  • Red pine (Pinus densiflora) is widely used traditional medicine, pharmacological and nutritional values from which the phytochemical compounds are derived. The present study was aimed to examine the antibacterial effects in the absence and presence of a immature red pine cone extract against 13 microorganisms. The components in the aqueous extract from immature red pine cone were identified by GC-MS. About 1.4% of total polyphenolic compound was measured in aqueous extract collected from immature red pine cone. Also, the high concentration of ${\beta}$-phellenandrene, ${\alpha}$-pinene, limonene, bornyl acetate and aldehyde was detected in total ion chromatograms. Of total 13 microorganisms, 4 microorganisms including Pseudomonas aeruginosa, Vibrio cholera, Listeria monocytogenes, Klebsiella pneumonia were effectively killed by aqueous extract of immature red pine cone. The highest anti-bacterial effect was detected in P. aeruginosa, followed by V. cholera, L. monocytogenes and K. pneumonia. In case of P. aeruginosa, the largest diameter of inhibition zone was maintained to 1/2 solution treated cells and slightly decreased at 1/4 and 1/8 solution treated cells. Also, in test used V. cholera and L. monocytogenes, the inhibition zone was strongly formed in only 1 and 1/2 solution treated cells, while K. pneumonia showed the very small diameter of inhibition zone in all concentrations. Therefore, these results suggested that the aqueous extracts of immature red pine cone should be considered as a new and potentially important anti-bacterial substrate to effectively prevent the microbial infection and penetration.

  • Wetlands exhibit intermediate characteristics of both terrestrial and aquatic ecosystems, and the biodiversity is rich in these unique biological habitats. The symbiotic relationships between plants and fungi that inhabit these wetlands play an important role in natural resource management, biodiversity, and conservation. Accordingly, the mujechi, having academic value for the study of the natural environment, was investigated in terms of genetic diversity of endophytic fungi, which inhabit the roots of wild plants. The internal transcribed spacer (ITS) region was amplified to identify fungal strains. In total, 226 strains were isolated and categorized into three phyla, seven classes, 10 orders, 22 families, and 31 genera. In plants by endophytic fungi were classified in Isachne globosa (Ig) to 19 genera, Scirpus karuisawensis (Sk) to 11 genera, Utricularia racemosa (Ur) to 19 genera, and one incertae sedis, Eriocaulon decemflorum (Ed) to 11 genera. The fungal taxa was identified the genera Acephala (19.9%), Tolypocladium (16.3%), Neopestalotiopsis (11.5%), and Perenniporia (7.1%). The fungal group isolated from Isachne globosa (Ig) grew the largest number of isolated fungal strains. After comprehensive evaluation, the endophytic fungal group from Utricularia racemosa (Ur) ranked highest in diversity analyses. From the roots of wild plant in mujechi-neup, it confirmed the distribution and diversity of endophytic fungi. This study provides the basic data to understand fungal community structure in peat wetlands.

  • This study examined and analyzed ancient writing and poetry regarding cases of appreciating plants by using pots in a garden of a palace or private houses by ancestors, and examined shape and planting method of plant species and potted plants, arrangement and preference of potted plants. As for the method of the study, description research method which examines and interprets poem and painting based on potted plants. The results of this study is summarized like the following. First, the plants which were favorably used for potted plants include 19 kinds such as Prunus mume, Pinus densiflora, Pinus pumila, Phyllostachys spp., Camellia japonica, Punica granatum, and Gardenia jasminoidesa, and as for herbs, 12 kinds such as Chrysanthemum monifolium and Nelumbo nusifera . Second, the species which were specially arranged into artificial shapes include Prunus mume and Pinus densiflora. The two plants made the shape of severe curves of stems such as Wangpi. Gyuban, and Bangan, and there are Pinus densiflora dwarfed potted plant whose roots are stretched on Prunus mume grafted into a strange stump and an oddly shaped stone. For the beauty of the dwarfed tree shape, pine cones are added to an old Pinus densiflora or Parthenocissus tricuspidata is planted to stems, and additional method of making moss on the soil, which is called 'Jongbunchuigyeong'. As for planting method, water culture, planting on a stone, planting on a charcoal, and assembled planting are expressed in poetry. Third, as for external space for potted plants, a place where a king stays, a bed room for a king, surrounding areas and gardens of private houses, and step stones were used as a space which adds artistic effects. Potted plants are placed on a table in a library, on a desk, on a drawer, and near a pillow as a small items in a room, and scholars enjoyed original characteristics and symbolism of the potted plants. Fourth, at the time of flowering of Prunus mume, poetry event was held to enjoy the tree and writing poetry begun. And at the time of flowering of Chrysanthemum monifolium, the flowers were floated in a liquor glass or shadow play was enjoyed. Fifth, potted plants played the role of garden ornaments in elegant events of a palace, the gentry, wedding ceremony, and sacrificial rites. Sixth, potted plants were used as tributes between countries, donation to a king, or a gift of a king. In addition, there were many cases where scholars exchanged potted plants and there is the first record of giving a potted plant in 'Mokeunsigo' by Mokeun Isaek, scholar in the late era of Goryeo. Seventh, at the time of flowering Prunus mume, Chrysanthemum monifolium, Gardenia jasminoides, Nelumbo nusifera, and Narcissustazetta var. chinensis, they enjoyed the particular fragrance and express it into poetry. Eighth, plant species from southern parts such as Camellia japonica, Daphne odora, Gardenia jasminoides, Citrus unshiu, Phyllostachys spp., Punica granatum, Rosa rugosa, and Musa basjoo, or foreign plant species, and species weak against the cold were utilized as pot plants for enjoying green trees indoors in northern central province in harshly cold winter.

  • Vegetation structure of the vascular plants was investigated from March 2003 to October 2003 in Haepyeong wetland, Gumi-si, Gyeongsangbuk-do, Korea. Actual vegetation of Haepyeong wetland largely can be classified by floristic composition and physiognomy into 18 communities; Xanthium strumarium-Digitaria sanguinalis, Humulus japonicus, Persicaria perfoliata-Humulus japonicus, Phragmites japonica-Miscanthus sacchariflorus, Persicaria hydropiper-Phragmites communis, Persicaria hydropiper, Phragmites japonica-Persicaria hydropiper, Miscanthus sacchariflorus- Phragmites japonica, Persicaria hydropiper-Phragmites japonica, Miscanthus sacchariflorus-Salix glandulosa, Salix nipponica-Salix glandulosa, Salix nipponica-Salix koreensis, Salix nipponica, Miscanthus sacchariflorus-Salix nipponica, Phalaris arundinacea-Salix nipponica, Salix glandulosa-Salix nipponica, Trapa japonica, and Ceratophyllum demersum-Trapa japonica. Among them, the area of the Salix nipponica-Salix koreensis community was the largest as 122.2ha(9.23%). The dominant vegetation type was Miscanthus sacchariflorus-Persicaria hydropiper community based on phytosociological method, and it was was classified into three subcommunities; Salix glandulosa-Salix nipponica subcommunity, Digitaria sanguinalis subcommunity, and Cyperus amuricus subcommunity. Differential species of Salix glandulosa-Salix nipponica subcommunity were Salix nipponica, S. glandulosa, S. koreensis, Scirpus radicans, Persicaria maackiana, and Achyranthes japonica; differential species of Digitaria sanguinalis subcommunity were D. sanguinalis, Setaria viridis, Ambrosia artemisiifolia var. elatior, and Cyperus orthostachyus; differential species of Xanthium strumarium subcommunity were X. strumarium, Acalypha australis, Erigeron canadensis, Echinochloa crus-galli, and Vicia tetrasperma. Zonation of vascular hydrophytes and hygrophytes was as followers: Salix glandulosa, S. koreensis, S. nipponica were distributed in the region of land which water table is low, and Persicaria maackiana, Persicaria hydropiper, Scirpus radicans were distributed in the understory. And emergent plants such as Phragmites communis and Scirpus karuizawensis, floating-leaved plant such as Trapa japonica, submersed plant such as Ceratophyllum demersum, and free floating plant such as Spirodela polyrhiza formed the zonation from shoreline to water. The specified wild plants designated by the Korean Association for Conservation of Nature, Ministry of Forest, and Ministry of Environment were not distributed in the study area. It was expected that Haepyeong Wetland worthy of conservation contributed purifying water pollution, giving habitats of many lifes, and providing beautiful scenes of the river.
