To obtain pure lines for breeding $F_1$ varieties of spreading surfinia and wave petunia, Petunia ${\times}$ hybrida, 20 lines of surfinia petunia and 28 lines of wave petunia that were considered uniform in growth and flowering characteristics were selected by self-pollination of the fifth($S_5$) or the seventh generation($S_7$). The 20 selected lines of surfinia petunia had the branch number ranged from 6.0 to 11.0 cm, and the internode length ranged from 2.0 to 4.2 cm. Among them, ten lines, including '$Pe99-017^7$' were above 60 cm of plant width, above 300 leaves in a plant. Fourteen lines including '$Pe99-017^7$' were more than 150 in the number of flower. In the petal color, thirteen lines, including '$Pe99-017^7$', were red-purple; three, including '$Pe99-007^7$', were purple; '$Pe04-086^7$' and '$Pe04-159^7$' were violet; and line '$Pe072-1^7$' was white. Eight lines including '$Pe02-205-2^5$' ranged from 4.0 to 5.0 cm of flowers diameter, and seven lines including '$Pe04-086^5$' ranged from 3.0 to 4.0 cm of leaf length, which is relatively low. Germination rate of the lines was more than 50%. In the wave petunia, the branch number of the 28 selected lines ranged from 8.0 to 13.0 cm, and the internode length ranged from 1.0 to 3.2 cm, which is relatively higher than surfinia petunias. Among them, ten lines, including '$Pe99-020^7$' were above 60 cm of plant width, above 200 leaves in a plant. Twelve lines including '$Pe04-034-2^5$' were more than 150 in the number of flower. In the petal color, eighteen lines, including '$Pe99-020^7$', were red-purple; three, including '$Pe04-113-4^5$', were red; three, including '$Pe04-263^5$', were white; '$Pe04-201^5$' and '$Pe04-263^5$' were violet blue; and line '$Pe04-072-5^5$' was purple. Nine lines including '$Pe04-201^5$' ranged from 4.0 to 5.0 cm of flowers diameter, and eleven lines including '$Pe04-263^5$' ranged from 3.0 to 4.0 cm of leaf length, which is relatively low. All the lines with various growth and flowering characteristics would be very promising to use as breeding materials for $F_1$ hybrids of spreading petunia, Petunia ${\times}$ hybrida.

To improve the physical and chemical properties of the soil and increasing water-retaining property of the soil, Superabsorbent synthetic polymeric materials have been used. The experiment carried out from April to July 2012 after the influence evaluation of Superabsorbent synthetic polymeric materials to vines plant. The result shows that the study of Hedera japonica Tobler, the growth and the survival rates rank as media > hydroponic > superabsorbent synthetic polymers, and the growth and the survival rates are considerably pessimistic in the experiment of hydroponic and superabsorbent synthetic polymers. In the study of Trachelospermum asiaticum var. intermedium, the growth and the survival rates rank as hydroponic > media > superabsorbent synthetic polymers, the difference between the experiment of hydroponic and is very small and the survival rates are not very good in the experiment of superabsorbent synthetic polymers. In the study of Euonymus fortunei var. radicans Rehder,it is insignificantly difference among the different of planting based. Judging from these results, the differences are depending on the species of plants. The thesis holds that the characteristics of plant should be considered in plant cultivation and soil improvement in the future, and it is desirable to use the appropriate mixing ratio of soil in soil improvement as well.

We isolated endophytic fungi from Smilax china and Cryptomeria japonica. These fungal strains were identified based on their morphological characteristics and phylogenetic analyses of their internal transcribed spacer, large subunit rDNA, and translation elongation factor 1-α DNA. Among them, we discovered two fungi belonging to the genus Phyllosticta, which have not been previously recorded in Korea. We have described these two fungal strains, Phyllosticta ericarum 19E458 and Phyllosticta philoprina 19E012 in this study.

Genetic variation in Asaum misandrum, a woodland herb in Korea, was investigated based on allozyme analysis with starch gel electrophoresis. All of previously reported populations in Korea were sampled and seven loci from six enzymes were analyzed. Overall genetic variation of A. misandrum population showed considerably high levels of genetic variation within the species (A = 2.05, P = 71.4, $H_E$ = 0.294). A positive $F_{IS}$ value of A. misandrum indicated overall deficiency of heterozygotes, and a low $F_{ST}$ value (0.112) meant very little differentiation among populations. Factors contributing to the high levels of genetic diversity found within populations of A. misandrum include population maintenance via wide distribution range from Korea to Japan and primarily outcrossing breeding system. Although it showed moderate genetic diversity level, most habitats of the species were scattered and discontinuous. Besides, low numbers of individuals were found in the most habitats and individuals are collected frequently from the wild due to the unique shape of the flowers as well as the rarity of the species. Thus, there is a need to set up a reasonable conservation strategies including the maintenance mechanism of genetic diversity of A. misandrum.

Forest vegetation types were studied by the phytosociological investigation and the TWINSPAN method in Ulleung Island, Korea. Two hundred thirty-two releves were sampled with $100m^2$ plots. Two main vegetation types, the mountain forest(Acer okamotoanum community group) and maritime forest(Artemisia scoparia community group), have been distinguished and typified twenty-two vegetation units. The former was divided in 4 communities, 11 groups and 7 subgroups. The latter was 2 communities and 5 groups. In a case of life-forms of mountain and maritime vegetation type, the composition ratio of species that had featured trees and herbs, hemicrypthophyte, a seed dispersion-type by wind or nature falling and erection form was high in the mountain vegetation type. Species that had featured shrubs, chamaephyte, disseminated mainly by a wind in the herbs, and animals and man or no special modification in the woody, narrowest extent of rhizomatous growth and the clonal growth by stolons and struck roots and procumbent form were abundantly distributed in the maritime bluff vegetation type. Particularly, the composition ratio of Sambucus sieboldiana var. pendula community(A6), disturbed vegetation type of middle-lower slope of mountain, that had featured a seed dispersion-type by wind, moderate and narrowest extent of rhizomatous growth and Tussock form was high.

We report a newly found natural habitat of Abeliophyllum distichum in mountainous slope range of Yeongdong-gun, Chungbuk Province. Abeliophyllum distichum Nakai is one of the Korean monotypic endemic species. Natural growth habitats of this species have been recorded from seven sites up to now, and all of the natural habitats are located in middle (Chungbuk Prov.) and middle west (Jeonbuk Prov.) parts of South Korea. Among the previously recorded seven natural habitats, six sites have been designated as Korean national monuments and protected with in situ conservation. New natural habitat of A. distichum is located on northwest slope of stiff hillock area beside the small stream, Seolgye-ri, Yeongdong-eup, Yeongdong-gun, Chungbuk Province. Total growing area is nearly $3,000 m^2$. It is 10-25 cm in soil depth and pH 5.0-6.5 in soil acidity in that area. And many of A. distichum are clustered with 2-5 individuals extended by stoloniferous asexual reproduction. And the total numbers of A. distichum are about 700 individuals with only typical white flowers, and the ratio between pin type and thrum type is 37% and 63%, respectively. The huge population of A. distichum is growing with Quercus mongolica-Fraxinus rhynchophylla association in a mixed forest, and it shows high affinity with Stephanandra incisa, Ligustrum obtusifolium, Euonymus alatus for. ciliatodentatus, and Smilax sieboldi.

The radical scavenging activities of 9 medicinal plants on peroxynitrite ($ONOO^-$) and hydroxyl (${\cdot}OH$) radical were investigated using in vitro system. The water extracts of 9 medicinal plants showed the protective effect against $ONOO^-$ and ${\cdot}OH$ radical. In particular, Akebia quinata, Aster scaber, Cudrania tricuspidata, Diospyros kaki, Eriobotrya japonica, Lycium chinense, Parthenocissus tricuspidata and Polygonum aviculare exhibited $ONOO^-$-scavenging activity by about 50% at the concentration of $10{\mu}g/ml$. Although those $ONOO^-$-scavenging activities were lower than that of penicillamine (94.08${\pm}$3.04%) as a positive control, Eriobotrya japonica (89.87${\pm}$4.57%) was the most potent scavenger of $ONOO^-$ at the concentration of $10{\mu}g/ml$. Also, Diospyros kaki and Urtica angustifolia showed the strong${\cdot}$OH-scavenging activity than thiourea, positive control, at the concentration of lmg/ml. Our results indicate that 9medicinal plants may act as free radical scavengers and reduce damages caused by oxidative stress associated with $ONOO^-$ and${\cdot}$OH radical.

The purpose of the study aimed to explore the possibility for natural preservative convergence materials by examining the antioxidant activity and antimicrobial effect of 19 wild plants in Jiri Mountain. Total polyphenols were higher in the order of CS(Camellia sinensis L., 87.9 mg GAE/ g), MP(Mentha piperascens Holmes., 85.1 mg), NN(Nelumbo nucifera Gaertn., 65.0 mg) and PD(Pinus densiflora Siebold & Zucc., 52.8 mg). Total flavonoids were high in NN(25.7 mg QUE / g) and MP (25.4 mg QUE / g). CS(58.1%), NN(47.9%), and MP(40.6%) showed high ABTS radical scavenging ability and the result was similar in DPPH radical scavenging ability. The extracts of HC(Hemerocallis coreana Nakai.), PD, and CO(Cornus officinalis Siebold et Zucc.) showed the highest inhibitory effect on the growth of E. coli. The extracts of PK(Pulsatilla koreana Nakai ex Nakai.), SC(Saururus chinensis Baill.), and MC(Smilax china L.) completely inhibited the proliferation of S. aureus, showing the possibility to be developed as natural preservatives and disinfectants.

Computer automation, developed into a major element of modern industry, has also brought to great change in textile design field. Traditional textile designers have been created patterns by free hand drawing with brush. The modern textile designers create and present, on the other hand, printed or woven designs much more utilizing extensively the computer cad as design tool, creating various designs and colors as well as reducing the creative process. Vine pattern the worldwide known is not a pattern simplified from a specific plant but it is rather a plant imaginative pattern that has been developed from a winter plant found in ancient Egypt. Vine patterns express gorgeous curve lines, which are simple but decorative by connecting flowers or leaves with stems. These vine patterns have also been widely used for their decorative arts in Korea since early times because they were believe to a favorable auspice pattern symbolizing a long-life and fertility. In this study, the possibility of developing various designs is explored and presented by utilizing the motif of vine pattern in CAD program.
