ducted in the artificial plantations of pine (Pinus sylvestris), created by manual planting on cultivated lands. On test plots, the damage by pine fungus (Fomitopsis annosa) was of slight degree, up to 10 % of the occurrence rateof infectedtrees. Pseudomycorrhizae -root endings with amycelial outer cover and floccus penetrating into the cells of the cortex and in the central cylinder as well as typical ectomycorrhizae were observed on the pine roots. The studied ectomycorrhizae belong to the eumycetes ectomycorrhizae andare characterized by typical for them anatomic structure. Pseudomycorrhizae were not observed outside the centers of Heterobasidion annosum, on the borders of a pine damage the occurrence rate of pseudomycorrhizae was 21-25 % of seedlings' root endings, 29-32 % in parent's species and indecay areas, they are presented to a greater extent (38-54 % in seedlings and 51-57 % in parent's species).© Адамович И.Ю., Шлапакова С.Н.
