Caracterización del aporte polinico de especies arbóreas y arbustivas en tres muestras de miel procedentes de tres apiarios, ubicados en el cantón Orellana.

Abstract

The present investigation consisted of the characterization effect of the pollen contribution of tree and shrub species in three samples of honey from three apiaries, located in Orellana city. For this purpose, samples one, two, and three were collected. In the laboratory phase, the melisopalynological analysis method was applied to the honey samples. The pollen sediment was placed in the Neubauer chamber with the help of a micropipette and the Motic chamber coupled to the microscope was used. Then, the size was shaped with the help of a virtual palinoteca. For the count, a zigzag sweep was made with the 40X lens. The kinds of honey were categorized according to the frequency class of Louveaux et al., 1978. It was indicated that they are >45% monofloral honey and less than this percentage is multifloral honey. In the results obtained, there were 20 families and 31 species, and showed that the dominant taxa in this research were the Fabaceae family with 7 species. Sample one was classified as multi-floral honey since it is made up of some species such as Mimosa polydactyla 27%, Macroptilium longepedunculatum with 13%. The honey of sample two presented a multi-floral botanical origin by the species Cecropia engleriana 34%, Parthenium hysterophorus 23.33%. Finally, the honey of sample three was classified as monofloral honey due to its high pollen content of the species Mimosa polydactyla, 64 .33%. It is recommended to carry out the pollen characterization study of honey in Orellana city in times of lower rainfall, which will allow better evidence of the floral preference that bees have towards honey plants in a different flowering period.
