Resumen:
melisopalynological study of 49 honeys samples from the northwest of Córdoba province was performed. Prosopis spp., Larrea divaricata, Schinopsis spp., Condalia microphylla, Sarcomphalus mistol, Cercidium praecox, Geoffroea decorticans, Capparis atamisquea, Aloysia gratissima, Mimosa spp. and Schinus spp. were the most frequent and important pollen types, all of them correspond to native species. Four different groups were validated by the discriminant analysis, Traslasierra, Perisalina, Chaco Arido and Chaco Serrano, some species were proposed to differentiate between them: Schinus areira, Maytenus vitis-idaea, Cantinoa mutabilis and Schinopsis spp. respectively. Pollen types with the highest species importance index and frequencies are proposed as markers to be used in designation of origin.
