摘要
Development of deoxynivalenol (DON) in wheat with a low contamination with Fusarium spp. was investigated under suboptimal storage conditions (17% and 20% grain moisture, 20°C). The influence of storage on the relative DNA content of potential DON producers was also determined. The DON contents were quantified using an ELISA. The Tox5 PCR was used for the detection of potential trichothecene producers and for the estimation of their relative DNA content. The gaoA gene was subsequently amplified by PCR to detect specifically Fusarium graminearum. The concentration of F. graminearum DNA was semiquantitatively determined using a Light Cycler™. The DON concentrations increased during storage trials but the intensity of PCR signals decreased.
