Journal: Studia Biologica
Year: 2013

Since the birch pollen is one of the most important recognized pollen allergen of Europe the aim of our study was to determine the abundance, timing and distribution pattern of Betula pollen in the Ukrainian cities of forest-steppe and steppe zones. The obtained results showed that the season duration is inversely proportional to the intensity of pollen load of this plant. The greatest intensity and the highest peaks were observed in the forest-steppe zone – in Poltava and Vinnitsa. Donetsk, Ode
