中文摘要：

研究呕吐毒素在不同种类玉米和玉米颗粒结构中的污染分布规律。采用酶联免疫快速检测法测定粉质玉米、胶质玉米及玉米颗粒不同结构（皮、胚、胚乳）中呕吐毒素含量，同时研究不同霉变率玉米样品、不完整粒率玉米样品筛上物和筛下物与呕吐毒素含量间的相关性。结果表明：完整玉米子粒中，呕吐毒素均主要分布在玉米种皮中；在不同霉变率的玉米中，呕吐毒素在霉变率高的玉米中含量较高；在含有不完善粒的玉米中，呕吐毒素在其筛下物中含量较高。本研究为定向脱霉处理、提高玉米利用率和选购较低呕吐毒素含量的玉米提供一定的参考依据。

英文摘要：

The aim was to study distribution of deoxynivalenol contamination in different parts and different kinds of corn. Enzyme-linked immunosorhent assy（ELISA） was used for determining the contents of deoxynivalenol in colloid corn and flour corn grain （corn structure： testa, embryo and endosperm）, and the distribution of deoxynivalenol in moldy corn and in oversize and undersize of imperfect corn. The results showed that in the whole corn kernel, the deoxynivalenol was mainly distributed in testa; in midew corn, the deoxynivalenol had more contents in higher mould; in imperfect corn, the contents of oversize had more deoxynivalenol than undersize. This survey provided a reference to take off the myeotoxin,to improve the utilization rate of corn and to choose the corn of low deoxynivalenol content.
