摘　　要：试验结果表明,烯效唑对小麦黑胚病菌有强烈的抑翻作用,低浓度(5～15mg/kg)烯效唑可抑制黑胚病对黑胚粒发芽、出苗的影响,促进黑胚粒的发芽和出苗;高浓度(20mg/kg)烯效唑则抑制黑胚粒发芽和出苗;用10～15mg/kg烯效唑浸种可预防和防治小麦黑胚病发生。而且幼苗生长旺盛,根系发达。目前河北省推广的小麦品种黑胚率为11.1％,严重者高达42.8％。链格孢菌(Alternaria tenuis)是导致小麦黑胚病发生的主要病原菌,占病原分离物的91.4％。Currently 91. 4% of the black embryo grains in commercial cultivated wheat varieties are caused by Alternaria tenuis. The infection rate of black embryo disease for most commercial wheat varieties is about 11.1% .with a few seriously affected up to 42.8%. Lower concentration uniconazol(5-15mg/kg) can increase germination rate and emergence of the black embryo grains,and improve the seedling growth,while higher concentration uniconazol (20mg/kg) ,on the contrary .inhibit the germination and emergence. Seed soaking with 15mg/ kg uniconazol can also prevent the black embryo disease.
