| 摘 要： | 从典型叶枯病病斑中分离出 3种病原菌 ,经对其病原菌形态、培养性状和致病性等方面的测定表明 ,兰州市草坪草叶枯病主要致病菌为禾草离蠕孢 (Bipolarissarokiniaha) ,其次为狗牙根离蠕孢 (B .cynodontis)。禾草离蠕孢菌在不同品种草坪草中的潜育期不同 ,在感病品种ReblⅡ中的潜育期为 36h ,在抗病品种Raymond中的潜育期为 72h。

| Abstract: | Three isolates are obtained from the typical lesions of leaf blight. The chief pathogen is identified as Bipolaris sarokiniana as through their morphology, isolation culture, test of pathogenicity and retro isolation, etc. Another pathogen is identified as B.cynodontis. The length of latent period was different in different varieties. The latent period is 36h on susceptible variety ReblⅡand 72h on resistance variety Raymond. |
