Rezumat

European beech (Fagus sylvatica L.) produces good yields once every 5-7 years, and sometimes much less frequently. In this regard, there is a need to preserve beech seeds for a long time. There are still discussions about what behavior is inherent in beech, taking into account the conditions for the best preservation of seeds – orthodox, suborthodox or mixed. For this purpose, the peculiarities of storing European beech seeds under various parameters are being studied. The aim of our work was to study the viability of seeds of origin Lviv and Zakarpattia (Ukraine) for two years using a hydrogen peroxide test (HP). Seeds of Lviv and Zakarpattia were characterized by low initial viability. The seeds were collected in the fall of 2020, air-dried to a moisture content of 9-10% and stored in sealed plastic bags at a temperature of +4±2°C. Before storage, it was established using the HP test that the viability of Lviv seeds at a moisture content of 10.73 ± 0.04% is 56.7%, while the average weight of 100 seeds reached 26.86 ± 0.94 g. Viability of Zakarpattia seeds at a moisture content of 9.56±0.02% was 50.7%, with an average weight of 100 seeds of 18.61±0.66 g. The results showed that germination viability of Lvov seeds after two years of storage was 53.0%, and seeds from Zakarpattia – 43.0%. Mathematical analysis of the data showed that both for the seeds from Lvov and for the seeds from Zakarpattia, there was no significant decrease in viability compared to the initial level – LSD=9.7 at p≤0.05. At the same time, data analysis revealed a significant difference in values after storage for 2 years between Lviv and Zakarpattia variants. Thus, when beech seeds are stored at a temperature of +4±2°C and a humidity of 9-10%, their viability fluctuates insignificantly, but the lower the quality of the initial seeds, the more significant the storage losses may be.
