Abstract
The study was carried out in four forest nurseries of Middle Siberia. Affected seedlings of Scots pine (Pinus sylvestris L.), Scots Siberian stone pine (Pinus sibirica Du Tour), and Siberian spruce (Picea obovata Ledeb.) were collected for molecular phytopathological examination. In total, 14 fungal taxa were identified in the needles and roots of the plants. The most dominant among them were Sydowia polyspora (Bref. Tavel) E., Didymella glomerata (Corda) Qian Chen L. Cai, Cladosporium herbarum (Pers.) Link, Lophodermium seditiosum Minter, Staley Millar, Phialocephala fortinii C. J. K. Wang H. E. Wilcox and Cadophora finlandica (C. J. K. Wang H. E. Wilcox) T. C. Harr. McNew. The richness of the fungal taxa was higher in the needles than in the roots of all the tree species studied. The obtained results could be used for implementing more effective phytosanitary measures in the studied nurseries.
