NAAB, Ofelia  and  TAMAME, María Angélica. Springtime beekeeping flora in the Monte region of La Pampa province (Argentine). Bol. Soc. Argent. Bot. [online]. 2007, vol.42, n.3-4, pp.251-259. ISSN 1851-2372.

In order to evaluate the utilized flora by Apis mellifera L. we analized inmmature honey samples and corbicular pollen loads from two demonstrative apiaries located in the Monte Phytogeographical Province of La Pampa. The samples were periodically collected during springtime and were analyzed using the conventional melissopalynological techniques. The native flora presented the major abundance and the highest number of species at an optimum flowering level in november. The most represented families in the pollen spectrum of immature honeys and corbicular loads were: Zygophyllaceae ( Larrea divaricata Cav.), Rhamnaceae ( Condalia microphylla Cav.), Solanaceae ( Lycium sp.), Asteraceae ( Senecio subulatus Don ex Hook. & Arn.) and Verbenaceae ( Glandularia sp. - Junellia sp. - Verbena sp.). The pollen analysis showed that native plants offered at the same time pollen and nectar sources, however was observed a high selection of a few floral source. The flowering offer generated unifloral honeys from L. divaricata , C. microphylla and Lycium sp. Both apiaries were diferenciated according to the diversity of pollen types and the presence of certain taxa as dominant and secondary pollen.
