Palynological characterization of honeys from the plain of the Senguerr river (Chubut-Argentina)

Abstract

In order to know the plants used by honeybees in the Senguerr river plains, a palynological analysis of 19 samples of honey was made. Most samples had less than 2000 grains/g. Fifty-seven types of pollen were identified. Main sources of nectar belong to the following families: Fabaceae, Rosaceae, Brassicaceae and Asteraceae. Honeys were classified as monofloral Melilotus sp. (8 samples), monofloral Rosaceae (wild and cultivated, 2 samples) or of mixed floral origin (9 samples). The analized honeys may
be distinguished by a pollen association of Trifolieae, Brassicaceae, Rosaceae, Acaena sp., Glycyrrhiza astragalina Gillies ex Hook. & Arn. and Cyperaceae.
