| Summary: | Airborne pollen concentration in the Mar del Plata atmosphere was analyzed during two consecutive years. Also plant sources and flowering development was studied. Quercus was the selected taxon. Pollen amount depends on plant number and spatial distribution. Pollen patterns agree with floral phenology. Q. robur productivity was higher in 1993 due to better conditions before flowering time. On the contrary Q. ilex annual sum was higher in 1994; a cyclic reproductive rhythm is postulated. Meteorological conditions during dispersion are not enough to explain interannual variability.
KEY WORDS. Airborne pollen. Flowering phenology. Productivity. Dispersion. Urban vegetation.
