| 摘 要： | 对定西李家堡镇、十八里铺镇、巉口镇的小扁豆根腐病植株进行了分离,得到了130株镰刀菌单孢株系,经鉴定为6个种,其中尖孢镰刀菌100株,所占比例最大,为76.96%,茄病镰刀菌、串珠镰刀菌、木贼镰刀菌、接骨木镰刀菌、锐顶镰镰刀菌所占比例分别为9.00%、7.00%、3.90%、0.70%、3.08%。盆栽致病性测定结果表明尖孢镰刀菌、茄病镰刀菌、串珠镰刀菌和木贼镰刀菌都有致病性,是小扁豆根腐病的病原菌,其中尖孢镰刀菌为优势病原菌,并且茄病镰刀菌、串珠镰刀菌和木贼镰刀菌作为小扁豆根腐病病原在国内首次报道。幼苗接种结果表明小扁豆在发芽第8 d发病率最高,在胚根中部和基部侵染率高。

| Abstract: | Lentil root diease samples were obtained from dingxi of Gansu,and 130 monoconidial Fusarium strains were isolatednm.have been identified as 6 species of Fusarium,isolations of F.oxysporum were majority with the rate of 76.9%,F.solani,F.moniliforme,F.acuminatum,F.equiset,F.sambuimum were 9.00%,7.00%,3.90%,0.70%,3.08%.the result of Pathogenicity Test showed that F.oxysporum had the highest pathogenicity Inocated,at the different site of stem,the result showed that it is easy to infected by pathogenic fusarium... |
