Successful artificial reforestation of European beech (Fagus sylvatica L.) directly depends on the quality of planting material. For better adaptation and survival of a new population in changing conditions, it is desirable that the planting material be genetically diverse. Therefore, the purpose of our work was to study the germination kinetics of Fagus sylvatica seeds and emergence of beech seedlings of various origins. Seeds of F.sylvatica were collected in October 2022 on the territory of the Mlyňany Arboretum of the Slovak Academy of Sciences, Zvolen, Slovak Republic – Fagus sylvatica L. (FsSR), F. sylvatica 'Rohani' (FsR), F. sylvatica 'Aurea' (FsA), F. sylvatica 'Atropurpurea' (FsAt), F. sylvatica 'Pendula' (FsP); and in the park of Schönburn Palace, Vienna, Austria – Fagus sylvatica L. (FsAu). The highest germination energy was characterized by FsSR seeds – mean time germination (MGT) for them was 62.6 days. FsAu seeds were also characterized by fairly high germination energy, MGT was 74.9 days. The lowest capacity of germination was noted for FsP seeds – 130 days. The rest tested beech seeds germinated within 103-107 days. The overall germination of seeds was distributed as follows: FsP (83.33%) > FsA (60.0%) > FsSR (58.81%) > FsAu (56.12%) > FsR (53.18%) > FsAt (37.93%). Germinated seeds were sown under solarium conditions. Emergence of seedlings was from 60 to 100%. The highest emergence of seedlings in solarium conditions was showed by the seeds of FsP (100%), FsR (85.83%), FsA (83.33%) and FsAu (81.33%). Seeds FsSR (65.56%) and FsAt (60.00%) were characterized by lower emergence of seedlings. Thus, not all seeds with high MGT indices showed the highest emergence of seedlings in solarium conditions. The seeds FsA and FsSR originated from the Slovak Republic had the highest and most stable germination rate and emergence of seedlings.
