Abstract:
Seeds of (Cucurbita maxima) from market were detected for bacterial fruit blotch (BFB) by polymerase chain reaction (PCR) technology.To select the best treatment for seed disinfection,CuSO4,HCl,H2O2,peroxyacetic acid and bleaching powder with different concentrations treated the seeds-borne BFB.The effect of different agentia treatment on the disinfection of pumpkin seed rot pathogen was studied.The results showed that：BFB was detected in 5 different kind of seeds from market.In our study，all 5 treatments with different concentrations had bactericidal effect.However，HCL，H2O2 and peroxyacetic acid also had inhibitory effects on the germination of pumpkin seeds.1.0% CuSO4 with 30 minutes treatment and 1.5% bleaching powder with 30 minutes treatment achieved the best effect on BFB inhibition，and had no effect on seed germination.So，after 1.0% CuSO4 with 30 minutes treatment or 1.5% bleaching powder with 30 minutes treatment，BFB carried by pumpkin seeds could be effectively inhibited.
