摘要

The aim of the study was to compare the course of flowering and the occurrence of Alnus, Corylus and Betula pollen grains in the air in 1999-2001. In 2000 and 2001 birches flowered in a typical way - the flowering period was short and intense and that period had the highest concentration of pollen. Both years had no rainfall then and the temperature was high, which caused intense flowering of birches over a large area. In 1999 and 2000 most of the Alnus and Corylus pollen was recorded at the end or after their flowering period. At that time the weather was unstable (as is usual in February and March). Pollen must have been transported from elsewhere. Wind analysis showed that the main sources of Corylus pollen must have been in the south, and of Alnus in the south and west. In the southern margin of Poland the vegetative period begins later due to a colder climate.
