Sažetak

A qualitative and quantitative analysis of airborne pollen in four sites of the Friuli-Venezia Giulia region (NE Italy) is presented. The pollen was collected in 1984 with Cour traps. Most pollen types in the atmosphere of the studied sites are from woody species; a less important proportion comes from herbaceous species. The most abundant pollen types are: Cupressaceae, Ostrya, Moraceae, Pinaceae, Urticaceae, Graminaceae, Betula, Platanus, Quercus and Castanea. Trieste is quite different from the other sampling sites, both for the higher values of overall pollen counts and for the superabundant pollen shedding of Cupressaceae, Ulmaceae, Ostrya, Quercus, Moraceae, Oleaceae, Pinus, Castanea, Graminaceae, Urticaceae and other minor taxa. Udine often proves similar to Trieste, although the sites have different pollen count values. The sampling site is characterised by more intense pollen shedding by Cory- lus, Carpinus, Platanus and Fagus. Latisana is characterised by the particular abundance of Alnus and Salicaceae pollens, and for the overall low pollen counts. Tolmezzo is quite different from the other sampling sites; the main differences are in the patterns of the pollen counts for the taxa considered and in the time of pollination peaks.
