Pollen analysis of honeys from Yığılca region (Düzce), Turkey

Abstract

The aim of this study is to determine the plant species preferred by Apis mellifera L., which is a valuable genotype in terms of vitality and high honey production. For this purpose, seven honey samples from Yığılca region in Düzce (Turkey) were examined for pollen analysis. As a result of the pollen analysis on these samples, it was determined that Yığılca local honeybee use pollen grains of 43 different taxa from 26 families. Six samples of honey were unifloral (> 45% pollen of one taxon in sample) with four being unifloral for Rhododendron ponticum L. and two for Castanea sativa Mill. One sample of honey was classified as multifloral with the percentages of secondary and rare pollen groups. The honeys had contained 14 to 30 different types of pollen. The average number of pollen types per honey was 21. The dominant groups of pollen grains were determined as Rhododendron ponticum L. in 4 samples and Castanea sativa Mill. in 2 samples. Secondary pollen components were from 3 taxa: Fagus orientalis Lipsky, Rhododendron ponticum L. and Quercus L. sp. Four pollen types occurred as 'minor' types and pollen grains of 37 taxa were in rare quantities. Asteraceae, Fabaceae, Fagaceae, Lamiaceae and Rosaceae were the most represented families in honey samples.

Investigation of Some Quality Criteria in Chestnut Honey of Düzce Province

“…In another study examining the honey from the Düzce Yığılca region, pollen detection of 43 different taxa from 26 families was conducted. In two of the seven samples, C. sativa pollen was recorded dominantly with percentages of 91.5% and 92.5% [20]. Another palynological study conducted in the Yığılca region examined chestnut honey propolis, and identified C. sativa pollen at a rate of 80.5% [26].…”
