Abstract

Although there were differences depending on strains and environmental conditions, virus infected oyster mushroom, Pleurotus florida showed slow growth on sawdust and rice straw substrates. Many harmful microorganisms occurred on the cultural bed of virus infected isolates. Pinhead formed too densely or too rarely sometimes. Stipes of the mushrooms were long slightly bent with small cap. The virus infected mushrooms formed branch on their stipes. The first pinheading days of the infeeted mushroom were later than that of healthy culture. The loss of fruit body yield was about 30% compared with that of virus free culture. Spores which contaminated by viruses damaged more seriously than the other source. The authors would like to call these symptoms as a new disease in oyster mushroom culture in the world.

Virus에 감염(感染)된 느타리버섯은 계통(系統)이나 재배환경(栽培環境)에 따라서 차이(差異)가 있으나 대체로 균사생장(菌絲生長)이 부진(不振)하며 버섯 원기형성(原基形成)이 과밀(過密)하거나 불량(不良)하였다 . 균상(菌床)은 잡균(雜菌) 발생이 많았으며 대는 길고 굽으며 가지를 형성(形成)하였다. 갓은 대에 비(比)하여 작으며 평형(平形)이고 갓색(色)은 다소 짙은 경향이였다 . 초발아(初發牙)가 늦고 자실체(子實體) 수량(收量)은 건전균주(健全園珠)에 비하여 약 30% 정도(程度) 감수(減收)하였으며 이병(罹病)된 포자(胞子)로 접종(接種)하였을 때 감수율(減收率)이 높았다 .
