Effects of disinfection with fumigant Basamid and inoculation of peat substrate with vegetative alginate-bead inoculum of ectomycorrhizal fungi Gomphidius glutinosus and Tricholoma sejunctum on development of one- and two-year-old bareroot Norway spruce seedlings were estimated. Two substrate treatments (disinfected and nondisinfected) and four inoculation treatments (2 fungi, beads lack of mycelium, no application) set up 8 combinations of main effects arranged in a randomized complete block design. Growth variables were assessed after the first and second, ectomycorrhiza formation only after the first growing season. Data were analyzed by two-way analysis of variance. The disinfection suppressed weed growth but affected unfavorably survival, needle color and seedling growth. Fungal inoculation had a mild stimulate effect on growth of one-year-old seedlings; differences between inoculated and uninoculated seedlings disappeared in two-year-old seedlings. Inoculation was not successful to form specific ectomycorrhizal morphotypes or increase total ectomycorrhizal rate of inoculated seedlings; the applied fungi were not sufficiently competitive to naturally occurred ectomycorrhizal fungi. Significant effect of interaction of disinfection and inoculation on occurrence of some ectomycorrhizal morphotypes was found. The results suggest the possible unfavorable effects of substrate disinfection on seedling development and difficulties of artificial mycorrhization of seedlings in operational conditions.
