| 摘 要： | 采用田间判断小麦赤霉病的发病级别或者检测刚收获小麦的病粒率,分析小麦赤霉病田间发病级别与其麦粒脱氧雪腐镰刀菌烯醇(DON)含量之间以及病粒率与麦粒DON含量之间的关系,结果表明它们之间都有极显著的相关性。小麦田间发病级别为2级以上时,麦粒的DON含量> 1000μg/kg,4级以上时,麦粒的DO N含量> 2000μ g/kg;在病粒率< 25%时,DO N含量< 1200μg/kg,病粒率在25%~40%时,DON含量为1200~2200μg/kg,病粒率> 40%时,DO N含量> 2200μg/kg。#br#本研究采用卫生部食品卫生监督检验所建立的薄层色谱分析法测定样品中的DON含量,DON平均回收率为91.2%。

| Abstract: | On
basis of the disease grade of wheat scab (DGWS) or disease grain rate of wheat scab estimated
after harvest,the author analysed the relationship between DGWS and DON contents of wheat
grain.Results showed that the relationship in both cases were very significant.When the
disease grade reached more than No.2,the DON content of the wheat grain were more than 1000
g per kg; When the disease grade was more than No.4 , the DON content of wheat grain reached
more than 2000 g per kg.When the DGWS reached less than 25%,the DON content of wheat
grain was less than 1200 g per kg;the disease grain rate of wheat scab was 25%-40%,the DON
content of wheat grain was 1200-2200 g per kg, and the disease grain rate reached more than
40%,the DON content of wheat grain was more than 2200 g per kg. |
