| 摘 要： | 菌丝融合型测定结果表明，32个茭白纹枯病菌菌株隶属于两个菌丝融合群：30个属AG1群，占测定菌株的93．95％，其中AG1-IA、AG1－IC两亚群菌株依次为24与6，有两菌株为AG4，占6．25％。显然，AG1－IA为优势融合群，占测定菌株的75％。融合群致病性测定结果表明，AG1－IA致病性强，AG1－IC弱，AG4基本不致病。茭白与水稻两种纹枯病菌交互接种，其发病基本一致。由此，作者认为这两种纹枯病菌为同一病原物，或者说茭白、水稻是同一病原物的两个寄主植物。

| Abstract: | Based on the anastomosis group AG tests,32isolates of the water bamboo sheath bright pathogen were identified as3groups:AG 1-IA 24,AG 1-IC 6,and AG 4 2.AG 1-IA got to75%of all iso lates as advan tage group.The test of the different AG pathogenicity demonstrated that AG 1-IA was very strong,AG 1-IC weak,AG 4 very weak,according to disease percentage and length of disease lesion.The cross-infected tests by the isolates AG 1-IA respectively from rice and water bamboo plants showed that both isolates were basically the same in pathogenicity to rice and water bamboo.The authors think that the main pathogen to both rice sheath bright and water bamboo bright was the same. |
