  • The purpose of this study is concerned with identification of floral type of commercially available honeys and pollen loads. Ikuse's technique was applied to identify the pollen species of honey and pollen loads. Among six kinds of commercially available honeys in Taegu, Korea i.e. Robinia Honey, Brassica Honey, Castanea Honey, Rhododendron Honey, Lespedeza Honey and Multipant Honey, all honeys contained pollens, which were coincident with their trade names given by the apirists, except Lespedeza Honey. The trade name of imported honeys were not given by the plant, from which pollen material and nectar were collected. Among four kinds of these products, pollen was not identified in Clover Honey. A spectrum of honey products added by pollen loads was, of course, wider than simple honey products. The pollen load showed spectrum of pollens including not only those which are specialized for wind pollination, eq. Pinus species and Gramineae, but also contained for insect pollination, eq. rose and leguminous plants.

  • Background: Pollen is an important source of protein and lipids for many animals including honey bees. In order to understand the foraging behaviour of honey bee colonies and preference among the available floral resources, pollen collections from three experimental healthy colonies of honey bees were analysed in the month of June. Results: The amount of pollen collections were related to the colony's need which was indicated by the number of larval and adult bees present in the hive. Interesting was the sequence of pollen collection from different floral sources. All honey bee colonies collected pollens from Trifolium repens first, then Erigeron annus and the third choice was Coreopsis drummondii and Oenothera biennis flowers. Total protein content of Trifolium pollen was the highest (20.0 g/100 g DM), and the others were in the range of 8.9-11.4 g/100 g DM. Conclusion: The results indicated that the first criteria for honey bee foraging preference of pollens would be the nutritional contents of protein and the resource availability of the lesser nutritious floral sources. This information can help pollinator protection programmes of habitat manipulation using flowering plants for nectar and pollen sources.

  • Mad-honey poisoning is mainly brought about by the honey imported from Napal, Turkey, Brazil and other parts of Europe. This mad honey is extracted from Ericaceae plants of Rhododendron species and contains grayanotoxins that causes poisoning. These toxic compounds exert a specific stimulatory action on membrane permeability to Na+ions in various excitable tissues and cause depolarization of cell membranes. The toxic effects of grayanotoxins contained honey are mainly cardiovascular disturbances with bradycardia, cardiac arrhythmia, hypotension. There are Other symptoms like nausea, vomiting, salivation, dizziness, weakness and loss of consciousness. The precise amount for a toxic dose is not known. In general the severity of the honey poisoning depends on the amount ingested. Two cases of mad-honey poisoning are described here. Both patients showed bradycardia and arterial hypotension after ingestion of honey which was brought from Nepal. They were recovered fully within 24 hours after administration of fluids and atropine sulphate.

  • Background: Though the biomass of floral vegetation in understory plant communities in a forested ecosystem only accounts for less than 1% of the total biomass of a forest, they contain most of the floral resources of a forest. The diversity of understory honey plants determines visitation rate of pollinators such as honey bee (Apis mellifera) as they provide rich food resources. Since the flower visitation and foraging activity of pollinators lead to the provision of pollination service, it also means the enhancement of plant-pollinator relationship. Therefore, an appropriate management scheme for understory vegetation is essential in order to conserve pollinator population that is decreasing due to habitat destruction and disease infection. This research examined the diversity of understory honey plant and studied how it is related to environmental variables such as (1) canopy density, (2) horizontal heterogeneity of canopy surface height, (3) slope gradient, and (4) distance from roads. Vegetation survey data of 39 plots of mixed forests in Chuncheon, Korea, were used, and possible management practices for understory vegetation were suggested. Results: This study found that 113 species among 141 species of honey plant of the forests were classified as understory vegetation. Also, the understory honey plant diversity is significantly positively correlated with distance from the nearest road and horizontal heterogeneity of canopy surface height and negatively correlated with canopy density. Conclusions: The diversity of understory honey plant vegetation is correlated to vegetation structure and human impact. In order to enhance the diversity of understory honey plant, management of density and height of canopy is necessary. This study suggests that improved diversity of canopy cover through thinning of overstory vegetation can increase the diversity of understory honey plant species.

  • 바크는 심비디움 분화의 배지로서 국내에서 가장 많이 이용되는 배지지만, 분화 수출 시 제거 과정 중에서 쉽게 떨어지지 않아 뿌리가 손상되어 상품성이 낮아지게 된다. 본 연구에서는 식물체로부터 쉽게 제거되며 바크를 대체할 수 있는 배지를 선발하고 이때 식물의 생장에 필요한 시비량을 알아보고자 하였다. 심비디움 'Honey Hot'와 'Desert Look'의 묘를 바크, 코코칩, 그리고 피트모스 배지에 식재하였고, 완효성 비료 2, 4, 6g을 처리하였다. 심비디움 묘들은 일반적으로 2년 동안 재배하고 3년째 되는 해에 개화시켜 상품으로 출하하게 되므로, 1년차와 2년차에 식물의 생장 특성들을 조사하였으며, 배지의 특성과 잎의 무기이온 함량을 최종적으로 조사하였다. 1년차에는, 'Desert Look'의 생육이 피트모스 처리구에서 바크보다 더 향상되었다. 'Honey Hot'의 생육 측정값들은 바크 처리구에서 가장 높은 값을 보였다. 2년차에는, 두 품종 모두 피트모스 처리구에서 생육이 향상되었다. 코코칩 처리구들은 바크와 피트모스에 비해 생육이 안 좋았다. 모든 배지 처리구에서 시비량에 따른 유의성은 보이지 않았다. 피트모스는 바크에 비해 CEC가 높아 더 많은 양분들을 보유하므로 식물의 생육을 향상시켰다. 특히, 엽내의 높은 K과 Ca 함량은 식물 생육에 좋은 것으로 판단되었다. 결과적으로, 심비디움 묘 생산에서 피트모스가 바크를 대체할 수 있는 것으로 판단되었으며, 이때 배지가 너무 과습하지 않도록 주의가 요구된다.

  • This study was performed to evaluate the possible production of a functional beverage derived from abalone and with several plants (AP). Five types of AP composites were prepared having different medicinal plant compositions (AP- I : abalone, garlic, jujube, Chinese matrimony fruit, dried orange peel, licorice root, zinger, honey; AP- II: abalone, garlic, black bean, Chinese matrimony fruit, cornus fruit, licorice root, zinger, honey; AP-III : abalone, jujube, arrow root, milk vetch, dried orange peel, licorice root, zinger, honey; AP-N: abalone, black bean, arrow root, milk vetch, cornus fruit, liquorice root, zinger, honey; AP-V : abalone, garlic, Chinese matrimony fruit, milk vetch, licorice root, zinger, honey). In vitro analysis were performed to examine the antioxidant contents and alcohol dehydrogenase activities of the composites. AP- II had the highest total phenol contents ($28.55{\pm}1.56\;mg/l00\;g$), and AP- V the highest level of flavonoids ($47.61{\pm}1.58\;mg/l00\;g$). At $78.89{\pm}0.16%$, AP- V displayed the strongest electron donating ability followed by AP-II($57.99{\pm}0.21%$) and API ($37.66{\pm}0.20%$). Reducing power was also significantly higher in AP- V. The Hydroxyl radical scavenging and SOD-like activities of all composites were less than 15% and 20%, respectively. At 12.5% alcohol concentration, ADH activity ranged from $114.47{\pm}2.18{\sim}121.39{\pm}4.36%$ and ALDH activity ranged from $100.04{\pm}2.90{\sim}129.54{\pm}4.80%$; AP- I , AP- II, and AP- Vin 12.5% of alcoholic concentration. The composites of AP- I , AP- II, and AP- V, all containing garlic and Chinese matrimony fruit, were significantly stronger than AP-III and AP-N. Finally, also at 12.5% alcoholic concentration, the ALDH activity of AP- V was higher than its ADH activity.

  • Background: Pollinators help plants to reproduce and support economically valuable food for humans and entire ecosystems. However, declines of pollinators along with population growth and increasing agricultural activities hamper this mutual interaction. Nectar and pollen are the major reward for pollinators and flower morphology and volatiles mediate the specialized plant-pollinator interactions. Limited information is available on the volatile profiles attractive to honey bees and bumblebees. In this study we analyzed the volatile organic compounds of the flowers of 9 different plant species that are predominantly visited by honey bees and bumblebees. The chemical compositions of the volatiles were determined using a head space gas chromatography-mass spectrometry (GC-MS) method, designed to understand the plant-pollinator chemical interaction. Results: Results showed the monoterpene 1,3,6-octatriene, 3,7-dimethyl-, (E) (E-𝞫-ocimene) was the dominating compound in most flowers analyzed, e.g., in proportion of 60.3% in Lonicera japonica, 48.8% in Diospyros lotus, 38.4% Amorpha fruticosa and 23.7% in Robinia pseudoacacia. Ailanthus altissima exhibited other monoterpenes such as 3,7-dimethyl-1,6-octadien-3-ol (𝞫-linalool) (39.1%) and (5E)-3,5-dimethylocta-1,5,7-trien-3-ol (hotrienol) (32.1%) as predominant compounds. Nitrogen containing volatile organic compounds (VOCs) were occurring principally in Corydalis speciosa; 1H-pyrrole, 2,3-dimethyl- (50.0%) and pyrimidine, 2-methyl- (40.2%), and in Diospyros kaki; 1-triazene, 3,3-dimethyl-1-phenyl (40.5%). Ligustrum obtusifolium flower scent contains isopropoxycarbamic acid, ethyl ester (21.1%) and n-octane (13.4%) as major compounds. In Castanea crenata the preeminent compound is 1-phenylethanone (acetophenone) (46.7%). Conclusions: Olfactory cues are important for pollinators to locate their floral resources. Based on our results we conclude monoterpenes might be used as major chemical mediators attractive to both honey bees and bumblebees to their host flowers. However, the mode of action of these chemicals and possible synergistic effects for olfaction need further investigation.

  • Propolis is made by bees collecting protective material or essence of plants and mixing with saliva and enzymes produced by the salivary glands. It is used to repair the inside of the honeycomb, keep it sterile, and adjust the temperature and humidity. Propolis is a natural antibiotic substance that it is used to make a clean room by coating the cell before the queen bee lay eggs, and preventing the bacteria from invading by using with wax when sealing the nursery room. Propolis extract is a health functional food with antioxidant and oral antimicrobial effects. In order to use propolis in food, its active ingredients are extracted with ethanol. Water-soluble propolis was prepared by mixing and stirring honey and ethanol extracted propolis (EEP) solution. When 1kg of honey and 100ml of ethanol extracted propolis solution were mixed and stirred, the total flavonoid content of water-soluble propolis was $6.6{\pm}1.1mg/10g$, and the free radical scavenging effects of water-soluble propolis were 54 to 74%.
