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.

To investigate the attributes of seed germination of the plants for greening of river bank slope, low-temperature treatment, chemical treatment, plant hormones treatment, and stratification were conducted using the seeds of 6 herbs growing naturally around river banks, such as Setaria glauca and faberii, Imperata cylindrica var. koenigii, Miscanthus sinensis, Pennisetum alopecuroides, Lespedeza cuneata and the seeds of 3 shrubs, such as Lespedeza bicolor., Rosa multiflora, Spiraea prunifolia for. simpliciflora. The findings are as follows. In case of herbs, Setaria glauca and faberii. have stone seeds. In the treatment with $H_2SO_4$, they were germinated through dormancy breaking, even though there were some differences depending on immersion time, and the germination rate of Setaria faberii was a bit higher than that of Setaria glauca. The germination rate of Imperata cylindrica var. koenigii was low in the treatment with $GA_3$, NAA, and the plant hormone, but the seed germination rate has improved and the germination rate of Miscanthus sinensis and Pennisetum alopecuroides showed the improved seed germination rate in low temperature treatment. In case of Lespedeza cuneata and bicolor, the leguminous plants, the treatment with $H_2SO_4$ was most effective for the improvement of seed germination and the decrease in germination time. Only Spiraea prunifolia for. simpliciflora, the rose among 3 woody plants showed the seed germination rate above 50% without any additional treatment. Thus, it was thought to be appropriate for greening. Rosa multiflora showed the attribute of germination in a dark condition at low temperature through stratification, despite its low germination rate. Based on the results as above, with respect to the greening using directly collected seeds, Miscanthus sinensis, Pennisetum alopecuroides, and Spiraea prunifolia for. simpliciflora are suitable for greening, because they do not need any additional treatment, and Lespedeza cuneata and bicolor are also suitable for greening because it is possible to improve the germination rate and reduce the germination time through the treatment on the seeds before sowing.

조직배양 감자줄기를 1/3 MS 액체배지가 첨가된 18 L 바이오리액터 배양기에서 배양하였을 때 생중량 증식이 가장 양호하였고, 1/4 MS 액체배지, 1/2 MS 액체배지 순으로 감자줄기의 생중량이 증가하였다. 감자 소괴경 형성은 감자줄기를 배양한 바이오리액터에서 배지를 따라 내고, 소괴경 형성용 배지로 교환하여 어두운 곳에서 암배양하면 소괴경이 형성되었다. 소괴경은 암배양 1주후부터 줄기 마디의 측아에서 생성되기 시작하여 3주 정도에 대부분이 형성되고 1.5 MS 액체배지와 $20^{\circ}C$ 온도 조건이 최적이었다. 이 조건에서는 6주 정도 배양하면 18L 바이오리액터 배양기에서 1,000개 이상의 소괴경을 생산할 수 있었다. 어두운 배양조건에서 소괴경이 거의 성장하면 바이오리액터를 빛이 있는 조건으로 옮겨 1주정도 배양한 후 녹화된 소괴경를 수확하였다.

본 연구는 광량이 산호수(Ardisia pusilla), 크루시아(Clusia rosea), 팔손이(Fatsia japonica) 목본식물 3종의 초기 생육 반응에 미치는 영향을 구명하고자 수행하였다. 목본식물 3종을 10cm 포트에 식재한 다음, 광량 15, 30, 60, $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD 4수준으로 광조사 시간은 12/12(명기/암기)로 설정하여 120일 동안 실시하였다. 4주 간격으로 초고, 엽장, 엽폭, 엽록소형광(Fv/Fm), SPAD, Hunter 값의 생육측정과 실험 종료 후 식물체 지상부와 지하부의 생체중과 건조중을 측정하였다. $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서 실험기간동안 초고, 엽면적, 지상부와 지하부의 생체중과 건조중 값이 가장 크게 나타났다. 팔손이는 광량이 높을수록 엽장, 엽폭이 컸으며, 그 밖의 식물에서는 광량에 따른 유의적인 차이가 나타나지 않았다. 산호수의 Fv/Fm 값은 60, $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서 광량에 대한 스트레스를 받는 것으로 나타났으나, 그 밖의 식물과 광량에서는 Fv/Fm는 모두 정상 범위로 나타나, 스트레스를 받지 않았다. SPAD값은 $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서 크루시아만 유의적인 차이를 보였으며, 그 밖의 식물과 광량에서는 유의적인 차이가 나타나지 않았다. 산호수의 Hunter 값은 모든 광량에서 유의적인 차이가 없었으며, 크루시아는 $60{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서, 팔손이는 $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서 L, a, b값에 특이성이 나타났다. $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서 산호수 줄기의 성장 폭이 컸으며, 크루시아는 60과 $120{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$에서 지속적인 성장을 보여, 적정수준의 초고를 유지하기 위해서 이들은 $60{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$이하의 광량이 필요할 것으로 판단된다.

The purpose of this study was to select herbaceous plants that can be used for presenting various views and biodiversity on the extensive rooftop greening. Experiment plots were constructed in July 2005 on the rooftop of the Administration Building in the Seoul Women's University. For this experiment, planters were used to design rooftop greening. The size of a planter is 500mm${\times}$500mm${\times}$100mm and each planter has the water storage plate in the lower part of it. The soil was constructed by mixing pearlite, vermiculite, cocopeat, and leaf mold in the ratio of 6 : 2 : 1 : 1. The plot was divided into the watered plot and the dry plot. Since each plot was constructed 2 times, finally 4 planters were constructed in total. One hundred species were used for the experiment and 9 plants per species were planted in each planter. Plants were organized according to types of plants and the experiment used 86 native herbaceous plants, 6 herbs, and 8 foreign plants. The plots were monitored once a month, from July to November 2005. The length and width of plants were tape-measured and covering rate was calculated by CAD program. "SPSS 10.1" was used for a statistical analysis. The result showed no significant difference between the watered plots and the dry plots. In cases of some plants, there were statistically significant differences between the watered planter and dry planter such as follows : Astilbe chinensis and Polygonatum odoratum which are shade plants were measured as the highest value on the watered pots, and Aquilegia buergeriana, Chrysanthemum zawadskii, Calendula arvensis and Gypsophila cerastioides D.Don which are sunny plants were measured as the highest value on the dry plots. According to the final analysis of the data collected and observed for growth condition during the first year of the research, 51 species including Prunella vulgaris var. lilacina and Veronica linaiaefolia in native herbaceous plant, 5 species with Lavandula angustifolia in herbs, and 3 species with Lantana camara and Muscari armeniacum in foreign plants showed the highest growth condition. In conclusion, it is suggested that various plants including sedums could be effectively used for extensive rooftop greening to improve landscape(a view) of the rooftop and increase ecological values.
