Abstract


Early spring flowering plants show large differences in the start dates of pollen emission due to high weather variability in the preceding period. In the present study, the influence of meteorological conditions on the start date of the hazel pollen season in Lublin in the years 2001-2009 was investigated. The aeropalynological study was carried out by the volumetric method using a Lanzoni VPPS 2000 sampler. The start of the hazel pollen season was determined using the 98% method. The differences in particular years of the study were over two months. Hazel pollen grains were recorded earliest in 2007, since from 13 January, and latest in 2003, from 18 March. It was found that accumulated 5-day mean temperature before the season affects the onset of the pollen season. As a result of multiple regression analysis, a statistical model was derived, which shows with great accuracy the relationship of the start of the hazel pollen season with total precipitation and the number of winter days.
