一株放线菌对辣椒青枯菌的拮抗作用及其鉴定
Screening and Identification of an Actinomycete Antagonistic to Pepper Bacterial Wilt
摘要
Abstract
In order to obtain actinomyces strains strongly antagonistic to pepper bacterial wilt,this experiment isolated actinomyces from healthy plant rhizospheric soil of heavier tobacco and pepper bacterial wilt disease fields. One strain (M3-3 was screened out using plate stand-opposite culture method. The average antibacterial circle diameter was up to 42. 73 mm, 38. 80 mm and 32. 60 mm after 24,48,72 hours of cultivation. Combining 16S rDNA sequence analysis and morphological features of colonies, mycelia, spores and spore chains, the strain was identified as Streptomyces lavendulae.关键词
