Abstract
Four species of nematodes attacking mushroom beds were found in samples taken from 35 mushroom farms throughout Korea. These were Rhabditis sp., Aphelenchoides sp., Ditylenchus sp. and Aphelenchus sp. ,Rhabditis sp. was found from compost and casing from all mushroom farms and the frequencies of Aphelenchoides sp. was 31.4% in the both compost and casing. Both Ditylenchus sp. and Aphelenchus sp. showed 2.7% of frequencies in the compost, none in casing. Temperature and moisture content of compost affected pathogenicity of Aphelenchoides sp. on mushroom mycelia grown in compost. The higher temperature and moisture content the sooner the damage became apparent, and the more rapid was subsequent destruction of mycelia. There was no mycelial destruction at the lowest temperature of
본시험은 우리나라 양송이 재배균상에서 서식하는 선충(線蟲)의 종별(種別) 발생빈도(發生頻度)와 Aphelenchoides sp.의 환경적 요인의 영향에 따른 양송이균사 가해정도 및 Rhabditis sp.의 양송이균사 가해여부를 구명코자 실시하였다. 시험결과 전국 35개 재배농가에서 수집된 퇴비와 복토에서 Rhabditis sp. Aphelenchoides sp. Ditylenchus sp. Aphelenchus sp.등 4개의 종(種)에 속하는 선충이 발견되었으며 Rhabditis sp.는 모든 농가의 퇴비와 복토에서 발견되었고 Aphelenchoides sp.는 퇴비와 복토에서 각각 31.4%, Ditylenchus sp.와 Aphelenchus sp.는 퇴비에서 각각 2.7%의 빈도를 보였고 복토에서는 발견되지 않았다. Aphelenchoides sp.는 온도 및 퇴비수분함량에 따라 양송이 균사가해정도에 차이가 있었으며 온도 혹은 퇴비수분함량이 높을수록 균사피해가 조기에 나타났으며 균사소멸기간도 단축되었다.
