The study was conducted to find out the harvesting time, storage duration, cold treatment and sterilization on seed germination of Miscanthus sinensis. The optimum harvesting time of the Miscanthus seed in native to Jeju island was December. And the seed germination passible 3 years after harvesting. When the seeds had cold treatment, seed germination nate was 74% rather than 63% of non-treatment. For seed sterilization treatment, soaking in solution of Benomyl 7% during from 3 hours to 12 hours germinated 9% over. But the non-treatment on 24 hours treatment reduced the seed germination of Miscanthus sinensis.

Korean native plants were investigated for their suitability to be used for floral clusters after drying. Floral clusters which were made in semi-sphere with a hand-tied method and can be fit in $22{\times}22{\times}37cm$ paper boxes were made with 37 species. Among 37 species, the 14 species which were easy to dry, to make floral clusters, and have not been used in other countries, were Echinochloa crus-galli var. frumentacea, Imperata cylindrica var. koenigii, Muhlenbergia huegelii, Phleum pratense, Setaria glauca, and Setaria viridis in Gramineae, Artemisia capillaris, Artemisia montana, and Chrysanthemum indicum in Compositae, Agastache rugosa, Elsholtzia ciliata, Elsholtzia splendens in Labiatae, Carex neurocarpa in Cyperaceae, and Vitex rotundifolia in Verbenaceae were used with leaves, flowers, and fruits. The suitable plants for a floral cluster in $22{\times}22{\times}37cm$ paper box, a wreath in $22{\times}22{\times}6cm$ paper box, and a flower arrangement in $22{\times}22{\times}22cm$ paper box, which were made to a set, were 10 species, that is Phragmites communis, Setaria glauca, Setaria viridis, Artemisia capillaris, Artemisia montana, Chrysanthemum indicum, Elsholtzia ciliata, Elsholtzia splendens, Mosla punctulata, and Vitex rotundifolia.

Contamination of soil by deicing salt is among the important environment problems due to their toxicity and negative impact to human health and the environment. One of the effective methods for cleaning the soil from deicing salts is desalination using soil amendment-phytoremediation continuum treatment. The purpose of this study was to determine how much of the pH, EC control and Ca²⁺, Na⁺, Mg²⁺, and K⁺ taken up soil amendments and Miscanthus sinensis, and to evaluate the effect of salt reduction and growth improvement as affected by soil amendment in high concentration of calcium chloride (CaCl₂) deicing salts. Results indicated that the addition of soil amendments was decrease the EC and pH, also significantly reduce the leaching of Ca²⁺, Na⁺, Mg²⁺, K⁺, a chloride ions related deicing salts, compared to the control for CaCl₂ 10 g/L treatment. It also resulted in an enhanced plant growth and higher plant height, leaf length, leaf width, number of leaves, fresh weight and dry weight in Hydroball treatment + Miscanthus sinensis planting continuum treatment compared to the treatment that planted Miscanthus sinensis only. Therefore, we concluded that soil amendments might be attributed to an accumulation of deicing slats in the roadside soil, resulting in the improvement of Miscanthus sinensis growth.

The purpose of this study was to understand plant community structure in upper zone of Gyeryongsan National Payk. Total 51 plots were set up and surveyed toy this study. The fifty one plots were classified into four communities such as Quereus mongolica community, Carpinus laxiflora community, Pinus densiflora community, and Quercus variabizis community. The Quercus mongotica community were found in 29 plots of the 51 plots and the differential species in the community weve Quercus mongolica, Acer pseudosieboldianum var. koreanum, Arisaema amurense var. serratum, Diarrhena japonica, and Saussurea gyacilis. The Carpinus laxiflora community were found in 10 plots of the 51 plots and the differential species in the community were Carpinus laxiflora, Carpinus cordata, Cornus eontroversa, Carex siderosticta, and Hydrangea serrata for. acuminata. The Pinus densiflora community were found in 7 plots of the 51 plots and the differential species in the community were Pinus densiflora, Lespedeza maximowiczii, Rubus crataegifotius, Miseanthus sinensis, Persicaria filiforme, Artemisia keiskeana, and spodiopogon sibiricus. the Quereus vuriabilis community were found in 5 plots of the 51 plots and the differential species in the community were Quercus variabilis.

This experiment was conducted to know what does the cutting date have an effect on the chemical composition and nutritive yield of Miscanthus sinensis, in order to determine the optimum cutting date of the plant when it is utilized as roughage. Miscanthus sinensis growing natively in the summit of Sam Ak mountain(550m above sea level) was cut at 10 days intervals from 25 July to 15 October, 1988. Plant length and dry matter contents were generally increased with delayed cutting date. Crude protein contents of the plant cut on 5, 15, and 25 of September were 5.5, 5.2 and 5.1%, respectively. Cmde fiber contents was similar with cutting treatment and averaged 35.6%. Cmde protein yield was higher in September than in other cutting date. Yield of crude fiber were 8.3, 9.3 and 9.3t/ha on 5, 15 and 25 September, respectively. Ratio of Cmde protein yield to Crude fiber yield on 5 September tended to be higher than on 15 September and 25 September. These results suggest that the optimum cutting date of the Miscanthus sinensis for good quality forage seems early September.

Importance value of Lespedeza cyrtobotrya in lower layer was the highest for in Samchang, and that of Rubus crataegifolius in other coal mine lands wast he highest. Importance value in herbaceous layer was the highest for Arundinella hirta in Samchang, for Corchoropsis tomentosa in Bongmyeong, for Miscanthus sinensis in Kabjeong, for Carex lanceolata and Artemisia princeps var. orientalis in Danbong coal mines, and Calamagrostis arundinacea in control site was the highest, respectively. Species diversity of middle and lower layer for four coal mine lands ranged from 0.201 to 0.666 and 0.612 to 0.895, respectively.

Major forest communities were as follows: 1. Pinus densiflora community 1) P. densiflora-Rhododendron mucronulatum subcommunity 2) P. densiflora-Lespedeza maximowiczii subcommunity 3) P. densiflora-Sasa borealis subcommunity 4) P. densiflora-Carex siderosticta subcommunity 2. Quercus mongolica community group. 1) Q. mongolica-Rhododendron schlippenbachii community a) Typical subcommunity b) Vaccinium koreanum subcommunity 2) Q. mongolica-Sasa borealis community 3) Q. mongolica-Lespedeza maximowiczii community 3. Quercus serrata community 4. Carpinus laxiflora-Quercus serrata community 5. Rhododendron tschonoskii community 6. Lespedeza crytobotrya-Miscanthus sinensis var. purpurascens community The map of DGN was drawn according to the actual vegetaton map. The ratio of DGN 7 and 8 was 93.9% in Gaya Mountain National Park.

This study was carried out to find the plant succession stage on highway cut-slopes. In order to analyze succession stage, plant survey with belt transect method was carried out in 1989 and 1995 at Joongbu-highway cut-slopes. The results could be summarized as follows ; The mean plant coverage of cut-slope was 78.3%. Plant coverage of Lower part area was higher than that of upper part area. Pioneer herb species on cut-slope were Miscanthus spp., Arundinella spp., Artemisia spp. etc., and pioneer woody species were Rubus crataegifolius, Robinia pseudoacacia, Pueraria thunbergiana, Pinus spp. etc. Also, among the introduced turf grasses, Eragrostis curvula is the pioneer species. Due to short of maintenance works, Zoysia japonica which has been planted by sodding work was found to decrease or diminish gradually. The ratio of pioneer stage plants, domestic and introduced herb species, seems to decrease, while the ratio of woody species which are advanced stage plants seems to increase. Maintenance works are needed to management and monitoring of plant succession on cut-slope, and use of herb and woody species will be effective.
