The investigation was aimed at the study of the height-growth of spruce and larch which were planted to the beech selfseeding of the same height (30 cm) and density 50 000-70 000 plants.ha-1 in the group of Fagetum pauper, forest types. The study concerned the individual mixtures of spruce and larch; the average height of their plants with naked roots was the same as that of the beech natural seeding (permanent research areas TVP 1 and TVP 4) of the plants were higher than the beech natural seeding (TVP 2 and TVP 3). The growth of the spruce of the same average height as beech natural seeding was under a significant competitive influence and that affected its shift to the middle layer at the beginning of young growth phase. In the variant where, at the moment of planting, the average spruce height was higher than that of beech, the spruce position was at the beginning of young growth phase within the upper layer. The height growth rhythm of larch was significantly more intensive than that of beech and that influenced its dominant position in the young beech stand. The analysis of competitive relations proved the higher competitive power and growth ability of larch in young beech stand in comparison with spruce.
