Dominant Pollen Types Recovered From commercial Louisiana honeys
Tóm tắt
Microscopical pollen analyses of 54 commercial honey samples collected from the major beekeeping areas of Louisiana during 1967–68 showed six dominant pollen types (a dominant type considered as one contributing over 45% of the total grains counted per sample and denoting a unifloral honey). The dominant pollen types and the “ bee plant ” species associated with each pollen type are identified and described. The pollen types are illustrated with light photomicrographs. The pollen types are in order of importance:Trifolium repens, white clover;Rubus spp., blackberry and/or dewberry;Berchemia scandens, rattan vine;Salix spp., willow; Asteraceae, Sunflower family; and Sapiumsebiferum,Chinese tallow tree. White clover and willow were the largest unifloral honey producers in a region including the floodplain and delta of the Mississippi River, and the floodplain of the Red River (the most productive beekeeping area of Louisiana); blackberry and/or dewberry were most significant in the longleaf pine flat woods and mixed hardwoods in the uplands section on the east side of the Mississippi River; rattan vine was most important in west-central Louisiana in an area consisting originally of pine-oak-hickory uplands and longleaf pine flat woods; white clover appeared most important in the prairie region of southwest Louisiana.
