SAYAS RIVERA, Rosario  and  HUAMAN MESIA, Luis. Determination of pollen flora of Oxapampa valley (Pasco-Peru) based on palynological studies. Ecol. apl. [online]. 2009, vol.8, n.1-2, pp.53-59. ISSN 1726-2216.

In order to evaluate the potential of pollen flora of Oxapampa Valley (Pasco-Perú), 19 samples of bee pollen were evaluated, collected from 7 apiaries on the districts of Huancabamba, Chontabamba and Oxapampa. We conducted a floristic inventory for a herbarium and a reference pollen library. Corbicula pollen samples were obtained through hunting-pollen traps. Corbicula pollen samples were separated into groups according to the color of the pollen accumulation and estimates of specific pollen frequency were performed by these groups of color. The reference samples of flora and Corbicula pollen were acetolized and analyzed by microscopy to identify the morphological types of taxa present, correlating the color of the Corbicula pollen accumulation with species identified in samples. Palynological analysis performed on samples of bee pollen resulted in the presence of 47 taxa distributed in 27 botanical families, Dictyocaryum lamarckianum, Juglans neotropica and Cyrtocymura scorpioides were the species that reached the highest relative frequencies across Oxapampa Valley. The most frequent colors of the Corbicula pollen were brown, yellow and orange. The Corbicula pollen of the species Vernonanthura patens, Cecropia sp, Cyrtocymura scorpioides and Baccharis latifolia showed a greater variety of shades of colors.
