安徽省马尾松树干内真菌种类研究

Study on the fungi species in stem of Pinus massoniana in Anhui province

通过组织分离法,对安徽省9县(市)不同健康状态马尾松树干内真菌种类进行了研究。结果表明,不同健康状态马尾松树干均存在大量真菌,笔者分离到长喙壳等24类可鉴定真菌以及一些待鉴定真菌,其中长喙壳和待鉴定菌Ⅰ为木块变色真菌。对不同健康状态马尾松树干内真菌相对检出率进行比较,死亡马尾松中最高,濒死马尾松次之,健康马尾松最低。健康马尾松树干中不存在变色菌,优势真菌为木霉和镰刀菌,濒死马尾松树干优势真菌为待鉴定菌Ⅰ和长喙壳,死亡马尾松树干优势真菌为木霉和待鉴定菌Ⅰ。

Fungi in stem of Pinus massoniana were studied.The results showed that a lot of fungi were isolated and identified.Predominant fungi Ophiostoma sp.and the unidentified fungus isolate Ⅰ were sap stained fungi.The number of fungi species in the died stem of P.massoniana was richer than that in the impending death stem,and more abundant than that in the healthy stem.The population of Ophiostoma sp.and the unidentified fungus isolate Ⅰ in the impending death stem of P.massoniana were more than that in the died stem of P.massoniana.The died stem of P.massoniana had the highest population of Trichoderma spp.,the impending death stem had less,and the healthy stem had the least.
