Objective of the theses was to determine the botanical origin of bee-collected pollens using pollen analysis. The beehive, from where the pollen came from, is located in Hlavatce, which is 20 km far from České Budějovice. Bee-collected polens was obtained via pollen trap, which was put on the beehive once a week for 24 hours between 17th March to 6th June 2017. Pollens were dried, sorted according to the color shades, and the partial color samples were weighed on the analytical scales. The pollen analysis took place at a microscope magnification of 400x. The characteristics of exine (sculpture) and quantity and type of apertures were observed. The size of the grain, which was measured always in 50 pollen grains, helped to classify the plant species. Using the Shannon-Wiener Diversity Index, the bee's preferences were assessed in individual samples. The work is supplemented with photos of selected pollen grains.
