2009~2010年从安徽省三大棉区采集病秸秆并分离得到30株棉花黄萎病菌株,通过对其培养性状的测定发现,多数菌株为菌核型,占80.0%,少数为中间型,占16.7%,而菌丝型仅占3.3%。对感病棉花品种苗期致病程度测定结果表明,安徽省黄萎病菌株可划分为强、中、弱3种致病类型,其中致病性强的菌株有7株,占参试菌株的23.3%,中等致病性的菌株有14株,占46.7%,致病性弱的菌株有9株,占30%。研究结果还表明,不同地区棉花黄萎病菌株间的致病程度存在较大差异,同一地区的不同菌株间致病程度也有一定差异。
2009~2010年從安徽省三大棉區採集病秸稈併分離得到30株棉花黃萎病菌株,通過對其培養性狀的測定髮現,多數菌株為菌覈型,佔80.0%,少數為中間型,佔16.7%,而菌絲型僅佔3.3%。對感病棉花品種苗期緻病程度測定結果錶明,安徽省黃萎病菌株可劃分為彊、中、弱3種緻病類型,其中緻病性彊的菌株有7株,佔參試菌株的23.3%,中等緻病性的菌株有14株,佔46.7%,緻病性弱的菌株有9株,佔30%。研究結果還錶明,不同地區棉花黃萎病菌株間的緻病程度存在較大差異,同一地區的不同菌株間緻病程度也有一定差異。

The authors collected diseased straw from three cotton regions of Anhui Province in 2009 -2010 years,30V-erticillium dahliae strains were obtained,through the determination of cultural character,found that most strains were bacteria karyotype,accounted for 80%,A few intermediate type,accounting for 16.7%,but the mycelial type accounted for only 3.3%.In susceptible cotton cultivars showed that the degree of pathogenicity test results,Verticillium dahliae of Anhui prov-ince could be divided into strong,medium,weak 3 different pathogenic types,including 7 strains strong virulence,accounting for 23.3%,14 strains moderate pathogenicity,accounting for 46.7%,9 strains weak pathogenicity,accounting for 30%, The results also showed that there were large differences of the degree of pathogenicity of Verticillium dahliae strains in differ-ent regions,degree of pathogenicity of the same area also had certain difference.
