Caracterización del aporte polínico de especies arbóreas y arbustivas en tres muestras de miel procedentes de apiarios, ubicados en el cantón La Concordia.

Abstract

This study proposes a botanical characterization of the pollen contribution in three samples of honey from the apiaries of the National Institute of Agricultural Research Santo Domingo, Quinta de Paco, Hacienda Yandun in the canton of La Concordia, province of Santo Domingo de los Tsáchilas, for the identification of the pollen profile of the three samples of honey, it was characterized according to the botanical origin. For the pollen description, the Shapiro Wilks normality test was used for Hacienda Yandun, where "ADEVA" was applied with a value (>0.05) and the "Tukey" test at 5%; for the Instituto de Investigaciones Agropecuarias Santo Domingo y Quinta de Paco, the non-parametric Kruskal Wallis test was used. The study was carried out in the laboratory using the acetolysis method for all replicates; the Motic Plus 3.0 camera was used to identify pollen grains; the neubawer camera allowed pollen counting; with the Nikon D3300 camera, the virtual palynotes library and the computer, it was possible to botanically characterize the three pollen grains in the three replicates; library and the computer were used for pollen counting. A total of 18 pollen forms distributed in 15 families and 32 species were distributed in 15 families and 32 species; where 10 families contain 14 arboreal/shrub species and reached percentages greater than or equal to 10%, which is why they are considered important species, and these are: Ageratina asclepiadea, Tabebuia chrysantha, Hevea brasiliensis, Chamaecrista calycioides, Erythrina edulis triana, Senna dariensis, Persea americana, Bougainvillea spectabilis, Triplaris cumingiana, Mussaenda erythrophylla, Citrus X limon, Citrus X sinensis, Cestrum racemosum, Nicotiana glauca. It is recommended to work with the process of acetolysis for better identification of polarity, symmetry, scope, size, apertures and ornamentation of the pollen grains, in order to know the existing species in the different areas of the country.
