The Fusarium diversity and the mycobiota associated with moldy wheat kernels from Santa Fe province, Argentine, was assessed. The wheat cultivated area in Santa Fe province is divided according to agrometeorological conditions into two zones: Zone I (north-central) and Zone II (south). The natural occurrence of Fusarium toxins BEA, FUP, DON and NIV was also determined. Cladosporium was the most abundant of the 19 genera identified, followed by Fusarium, Phoma and Alternaria. Zone II shows a predominance of F. graminearum and F. culmorum. In Zone I, DON was present in 13/32 samples (range 0.43-3.60 mg kg(-1)) and NIV in 6/32 samples (range 0.11-0.40 mg kg(-1)). In zone II, DON was found in 11/21 samples (range 0.57-9.50 mg kg(-1)) and NIV in 4/21 samples (range 0.10-0.60 mg kg(-1)). BEA and FP were not detected in both zones.
对来自阿根廷圣达菲省霉变麦粒中的镰刀菌多样性及其相关真菌群落进行了评估。根据农业气象条件，圣达菲省的小麦种植区分为两个区域：区域 I（中北部）和区域 II（南部）。还测定了 BEA、FUP、DON 和 NIV 等镰刀菌毒素的自然发生情况。在鉴定的 19 个属中，枝孢菌最为丰富，其次是镰刀菌、茎点霉和交链孢霉。区域 II 以禾谷镰刀菌和层出镰刀菌为主。在区域 I 中，有 13/32 个样品（范围 0.43-3.60 mg kg(-1)) 含有 DON，有 6/32 个样品（范围 0.11-0.40 mg kg(-1)) 含有 NIV。在区域 II 中，有 11/21 个样品（范围 0.57-9.50 mg kg(-1)) 含有 DON，有 4/21 个样品（范围 0.10-0.60 mg kg(-1)) 含有 NIV。两个区域均未检测到 BEA 和 FP。
