Summary: The pollen emission has been researched on a permanent station in Zagreb since 1973, and at 40 stations in Croatia since 1985. Synoptic and prognostic maps of the pollen spectrum have been made for the parts of continental and coastal Croatia. They are applied in the prevention of polenoses and for categorising the areas suitable for treating allergy patients. The pollen of anemo- and amphiphilous species, which cause polenoses, including that of some controversial and variable taxa was elaborated in Palinoflora Croatica. The research of pollination and pollen production were connected to morphometric, ?phenologic, floristic and vegetation research at permanent stations. Special attention was paid to the Ranunculaceae family (Helleborus, Thalictrum, Eranthis genera). Also researched was the pollen of some pharmacologically and melotologically significant species (Salvia, Tilia) from the taxonomic and morphological point of view. The categorisation and the distribution maps of the palynoalergenae? according to aggressivity degree was carried out. Pollen calendars were made for all stations, on the basis of the number of pollen grains, the pollination process and the emission time. In addition, the results of the phenological have been enhanced with the analyses of the flora and the vegetation. The synoptic and prognostic maps of the pollen emission have been designed for the region of Slavonia, parts of the continental and coastal Croatia on the basis of weekly measurements carried out during several years. By analysing individual variabilities of some species and genera the information on phyogenetic relations within higher systematic categories was achieved. The floristic and vegetation research is necessary for the development of the prognostic pollen maps. The synoptic maps are designed on the basis of the field data (measurements of the pollen production, the flora analysis, the inflorescence and pollination phenology) after several years of weekly measurements. Palynological analyses were included into the palynoteca, and the floristic and vegetation research was supported by herbarised material. Phenological research was elaborated according to the European standards (phenophasis cards), but only for some species significant for this type of research.

Keywords: Ecopalynology, plant cover, Croatia

Research goals: The basic aim of this research is to cover Croatia with a network of measurement stations for recording the pollen emission. This will include Croatia into the European network of measurements, recording and estimates of the pollen production. The results of the research are directly sent to the users, i.e. health institutions who treat and test allergy patients. This also includes the designing of the maps/atlas and the key for determination and identification of pollen entitled Palinoflora Croatica, which would cover alergenically, pharmacologically and melitologically significant genera and species. Also connected with this work are palynomorphological and palynotaxonomic research of the variable, endemic and rare genera/species of the Croatian flora. Phenomenological observation completes the knowledge on the process of pollination, which is an essential information for designing prognostic and synoptic pollen maps. These maps facilitate the determination of the areas where pollenoses are the most frequent, as well as the areas suitable for treatment of allergy patients. The design of such maps requires the analysis of the vegetation and the flora as well as following the changes of the plant cover during several years (permanent measurement stations). By analysing individual variability of genera/species the phyllogenetic relations within individual systematic units can be identified, and palynomorphology plays a significant role in that. Malformation, sterility and reduced viability of the pollen are the indicators of air and soil pollution, and are thus cited in ecological studies, along with the other parameters. It is necessary to design maps of palynoallergens, the relative pollen production maps (possible use in pharmacology, apiculture, agronomy, genetics) and an Atlas of the anemo- and amfofillous pollen of Croatia on the basis of several years of research. It is necessary to continue working on documentation of the data - completing the palynoteca, collecting exicats, extending work on phenological data, joining the European network of pollen research.
