IVANČO Miroslav, 2021. Growth properties of wild service tree (Sorbus torminalis (L.) Crantz) in stands with winter oak (Quercus petraea (Matt.) Liebl.) - Diploma thesis. Zvolen: Technical University of Zvolen, Faculty of Forestry. 2021. 55s. In this final work, we focus on the study of growth properties of unknown, but interesting, tree species of Wild service tree in winter oak growth. This woody plant that has the suitable preconditions for it to become an important stabilizer of oak ecosystems. The goal was to describe the structure of stands with natural occurrence of this tree, analysis of its properties in selected stands and based on the results to evaluate the impact of individual types of structures on its growth. During the analysis, we determined the basic structural characteristics, we calculated structural indices, we found out the relationship between individual quantities and we evaluated the quality of the individuals themselves. We found that two of the examined stands are, in terms of abundance, mainly formed by hornbeam, nevertheless has the oak on volume almost the same proportion like hornbeam. Growth 608 consists mainly of oak, which has on volume much larger share than in the number of trees.The number of individuals in growth 83 and 84 is opposite growth 608 much lower, so the stands are sparse, which gave the wild service tree more space for proper grow and development. This is reflected in the thicknesses and heights, which in this growths wild service tree has achieved and these are really admirable. Therefore, we suggest when growing this tree apply positive choices, to create more growth space.
