Comportamiento aerobiológico del polen de algunos taxones herbáceos riparios en Salamanca (centro-oeste de la Península Ibérica)

Resumo

Atmospheric pollen levels of Cyperaceae, Juncaceae and Typhaceae were studied in 2000-2007 period by means of a Hirst Volumetric Spore Trap in the city of Salamanca (MW Spain). The intra-diurnal pattern and the influence of selected meteorological parameters in Cyperaceae airborne pollen concentrations were also analysed. Seasonal distribution was focused between May and August for Cyperaceae and Juncaceae, between late May and mid-October for Typhaceae. In addition, their airborne pollen levels did not overcome 10 grains/m3. In the case of Cyperaceae, intra-diurnal distribution showed greater levels between 11 and 20 hours, and temperature, insolation and NE-N winds had a positive influence in atmospheric concentrations, whereas rainfall and relative humidity displayed negative correlation coefficients with Cyperaceae pollen concentrations.
