Gaeumannomyces graminis var. tritici 에 의한 벼 엽초 썩음병
성재모,박종성,이승찬 한국균학회 1982 韓國菌學會誌 Vol.10 No.4
Gaeumannomyces graminis var. tritici was first isolated from rice in 1981. Sheath rot of rice seedling in box culture for machine transplanting was produced by artificial inoculation of the causal organism. Especially sheath rot was developed from crown to leaf sheath above water level. Perithecia were usually formed in dead leaf sheaths and in PDA culture. They were black, globose, and immersed with obliquely crumpent neck. Asci were unitunicate with an apical ring and contained 8 spores. Ascospores were hyline, slender, 80∼104 um in length. Each spore showed 3∼4 septa. Based on morphological and cultura characteristics, the isolate from seeds was identified as Gaeumannomyces graminis (Sacc.) Arx & Olivier tritici J. Walker.

In order to investigate flight number of ascospores of the wheat scab fungus as a primary inoculum, the experiment was undertaken at three localities including Suweon during the two years 1979 to 1980. Ascospore flight of the fungus was begun at the first part of April, and amounts of flight number of ascospores were varied by different localities. It showed a tendency that Large number of ascospore fllight was proportionally resulted by higher amounts of rainfall. As a result, a high positive correlation was obtained between flight number of ascospores of the fungus and amounts of rainfall.
