国内首次发现,碱茅和甜茅可作为条锈菌的寄主。小麦条锈流行小种条中25和22号在北京近郊自然条件下分别侵染碱茅(Puccinellia distans)和纤毛鹅观草(Roegneria ciliaris)。湖北神农架一种甜茅(Glyceria sp.)上的条锈分离菌在小麦条锈鉴别寄主上的毒力范围比条中25号更广:对水源11有毒力,在洛夫林13和牛朱特上能产生具有正常萌发与再侵染功能的夏孢子。推测野生禾草在锈菌新致病类型的发生和维持方面可能有其特殊的意义。
For the first time found in China, alkali Mao and sweet Mao can be used as host of the stripe rust. Wheat stripe rust races 25 and 22 were infested with Puccinellia distans and Roegneria ciliaris, respectively, under natural conditions in the suburb of Beijing. Hubei Shennongjia a sweet grass (Glyceria sp.) Stripe rust isolates in the identification of wheat stripe rust virulence than Article 25 wider: virulent to water 11, Lovrin 13 and cattle Zhu Te On the can produce a normal germination and re-infection function of summer spores. It is speculated that wild grass may have special significance in the occurrence and maintenance of new pathogenic types of rust.
