          Abstract

          Se realizó el estudio de 32 muestras de miel procedentes de dos cosechas correspondientes a la temporada apícola 2012 - 2013 en la comunidad de Cuyo Grande, Valle Sagrado de los Incas, Cusco; con el propósito de determinar su espectro polínico mediante análisis melisopalinológico, y a partir de éste identificar las fuentes de polen y néctar usadas por Apis mellifera L. Para ello se realizaron preparaciones microscópicas acetolizadas, los granos de polen obtenidos fueron reconocidos por comparación con una palinoteca de referencia. Se determinaron 53 morfotipos polínicos en la cosecha de octubre - noviembre y 103 en la de marzo - abril. Las familias Asteraceae, Fabaceae y Lamiaceae aportaron mayor número de morfotipos, con Escallonia sp. y Eucalyptus sp., como las principales fuentes de polen y néctar, las mismas que constituyeron mieles monoflorales, coincidiendo con el momento de máxima floración de dichos taxones y acorde a la intensa actividad de las abejas melíferas observada en ellas. Además, se propone a Ambrosia arborescens Miller, Berberis sp., Cantua sp., Colletia spinosissima J.F. Gmel., Nicotiana tomentosa Ruiz & Pav., y Ranunculus sp., en combinación con Escallonia sp. y Eucalyptus sp., como marcadores del origen geográfico de la miel estudiada. La composición del polen secundario y de menor importancia, fue similar para ambas cosechas, se destacan Brassicaceae, Baccharis sp. y Senecio sp., debido a la extensa distribución de estos taxones y a sus amplios y abundantes periodos de floración.

          Translated abstract

          In order to determine the pollen spectrum of honey produced at Cuyo Grande, Sacred Valley of the Incas, Cusco, through pollen analysis and to identify sources of pollen and nectar used by Apis mellifera L., 32 honey samples were studied from two harvests corresponding to the beekeeping season 2012 - 2013. In all cases acetolized microscopic preparations were carried out, pollen types obtained were identified by comparison with a reference collection. 53 pollen types were identified from the harvest of October - November and 103 from the harvest of March - April. Asteraceae, Fabaceae and Lamiaceae were the families which contributed the largest number of pollen types, Escallonia sp. and Eucalyptus sp., were main sources of pollen and nectar, the same that constituted monofloral honeys, due to their maximum flowering moments and the intense activity of honeybees observed in them. Pollen types such as Ambrosia arborescens Miller, Berberis sp., Cantua sp., Colletia spinosissima J.F. Gmel., Nicotiana tomentosa Ruiz & Pav., and Ranunculus sp., in combination with Escallonia sp. and Eucalyptus sp., are suggested as geographical markers. The composition of secondary and minor pollen was similar for both harvests, with Brassicaceae, Baccharis sp and Senecio sp as the most important taxa, due to their wide distribution and their broad and abundant flowering periods.
