Pokrywa śnieżna jako czynnik wpływający na przeżywalność i kiełkowanie bukwi

The effect of the snow cover on the survival of beech seeds from the time seeds fell onto the ground until the appearance of seedlings was investigated during two seasons at the study sites in the Babiogórski National Park and in the Ojcowski National Park. The obtained results show that snow cover has influence on the shaping of a spatial pattern of seed survival, and on the appearance of germinated seedlings. However, no decisive influence of snow cover was shown on the appearance of seedlings. The drying of the germinated seeds is the main cause of their mortality.
