摘要: 为明确湖北省蔬菜产区镰孢菌(Fusarium spp.)的种类及分布特征,本研究从湖北省13个地级市蔬菜产区采集根际土壤样品55份,对土样中的镰孢菌进行分离、纯化和鉴定,获得271株镰孢菌;通过镰孢菌特异性引物扩增、测序等分子生物学技术,鉴定出尖孢镰孢菌(F. oxysporum)118株,占分离菌株43.6%;木贼孢菌(F. equiseti)46株,占17.0%;共享镰孢菌(F. commune)45株,占16.6%;茄病镰孢菌(F. solani)31株,占11.4%;藤仓镰孢菌(F. fujikuroi)11株,占4.1%;镰孢霉菌(F. delphinoides)6株,占2.2%;轮纹镰孢菌(F. concentricum)5株,占1.8%;三线镰孢菌(F. tricinctum)3株,占1.1%;镰孢菌属(Fusarium spp.)6株,占2.2%。通过与致病菌尖孢镰孢菌番茄专化型(F. oxysporum f. sp. lycopersici)菌株进行对峙培养,筛选出拮抗镰孢菌16株,包括尖孢镰孢菌(F. oxysporum)4株,茄病镰孢菌(F. solani)4株,轮纹镰孢菌(F. concentricum)3株,三线镰孢菌(F. tricinctum)3株,木贼孢菌(F. equiseti)和藤仓镰孢菌(F. fujikuroi)各1株。本研究明确了湖北省蔬菜产区的镰孢菌属真菌的种类和多样性特征,为蔬菜镰孢菌病害的防治提供科学依据。

Abstract: To clarify the species and distribution of Fusarium species in vegetable growing areas in Hubei province,55 rhizosphere soil samples were collected from 13 cities of Hubei province,and Fusarium species strains from the samples were isolated,purified and identified. Total 271 Fusarium strains were obtained. Among these Fusarium strains,according to molecular biological techniques such as species-specific primers and sequencing,118 strains were identified as Fusarium oxysporum accounting for 43.6% of the total,46 strains as F. equiseti for 17.0% of the total,45 strains as F. commune for 16.6% of the total,31 strains as F. solani for 11.4% of the total,11 strains as F. fujikuroi for 4.1% of the total,6 strains as F. delphinoides for 2.2% of the total,5 strains as F. concentricum for 1.8%,3 strains as F. tricinctum for 1.1%,and 6 strains were Fusarium spp. for 2.2% of the total. Based on the confrontation culture with pathogenic F. oxysporum f. sp. lycopersici strain,16 strains of antagonistic Fusarium species were identified,including 4 strains of F. oxysporum,4 strains of F. solani,3 strains of F. concentricum,and 3 strains of F. tricinctum,while each of F. equiseti and F. fujikuroi was only one,respectively. In this study,the species and diversity of Fusarium species in vegetable producing areas of Hubei province were confirmed,which provides the theoretical basis for the accurate pathogen identification and scientific control of Fusarium disease.
