Pollen Profiles and Floral Sources of Tennessee Honeys, an Influence of Appalachian Ecoregions

Tennessee and the surrounding Appalachian region offer a uniquely rich floral landscape that supports the production of many flavorful, high-quality types of honey. Plant species such as tulip poplar, black locust, basswood, sumac, and sourwood provide abundant nectar that supports strong honey yields. Pollen from plants that produce little or no nectar also contribute to a diversity of honey flavors. This study uses DNA-based pollen profiling to identify plant sources contributing to honey varieties in single frames of honey. By analyzing individual honey frames through molecular and bioinformatic techniques, the project supports how regional and local diverse plant communities contribute to honey composition.

This work demonstrates how genomic tools can be applied to classify honey by floral source, supporting future research in molecular genomics, apiculture, and biodiversity mapping. The findings also inform efforts to promote small batch honey extraction to enhance consumer awareness and valuation of locally sourced honey products.
