Abstract

Honey plants are considered a major role in the production of honey and pollen in thebeekeeping industry. In South Korea, most production of honey has largely relied on a limitedflowering plant, black locust(Robinia pseudoacacia). However, the forests of R. pseudoacaciahave been gradually declined in South Korea because the Leaf-yellowing of black locust haswidely spread to most regions since early 21st Century. Therefore, alternative honey plantsshould be studied to resolve the severe reliance on black locust in Korean beekeeping. Although610 species of honey plants are known from South Korea, the foraging activity of honey bees(Apiscerana and A. mellifera) and seasonal compositions of each region were poorly studied on them. In this study, we investigated 37 species of honey plants for estimating the foraging activity ofhoney bees for them and 41 species of honey plants for evaluating their seasonal compositionin the central area of South Korea. As a result, the following 16 trees and herbs were found ashoney plants showing a high level of honeybees activity. Buxus microphylla var. koreana, Prunusyedoensis, Rubus crataegifolius, Rhododendron schlippenbachii, Staphylea bumaldai, Robiniapseudoacacia, Rosa multiflora, Cirsium japonicum var. ussuriense, Trifolium repens, Ilexverticillata, Zizyphus jujuba var. inermis, Tilia amurensis, Koelreuteria paniculata, Fagopyrumesculentum, Perilla frutescens var. japonica, and Dendranthema zawadskii var. latilobum. Onthe seasonal composition of honey plants, Pyrus ussuriensis, Tilia amurensis, T. mandshurica,Impatiens textori, Dendranthema boreale, Elsholtzia ciliata, and Agastache rugosa wereconsidered major honey plants in Inje county, as well as Prunus spp., Robinia pseudoacacia, andCastanea crenata.
