Biocontrol Efficacy of A Paenibacillus polymyxa Strain against Black Rot of Sweet Potato and Its Action Mechanism
摘要
Abstract
Paenibacillus polymyxa XZ-2 is a biological control strain isolated from the healthy soybean plants. The biocontrol efficacy of XZ-2 against black rot of sweet potato and its action mechanism were explored. The results showed that:in comparison with the control (pure water),treating the stored sweet potatoes with the 10~100-fold diluent of XZ-2 fermentation broth could very significantly reduce the scab volume of black rot;among all treatments,the 10-fold diluent of XZ-2 fermentation broth had the best control efficacy against black rot of sweet potato,reaching 73.62%;the treatment with the diluent of XZ-2 fermentation broth had no obvious influence on the hyphal morphology of sweet potato black rot pathogen (Ceratocystis fimbriata),but it could cause the generation of chlamydospores,and could significantly inhibit the germination of conidia of this pathogen.关键词
