Sažetak
In this paper the results of the experiment testing the influence of various growing substrates (Lithuanian peat, Humofin substrate, Stender A400 substrate) and slow-release fertilizers (Osmocote Exact Standard 5-6 M and 12-14 M)on the growth and physiological parameters of Common beech (Fagus sylvaticaL.) seedlings in a nursery and in the field conditions follo wing planting. The trial was set up in the nursery of the Forest Research Insti tute Jastrebarsko, as a randomized block with eight treatments and four repetitions. Concentrations of nitrogen, phosphorous, potassium, calcium, magnesium and chlorophyll were determined in the leaves of seedlings. See dling heights, root collar diameters, and biomass of leaves, stems and roots were measured at the end of the first vegetation season. Seedlings were then moved to the nearby beech forest area where rejuvenation by planting of beech seedlings following the final cut was planned. After two years the heights and root collar diameters of planted seedlings were measured. Fertili zation with Osmocote Exact had a positive influence on the concentrations of mineral nutrients and pigments in leaves, and growth of seedlings. Out of three tested substrates, Lithuanian peat was the most appropriate for growing beech seedlings. In control treatment, Stender substrate was the best since it comes with some mineral fertilizer already added. The differences in growth dynamics among seedlings treated with different fertilizers can be of great im portance regarding the influence of weeds after planting.
