충 4.1마리였다.

  • 본 연구에서는 들깨 시설재배지 토양 및 작물 중 잔류성유기염소계 농약의 잔류량을 조사하였다. 토양 및 작물 중 잔류성유기염소계 농약 분석을 위한 추출 및 정제는 QuEChERS 방법을 다소 개선한 방법으로 수행되었다. 들깨 시설재배지 토양 및 농산물 중 잔류성유기염소계 농약의 회수율은 각각 76.3-113.4 및 79.4-107.3%, 정량한계는 각각 0.03-0.24와 $0.33-0.50{\mu}g/kg$ 수준이었다. 들깨 시설재배지 토양에서 dieldirn 및 endosulfan sulfate 2 성분만이 각각 1.6-9.2 및 $22.0-87.8{\mu}g/kg$ 수준으로 검출되었으나 들깻잎의 모든 시료에서는 검출되지 않았다. 이러한 결과는 들깨 시설재배지 토양이 농산물 안전성을 위협할 정도로 잔류성유기염소계 농약으로 오염되지 않았음을 나타냈다.

  • 2004년 잎들깨 주요 해충을 조사하였던 바, 잎들깨 시설하우스내에서 발생하는 주요 해충들은 들깨진딧물(Aphis egomae), 들깨잎말이명나방(Pyrausta panopealis), 점박이응애(Tetranychus urticae), 차먼지응애(Polyphagotarsonemus latus), 차응애(Tetranychus kanzawai) 등이었다. 그 중에서 들깨진딧물은 방제를 하지 않았을 경우 100%에 가까운 피해를 주는 중요한 해충으로 밝혀졌다. 본 연구는 발생초기 100주당 1마리에서 80마리 수준으로 들깨진딧물 성충을 인위적으로 접종하였을 경우 잎들깨 포장에서의 경제적 피해 수준과 요방제수준을 밝히고자 수행 하였다. 100주당 $1{\sim}80$마리가 접종되었을 때 평균 피해주율은 6월 하순경 $2.4%{\sim}40.5%$였다. 시험기간 동안의 방제비용(C)를 시장가격(V)으로 나누었을 때 진딧물의 발생초기인 4월부터 6월 13일까지 경제적 손실을 일으키는 시점은 5.8%였으며 진딧물의 발생최성기인 6월 13일부터 6월 30일까지의 경우 9.3%였다. 들깨진딧물의 발생 초기에서의 경제적 피해수준은 주당 5.3마리였으며 발생최성기 때의 경제적 피해수준은 주당 0.6마리와 7.6% 피해주율 이었다. 경제적 피해수준의 80% 수준에서의 요방제 수준은 들깨진딧물의 발생최성기인 6월의 경우 주당 0.5마리와 피해주율 6.1%였다.

  • Beta-carotene and lutein contents in 7 different green leafy vegetables(perilla leaf, mugwort, chwi, lettuce, spinach, leek, and crown daisy) were analyzed by HPLC. The isocratic separation was performed on a ${\mu}-Bondapak$ $C_{18}$ column with a solvent system of acetonitrile : dichloromethane : methanol = 70:20:10. To check the reliability of the method applied, precision and recovery tests were performed. Perilla leaf showed the highest ${\beta}-carotene$ content(12,570 ${\mu}g$ / 100 g), followed by mugwort and chwi, all of those have ${\le}10,000\{\mu}g\{\beta}-carotene$ per 100 g vegetables. Green lettuce, spinach, leek, crown daisy and reddish brown lettuce contained 9,869, 6,689, 5,664, 3,601 and 3,299 ${\mu}g\{\beta}-carotene/100 g$, respectively, Lutein content was the highest in perilla leaf($13,718{\mu}g/100 g$) followed by chwi($11,989{\mu}g/100 g$), mugwort($11,522{\mu}g/100 g$), green lettuce($10,307{\mu}g/100 g$) and spinach($10,115{\mu}g/100 g$). ${\beta}-carotene$ contents in perilla leaf, mugwort, chwi and green lettuce were 47.8~49.6% of total carotenoids, and ${\beta}-carotene$ contents in the other green leafy vegetables analyzed were 37.7~41.4% Vitamin A contents of green leafy vegetables analyzed by HPLC were 2~6 times higher than the vitamin A values shown in food composition tables except crown daisy.

  • 충남 금산지역 잎들깨 시설하우스에서 차먼지응애(Polyphagotarsonemus latus)는 5월 하순 최초 발생하기 시작하여 6월 중순에 1차 최대 발생양상을 보인 후 7월 상순부터 급격히 밀도가 증가하여 7월 중순 가장 밀도가 높은 2차 최대 발생양상을 보였다. 방제방법에 따라 발생양상에는 차이가 없었으나 밀도에는 차이를 보여 화학약제를 사용하는 하우스에서 가장 높았고 유기농업자재를 사용하는 하우스에서 가장 낮았다. 이는 크기가 작아 육안으로 관찰할 수 없는 차먼지응애를 방제하기 위해 화학약제를 사용할 경우, 농약 잔류 문제로 지속적인 사용을 못하므로 밀도가 높아지고, 유기농업자재를 사용하는 경우에서는 농약잔류에 대한 걱정 없이 유기농업자재를 지속적으로 사용함으로써 방제가 이루어졌던 것으로 판단된다. 잎들깨 주간내 발생양상을 조사한 결과, 차먼지응애는 접종 25일 후 최대 발생밀도를 보였고, 중엽, 성엽, 신초의 순으로 알과 약성충의 총밀도가 조사되었다. 그러나 엽장과 차먼지응애 밀도와의 상관성 분석 결과, 상관성이 없어 차먼지응애 발생예찰시 어떤 샘플을 채취해도 정확한 예찰이 이루어질 것으로 판단된다.

  • Flavonoids in commerical green-yellow vegetables (carrot, mugwort, perilla leaf, leek and water dropwort) were analyzed by HPLC. Flavonoids analyzed in samples were myricetin, luteolin , qercetin, apigenin and kaempferol. When 2N HCI and a reaction period of 1 hours was used, quercetin and kaempferol could be detected in leek and water dropwort, luteolin and apigenin could be detected in perilla leaf. Increasing reaction period up to 6 hours with 2N HCI led a degradation of quercetin and kaempferol to approximately 90% in leek and water dropwort, but it led to a increasing of luteolin and apigenin of maximum 300% in perilla leaf. After the blanching process, the amount of the flavonoids increased whereas the components of the flavonoids were not changed.

  • The testing materials which kept perilla frutescens' leaves frezen are divided into four parts, 1. freezing green leaves, 2. glucose added to the leaves dried in the sun, 3. glucose unadded to the leaves dried in the sun and 4. the leaves dried in the immediately after collecting sample. The perilla frutescens' leaves are treated with the artificial digestion test to investigate the effects of the digestibility of ingredients and of protein. The results obtained were as follows ; 1. The digestibility of crude protein of sample using the common leaves dried in the sun immediately after collecting sample was presented highest at 83.15%, the freezing green leaves at 68.35%, glucose added to the leaves dried in the sun at 64.25% and glucose unadded to the leaves dried in the sun at 62.12%. The digestibility of perilla frutescens' by freezing green leaves, glucose added or glucose unadded to the leaves dried in the sun is on the decrease without difference. 2. It was suggested that glucose and reductive sugars to perilla frutescens' leaves is not affected by the decreased digestibility of protein, dince the digestibility of glucose added to the leaves dried in the sun and glucose unadded to the leaves dried in the sun almost never makes a difference. 3. The digestibility of freezing the green leaves for six months was quite different from the leaves that were dried in the sun immediately after collecting sample, in that the leaves that were frozen for six months were decreased 1/5 quantity of the shole crude protein.

  • The objective of this study were to assess rooftop urban agriculture and analyze the differences in soil, growth, physiology, and productivity to elucidate the effect of companion planting with various plants, including lettuce (Lactuca sativa), rosemary (Salvia rosmarinus), marigold (Tagetes patula), Korean perilla (Perilla frutescens), and garlic chives (Allium senescens). Measurements were taken every other week from May to August 2023, totaling eight measurement. Regarding the characteristics of the soil planted with lettuce and aromatic plants, the combined planting of lettuce and garlic chives created a favorable soil environment for plant growth. Consequently, the best growth was observed when lettuce and garlic chives were companion planted. Companion planting of lettuce and garlic chives appears to be the most efficient concerning growth and physiology. The productivity of companion planting lettuce and aromatic plants also showed high-quality lettuce when lettuces and garlic chives were companion planted. Therefore, companion planting of lettuces and garlic chives in rooftop urban agriculture is suitable for growth, physiology, and productivity.
