摘要
[目的]为潜山县姜瘟病的防治提供资料。[方法]采集潜山县生姜主产区得瘟病的姜苗样本,用常规方法分离其中的病原体,并对病原体进行细菌学和生物型鉴定。[结果]从所采集样本中共分离出16株菌株(QS1、QS2、QS3、QS4、QS5、QS6、QS7、QS8、QS9、QS10、QS11、QS12、QS13、QS14、QS15、QS16),其中菌株QS2、QS6、QS7、QS10、QS14、QS15的感染症状与青枯罗尔氏菌HS028菌株的感染症状一致,6株致病菌株的培养性状和生理生化反应均与HS028菌株一致;6株致病菌株均能利用甘露醇、山梨醇及甜醇,不能利用麦芽糖、乳糖和纤维二糖。[结论]潜山县生姜瘟病的病原体为青枯罗尔氏菌,且其生物型为Ⅳ型。
[ Objective ] The study was tO provide the data for control of ginger bacterial wilt in Qianshan County. [ Method ] The ginger seed- lings samples with ginger bacterial wilt in major ginger production area ,of Qianshan County were collected. The pathogens in the samples were isolated with routine method, and the bacteriological characteristics and biotype of the pathogens were identified. [ Result] 16 strains （QS1, QS2, QS3, QS4, QS5, QS6, QS7, QS8, QS9, QS10, QS11, QS12, QS13, QS14, QS15, QS16） were isolated from the samples, and the infection symptom of Qs2, Qs6, Qs7, QS10, Qs14 and QS15 were uniform with that of HS028 strain of Ralstonia solanacearum （Smith） Yabuuchi, et al. , the cultural characters and the physiological and biochemical reaction of the 6 pathogenic strains were all uniform with those of HS028. 6 pathogenic strains could use mannitol, sorbitol and duleitol, but could not use maltose, lactose and cellobiose. [ Conclusion ] The pathogens of ginger bacterial wilt in Qianshan County were R. solanacearum,and their biotypes was Ⅳ.
