Determination of botanical and geographical origin of Pollen samples of honeys collected by Apis mellifera Linnaeus in Cauca Department, Colombia

Abstract

Introduction: For the commercialization and marketing of honeys it is important to determine the botanical and geographical origin through pollen studies of honeys collected by Apis mellifera (A. mellifera). Objective: to carry out a pollen analysis on honey samples from the department of Cauca, Colombia collected by A. mellifera. Materials and methods The honeys samples were taken in 11 apiaries during 12 months (2014-2015) to the municipalities of Timbio, Totoró and Piendamó. Moreover, specimens of herbarium were taken from melliferous plants at 2Km from the apiaries. Results: There were identified 86 pollen types immersed in honeys, of which in guava (Psidium guajava - Mirtaceae) with 64% was the most frequent type for the municipality of Totoró. Limpiadientes (Gouania polygama - Ramnaceae) with 18.2% and 46% in Piendamó and Timbio respectively. The rest of the pollen types were found in smaller proportions. Conclusion. The pollen analyses indicated that the honeys collected during the investigation are classified as polyfloral by the high variety of plants cultivated and wild that conserve and cultivate the beekeepers of Cauca.
