AbstractThe paper presents the results of laboratory research on the effects of different bulk density and its impact on germination and growth parameters of European beech. Soil for the research was taken from the forest stand, and then poured into prepared PVC cylinders. Different bulk density was made by pressure exerted on the soil, with use of the stamp and hydraulic press. Bulk density ranged from 1,0 to 1,7 g·cm–3 with 0,1 g·cm–3 resolution. Each variant of the bulk density was repeated three times. 28 seeds of European beach were sown into a single cylinder. The cylinders were then placed in controlled conditions and after 2.5 months all seedlings parameters were measured. 211 seedlings were analysed (sown 672). It was found that there were significant correlations between the bulk density and the length of root system, length of whole seedlings, thickness in root neck and area of single leaf. With the bulk density on the level 1,0 g·cm–3, and 1,6–1,7 g·cm–3 length of root system and whole seedling, decreased and thickness in root neck, and total area of assimilation apparatus per single leaf on seedling increased.
