摘要
‘鹰嘴蜜桃’是广东的一个特色桃品种,以广东的连平县种植面积最大,但自2008年以来,桃树流胶病严重影响当地‘鹰嘴蜜桃’产业的发展,成为桃生产中的一大病害。为明确广东‘鹰嘴蜜桃’流胶病的病原菌种类,通过病原菌的分离和致病性回接试验,并采用形态学鉴定方法结合基于rDNA-ITS、β-tubulin和TEF1-α基因序列分析的分子鉴定方法对病原菌进行了鉴定。结果表明,引起广东‘鹰嘴蜜桃’流胶病的病原菌为Botryosphaeria dothidea(无性态Fusicoccum aesculi)。
‘Yingzuimitao'is a characteristic peach cultivar in Guangdong Province,and Lianping is the largest county in planting area.However,since 2008,the development of‘Yingzuimitao'industry in Lianping has been seriously affected by peach tree gummosis,a destructive disease.Through pathogen isolation and pathogenicity test,combining morphological identification with molecular identification based on rDNA-ITS,β-tubulinand TEF1-αgene sequence analysis,the pathogen was identified as Fusicoccum aesculi,the anamorph of Botryosphaeria dothidea.
