Abstract

Strains (10705) of microscopic fungi were isolated from spring barley heads in the region of Lublin (south-eastern Poland). Fusarium sporotrichioides Sherb was found in 418 (3.9%) of isolated strains. Group A trichothecene mycotoxins were detected in the collected barley kernels colonized by F. sporotrichioides, with Fusarium head blight symptoms. Among 24 samples analysed, 12 were T-2 toxin positive in a range of contamination from 0.02 to 2.40 micrograms/g (average 0.45), while in five samples HT-2 toxin ranged from 0.01 to 0.37 micrograms/g (average 0.23) and T-2 tetraol was detected in two samples in a range of 0.01-0.21 micrograms/g (average 0.11). Twelve samples were free of detectable amounts of the toxic metabolites analysed.

摘要

在卢布林地区（波兰东南部）的春大麦穗中分离出了显微真菌菌株（10705）。在418株（3.9%）分离菌株中发现了拟枝孢镰刀菌。在收集到的出现镰刀菌穗腐病症状且被拟枝孢镰刀菌定殖的大麦籽粒中检测到了A组单端孢霉烯族霉菌毒素。在分析的24个样本中，12个样本的T-2毒素呈阳性，污染范围为0.02至2.40微克/克（平均0.45），而在5个样本中，HT-2毒素范围为0.01至0.37微克/克（平均0.23），在2个样本中检测到T-2四醇，范围为0.01 - 0.21微克/克（平均0.11）。12个样本未检测到可分析的有毒代谢物。
