We evaluated the growth of Norway spruce (Picea abies [L.] Karst.) seedlings on peat and bark substrates, on their mixes and on their mixes with agroperlite. We examined the basic quantitative traits (seedling diameters and heights), the number of produced seedlings per unit area, main root lengths, number of axial shoots and dry weight of shoots and roots. Besides the study of substrate influence on the biometrical characteristics of seedlings applied standard fertilisation an experiment was established as the second variant where the effect of biostimulants was tested; they were supplied by the Jaminex Company. The experiment was established with three replications by standard technologies used in forest operations. A conclusion can be drawn that in our experiments peat was found to be the most suitable substrate for production of Norway spruce seedlings. Positive effects of biostimulants were highly significant on almost all tested substrate mixes.Keywords:
