This study evaluates an experiment, in which the raise frequency of seeds, seedlings dimensions and the weight of the above-ground as well as root parts of seedlings grown from pelleted and unpelleted seeds of three conifer species: Norway spruce, Scots pine and Mountain dwarf pine are compared. The experiments was established in a random - block design with 4 to 10 repetitions on uncovered artificial substrates. Seed pelleted in a mass based on wood powder enriched by fungicides and insekticides was sown in two variants - individual sowing and glued on water - unstable sowing tape in regular distances. The results comfirm equal properties of pelleted und unpelleted seeds, concerning all triats. Pelleted seeds proved to perform better in root-collar diameter and above-ground stem length, only dry weight of roots proved to be smaller. The pelletization mass based on beech wood powder used appears to be the most appopriate of all pelletization mixtures tested until now. The results apply for growing of seedlings on plat aubstrates with 95% reliability
