| 摘 要： | 近年来雪松枝枯病在河北省发生严重,致使雪松枝条,甚至主干枯死,严重影响景观.为控制雪松枝枯病的发生和蔓延,对保定地区雪松枝枯病害进行了研究.通过组织分离出雪松枝枯病病原,并对其进行了致病性测定,根据培养性状和形态特征鉴定其病原菌是球壳孢目(Sphaeropsidales)小穴壳菌(Dothiorella sp.).该菌能在多种碳源中生长,但在麦芽糖培养基中生长最快;在氮源培养基中,蛋白胨培养基最适宜其生长.野外调查表明,此病害与人为活动有紧密关系:人为活动频繁,管理粗放,病害发生严重. |

| Abstract: | An experiment was conducted to study the branch withering of cedar in order to control the occurrence and spread of the disease in Baoding City.The pathogen of branch withering of cedar was isolated and identified as Dothiorella sp.of Sphaeropsidales according to its cultural and morphological characters.The Dothiorella sp.could grow on culture media containing various carbon sources,but grew the fastest on medium containing maltose.The suitable culture medium containing nitrogen sources was peptone medium.... |
