  • A leaf spot disease occurred on Allium tuberosum Roth. (Chinese chive) in Korea. All the isolates of Stemphylium sp. from the lesions of the diseased plant parts were identified as S. vesicarium (Waller.) Simmons, based on the morphological characteristics of conidia and conidiophores. Pathogenicity of the fungus was proved by artificial inoculation on Chinese chive plants. This is the first record of leaf blight on Chinese chive caused by S. vesicarium in Korea.

  • This study was carried out to find out major factors to mitigate carbon emission using Life Cycle Assessment (LCA). System boundary of LCA was confined from sowing to packaging during vegetable production. Input amount of agri-materials was calculated on 2007 Income reference of white radish, chinese cabbage and chive produced at open field and film house published by Rural Development Administration. Domestic data and Ecoinvent data were used for emission factors of each agri-material based on the 1996 IPCC guideline. Carbon footprint of white radish was 0.19 kg $CO_2kg^{-1}$ at open fields, 0.133 kg $CO_2kg^{-1}$ at film house, that of chinese cabbage was 0.22 kg $CO_2kg^{-1}$ at open fields, 0.19 kg $CO_2kg^{-1}$ at film house, and that of chive was 0.66 kg $CO_2kg^{-1}$ at open fields and 1.04 kg $CO_2kg^{-1}$ at film house. The high carbon footprint of chive was related to lower vegetable production and higher fuel usage as compared to white radish and Chinese cabbage. The mean proportion of carbon emission was 35.7% during the manufacturing byproduct fertilizer; white radish at open fields was 50.6%, white radish at film house 13.1%, Chinese cabbage at outdoor 38.4%, Chinese cabbage at film house 34.0%, chive at outdoor 50.6%, and chive at film house 36.0%. Carbon emission, on average, for the step of manufacturing and combustion accounted for 16.1% of the total emission; white radish at open fields was 4.3%, white radish at film house 15.6%, Chinese cabbage at open fields 6.9%, Chinese cabbage at film house 19.0%, chive at open fields 12.5%, and chive at film house 29.1%. On the while, mean proportion of carbon footprint for the step of $N_2O$ emission was 29.2%; white radish at open fields was 39.2%, white radish at film house 41.9%, Chinese cabbage at open fields 34.4%, Chinese cabbage at film house 23.1%, chive at open fields 28.8%, and chive at film house 17.1%. Fertilizer was the primary factor and fuel was the secondary factor for carbon emission among the vegetables of this study. It was suggested to use Heug-To-Ram web-service system, http://soil.rda.go.kr, for the scientific fertilization based on soil testing, and for increase of energy efficiency to produce low carbon vegetable.

  • Chinese chive (Allium tuberosum Rottler) has potential risks associated with pathogenic bacterial contamination as it is usually consumed raw. In this study, we investigated the microbiota of Chinese chives purchased from traditional markets and grocery stores in March (Spring) and June (Summer) 2017. Differences in bacterial diversity were observed, and the microbial composition varied across sampling times and sites. In June, potential pathogenic genera, such as Escherichia, Enterobacter, and Pantoea, accounted for a high proportion of the microbiota in samples purchased from the traditional market. A large number of pathogenic bacteria (Acinetobacter lwoffii, Bacillus cereus, Klebsiella pneumoniae, and Serratia marcescens) were detected in the June samples at a relatively high rate. In addition, the influence of the washing treatment on Chinese chive microbiota was analyzed. After storage at 26℃, the washing treatment accelerated the growth of enterohemorrhagic Escherichia coli (EHEC) because it caused dynamic shifts in Chinese chive indigenous microbiota. These results expand our knowledge of the microbiota in Chinese chives and provide data for the prediction and prevention of food-borne illnesses.

  • This study was conducted to observe the hematological effect of the small dogs when administrated excessive amount of the Korean native chinese chive(Allium tuberosum Rottler) extracts for a short period. In this experiment, clinically healthy dogs(n = 10, average weight = 4.17 kg) were used. They were inserted stomach tube and administrated the extracts(5ml/kg) for 7 days. The followings are the result of this experiment. The red blood cell counts, hemoglobin concentration and mean corpuscular hemoglobin concentration were significantly decreased. (P<0.05) The packed cell volume was slightly decreased. The mean corpuscular volume and methemoglobin concentration were significantly increased.(P<0.05) The white blood cell counts and reduced glutathione were slightly increased. Consequently, We determined that administrated excessive amount of the Korean native chinese chive extracts induced hemolytic anemia.

  • This study was carried out to elucidate the effect of mulching materials on the growth of Chinese chive (Allium tuberusum Rottler) and weed control. Chinese chive was grown under five mulching materials, pine leaf, oak leaf, rice straw, rice hull and sawdust, at the Experimental Farm of Chungbuk National University from June 20, 2009 to September 30, 2009. Amaranthus mangostunus, Digitaria sanguinalis, Portuclaca. oleracea, Echinochioa crus-galli var. frumetacea and Setaria viridis were dominant weeds. Both pine and oak leaves were significantly effective mulching materials in terms of weed control indices in both nursery and field. Soil moisture contents were 1.2~3.7% higher in mulching, especially in oak leaf mulching. Mulching with pine leaf significantly increased plant height, sheath length, leaf length, bulb-, root- and leaf-weights and yield of Chinese chive, but there were no significant differences among the other mulching materials although better than those in non-mulching.

  • 본 연구에서는 양수분 흡수율과 양이온 비율에 근거하여 백합과(부추)에 적합한 전용배양액을 개발하였다. 원예연구소 배양액액(NSH)을 1/2배액, 1배액, 3/2배액의 농도로 42일간 담액 수경재배를 한 결과 1/2배액에서 세가지 작물의 생육이 가장 좋았다. 양수분 흡수율에 근거하여 개발된 백합과 전용배양액(NSL)의 조성은 N 12, P 2.5, K 7, Ca 4 and Mg 2 me/L이다. NSL로 처리한 부추 작물의 상대생장율(RGR)은 1.11배 증가하였으며 엽록소 함량(SPAD value)은 1.16배 증가하였다. 그리고 부추의 가장 중요한 영양성분중 하나인 항산화성분-Ascorbic acid의 함량이 1.16배 증가하였다.

  • In this study, we characterized sporadically occurring sclerotium rot caused by Sclerotium rolfsii in Chinese chive (Allium tuberosum Roth.) in farm fields in Sacheon, Korea. The initial symptom of the disease was water-soaked, which progressed to rotting, wilting, blighting, and eventually death. Further, mycelial mats spread over the lesions near the soil line, and sclerotia formed on the scaly stem and leaves. The sclerotia were globoid, 1~3 mm, and white to brown. The optimum temperature for growth and sclerotia formation on potato dextrose agar (PDA) was $30^{\circ}C$. The diameter of the hypae ranged from 4 to 8 ${\mu}m$. Clamp connection was observed on PDA medium after 5 days of incubation. Based on the mycological characteristics, internal transcribed spacer sequence analysis, and pathogenicity test, the causal agent was identified as Sclerotium rolfsii Saccardo. This is the first report of sclerotium rot in Chinese chive caused by S. rolfsii in Korea.

쌀겨, 보릿겨 처리가 부추와 토란의 생육과 수량 및 잡초방제에 미치는 영향 (Effect of Rice Bran and Barley Bran Application on Growth and Yield of Chinese Chive (Allium tuberosum Rottler) and Taro (Colocasia esculenta) and Weed Control)

  • 본 연구는 쌀겨, 보릿겨, 태운 쌀겨 및 태운보릿겨를 부추와 토란을 파종하기 전에 시용하고 이들 작물의 생육과 수량증대에 미치는 영향을 알아보기 위해 수행하였다. 이들 4가지 겨류를 처리하고 처리 후 13, 27, 41, 57일 째 조사한 결과 부추의 초장은 보릿겨수비 처리구에서는 조사 전 기간에서 무처리구보다 유의적으로 컸던 반면 다른 처리구에서는 큰 차이를 볼 수 없었다. 또한 겨류처리에 의한 부추 개체수에서도 무처리와 큰 차이가 없었다. 그러나 처리 후 57일 째 조사한 생체중은 무처리구에 비해 4가지 겨류처리구에서 약 2배 많았다. 이들 차이가 토양 화학성분과 관련성이 있는지 알아보기 위해 처리 후 57일째에 토양의 화학성분을 분석한 결과 겨류를 처리한 토양에는 유기물과 유효인산 등이 풍부하였다. 부추 예취 후 14일에 재생한 부추의 지상부 생체중은 4가지 겨류 처리구에서 무처리구에 비해 높은 경향이었으나 보릿겨 처리구에서만 무처리구에 비해 유의적으로 높았다. 4가지 겨류 처리 후 10cm 토란을 이식한 경우, 보릿겨처리구에서만 토란의 지상부 및 지하부 생장량이 무처리에 비해 증가하였다. 그러나 겨류처리 후 종자를 파종 한 경우 오히려 겨류처리에 의해 토란 수량이 감소한 것으로 보아 겨류효과는 작물의 종류 및 이식시기에 따라 다름을 알 수 있었다. Pot 조건하에서 쌀겨 및 보릿겨 처리(2,000, $4,000kg\;ha^{-1}$) 후 15일에 조사한 피, 바랭이, 명아주 및 까마중에 대한 잡초방제 효과는 아주 적었고, 포장조건하에서도 겨류처리에 의한 잡초방제 효과는 아주 적었다. 그러나 쌀겨를 ha당 4,000kg 처리 수준에서는 배추와 쑥갓에서 각각 62.6%와 37.2% 생육 저해가 나타났고 그 밖의 옥수수, 호박, 오이 및 부추의 경우에서는 0~19.6%의 생육저해 현상이 나타났다. 보릿겨의 경우도 배추를 제외한 작물종에서 쌀겨와 유사한 생육저해를 보였다.
