摘　　要：黄化小麦芽鞘生物测定法是一种敏感的生物测定方法,可用于探测禾谷镰刀菌(Fusariumgraminearum)所产生的毒素的生物活性和不同小麦品种对这些毒素的反应。不同毒素的生物活性与不同小麦品种对毒素的反应均有显著差异,以deoxynivalenol的生物活性最强,抗赤霉品种望水白对供试7种毒素的敏感性最低。试验对毒素与品种之间的相互作用也作了初步研究。A sensitive plaint biassay,etiolated wheat coleoptile biassay,was used to detect biological activity of mycotoxins produced by Furarium graminearum and response of various wheat varieties to these mycotoxins.The significant difference was presented between mycotoxins and between wheat cultivars.The biological activity of deoxynivalenol was strongest and the sensitivity of wheat cultivar,Wang Suibai,to seven te sted mycotoxins was the lowest.The interac- tion of mycotoxins and wheat cultivars preliminarily studied.
