DYNAMICS OF DEVELOPMENT OF FIR AND DOUGLAS-FIR CULTURES ON HUSARIK EXPERIMENTAL SITE

The paper presents the next knowledge of artificial regeneration by both sowing (conventional and microseeding in the growing cells) and planting (using bare-root and containerized seedlings) of the fir and Douglas-fir during 4 growing seasons in Husarik experimental site. For both tree species, significantly better was germination of seeds in the growing cells compared with conventional sowing. Parameters of both the Douglas fir plantings from sowing and planting are similar/comparable (50-67 cm). Bare-root planting of fir preserved its tendency to slow height growth (3-17 cm per year), while individuals from sowing (both conventional and micro-seedings) and containerized plantings grown faster with roughly comparable average height (16-21 cm respectively).
