Abstract

The objectives of the study were to assess the infection level of Fusarium head blight (FHB) in different spring barley and oat cultivars and to specify the spectrum of Fusarium species of Latvian population found in the ear samples of spring barley and oat. Molecular analysis of single-conidium isolates of Fusarium species from the grain samples in different sites of Latvia revealed the presence of F. acuminatum, F. avenaceum, F. boothii, F. culmorum, F. graminearum, F. poae, F. sporotrichioides, and F. tricinctum in Latvian population of Fusarium species associated with FHB in spring barley. F. avenaceum, F. culmorum, F. equiseti, F. graminearum, F. langsethiae, F. oxysporum, F. poae, F. redolens and F. sporotrichioides were identified in the samples of oat. Further investigations are required.

拉脱维亚小谷物上镰刀菌的发生。
本研究的目的是评估不同春大麦和燕麦品种的镰刀菌头枯病(FHB)感染水平,并确定在春大麦和小麦穗部样本中发现的拉脱维亚群体镰刀菌的种类谱。从拉脱维亚不同地点的谷物样品中分离出的镰刀菌单分生孢子的分子分析表明,在与春大麦FHB相关的拉脱维亚镰刀菌种群中,存在尖锐镰刀菌、燕麦镰刀菌(F.avenaceum)、短柄镰刀菌属(F.boothii)、秆镰刀菌目(F.tumorum)、禾谷镰刀菌纲(F.graminearum)、薄孢镰刀菌科(F.poae)、孢子虫样镰刀菌和三尖镰刀菌。燕麦样品中鉴定出燕麦F.avenaceum、F.tumorum、F.equiseti、F.graminearum、F.langsethiae、F.oxysporum、F.poae、F.redolens和F.sporotrichioides。需要进一步调查。
