信阳杉木内生真菌种类研究

Studies on the Species of Endophytic Fungi from Cunninghamia lanceolata in Xinyang Area

摘要: 通过组织分离及物种鉴定，对信阳杉木内生真菌种类进行了研究．得到丝孢纲(Hyphomycetes)和腔孢纲(Coelomycetes)真菌4 科12 属15 种．淡色孢科(Moniliaceae)3 属5 种，暗色孢科(Dematiaceae)2 属2 种，黑盘孢(Melanconidaceae)2 属 3 种，球科孢科(Sphaeropsidaceae)5 属 5 种，这些真菌均为半知菌，是杉木内生真菌首次记载．其中，拟茎点霉 Phomopsis sp．、球刺盘孢菌 Colletotrichum coccodes 分布于杉木各样地各官，为杉木内生真菌广布种．

Abstract: By tissue isolation and species identification, the species of endophytic fungi from Cunninghamia lanceolata were studied in Xinyang area. The results showed that total of 15 fungal species among 12 genera belonging to 4 families and 2 classes, Hyphomycetes and Coelomycetes, were obtained. Five species belonging to 3 genera in Moniliaceae, two species belonging to 2 genera in Dematiaceae, two species belonging to 3 genera in Melanconidaceae and five species belonging to 5 genera in Sphaeropsidaceae were reported. All the fungal species described belonged to Deuteromycotina and they were recorded for the first time as endophytic fungi in Cunninghamia lanceolata tissues. It was also found that the Colletotrichum coccodes and Phomopsis sp. distributed in every organ and every sample plot, they were dispersed species of endophytic fungi in Cunninghamia lanceolata plants
