Occurrence of Allergenic Hazel Pollen
Original language description
Recreation is limited by the occurrence of allergenic pollen. The beginning of the growing season, and thus recreation, is determined by an increase in air temperature. However, the flowering of common hazel (Corylus avellana), whose pollen is allergenic, also begins. The average flowering time of the hazel in Lednice is 50 days and it blooms for about 26 days. In the last 10 years, there has been a later onset and a shorter flowering period. For the city of Ostrava, data from the two nearest phenological stations, Mladecko and Valašské Meziříčí, are processed for comparison. Both stations have more than twenty years of data. The average flowering time at the Mladecko station is 47 days and it blooms for an average of 45 days. In the last ten years, each year, a longer flowering period with an earlier onset has alternated with a shorter flowering period and a later onset of the beginning of flowering. The Valašské Meziříčí station shows a later onset and a shorter flowering period. The onset of the flowering period begins on average 66 days a year and lasts about 21 days. For people suffering from pollen allergy, the flowering period is less favorable for being in nature.
