Abstract:
Taking oil beans in Heilongjiang province as material，the disease was isolated and identificated，and the inhibitory effect of O3，pressure，chitosan and 1-MCP on mycelia growth were studied.The results showed that main pathogens were wild rapeseed yellow aeromonas and bean gray mold pathogen.Bean gray mold could grow well in the neutral and alkaline conditions and were highly sensitive to alkali and acidic environment.Yellow aeromonas grew well in a neutral environment，partial acid or alkali conditions would have the inhibition to the bacteria.The inhibitory action of chitosan on yellow aeromonas and gray mold was conspicuous，and the effect was good when chitosan concentration for 2.0%.The effect of sterilization by 10 minutes ozone treatment on the pathogen was obvious.Reduced pressure could inhibit the growth of pathogens，the inhibiting effect was optimal when the pressure dropped to 40 kPa.1-methyl ring propylene was good preservative.The pathogens inhibitoryeffect was optimal when 1-MCP concentration 40 mg/L.
