- 摘要:
- 以染病及健康的牛耳枫为试材,采用常规组织分离法对牛耳枫枯梢病病原进行分离,通过对病原菌的形态学特征、致病性测定和rDNA-ITS序列分析,对引起牛耳枫枯梢病的病原菌进行了鉴定。结果表明:牛耳枫枯梢病的病原为尖孢镰刀菌(Fusarium oxysporum),该病原菌直接侵染牛耳枫嫩梢引起枯梢病。
- Abstract:
- Taking healthy and infected Daphniphyllum calycinum as material,the pathogen caused shoot blight of Daphniphyllum calycinum was isolated by general tissue isolation,and identified based on morphological characteristics,pathogenicity test and rDNA-ITS sequences analysis.The results showed that the pathogen caused shoot blight of Daphniphyllum calycinum was Fusarium oxysporum,and F.oxysporum causing shoot blight by directly infecting on Daphniphyllum calycinum.
