摘要:
以猕猴桃溃疡病菌为试菌，采用液体共培养法和含菌抑菌圈法,研究了链霉菌SY-L12对猕猴桃溃疡病菌的生长抑制作用，并测定链霉菌发酵液对猕猴桃溃疡病的盆栽防效。结果表明：链霉菌SY-L12在培养24 h后其发酵液原液对病原菌的生长抑制率达94.0%，在28 ℃、150 r?min-1培养8~9 d条件下最利于活性物质的生产，发酵产物对猕猴桃溃疡病的盆栽防效为85.4%，优于氢氧化铜对照药剂。表明链霉菌SY-L12能够有效抑制猕猴桃溃疡病菌生长，作为生物农药具有开发应用前景。
Abstract:
Pseudomonas syringae pv.actinidiaeas was used as test fungi，the inhibition effect of Streptomyces.sp SY-L12 on Pseudomonas syringae pv.actinidiae was assessed by using co-culture and inhibition-zone methods.Then the control effect was studied in potted trails.The results showed that Streptomyces.sp SY-L12 inhibited the growth of Pseudomonas syringae pv.actinidiae with the inhibitory rate 94.0%.The best efficacy was found when Streptomyces.sp SY-L12 was grown at 28 ℃ with shaking at 150 r?min-1 for 8-9 days,the efficacy of fermentation broth was 85.4% which was higher than the control in potted trails.Therefore Streptomyces.sp SY-L12 might be considered as a new option for developing new integrated control strategies to reduce the disease.
