Abstract: | Total pollen production per inflorescence and per square meter were studied in anemophilous species of the Poaceae family,
to determine the relative contribution of each species to the total load of pollen released and to identify the species with
the highest potential pollen emission. This was done by calculating the number of pollen grains per flower and per inflorescence
and by estimating the density of inflorescences in an area of one square meter. Pollen production per inflorescence varied
between 12,000 and 15 million grains, often being higher in the perennial species. Mountainous, grassland, riverside, and
littoral areas contributed similarly to the amount of pollen grain production per square meter. Species such as Gaudinia fragilis, Hordeum murinum, Lolium rigidum, and Trisetaria panicea, with high pollen records, were found in all the studied areas. Aerobiological analysis will be undertaken to determine the
main pollen season of Poaceae species. The results obtained are of great importance for respiratory health management in this
region. |
