柑桔叶面真菌区系的初步研究

Epiphytic Mycoflora on Citrus Phylloplane

采用洗涤稀释平板分离法共获得68 株柑桔叶面附生真菌,分属于以下12 个属:Trichoderma, Curvularia , Sirosporium , Cephalosporium , Periconia, Aspergillus, Fusarium , Rhizopus, Alternaria , Phyllosticta , Penicillium ,Cladosporium 。其中链格孢霉( Alternaria sp.),细交链孢霉(A.tenuis),叶点霉( Phyllosticta spp .) ,青霉( Penicillium spp.) ,枝孢霉( Cladosporium spp.) 为叶面优势附生菌。文中,作者还分析比较了叶面附生真菌类群的分布差异。

The species and amount of epiphytic fungi on cirtrus phylloplane were studied by washing and dilution during its growing season in Nanchang, Jiangxi in 1997. 68 isolates were identified and classified into 12 genera of mycetes, including five dominant species of epiphytes Alternaria sp., A. tenuis, Phyllostita spp., Penicillium spp., Cladosporium spp.. The distribution of epiphtes is discussed in the paper as well.
