蚕豆根腐病病原菌的研究
首发时间:2006-06-22
摘要:根腐病是由多种病原菌引起,通过分离、鉴定,共获得三种镰刀菌,其分别为燕麦镰孢(Fusarium avenaceum)、尖孢镰孢(Fusarium oxysporum)、茄镰孢(Fusarium solani)。获得三种非镰刀菌,其分别为曲霉属(Aspegillus Micheli)、青霉属(Penicillium)、链格孢(Alternaria sp)等。通过致病性测定,证实了燕麦镰孢(Fusarium avenaceum)、尖孢镰孢(Fusarium oxysporum )、茄镰孢(Fusarium solani)均为蚕豆根部病害的主要致病病原菌。而链格孢(Alternaria sp)也为蚕豆根部病害的致病病原菌。

Studied on pathogens of fababean root rot
Abstract:Fababean root rot is infected by many pathogens ,three Fursarium strains are obtained by islated and identificated. The Fursarium islates include Fusarium avenaceum, Fusarium oxysporum ,Fusarium solani.And three other fungi are obtained ,too.There are Aspegillus Micheli, Penicillium, Alternaria.sp,the virulence of Fusarium avenaceum, Fusarium oxysporum,Fusarium solani is strong, the result showed that the three species are the main pathogen of fababean root rot.However,Alternaria sp is pathogen of fababean root rot,too.
Keywords: fababean root rot Fusarium Alternaria
