Sycamore maple is a valuable admixture species in many European countries, including Slovakia. As most species belonging to the genus Acer, it is susceptible to several pathogenic organisms including species of Oomycetes. To determine whether the decline of Acer pseudoplatanus in Slovakia is caused by pathogenic Oomycetes, soil samples were taken from the rhizosphere in three sycamore maple stands. Isolation from leaf baits and subsequent identification based on sequencing of the ITS showed the presence of three species: Pythium intermedium, Phytophthora plurivora and Phytophthora obscura. This is the first report on the occurrence of P. plurivora and P. obscura in the rhizosphere of declining sycamore maple stands in Slovakia.

斯洛伐克Acerpseudoplatanus Phytophthoraobscura 发生的首次报告

在包括斯洛伐克在内的许多欧洲国家，梧桐枫是一种有价值的混合树种。作为属于Acer属的大多数物种，它对包括卵菌纲在内的几种病原生物敏感。为了确定斯洛伐克Acer pseudoplatanus的衰退是否由致病卵菌引起，从三个梧桐枫林的根际采集土壤样本。从叶诱饵中分离出来并随后基于 ITS 测序进行的鉴定表明存在三个物种：中间腐霉、多食疫霉和暗黑疫霉。这是关于P发生的第一个报告。 多食性和P。 在斯洛伐克，正在衰退的梧桐树根际中的暗箱。
