  • Two newly recorded alien plants Geranium dissectum L. (Geraniaceae) and Dianthus armeria L. (Caryophyllaceae) have been found in Seogwipo-si, Jeju-do and in Hapcheon-gun, Gyeongsangnam-do, of South Korea, respectively. Geranium dissectum can be easily distinguished from other related Korean taxa by fruit with glandular hairs and distinctly reticulated seeds. Dianthus armeria can also be distinguished from other related Korean taxa by its cyme and pubescent calyx. We provide descriptions of the morphological characters, illustrations, photographs and a key to allied taxa.

  • The purpose of this study is to select suitable planting base for the mat-type rooftop greening in order to popularize rooftop greening system easily. The experiment was conducted from 2004 June to 2005 May under several conditions; 4 soil depths under mats(2cm, 5cm, 10cm, 15cm), two soil mixtures(natural soil 80%+leaf mold 20%, artificial soil) and two light conditions(full sun place, 20% shaded place). In this experiment, 3 types of mats were used ; the herbaceous plants mat(11 plants inclusive of Lotus corniculatus L., Silene armeria L.), the lawn mat with Festica arundinacea and Sedum mat with Sedum kamtschaticum, Sedum sarmentosum, Sedum oryzifolium, Sedum middendorffianum. The result is as follows; in the mat-type rooftop greening, the herbaceous plants mat, lawn mat and sedum mat are the similar number of plant and effect of greening on soil depth 2cm, 5cm and 10cm, 15cm. So suitable soil depth of rooftop greening is 10cm for the load and economical factor. Thus the mat-type rooftop greening possible planting base depth of all 13cm as soil depth 10cm and mat depth 3cm. As soil mixtures, the number and growth of plants were better mat and 'natural soil 80% +leaf mold 20%' than mat and artificial soil. In herbaceous plants mat, Silene armeria L., Dianthus chinensis, Centaurea cyanus L., Lotus corniculatus L. are survival in full sun place and Silene armeria L., Dianthus chinensis, Centaurea cyanus L. are survival in 20% shaded place. In conclusion, selection of suitable soil mixtures and plants is possible extensive management rooftop greening with effect of continuous greening. The mat-type rooftop greening are lightweight and simple preparation without management and can popularize readily.

  • The study was to introduce the revegetation measures for the improvement of the landscape in October, 2012 on the slope; two and four years after the introduction, the slope was examined to see the status of the revegetation. The result is as follows. The result from examining the soil on the slope, the soil was Loamy sand; which infers that the soil is in a poor condition for improving the scenery. Examining the characteristics of the vegetation-base materials, the soil acidity was pH 6.4 to 6.7; and the soil hardness was 21 to 24mm (hardness quotient of soil), this can be considered a favourable condition, which has no effect on the growth and development of plants. When it comes to the discovery of the species in the area, Lotus corniculatus var., Silene armeria L., Papaver rhoeas, Trifolium pratense L. developed and grew in spring after two years. And in the summer, Lotus corniculatus var., Dianthus chinensis L., Cosmos bipinnatus, Coreopsis drummondii L., Trifolium pratense were founded. And there were Lotus corniculatus var., Dianthus chinensis L., Aster yomena, Coreopsis tinctoria, Trifolium pratense L. in the autumn. According to the examination conducting after four years, Lotus corniculatus var., Dianthus chinensis L., Silene armeria, Cosmos bipinnatus, Coreopsis drummondii L., Papaver rhoeas, Trifolium pratense L. were founded in the spring, and Lotus corniculatus var., Dianthus chinensis L., Cosmos bipinnatus, Coreopsis drummondii L., Trifolium pratense grew in the summer. Lotus corniculatus var., Dianthus chinensis L., Astragalus sinicus, Aster yomena, Coreopsis tinctoria, Trifolium pratense L. were discovered in the autumn. Among the exotic species founded in the area, were Festuca arundinacea, Lolium perenne, Festuca rubra. When it comes to the protection of vegetation and dominance, Lotus corniculatus var., Metaplexis japonica, Coreopsis drummondii L. are the dominant species among the spring plants; and Lotus corniculatus var., Trifolium repens L., Erigeron annuus (L.) Pers. were the dominant plants in the summer. In the autumn, Lotus corniculatus var., Coreopsis drummondii L., Poa pratensis appear to be the dominant plants. The colonies of Pinus densiflora and Castanea crenata var. were formed around the South Sejong IC. Part of the area is occupied by the colony of Alnus hirsuta Turcz. ex Rupr. In terms of shrub, there were Indigofera pseudo-tinctoria, Robinia pseudoacacia, and Rosa polyantha var. genuina NAKA. As ground cover plants, Sasa borealis, Rubus crataegifolius Bunge were founded.

  • The purpose of this study was to suggest the possibility of utilizing the wildflower pasture for promoting public interest. Growth characteristics, botanical composition, fauna distribution on wildflower pastures were observed. The experimental design included two treatments: native wildflower pasture(NWP, turf grasses 6 species + native wildflower 11 species) and introduced wildflower pasture(lWP, turf grasses 6 species + introduced wildflower 9 species). The field trials were carried out on the experimental pasture plots at Chungnam National University from 1997 to 2000. The results obtained are as follows: 1. The flowering of wildflower was maintained continuously from May to September, and the colors of wildflowers; varied seasonally during this period. With native flowers, however, Hemerocallis fulva, Belamcanda chinenis and Aster koraiensisi showed problems in lately germination and early establishment. Meanwhile, Introduced wildflower showed not only excellent germination and early establishment compared to native flowers species but also maintained brighter colors. But Coreopsis tinctoria, Achillea mi/lefolium and Rudbeckia bicolor had colonized at a higher height or possessed stronger rhizome. 2. The appropriate species of turf grass which maintained continuous seasonal distribution are thought to be tall fescue, perennial ryegrass. Kentucky bluegrass in NWP and IWP. 3. Botanical composition of wild flower in NWP was arranged in the order of Achillea sibirica > Lotus corniculatus var. Japonicus > Dianthus chinensis > Plantago asiatica > Taraxacum pla~ycarpum > Viola mandshurica > Aster koraiensis > Vicia tetasperma > Lespedeza stipulacea > Hemerocallis fulva, respectively. The highest seasonal distribution of native wildflower, Achillea sibirica was in spring and summer, Lotus corniculatus var. Japonicus was in autumn. Botanical composition of wild flower in IWP was arranged in the order of Achillea millefolium Coreopsis tinctoria > Silene armeria > Coreopsis lanceolata > Rudbeckia bicolor > Sanguisorba oficinalis > Centaurea cyanus > Chrysanthemum leucanthemum > Dianthus petraeus, respectively. The highest seasonal distribution of introduced wildflower, Silene armeria was in spring, Achillea millefolium was in summer, and Coreopsis tinctoria was in autumn.
