The thesis investigates the response to flooding of five species types of trees occurring in floodplain forests of South Moravia. This work aimed to evauate different lengths of the seedling flooding and examined seedling vitality and mortality. The investigated tree species were summer oak (Quercus robur L.), hornbeam elm (Ulmus minor Mill.), heart linden (Tilia cordata Mill.), hornbeam (Carpinus betulus L.) and field maple (Acer campestre L.). The flooding experiment was conducted from April to July 2022 and at different time intervals (7-14 days) the seedlings were flooded up to the root collar. Control seedlings were not flooded but only watered. 140 seedlings of each species were flooded and were gradually removed from the flood. The results show that relatively low mortality was observed for the flooded trees in all intervals. It was lowest for Quercus robur and Tilia cordata, which were characterized by high vitality in addition to low mortality. Ulmus minor was characterized by moderately vital seedlings. Acer campestre and Carpinus betulus had the highest mortality and their vitality decreased significantly towards the end of the experiment. The hypothesis of Quercus robur's resistance to flooding has been confirmed, which means the seedlings of this tree can probably cope well with flooding even in the conditions of floodplain forests. Tilia cordata also coped very well with flooding. It has probably invested in trunk thickness in response to water stress, adapted to flooding and thus gained a competitive advantage over other tree species. The thesis confirmed the assumption that Quercus robur is a resilient tree species to flooding and Tilia cordata showed higher resilience than expected.
