The present work analyses the airborne pollen dynamic of the atmosphere of Toledo (central Spain), a World Heritage Site and an important tourist city receiving over 2 millions of visitors every year.
Hourly grass pollen concentrations were recorded over a 10-year study period at an aerobiological station of Badajoz (SW Spain). The record was carried out by means of a Burkard spore trap.
The relative amount of roots (dry weight ratio of root to shoot, or root dry weight per spikelet) or the physiological activity of roots is correlated with the cool-weather resistance in rice plants. ...
Although aerobiological data are frequently used as a fl owering sign in phenological research, airborne pollen counts are infl uenced by a number of factors affecting pollen curves.
In order to survive periods of adverse cold climatic conditions, plant requirements are satisfi ed by means of physiological adaptations to prevent cells from freezing.
Pollen concentration in the atmosphere of Vinkovci (northeastern Croatia) has been analyzed using a Hirst-type volumetric spore trap. During the year 2005, 58 pollen types were recorded with the sum o...
The aim of the study was to compare the concentration of 3 allergenic taxa pollen (ash, birch and oak) in the cities of Lublin (eastern Poland) and Szczecin (western Poland) during the years 2004 and ...
The main characteristics of the Quercus pollination season were studied in 14 different localities of the Iberian Peninsula from 1992-2004. Results show that Quercus flowering season has tended to sta...

The aim of this work was to study spatial and temporal distribution of Olea europeae airborne pollen in different Portuguese regions: Reguengos de Monsaraz (south); Bairrada (west); Braga (northwest);...
Airborne ragweed pollen concentration in the north-eastern part of Croatia was investigated in relation to some meteorological factors. Data was obtained for three consecutive years (2001, 2002 and 20...
Celtis sinensis is an introduced plant species to the southeastern region of Queensland that has had a destructive affect on indigenous plant communities and its pollen has been identified as an aller...
The aim of the study was to analyse a relationship between the meteorological conditions and the pollen counts of selected allergenic taxa (Betula spp.,Populus spp.) in the air of Szczecin city (north...
An ASTIR volumetric sampler was used for one year (May 1995–April 1996)for aerobiological survey at Beharampore town, a centrally located representative part of West Bengal,
The aim of the research was to study spatial variations in the abundance and seasonal patterns of pollen fall. The investigation was carried out at three sites of different land use during two pollen ...
