벼種子 傳染性 病原菌의 發生에 미치는 培養 方法 및 光源의 影響 = Effects of Incubation Methods and Light on the Growth of Seed-Borne Pathogenic Fungi in Seed Health Testing of Rice

국문 초록 (Abstract)

벼品種 豊玉에 寄生하는 중요한 種子傳染性 病原菌의 發生에 미치는 培養方法 및 光源의 영향을 調査한 結果를 보면 다음과 같다.
1) Blotter method에서는 8種의 種子傳染性 病原菌이 檢出되었으나 Agar plate method에서는 4種의 種子傳染性 病原菌만 檢出되었다.
2) 계속 暗黑處理에서는 5種의 種子傳染性 病原菌이 檢出되었으나 近紫外線과 暗黑 12時間 交互照射 및 晝光色光線과 暗黑 12時間 交互照射處理에서는 각각 8種의 種子傳染性 病原菌이 檢出되었다.
3) 도열병균(Pyricularia oryzae)은 Agar plate method 와 暗黑處理에서는 檢出되지 않았으며 近紫外線과 暗黑 12時間 交互照射處理가 晝光色光線과 暗黑 12時間 交互照射處理에 비하여 效果가 있었다.
4) 이삭마름병균(Trichoconis padwickii)도 暗黑에서는 檢出되지 않았으며 近紫外線과 暗黑 12時間 交互照射處理가 晝光色 光線과 暗黑 12時間 交互照射處理에 비하여 현저히 效果가 있었다.

The effect of incubation method and light on the development of an important seed-borne fungi which are parasiting on Pung-ok, a variety of rice, was investigated. Two incubation methods, Blotter method and Agar plate method were used. Three light conditions, cycles of 12 hour light/12 hour darkness with near ultraviolet light, the same cycles with artificial daylight, and continuous darkness were given. The results were as follows:
1. Eight different species of seed-borne fungi were detected when incubated by Blotter method, while only four species were detected by Agar plate method.
2. Either when incubated under the cycles of 12 hour light/12 hour darkness with near ultraviolet or artificial daylight eight species of the fungi were detected, but in darkness only five species were found.
3. Pyricularia oryzae was not detected by Agar plate method and in continuous darkness. It was found when incubated under light and darkness. The near ultraviolet was more effective than the artificial day light.
4. Trichoconis padwickii was detected by Agar plate method. Otherwise, the fungi showed the same results as Pyricularia oryzae.
