  • This experiment was conducted to investigate the quality of wild flowers and mixed wild flower silages. Silage materials employed ochardgrass and mixed wild flower (orchardgrass, white clover, Achillea sibirica Ledeb., Coreopsistinctoria Nutt., Rudbeckiabicolor Nutt., Centaureacyanus L.). Six kilograms of silage materials cut from each treatment were divided into 3 containers, packed by vacuum, and fermented for 40 days. The orchardgrass silage showed significantly higher contents of crude protein than that of mixed wild flower silage. But the neutral detergent fiber and acid detergent fiber contents of orchardgrass silage were significantly lower than those of mixed wild flower silage. pH and butyric acid of orchardgrass silage were significantly lower than those of mixed wild flower silage, and significantly higher in lactic acid contents. It appears that water soluble carbohydrates needs to be supplemented, being grounded on the results above, into wild flower materials both with high fiber materials and with low substances which need lactic acid fermentation.

  • To develope wild flower collected from Chollabuk-do area resource plant species were investigated from May 1996 to April 1997. This study was focussed to make the basic data for better quality of breeding species from wild flower species and to keep proper gene pool for development with competitive power internationally in future. There was 131 species blooming in spring season(34.7%), 219 species in summer(58.1%), 25 species in autumn(6.6%) and 2 species in winter(0.5%), respectively. Flower color of all the plants was 26 kinds in diverse, among them, white flowers were occupied dominantly of 28.9%, yellow flowers, 20.7%, violet flowers, 16.4% and red purple flowers, 7.9%, respectively. Transplanted wild flower plants at the garden in the study area frequently were Chelidonium majus var. asiaticum, Hemerocallis fulva, Iris nertschinskia, Rhododendron yedoense var. poukhanense, Rhododendron mucronulatum, Pulsatilla koreana, Chrysanthemum zawadskii var. latilobum, Taraxacum platycarpum, Chrysanthemum boreale, Liriope platyphylla and Lycoris radiata. Twenty-six species of wild flowers such as Cymbidium goeringii, H. fulva, L. radiata, C. zawadskii var. latilobum, etc. were collected from their habitat and being selling at the market or road side. Total 343 taxa of wild flowers to prevent carrying out to foreign countries and to improve better quality were selected and recommended in this study, for example, they were 41 taxa of Compositae plant, 25 of Rosaceae, 20 of Liliaceae and 18 of Ranunculaceae in order. Acorus calamus var. angustatus, Cypripedium japonicum, C. macranthum, Calanthe discolor, Dicentra spectabilis, Ilex cornuta, Stewartia koreana, Abeliophyllum distichum, Forsythia saxatilis and Campanula glomerata var. dahurica should be protected as wild flowers because their numbers are decreasing remarkably, belong to rare species, being at a crisis to extinct species and important plants for research materials.

  • Background: Ginsenosides are the major effective ingredients responsible for the pharmacological effects of ginseng. Malonyl ginsenosides are natural ginsenosides that contain a malonyl group attached to a glucose unit of the corresponding neutral ginsenosides. Methods: Medium-pressure liquid chromatography and semipreparative high-performance liquid chromatography were used to isolate purified compounds and their structures determined by extensive one-dimensional- and two-dimensional nuclear magnetic resonance (NMR) experiments. Results: A new saponin, namely malonyl-ginsenoside Re, was isolated from the fresh flower buds of Panax ginseng, along with malonyl-ginsenosides Rb1, Rb2, Rc, Rd. Some assignments for previously published $^1H$- and $^{13}C$-NMR spectra were found to be inaccurate. Conclusion: This study reports the complete NMR assignment of malonyl-ginsenoside Re, $Rb_1$, $Rb_2$, Rc, and Rd for the first time.

  • Diffusion of non-professional flower growing in Korea still lags behind. The objectives of the study are to establish a theoretical modes to explain the diffusion of social floriculture, to identify some characteristics and problems of growing flower crops to cultivate amenities and emotions, and to suggest remedial measures for fostering it. Theoretical model adopted in this study consists of such variables as education, social movement, policies, diffusion of social flower growing, amenities, and emotional cultivation. For identifying the diffusion characteristics of flower growing, projects implemented by a non-governmental organization, schools, local and central government organizations were analyzed. In order to stimulate the diffusion of social flower growing and to increase its effects, there needs to strengthen education of stakeholders, establishment of partnership among schools, non-governmental and governmental organizations, and institutional supports including manpower and finances. Linking flower growing projects to community festival and tourism development programs can foster institutionalization of community flower growing. Furthermore, the introduction of wild, symbolic and traditional flowers and trees will help to specialize and improve community landscapes.

  • Pollinators play important roles for crop production as well as maintenance of wild plants' reproduction. Pollinator dependency in Korean agriculture have increased, but the degradation of habitat quality pose significant threats to pollination in agroecosystem. Provisioning flower habitat is one of the major activities to increase pollinator abundance and richness. We tested the effect of flower habitat supplementation on the pollinator, pest and natural enemy abundance in pepper field. Results showed that Hymenopteran pollinators were more abundant in the pepper plots close to the flower habitat. Among natural enemies, the similar pattern from pollinators was observed to parasitoids in the family of Eulophidae, but not to those of Ichneumonidae. There were no statistically significant differences of insect pests like aphids and thrips, as well as pepper production among plots in the pepper field. Even limited spatial scale, this study showed supplementing the flowering plant habitat to the agricultural landscape could conserve and boost pollinators and natural enemies, and possibly resulting better fruit production by pollination service.

  • This study was conducted to investigate the germination rates and ground coverage rates of the 16 native wild flower, herbaceous, shrub and woody plants according to temperature and seeding timing for the revegetation and rehabilitation of the roadside slopes. Also, this study was conducted to suggest design criteria to select revegetation plants and to decide proper seed mixture for ecological restoration of the disturbed manmade slopes as a environmentally friendly construction. The results are summarized as follows. 1. Most of the plants germinated after 10~14 days. Woody plants germinated more slowly than wild flowers and herbaceous plants because of the hard seed. 2. Most of the plants showed the highest percentage of the germination rates under $15/25^{\circ}C$ temperature. The next was in order of under the $20/30^{\circ}C$ temperature, normal temperature(October) and $25/35^{\circ}C$ temperature. 3. At the chamber experiment, the Sorbaria sorbifolia var. stellipila showed the highest germination rates. Most of the native wild flowers germinated well and showed high germination rates under the various temperature. 4. As the field germination experiments, the seeding at August shows higher germination rates than that of the seeding at September, but showed lower surviving percentage of the germinated seedlings and lower ground coverage percentage than those of the seeding at September. After one year, Chionanthus retusus, Acer palmatum, Albizzia julibrissin are germinated and showed 10% coverage rates. So, they can be used as revegetation plants for the restoration works. 5. As seed mixture experiment, it was not effective only to increase the proportion of the ratio of the tree seeds, relatively high price, for making woody vegetation. It would be more successful to make vegetation structure by natural competition among wild flowers, shrubs and trees. 6. The excessive dominance of trees in revegetation works may destroy the lower layer of vegetation and it will be undesirable on the species diversity. It is more important to recover the species diversity of the plant community by seed mixture with the considering the germination, the growth characteristics and the correlation effect among revegetation plants. 7. To recover the manmade slopes quickly, increasing the ratio of the wild flower was recommended.

  • This study investigated the effective harvest of 'Kyoho' grapevines by examining their characteristics including bud development, necrosis types and flower primordium formation. The size of the axillary bud did not show any difference in the 5th node or more, but it was smaller because it was closer to the base in the 4th node or less. In the 1st node, the rates of main bud necrosis (MBN), accessory bud necrosis (ABN), and whole bud necrosis (WBN) were high, and the rate of flower primordium formation was low, but there was no significant difference in the other nodes. Therefore, it was expected that using other nodes than the 1st node would be advantageous to secure production. Because the growth progresses after sprouting, the main bud necrosis rate increases, showing a very low flower primordium formation rate in March of the following year. Therefore, a method is needed to increase the storage nutrients in the winter and the rate of flower primordium formation after March. This study found that the thickness of the shoots should be less than 8.5 mm between the 3rd and 4th nodes, and the length should be less than 60 cm for nodes up to the 10th node.

  • Corni fructus is often distributed or processed in the form of dried fruit. However, Corni fructus is hard to develop due to its distinctive sour, bitter, and astringent taste. The aim of this study was to develop a puree to broaden the utilization of fresh Corni fructus. Manufacturing and quality characteristics of Sansuyu jam made from puree were investigated. Seeded Corni fructus pulp consisted of 20 to 26% whole fruit. The moisture and sugar contents of pulp were 52~63% and $15{\sim}31^{\circ}Brix$, respectively. Sterilized distilled water was added to seeded pulp to achieve a constant solids content in the puree. As the pectin content was low as $0.14{\pm}0.01%$, gelling agent was added to produce jam. The moisture content of the puree increased to 83~88%. The sugar content was reduced to $10^{\circ}Brix$. There was no significant difference in pH. DPPH radical scavenging activities of the puree according to ripening rate at a concentration of 100 ppm were 47.92% and 50.96%, respectively. The preference degree was $5.03{\pm}0.97$ at a ripening ratio of 50:50, 2% pectin, and 0.2% carrageenan. These results imply that Corni fructus pulp puree may be appropriate for development as a natural food product.

  • Chilean wild flower seeds showed low germination rate and lacked germination uniformity. This experiment was conducted to find out the effects of light conditions, $GA_3$ (50 mg/L, 100 mg/L, 200 mg/L) and $KNO_3$ (0.1%, 0.2%, 0.4%) treatments on germination of five species of Chilean wild flower seeds. The seeds of $Schizanthus$ $candidus$, $Schizanthus$ $hookerii$, and $Schizanthus$ $litoralis$ did not germinated in light condition. The others did not show a significant different germination rate under light and dark conditions. The germination rate of $Mimulus$ $luteus$, $Schizanthus$ $candidus$, $Schizanthus$ $hookerii$ increased 2.3, 5.6, and 3.2 times compared with control, respectively in $GA_3$-200 mg/L treatment, but that of $Rhodophiala$ $ananuca$ enhanced slightly in $GA_3$-50 mg/L treatment. Those results suggested that the germination rate of Chilean wild flower seeds enhanced by $GA_3$ treatment that is very efficient in breaking seed dormancy.

  • This study was conducted to grasp distribution of native plants in flower market and uses of native plants in floral decoration. This study was investigated native plants sold in flower market(2017.01-2017.12) and their monthly sales. Also, this study analyzed the use of native plants, frequency of native plants classified by form and color of native plants used for floral decoration in flower magazines 'Fleur' and 'The Flower'. Among 172 species distributed cut-flower, native plants in Korea flower market are only 24 species(14.0%). Number of filler flower(15 species) is more than other forms. Native plants used in 'Fleur' and 'The Flower' were 14 species(10.2%) and 17 species(9.6%), it is meaning that native plants were less used than foreign plants. The number of filler flower was the highest in both magazines, but form flower(299 works) in 'Fleur' and mass flower(571 works) in 'The Flower' are used most frequently. According to color analysis of native plants used for floral decoration, P(purple), PB(navy) and RP(reddish purple) were 57% of the total. It can be increased native plants uses in flower decoration with developing form and mass flower considering color preference.
