【摘要】 用薄层层析法调查厂安徽省１９８３～１９９１年小麦、玉米、大麦及面粉（标准粉）中脱氧雪腐镰刀菌烯醇（ＤＯＮ）的污染水平及其影响因隶。其分析样品６７２件，ＤＯＮ阳性率为６３．２％，平均含量为９０８．７μｇ／ｋｇ，范围在０～１３３３０μｇ／ｋｇ。其中以小麦和面粉污染比较严重，明显高于玉米中ＤＯＮ的水平（Ｐ＜０．０１）。小麦中ＤＯＮ的污染水个个同年度和地区间差异有非常显著性（Ｐ＜０．０１），经方差分析，提示与该年度和地区小麦赤霉病的流行程度有关，但玉米中ＤＯＮ污染水平不同年度和地区间差异均无显著性（Ｐ＞０．１０）。更多还原

【Abstract】 ontamination of deoxynivalenol (DON) in wheat,corn,barley,and wheat flour produced in Anhui Province were examined with thin一layer chromatograpliy in 1983一1991.In total,672 specimens were determined, and 63.2%of them were contaminated by DON, with an average contents of 908.7μg / kg(a range of 0～13330 μg/kg) The contamination of DON in wheat and wheat flour was more severe than that in corn(P<001). There was highly significant difference in the contamination of DON in wheat produced in different areas and vears,with a p一value less than 0.0 1 by ANOVA, but no significant difference in corn(P> 0,1). It suggested the contamination of DON correlated with the inci-dence of scabby wheat in that area during these years.更多还原
