摘要:

从福建漳州九湖乡水仙大田水仙根际分离并筛选到对水仙叶大褐斑病有明显拮抗作用的菌株CS5、CS51、CS121。通过个体形态、培养特征、生理生化特性研究,将它们分别鉴定为枯草芽孢杆菌(CS5)、蜡质芽孢杆菌(CS51)、荧光假单孢菌(CS121)。3株细菌的DNAG+C摩尔百分比分别为43.7%、39.1%和66.8%。

Abstract: Three isolates antagonistic to Stagonospora curtisii on Narcissus sp.were isolated and selected from fields of Zhangzhou Jiuhu.The morphology, cultivation,physiology,biochemistry and DNA base compositions of these isolates were tested foridentification.CS5 was characterized as Bacillussubtilis, CS51 as B.cereus and CS121 as Pseudomonas fluorescens. Their DNA base compositions were 43.7% ,39.1% and 66.8% respectively.
