Plant species	Localizations
Plant species	Rural areas	Urban areas
Tilia sp.	22.74 ± 1.05^a	22.0 ± 1.71^a
Robinia pseudoacacia	10.12 ± 5.3^a	8.68 ± 3.09^a
Brassica napus var. napus	8.43 ± 3.14^a	7.44 ± 1.54^a
Eryngium sp.	nb	6.69 ± 1.72
Begonia sp.	nb	6.6 ± 0.23
Centaurea sp.	6.56 ± 2.11^a	4.89 ± 1.62^a

The pollen [mean ± SD] frequency from few species of plants in honey samples from urban and rural apiaries. Only a few dominant plant species (pollen frequency over 6%) are presented. Different letters—significant differences between pollen frequency in honey samples from two types of the apiary. Student t-test. p ≤ 0.05.
