• Resumen

  • Airborne pollen grains in the atmosphere of Gerze (North Turkey) were identified between 1st January 2017 and 31st December 2018 by means of a Burkard volumetric spore trap. The effect of meteorological parameters (mean temperature, total rainfall, relative humidity, wind speed) on the amount of pollen grains was investigated. During a period of two years, a total of 1015 pollen grains was recorded, belonging to 24 taxa. The dominant arboreal pollen taxa in the atmosphere were Cupressaceae/Taxaceae (60.2%), Pinaceae (16.9%), Alnus sp. (8.3%), Corylus sp. (2.7%), Quercus sp. (1.8%), Fraxinus sp. (1.3%), Populus sp. (1.3%) and Olea europaea (1.2%), while the dominant non-arboreal pollen taxa were Mercurialis sp. (1.5%) and Poaceae (1.2%). The pollen grains captured by the trap reflected the floristic diversity of the region. Higher temperature and wind speed were observed as influencing positively the increase of pollen amount, whereas rainfall and relative humidity had a negative effect.
