Factors affecting pollen transfer effectiveness
Švanda, Petr ; Štenc, Jakub (advisor) ; Straka, Jakub (referee)
Pollen transfer efficiency, i.e., the proportion of pollen that is successfully transferred to a plant of the same species, significantly affects plant reproductive biology and creates a potentially strong selection pressure for the development of specialized strategies to increase pollen transfer efficiency. Precisely because of its importance within pollination biology, the efficiency of pollen transfer was a frequent subject of studies, in which, however, its interpretation differed depending on the method used, making it difficult to compare individual studies. Moreover, the work to date does not offer a satisfactory methodological framework for comparing the effectiveness of pollen transfer across the studied systems. The effectiveness of pollinators is primarily affected by the amount of pollen removed, the amount and quality of pollen deposited and frequency of pollinator visits. These factors are affected by additional influences, for example the behavior of the pollinator, the number of open flowers within the inflorescence or the environment variability. The result of this work is the retrieval of a methodological framework capable of determining and comparing the relevance of pollinators to pollen trasffer across plant species, which will be possible to link with theoretical models...
