벼 이삭마름병에 관여하는 진균의 검출

In order to detect casual agents associated with ear blight of rice, seed samples of 'Ilmi-byeo' and 'Daesan-byeo', susceptible cultivars were collected from 28 regions on a nationwide scale. Finally 23 fungi including Bipolaris oryzae($10.3\%$), Alternaria alternata ($10.2\%$),...

Zusammenfassung:In order to detect casual agents associated with ear blight of rice, seed samples of 'Ilmi-byeo' and 'Daesan-byeo', susceptible cultivars were collected from 28 regions on a nationwide scale. Finally 23 fungi including Bipolaris oryzae($10.3\%$), Alternaria alternata ($10.2\%$), Cladosporium sp. ($7.5\%$), Nigrospora oryzae($5.2\%$) and Phoma sorghina ($6.3\%$) from seeds of 'Ilmi-byeo', and 13 fungi including N. oryzae ($15.1\%$), A. alternata ($9.6\%$) and Curvularia lunata ($2.2\%$) from seeds of 'Daesan-byeo' were detected. In case of discolored seeds caused by rice ear blight, B. oryzae($15.5\%$), A. alternata ($5.5\%$), Fusarium graminearum ($8.0\%$), N. oryzae($5.2\%$) and P. sorghina ($4.5\%$) were detected even from the hulled rice of Ilmi-byeo. 벼 이삭마름병에 관여하는 진균의 종류로 일미벼에서는 Altemaria alternate($10.2\%$), A. padwickii($5.2\%$), Bipolaris oryzae($10.3\%$), Nigrospora oryzae($5.2\%$), Phoma sorghina ($6.3\%$) 등이 우점 하였으며,총 23종의 진균이 검출되었다. 대산벼에서는 A. alternate($9.6\%$), Cladosporium sp. ($7.5\%$), Curvularia lunate($2.2\%$), N. oryzae($15.1\%$) 등이 우점 하였으며, 총 13종의 진균이 검출되었다. 또한 이삭마름병으로 벼알이 심하게 오염된 경우에는 일미벼 현미에서도 B. oryzae($15.5\%$), A. alternate($5.5\%$), Fusarium graminearum($8.0\%$), N. oryzae($5.2\%$), P. sorghina($4.5\%$) 등이 높은 비율로 감염되어 있었다.
