自全省三个地区新陈小麦、玉米、水稻 170份样品中分离霉菌。共检出串珠镰刀菌及其交孢变种 99株 ,其中新玉米检出 75株占它检出总数的 75 8% ,各样品中伏马菌素 (FB1)检测结果阳性率以陈小麦最高 ,10 0 % ,平均在 3 0 % -63 3 %平均含毒量在 7 90 -9 95mg/kg之间 ,各种样品的平均含毒量相差不大。菌株的FB1测定结果阳性率 10 0 %平均含毒量为 2 6 85mg/kg ,远远高于各样品平均含毒量。 Molds were isolated from 170 samples of fresh wheat, corn and rice in three regions of the province. A total of 99 strains of Fusarium moniliforme and its cross-pollination were detected, of which 75 strains were detected in new maize, accounting for 75.8% of the total. The positive rate of fumonisin (FB1) 10 0%, with an average of 30% -63 3% of the average toxic volume between 7 90 -9 95mg / kg, the average content of various samples or less. The positive rate of FB1 assay was 10 6%, which was much higher than the average of each sample.
