| 摘 要： | 从不同地区不同松树上采集分离不同种类的线虫,对线虫携带的细菌进行分离鉴定,并用黑松无菌苗及愈伤组织测定细菌的毒性.细菌分离结果表明:松材线虫携带的优势菌为荧光假单胞菌,与其他线虫携带的细菌种类不同.毒性测定结果显示:松材线虫携带的优势菌株毒性最强,拟松材线虫及滑刃属线虫携带的细菌具有一定程度的毒性,小杆线虫携带的细菌没有任何毒性.结果进一步证明了松材线虫携带的细菌在其致病过程中发挥着重要作用. |

| Abstract: | The bacteria carried by different nematodes which were collected and isolated from xylem of infected pine trees of Pinus genus in different areas were identified.The toxicity of culture liquid of these bacteria was tested with seedlings and callus tissue of Pinus nigra.The results indicated that the predominant bacterium species carried by pine wood nematode was Pseudomonas fluorescens,which was different from bacteria species carried by other nematodes.The toxicity of the predominant bacterium carried by pine wood nematode was the most virulent,while toxicity of the bacteria carried by Bursaphelenchus mucronautus and Aphelenchoides sp.nematode were moderately virulent.The bacterium carried by Rhabditida sp.nematode was not toxic.The results farther showed that the bacteria carried by pine wood nematode would play an important role in the pathogenic process. |
