| 摘要: |
| 用条形柄锈菌大麦专化型（Puccinia striiformis West.f.sp.hordei）的3个代表性菌系，对8个族的25属61种禾草进行了温室人工接种。发现寄主9属22种，除星星草（Puccinellia tenuiflora）属于早熟禾族外，其余均属于小麦族。大麦属（Hordeum）所有参试种均可被侵染，多数高感，大麦是主要寄主。旱麦草属（Eremopyrum）植物和簇毛麦（Haynaldia villosa）也较感病。小麦族的赖草属（Leymus）、鹅观草属（Roegneria）和Thinopyrum属的所有参试种均为免疫或近免疫。 |

| Abstract: |
| Artificial inoculation to 61 grass species of 25 genera belonging to 8 tribes was carried out in greenhouse with 3 representative isolates of Puccinia striiformis West.f.sp.hordei. Twenty-two species of 9 genera were found to be hosts of the fungus. All of them belong to Triticeae except Puccinellia tenuiflora belonging to Poeae. All the tested species of Hordeum were infected,most of them were highly suseeptible. Barley is the main host.The tested species of Eremopyrum and Haynaldia villosa were also susceptible. None of the tested species of Leymus,Roegneria and Thinopyrum in Triticeae were infected. |
