Occurrence of Tropical Race 4 of Fusarium oxysporum f. sp. cubense in Indonesia
한국식물병리학회 The Plant Pathology Journal 5 Pages
한국식물병리학회 The Plant Pathology Journal 2011, 27권 3호 10 280-284 (5 pages)
Fusarium wilt of banana caused by Fusarium oxysporum f. sp. cubense is widespread in Indonesia. However, the distribution of tropical race 4 strains has not been well studied. Thirty nine isolates of F. oxysporum f. sp. cubense were collected from Java and 7 isolates were from Sumatera, Bangka, and Kalimantan. All isolates produced volatile odor when grown on steamed rice. These isolates were further tested for their vegetative compatibility with nitM testers of 20 reported vegetative... -
Control Efficacy of Phloretin Isolated from Apple Fruits Against Several Plant Diseases
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 3호 13 280-285 (6 pages)
In the course of a searching natural antifungal compounds from plant sources, we found that the methanol extract (3,000 μg/ml) of Malus domestica fruits had potential of control against rice blast (Magnaporthe grisea) and tomato late blight (Phytophthora infestans). Under bioassay-guided purification, we isolated phloretin, a phenolic compound, with in vivo antifungal activity against M. grisea. By 1-day protective application of phloretin (500 μg/ml), the compound strongly inhibited the... -
Characteristics of Cucumber mosaic virus Infecting Zucchini in Korea
한국식물병리학회 The Plant Pathology Journal 10 Pages
한국식물병리학회 The Plant Pathology Journal 2010, 26권 2호 6 139-148 (10 pages)
A virus causing stunt, yellowing, severe mosaic, malformation symptoms on leaves and uneven development and malformation on fruits of zucchini was prevalent around Goseong, Gyeongsangnam-do, Korea. A survey conducted (2004) in the Goseong area revealed about 20% virus infection rate. The disease causative identified as Cucumber mosaic virus (CMV-Z1) was further characterized. The isolate induces mosaic symptoms on Cucumis sativus, while severe mosaic, stunt and malformation on C. pepo. Thin... -

온난화가 진행되면, 우리나라에서 재배되고 있는 주요 벼의 생육과 생산량이 어떻게 변화되는지를 알아보기 위해, 북 부지방과 중부지방에 각각 가장 많이 재배되는 오대벼와 새추청벼의 유식물을 각각 대조구, 온도 상승구 및 CO2+온도 상 승구에서 재배하여 그 결과를 비교하였다. 새추청벼의 지상부생물량, 지하부생물량, 총 생물량, 개체당 이삭무게 그리고 낟알의 숙성 비율은 온도 상승구에서, 오대벼는 CO2+온도 상승구에서 가장 높았다. 새추청벼와 오대벼의 개체당 이삭수 는 환경구배 간 차이가 없었다. 새추청벼의 이삭당...
