| 摘 要： | 1978~1981年采集54个县市小麦病穗标样,单孢分离获1081菌株。经室内外综合鉴定明确本省引起小麦赤霉病的致病病原有禾谷镰刀菌(Fusarium gra-minearum Schwabe),雪腐镰刀菌F.nival (Fr.) Ces.],本色镰刀菌(F.concolor Rg.),弯角镰刀菌(F.camptoceras Wr.&Rg.),串珠镰刀菌(F.moniliforme Sheld),硫色镰刀菌(F.sulphureum schecht Sacc.)和燕麦镰刀菌草类变种(F.avenaceum var.herberum)。其中禾谷镰刀菌分离频率最高,占绝对优势,分布遍及全省。7个种致病力测定,F=10.48,F> 0.01,不同种致病力差异极显著;禾谷镰刀菌、弯角镰刀菌和硫色镰刀菌致病力最强。

| Abstract: | During 1978-1981,more than 1000 samples collected from scabbed heads of wheat in 54 counties and cities in Fujian province and 1081cultures were obtained by monomaeroconidial isolation.
Based on cultural characters nd inoculation tests on wheat heads,7 pathogenic species were identified,namely,Fusarium graminearum Schwabe;F.nival(Fr.) Ces.;F.concolor Rg.;F.camptoceras Wr.& Rg.;F.monili-forme Sheld;F.sulphureum schleeht Saec.and F.avenaceum var.herberurn,among which F.graminearum was the most prevalent species in Fujian and distributed widely. |
