摘　　要：抗赤霉病小麦品种苏麦3号、繁9能转化镰刀菌毒素脱氧雪腐镰刀菌烯醇(DON)成产物X,而感病小麦品种宁麦6号、徐州21无转化能力。产物X对小麦黄化芽鞘的伸长生长无抑制作用,而对禾谷镰刀菌分生孢子的萌发有明显抑制。说明抗性小麦品种对赤霉病菌毒素的脱毒是小麦重要的抗赤霉病机制。The extracts of leaves in scab resistant wheat varieties, Sumai 3 and Fan 9, decompose Fusarium toxin deoxynivalenol to compound X, but no obvious conversion effect was observed in scab susceptible varieties, Ningmai 6 and Xuzhou 21. Compound X had no effect no growth of wheat coleoptile tissue but can inhibit the spore germination of Fusarium graminearum Schw. The results support that the detoxification of deoxynivalenol is the important scab resistant mechanism in wheat.
