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.

西伯利亚中部森林苗圃中针叶树幼苗的真菌定植

研究在西伯利亚中部的四个森林苗圃进行。收集苏格兰松(Pinus sylvestris L.)、苏格兰西伯利亚石松(Pinus sibirica Du Tour)和西伯利亚云杉(Picea obovata Ledeb.)的患病幼苗进行分子植物病理学检查。在这些植物的针叶和根部共鉴定出14个真菌类群。其中最占优势的是多孢子雪多利亚(Sydowia polyspora，简称雪多利亚)。陈茜，蔡玲，植物枝孢菌(植物科)Link, lophoderium seditiosum Minter, Staley & Millar, Phialocephala fortini C. J. K. Wang & H. E. Wilcox和caadophora finlandica (C. J. K. Wang & H. E. Wilcox) t.c. Harr。& McNew。针叶中真菌类群的丰富度高于所有树种的根。研究结果可为苗圃实施更有效的植物检疫措施提供参考。
