영문 초록

This study was carried out to compare the growth and yield characteristics between bakanae diseases (Gibberella fujikuroi) infected and uninfected rice plants with different disinfection mothods. The infected rice seeds, harvested previous year, were disinfected either with pro-chloraz for 48 hours at 33℃ in germinator or 24 hours at room temperature and not disinfected. In the methods of disinfection, it is more effective in disinfected by pro-chloraz for 48 hours at 33℃ using germinator near to 0% of infection rate, followed by conventional method as 5.0% and 76% in not disinfected rice seeds. In the rice yield components among the disinfection methods, panicles were increased about 11% in the disinfected seeds using ger-minator for 48 hours compared to conventional method. Ripening grain rate also increased at the disinfected using germinator as 80.3~80.3%, improved more than 4.9~5.9% compared to the conventional disinfection. From these results, the rice yield was 512~517 kg/1,000 m2 at the disinfected using germinator which increased more than 6~7% com-pared to the conventional disinfection.
