“…In the centre of Szczecin, far from blooming plants, the highest grass pollen count was usually noted in the afternoon [11]. Dowing [30] and Takehashi et al [31] have reported that the flowers (and thus also the theca) of different species of grass open at different times of the day, e.g. the flowers of Dactylis glomerata open from 01.00-10.30, those of Lolium perenne from 08.00-16.00, and those of Poa pratensis usually at night, from 21.00-05.00, or sometimes also during the day, from 06.00-16.00.…”

Introduction. Among herbal plants, most cases of allergic reactions, like seasonal inflammation of nasal mucosa, conjunctivitis and pollen asthma, are related to the allergens from grass pollen. As the blossoming and pollination of rye is known to start the pollen season of grasses, information about the airborne rye pollen count permits alerting the people allergic to certain allergens contained in rye pollen. An important cause of allergy is also the pollen from wormwood, blossoming in late summer, as its two main allergens produce cross-reactions with many other plant allergens. Objective. The aim of the study was to evaluate the risk of allergic reactions in persons with pollinosis on the basis of the pollen calendar, analysis of concentrations of pollen grains of grass and rye, and comparison of diurnal pattern of airborne pollen grain concentrations at two sites with different degrees of urbanisation (Gudowo in the country and the city of Szczecin) in 2012-2014. Materials and methods. The concentration of pollen was measured by the volume method. Length of the pollination season was determined by the method of 98%, assuming that the beginning and the end of the pollen season are the days on which 1% and 99% of the annual sum of pollen appeared. Results. The first pollen grains to appear in the air are those produced by rye, followed by those produced by grass and wormwood. The pollen seasons of grasses and wormwood started about one week earlier in Gudowo than in Szczecin, while the pollen season of rye started at almost the same time in the country and in the city. Airborne pollen counts of grasses, rye and wormwood were much higher in the country than in the city. The differences most probably result from the different floristic composition at these two sites and reflect the local contribution of the taxa studied in the country. Conclusions. The risk of allergy caused by the pollen of the taxa analysed was much higher in Gudowo (in the country), than in Szczecin city.

“…The amounts of airborne allergens causing grass pollinosis can be roughly estimated to quantify the airborne Dac g levels, because the antibody used in the present study reacts not only to Dac g pollen antigens, but also to grass pollen antigens cross-reactive with Dac g from other plants of the Poöideae subfamily. Thus, the airborne grass pollen antigens observed before D. glomerata flowering season that bloom until late May (Takahashi et al 1993) may not have been Dac g itself, but may have been other species having cross-reactive antigens with Dac g antigen. Two early blooming species of grasses in our region are Alopecurus aequalis and Poa annua.…”
