“…This rhythm is characterized by twoyear fluctuation and does not depend or depends weakly on weather parameters. This phenomenon is also confirmed by other authors, e.g., Jato et al [24], Latałowa et al [11], and Jäger et al [20]. Our results did not reveal such clear relationships.…”

Fluctuation of birch (Betula L.) pollen seasons in Poland

et al. 2015

Birch pollen grains are one of the most important groups of atmospheric biological particles that induce allergic processes. The fluctuation pattern of birch pollen seasons in selected cities of Poland is presented. Measurements were performed by the volumetric method (Burkard and Lanzoni 2000 pollen samplers). The distributions of the data were not normal (Shapiro–Wilk test) and statistical error risk was estimated at a significance level of <em>α</em> = 0.05. Pollen season was defined as the period in which 95% of the annual total catch occurred. The linear trend for the selected features of the pollen season, skewness, kurtosis and coefficient of variation (<em>V</em>%) were also analyzed. During the 12–14 years of study, the beginnings of birch pollen seasons were observed 7–14 days earlier, the ends were noted 5–10 days earlier, and the days with maximum values occurred 7–14 days earlier compared to the long-term data. The left-skewed distribution of the pollen season starts in most sampling sites confirms the short-lasting occurrence of pollen in the air. The threat of birch pollen allergens was high during the pollen seasons. If vegetation is highly diverse, flowering and pollen release are extended in time, spread over different weeks and occur at different times of the day. Flowering time and pollen release are affected by insolation, convection currents, wind, and turbulence. Therefore, pollen seasons are characterized by great inter-annual variability.

“…These phenological phases include the start of flowering and rarely the full term or end of flowering. Flowering dates of allergy-inducing species can be related to pollen counts by sampling stations [19, 20, 21]and are utilised within pollen forecasting systems.…”

The transfer of pollen from floral anther to recipient stigma is the critical reproductive event among higher plants – this is the botanical view of pollen. Proteins and glycoproteins from pollen can function as allergens, environmental molecules interacting with the human immune system to elicit an allergic response in susceptible individuals – this is how allergists and immunologists see pollen grains. Between 10 and 25% of the population now have symptoms of hay fever or allergic asthma and the incidence has more than doubled in the past three decades while the reason(s) for this increment are only hypothetical, but there is a multitude of them. Despite our natural focus on this impact of pollen on human health, pollen have to be considered in a larger context. First of all, to evaluate the bioavailability of allergens from pollen, we have to understand their function and their influence factors. Furthermore, pollen grains are not only releasing proteins eliciting specific immune responses, but they also liberate bioactive lipid mediators and this much more rapidly. And last but not least, recent observations indicate, that pollen do not only induce allergy and thus have a much broader impact on human health. This review is an attempt to favour this holistic view of pollen and their impact on human health.

“…The determination of the pollen season phases is an important goal in aerobiological, agricultural and ecological studies Benninghoff, 1991;Latorre, 1999;Moriondo et al, 2001;Jato et al, 2002aJato et al, , b, 2006Jato et al, , 2007Ribeiro et al, 2007). Thus, several authors have proposed methods to define the pollen season duration or phases such as the start, peak and end date (Nilsson and Persson, 1981;Lejoly-Gabriel and Leuschner, 1983;Andersen, 1991;Spieksma et al, 1995;Jager et al, 1996;Feher and Jarai-Komlodi, 1997;Giorato et al, 2000;Sanchez-Mesa et al, 2003).…”

-In the last few years, many studies have used airborne pollen to record the flowering season of plants. However, the airborne pollen found in traps does not always originate from or reflect the flowering period of the taxa from the studied surroundings. This study compared aerobiological, melissopalynological and flowering phenological data obtained from olive trees. The results of the study suggest that pollen loads collected by honeybees can be used as an alternative method to airborne pollen to record the flowering phenological phases and to provide accurate results.aerobiology / melissopalynology / phenology / pollen season / pollen loads / Apis mellifera
