This dissertation thesis deals with ability of secondary crown formation after opening a canopy and secondary crown utilization in landscape architecture. The ability of different taxa of trees to form a secondary crown after opening a canopy is genetically conditioned and influenced by the specific terms of habitat, tree age, physiological state of the individual and the specific characteristics of the individual. As a model plant for this dissertation thesis was chosen a representative of the Quercus L. genus which is very frequently used in landscape architecture. Specifically, Quercus cerris L. taxon was chosen which is grown in forest stands of Lednice-Valtice Cultural Landscape as a monoculture. Field research was conducted in forest stand edges of Forest management unit Židlochovice, namely in forest district Valtice. In this forest district were found suitable sites that meet the condition of chosen evaluation methodology, allowing comparable statistical evaluation. Enough suitable forest stand edges were found that were selected for the experiment. To the topic of secondary crown formation after opening a canopy and practical utilization of secondary crown is paid only little attention in specialized publications and in both basic and applied research. This thesis brings knowledge that can significantly contribute to the development and importance of field Landscape architecture in contemporary society. The thesis brings a lot of new information and relationships that occur during tree crown regeneration when opening a canopy. These findings can be used for example during the regeneration of untended objects of garden art monuments and other objects of landscape architecture. The results may also help in the conversion of forest stands to different objects of landscape architecture both in urban and rural settlements. The results allow modeling the development of woody plant vegetation elements in these objects. It is clear that arbitrary regenerative ability of secondary crown formation and thus the replacement of the primary crown is not sufficient but it is always necessary to respond on this ability of regeneration by various means of tree care measures so that the whole intention reaches the optimal result. The results indicate that primary or secondary woody plant vegetation element opening a canopy is able to regenerate in order to increase its landscaping value or to increase its dendrological potential of the compound vegetation element. Knowledge can also be used for regeneration of trees on the newly created forest stand edges, historical parks or other compound woody plant vegetation elements.
