  Rezumat:  The quantitative monitoring of the airborne pollen offers important information regarding the flowering phenophase duration, the possibility of creating pollenic calendars for a certain geographic region and gives hints on the periods when pneumallergens may reach dangerous quantities. This study was planned in order to determine annual dissemination of Plantago pollen grains in the atmosphere of Timişoara in 2000-2004. Pollen belonging to Plantago was sampled during a 5-year atmospheric pollen-monitoring programme in Timişoara, România, using a VPPS 2000 Lanzoni trap. Annual variations in the concentration of pollen in the atmosphere were analysed by the volumetric method. Plantago airpollen constitutes between 0.9% and 3.39% of the annual total of pollen grains. During the studied period, inter-annual variations, concerning the total annual pollen counts and the beginning, peak and ending dates of the Atmospheric Pollen Season (APS), were reported. The daily quantities of pollen are expressed as numbers of pollen grains per cubic meter of air per day (PG/m3).
