A study was made of deoxynivalenol (DON) incidences and levels in 1982 hard red winter (HRW) wheat grown in areas of Nebraska and Kansas known to have scabby wheat. Samples of wheat harvested in the areas were collected from elevators and analyzed for DON by gas chromatography with an electron capture detector. Of the 161 samples analyzed, 42% contained less than or equal to 1 ppm; 68% contained less than or equal to 2 ppm; 90% contained less than or equal to 4 ppm. There were differences in the occurrence of DON in the 5 areas identified in eastern Nebraska and Kansas. The mean level of DON decreased from north to south in these areas in the following order: 2.81, 2.73, 2.05, 1.52, and 0.83 ppm. An area in north central Kansas had a mean level of DON of 0.50 ppm. Correlations were made between DON incidences and levels in HRW wheat and factors used in grading wheat. The occurrence of DON was highly correlated with percent total kernels damaged by mold, percent total defects, and percent total scab damage.
对1982年在内布拉斯加州和堪萨斯州已知有赤霉病小麦的地区种植的硬红冬小麦（HRW）中的脱氧雪腐镰刀菌烯醇（DON）发生率和含量进行了研究。从这些地区的升降机收集收获的小麦样本，并用带有电子捕获检测器的气相色谱法分析DON。在分析的161个样本中，42%的样本含量小于或等于1 ppm；68%的样本含量小于或等于2 ppm；90%的样本含量小于或等于4 ppm。在内布拉斯加州东部和堪萨斯州确定的5个地区，DON的发生率存在差异。在这些地区，DON的平均含量从北到南依次降低：2.81、2.73、2.05、1.52和0.83 ppm。堪萨斯州中北部的一个地区DON的平均含量为0.50 ppm。对HRW小麦中DON的发生率和含量与小麦分级所使用的因素之间进行了相关性分析。DON的发生率与被霉菌损坏的总籽粒百分比、总缺陷百分比和总赤霉病损伤百分比高度相关。
