The study aimed to evaluate the effect of different regeneration methods on the natural regeneration of sessile oak (Quercus petraea (Matt.) Liebl.) under the conditions of the Training Forest Enterprise Masaryk Forest Křtiny. The research was conducted in seven forest stands within the 2nd to 4th forest vegetation zones. Following the seed year of 2022, regeneration interventions were implemented in the form of clear-cutting and shelterwood cutting. On research plots (minimum size 0.2 ha), a total of 331 seedling samples were collected and measured for above-ground height, length of the main taproot, and diameter at the root collar. The results showed that seedlings growing in clear-cut areas achieved significantly higher values in all measured parameters compared to those from shelterwood-cut areas. Increased light availability on clear-cuts supports assimilate production and accelerates seedling growth, whereas limited light conditions under shelter can hinder early development and increase vulnerability to competing vegetation. The findings highlight the importance of considering light and site conditions in silvicultural planning to ensure the establishment of stable and vigorous oak stands under changing climate conditions.
