近年来,在河南省洛阳市多年生的牡丹枝条上多次发现枝枯病症状。为明确病原种类,试验对采自田间的典型病枝进行组织分离,对所得菌株进行了形态鉴定、DNA序列分析及致病性测定。结果表明,引起洛阳市牡丹枝枯病的主要病原菌为头状茎点霉(Phomaglomerata)。 In recent years, the symptoms of shoot blight have been found on peony shoots perennial in Luoyang, Henan Province. In order to clarify the species of pathogen, the typical diseased branches collected from the field were isolated by tissue culture. The obtained strains were identified by morphology, DNA sequence analysis and pathogenicity test. The results showed that the main pathogen causing Peony blight in Luoyang was Phomaglomerata.
