Pollen characterization of multifloral honeys from La Palma (Canary Islands)

Abstract
The pollen content of twenty-five honey samples from twelve different apiaries on La Palma (Canary Islands) was subjected to qualitative and quantitative melissopalynological analysis. The quantitative analysis showed that 4% of the honey belonged to Maurizio Class II, 88% to Class III, 4% to Class IV and 4% to Class V. In the qualitative analysis, 60 pollen types were identified from 40 different families. The number of pollen types per honey sample ranges between 16 and 37 (mean of 25.8). Foeniculum vulgare-type and Rumex sp. pollen were present in all the samples. Castanea sativa and Echium plantagineum pollen were found in 96% of them and the combination Aspalathium bituminosum, Bidens pilosa-type and Erica arborea in 92%.
