Abstract
담수표면산파와 이앙재배 조건에서 benzobicyclon에 대한 총체 사료용 벼 4품종 및 계통의 약해 반응 차이를 검토한 결과는 다음과 같다. 목우는 모든 재배양식, 처리온도, benzobicyclon 처리량에서 100% 백화 증상을 보였다. 녹양, 목양, 수원560은 benzobicyclon 기준량 처리에서는 백화 증상이 나타나지 않거나 매우 경미하였다. 그러나 benzobicyclon 배량 처리에서 이들 3품종 및 계통은 담수표면산파의 경우 백화 현상이 0-8% 발생하였고, $27^{\circ}C$의 고온 처리에서는 초장의 단축 정도가 컸다. 이앙재배의 경우 이들 3품종 및 계통은 평균기온 $18^{\circ}C$와 $21^{\circ}C$에서 백화 증상을 보이지 않았던 반면, $24^{\circ}C$와 $27^{\circ}C$에서는 품종에 따라 2-32%의 백화증상을 나타내었고 건물중도 감소하는 경향을 보였다. Benzobicyclon 배량의 고온처리에서 이와 같은 약해 증상은 일반형 품종인 일품에서도 나타났다. 결과적으로, 목우는 benzobicyclon에 대한 약해가 매우 심하였으며, 녹양, 목양, 수원560은 benzobicyclon 기준량 처리에서는 약해를 보이지 않았다. Benzobicyclon induces phytotoxicity to Tongil type rice, although it is an efficient herbicide in paddy. This study was performed to figure out the benzobicyclon-induced phytotoxicity responses of whole crop forage rice genotypes that have the genetic background similar to Tongil type rice, under wet-seeded and transplanted conditions. Mogwoo demonstrated whitening symptom at all the temperatures in both wet-seeding and transplanting by the application of standard and double rates of benzobicyclon. Nokyang, Mogyang and Suweon560 exhibited no or negligible whitening and their plant heights were not reduced at standard rate of benzobicyclon. But in double rate application in wet-seeding, the three genotypes showed 0-8% of white plants at all temperature treatments and reduction in plant height was comparatively larger at $27^{\circ}C$. In transplanting, the double rate application of benzobicyclon at 24 and $27^{\circ}C$ induced 0-32% of whitening plants depending on genotypes while no whitening plants were observed at 18 and $21^{\circ}C$ in all genotypes. Reduction in biomass by double rate of benzobicyclon at 24 and $27^{\circ}C$ was greater than at 18 and $21^{\circ}C$. It is concluded that Mogwoo is extremely sensitive to benzobicyclon and Nokyang, Mogyang and Suweon560 are tolerant to the standard rate of benzobicyclon.
