摘要: 从剑麻叶片组织内分离获得6株内生细菌,其中JM-3菌株对离体苹果枝条上苹果腐烂病菌的扩展致病有较好的抑制效果。JM-3菌株在培养过程中能产生抑菌物质,其无菌发酵滤液能抑制腐烂病菌菌丝的生长和分生孢子的萌发,导致菌丝和芽管膨大畸形,最终导致菌丝破裂、原生质外流。JM-3菌株对多种果树和农作物病原真菌菌丝的生长都有明显的抑制作用。经16S rDNA序列分析和RiboPrinter分析,鉴定菌株JM-3为枯草芽孢杆菌。

关键词: 内生细菌, 枯草芽孢杆菌, 苹果腐烂病

Abstract: Six isolates of endophytic bacterial strains were isolated from healthy leaves of Agavesisalana Per- rine,in which the strain JM- 3 inhibited canker lesion expansion of Valsa ceratosperma on excised twigs significantly. The cell- free fermentation liquid of JM- 3 inhibited mycelium growth and conidial germination of Valsa ceratosperma. The isolates produced anti- fungi substances,which caused malformation of mycelia and germtubes.The malformed mycelium burst and protoplasm flow- out finally.JM- 3 also showed clear inhibiting effect against mycelial growth of pathogen from several fruit trees and crop.JM- 3 was identified as Bacillus subtilis based on 16S rDNA sequencing and RiboPrinter results.

Key words: Endophytic bacteria, Bacillus subtilis, Valsa ceratosperma
