Análisis del aporte polínico de especies arbóreas y arbustivas en tres muestras de miel procedente de apiarios, ubicados en el cantón Latacunga provincia de Cotopaxi.

Abstract

The aim of this research was to analyze the pollen contribution of arboreal and shrub species in three samples of honey from apiaries in Latacunga canton, province of Cotopaxi, the pollen contribution analysis was obtained using the Shapiro-Wilks methodology and the Kruskal Wallis non-parametric data analysis was used. For the collection of the honey samples from the three apiaries, the honeys were extracted with the help of an spatula and centrifuged. Each sample was hermetically stored sealed 250 ml glass bottles duly labeled, reaching room temperature until analysis. Acetolized microscopic preparations were made, the pollen grams gotten were recognized by means of a microscope to determine their size and shape, and then compared with a palinotheca. The melisopanological analysis showed that the dominant families in this research were Myrtaceae and Fabaceae with two and four species, respectively. The honeys from Latacunga canton, presented 18 pollen types which were categorized according to the frequency class according with Loveaux et al., 1978. Sample one presented a percentage of 51% of the Myrtaceae family with the species Eucalyptus globulus Labill, which indicates that it is a monofloral honey. Sample two showed a percentage of 53% of the Myrtaceae family with the Eucalyptus globulus Labill family, which showed us that it is a monofloral honey. The third sample showed a percentage of 50% of the Fabaceae family with the Baptisia australis (L.) R. Br. species, which showed us that it is a monofloral honey. Due to the preliminary results, it is intended to awaken the interest of beekeepers to continue with similar studies at local and regional level with the purpose of giving an added value to the product, with the recommendation to implement apiaries in areas with the Eucalyptus globulus Labill species.
