초록

본 연구에서는 흑타리버섯을 물, 에틸아세테이트, 클로로포름, 부탄올 등으로 추출하였다. 각 유기용매를 이용한 흑타리버섯 추출물의 항균 활성을 1차적으로 평판 확산방법을 사용하여 항균력을 검증하였다. 부탄올 추출물에서 가장 높은 항균력을 확인하였고, 1%, 2.5%, 5%, 7.5%, 10% 농도로 항균력을 확인하였을 때도 부탄올 추출물이 가장 높은 항균활성을 확인하였다. 위의 결과를 통해 실제 포장실험에서도 가능성을 확인하여 온실에서 F. fujikuroi Nirenberg의 억제력을 확인해본 결과 흑타리버섯 부탄올 추출물을 7.5% 첨가하였을 때 .80%의 높은 억제력을 확인할 수 있었다. 또한 초기의 발아력과 파종 후 30일 경과 후에 확인한 초기 생육특성에서도 흑타리버섯 추출물의 5% 이상에서는 방제에 효과가 높았으며 7.5% 이상 시에는 초장 및 묘소질이 대조구와 비교하여 통계적 유의차가 없는 높은 방제효과를 확인할 수 있었고 이러한 결과로 볼 때 흑타리버섯 추출물은 벼 키다리병에 대하여 높은 방제효과가 있으며 향후에는 친환경 종자소독제로써 활용가능성이 높을 것으로 판단된다.

This study was carried out to investigate antimicrobial activities of water extracted Pleurotus ostreatus var Heuktari (PO), and their application to F. fujikuroi Nirenberg growth inhibition material. Various organic solvents (chloroform, hexane, ethyl acetate, ethanol) were tested to investigate the antimicrobial activities of Pleurotus ostreatus var Heuktari against F. fujikuroi Nirenberg. Chloroform, hexane, ethyl acetate and hot water extracts had no antimicrobial activities, but butanol extract showed 2.5% strong activities in order of F. fujikuroi Nirenberg disk diffusion test. Then we observe Antifungal activity using green house. Bed soil and mushroom extract mixed at 10%, 7.5%, 5%, 2.5%, 1% total bed soil mass. Screening of Antifungal activity was tested two periode 18day and 25day. The Antifungal activity rate of each period and extract density was 7.5% mixed bedsoil has investigated 80% Antifungal activity rate. The result indicates that the Pleurotus ostreatus var Heuktari extract using F. fujikuroi Nirenberg registance, which shows the development of organic agriculture seed disinfectant.
