摘要: 为筛选适用于内蒙古地区马铃薯晚疫病的生物防治菌株,从内蒙古西部荒漠地区土壤中获得一株具抑制马铃薯晚疫病致病疫霉的菌株,经16SrDNA序列分析,该菌株为Brevibacillusformosus的近缘种,同源性为99.85%。通过平板对峙实验、马铃薯叶片离体实验及马铃薯块茎离体实验证实,该菌株对致病疫霉具有良好的抑制效果,具有进一步研究的价值。

Abstract: In order to screen the biocontrol strains suitable for the late blight of potato in Inner Mongolia,a strain with pathogens resistant to Phytophthora infestans was obtained from the desert soil of western Inner Mongolia.The strain was analyzed by 16S rDNA sequence and it was near Brevibacillus formosus.The results showed that the strain had good inhibitory effect on Phytophthora infestans by plate experiment,potato leaf in vitro experiment and potato tuber in vitro experiment,and had further research value.
