The objective of this work was to assess the influence of the local floral composition on the quality
of apicultural pollen collected in two apiaries, in Minas Gerais State, Brazil. Five hives of Apis mellifera (L.) were
installed in each apiary. The polliniferous flora in the proximity of the apiaries was identified. The pollen loads
were collected from August to December, 2005. The melissopalinological analysis was carried out following the
standard European method. Nutritional analyses of pollen were performed related to percentages of dry, organic
and mineral matter; to raw protein; to ether extract; and to total carbohydrates. Spearman correlation was carried
out between nutritional components and pollen types. In the UFV apiary, the predominant polliniferous flora
presented ornamental species with arboreous habitus, and in the Mesmel apiary, it presented species of abandoned
cattle pasture with herbaceous habitus. The nutritional composition of the collected pollen showed no correlation
with the diversity of pollen types, however, it showed correlation with the predominance of specific pollen types.
Different floral compositions influence the quality of pollen collected by bees; and its collection by bees, in
various sources, is important to obtain a more balanced diet.
