| Sumario: | <span>A total of 61 dried bee pollen samples collected in four Brazilian macro-regions within 19 municipalities were analyzed to identify the sources used by </span><em>Apis mellifera</em><span> (L.) for pollen production and to enable a more accurate product certification. Sample preparation followed the standard methodology, including washing the pollen grains with ethanol and then with water and homogenising the sediment in a water/glycerine solution for microscopic observation. Pollen counts included at least 500 pollen grains per sample. Only six samples, presenting a unique species or pollen type comprising more than 90% of the pollen sum, were considered monofloral, including </span><em>Ambrosia</em><span> </span><em>sp</em><span>., </span><em>Cecropia</em><span> </span><em>sp</em><span>.,</span><em>Eucalyptus</em><span> </span><em>sp</em><span>., Fabaceae, </span><em>Mimosa scabrella</em><span> (Benth.) spp. and </span><em>Schinus</em><span> </span><em>sp</em><span>. pollen types. The most frequent pollen types of the heterofloral pollen batches, based on a counting limit of 45%, included </span><em>Anadenanthera</em><span> </span><em>sp</em><span>., Asteraceae,</span><em>Brassica</em><span> </span><em>sp</em><span>., Caesalpiniaceae, </span><em>Cocos nucifera</em><span> (L.) sp., </span><em>Mimosa caesalpiniaefolia</em><span> (Benth.) </span><em>sp</em><span>., </span><em>Mimosa</em><span> </span><em>verrucosa</em><span>(Benth.) </span><em>sp</em><span>., and </span><em>Myrcia</em><span> </span><em>sp</em><span>. pollen types. This result may be related to the great diversity of the Brazilian flora contributing to heterofloral pollen loads and honeys.</span> |
