This thesis is about the development and structure of mountain Norway spruce forest in location Koprová dolina, which is part of Tatras national park. Forest dynamic were monitored on 13 permanent research plots, every plot takes 1000 m2. Study was based on the analyses of the thicknes and age structure and the dendrochronologal analysis, which detects releases during growth. Based on results we confirmed that locations have character of natural forests, these locations are formed by strong and big-scale disturbances, but also by disturbances of medium and small strenght and scale. Results are similar with other papers and historical texts, which describes disturbances events in Koprová dolina.

KAŠPAR M.: Analysis of xylogenis and floemogenesis of Norway Spruce (Picea abies (L.) Karst.) during two growing seasons. The thesis deals is focused on finding and evaluating the creation of wood and phloem of Norway spruce during the vegetation period 2015 and 2016 at the reasearch area Rájec-Němčice. Six representative trees were selected on the surface and samples were taken periodically. Permanent microscopic slides were prepared and examined for the samples obtained. The activity of cambium, the different phases of differentiation of wood and bast elements and the rate of growth using Gompertz function were evaluated. The data collected for each year were compared with each other and compared with the results of other authors. Growth variations were noted within two growing seasons. Statistically significant differences were seen in the number of kambia cells, whether in dormancy or during the active period. There were statistically significant differences at the time of termination of the individual cell phases. The different values of the years also resulted from the results of the Gompertz function. Generally speaking, in 2016 the growth dynamics was more intense and the number of cells generated was higher than in the previous year.

The aim of this thesis was to determined the effect of supra-regional biocentre Rasuveň to the surrounding predominantly spruce vegetation in terms of regeneration and distance to which biocentre influence surrounding vegetation. From the results was found that the average density of beech regeneration in the surrounding vegetation was about 7,000 pieces / ha. It was monitored by using transects. And at the core of biocentre was around 19,000 pcs / ha. There was detected by using density plots. Effect of biocentre has been proved to a distance about 130 metres and density of regeneration corresponding to the minimum ha quantity for beech was appearing in a distance about 30 m from biocentre. These three following options were selected for the expansion of beech from biocentre to the surrounding spruce vegetation. Option 1 -- Carry out with min. quantity of MZD, Option 2 -- Mixed vegetation and Option 3 -- Expansion of biocentre + option 2 in the surrounding vegetation.
