从小黑麦种子中分离得到的12种镰刀菌20株，对14种冬季谷物（小黑麦、小麦和黑麦）的幼苗进行了致病性试验。致病性最高的接种物是所有菌种分离物的混合物（复合分离物）。致病性最强的菌种分别为：avenaceum、culmorum、sambucinum var. coeruleum和graminearum。冬季小黑麦对幼苗枯萎病的抗性比黑麦强，但对幼苗枯萎病的敏感性比小麦高。用4种镰刀菌（镰刀菌、镰刀菌、谷草镰刀菌和蓝斑镰刀菌）复合分离物接种31个冬稻品种和12个春稻品种的穗部反应进行了研究。与其他同类谷物相比，冬小麦和春小麦最易感染，而冬黑麦的反应与冬小黑麦相当。春季和冬季小黑麦品种对头部侵染反应中等。冬黑麦和小黑麦对镰刀菌侵染的幼苗反应与穗部反应无显著相关。冬小麦呈负相关趋势。上述结果表明，苗期筛选不能用于预测小麦对疫病的抗性。然而，在这一阶段，抗性是非常可取的，以防止由于镰孢菌引起的幼苗枯萎病对作物造成过度损害。
Pathogenicity of 20 isolates of 12 Fusarium species recovered from triticale seed against seedlings of 14 varieties of winter cereals (triticale, wheat, and rye) was tested. The most pathogenic inoculum was a mixture of isolates (a composite isolate) of all the species. The following species were individually the most pathogenic: F. avenaceum, F. culmorum, F. sambucinum var. coeruleum, and F. graminearum. Winter triticale was more resistant to seedling blight than rye but more susceptible than wheat.Also reactions of 31 winter and 12 spring varieties of cereals to head inoculation with a composite isolate of 4 Fusarium spp. (F. avenaceum, F. culmorum, F. graminearum, and F. sambucinum var. coeruleum) was studied. In comparison to other cereals of similar type winter and spring wheat appeared to be the most susceptible while winter rye reaction was comparable to winter triticale. Spring and winter triticale varieties responded to head infection intermediately.There was no significant correlation between seedling and head reactions to infection with Fusarium spp. for winter rye and triticale. For winter wheat a negative trend was found. The above findings imply that screening of cereals at the seedling stage can not be used to predict the resistance to head blight. Nevertheless, resistance at the stage is highly desirable to prevent excessive damage of the crops due to the seedling blight incited by Fusarium spp..
