AB  - The research was carried out in primeval forest stands of beech, fir and spruce (Piceo-Abieti-Fagetum illyricum) on brown dolomite soils (Janj) and dominantly shallow limestone soils (Lom). The diameter structure is typical for primeval forests with the participation of large trees in which physiological weakening is visible, especially in the Lom primeval forest. At the same time, the stands are characterized by the specifics of the transition from the terminal to the initial development phase, with a very pronounced lower floor of the stands where beech and fir dominate. Significant differences in the size of the diameter increment are characteristics for fir, which in the Lom primeval forest has a significantly higher diameter increment at the same diameters than in Janj. The current diameter increment of fir in Janj is 2.3 mm/year and in Lom 4.5 mm/year. The average current thickness growth of spruce in Janj is 0.2 mm higher on average than in Lom and amounts to 2.9 mm/year. The current thickness growth of beech in Lom is significantly higher (4.9 mm/year) than in Janj (2.3 mm/year). The average time of passage is the highest for fir in the Janj primeval forest and for the whole stand is 45 years, and the lowest for spruce in the Lom primeval forest 22 years. Beech trees in the lowest diameter classes have a significantly shorter time of passage than fir and spruce. Fir in the Janj forest has an average relative age of 85 years higher than in Lom. Spruce shows the largest difference in relative age between primeval forests in thinner diameter classes, and unlike fir, the difference in age decreases with increasing diameter.

AB  - The paper presents the results of research on competitive relations between sessile oak seedlings and the most important competing species of woody vegetation, as well as ground flora that grows under a shelterwood, after the preparatory-seed cut of the shelterwood cutting. The research was conducted in sessile oak (Quecus petraea /Matt./Liebl.) stand in the area of northeastern Serbia. The studied stand is located at 320 to 350 m above sea level, with a slope up to 25° and western exposure. In terms of phytosociology, the stand is defined as an association of sessile oak with hairy sedge (Carici pilosae – Quercetum petraeae B. Jov. 1989). After the preparatory-seed cut, 124 trees per ha remained in the stand, with a basal area of 11.9 m2/ha and a volume of 129.1 m3/ha. The obtained results in the paper indicate the competitive relations between sessile oak and the most important competing woody species, as well as the species of ground vegetation. The most common competing woody species are silver linden (Tilia tomentosa Moench.) and hornbeam (Carpinus betulus L.), while other species (Fraxinus excelsior L., Fraxinus ornus L., Crataegus monogyna Jacq., Acer campestre L., Cornus mas L.) are represented individually. In addition to a significant presence, competing species of woody vegetation are characterized by very intensive development, which significantly reflects on the presence and development of sessile oak seedlings. In contrast, eight-year-old sessile oak seedlings have outgrown blackberries in the studied stand, which no longer competes with them. The obtained results indicate that during the regeneration of sessile oak forests, special attention must be focused on the presence and dynamics of the development of competing vegetation, as well as that the success of the regeneration largely depends on controlling this factor.
