Research was initiated to investigate germination characteristics and germination pattern of 14 herbaceous plant entries used on the road slope during 30 days. An alternative germination condition for 14 herbaceous plant entries required by International Seed Testing Association(ISTA) was applied in the experiment, consisting of 8-hr light at $25^{\circ}C$ and 16-hr dark at $15^{\circ}C$. Significant differences were observed in the first germination rate(0.3%~40.7%)and in the final germination rate(7.7%~93.3%). Days to the first germination(2~8days), days to the 30% germination(2~6days) and days to the peak germination(6~18days) were different among 14 herbaceous plant entries in the study. From this result, we could find out higher final germination rate of 14 herbaceous plant entries in the following order; First, forage crops and cool-season turfgrasses; Second, herbeceous flowers; Third, wild plants. We could also divide germination rate among 14 herbaceous plant entries as 6 groups(I;very high, II;high, III;medium high, IV;medium low, V;low, VI;very low) based on the final germination rate and divide germination speed as 5 groups(A;very fast, B;fast, C;normal, D;slow, E;very slow)based on days to the peak germination. Considering germination characteristics and pattern of 14 herbaceous plant entries Medicago sativa, Lolium perenne, Festuca arundinacea and Cosmos sulphureus were regard as dominating species while Lespedeza cuneata, Silene armeria, Lotus corniculatus var.japonicus, Coreopsis tinctoria and Centaurea cyanus as competitive species following dominating species. However, Chrysanthemum burbankii, Pennisetum alopecuroides, Chrysanthemum boreale., Artemisia princeps var. orientalis and Arundinella hirta were not almost expected to emerge.

This research was studied to inverstigate the effect of plant mixtures and tackifibers on the vegetation of slope sites. 5 type plant mixtures(tree type, forest type, native herbaceous plant type, foreign herbaceous plant type, and cool-season turfgrass type) and 3 different tackifibers (Guar tackifibers, Polyarchrylamide tackifibers and Cellulose methyl starch) were treated with 3 replications on the experimented slope. The germination and coverage rate were high on native and foreign herbaceous plants and low on cool-season turfgrass, forest and tree types. We could notice that herbaceous plant types were effective on the vegetation of slope in the short term. Because tree or forest type vegetations similar to natural plant habitat, however, were preferable on slope vegetation in the long term, tree species of high germination rate should be selected in this experiment for tree or forest type slope vegetations. Tackifiber treatments increased the germination rate during the early treatment stage. However, the effect of tackifiber treatment on germination rate was decreased on the elapse of time. Guar tackifiber treatment was most effective on the vegetation of slope. As far as soil erosion control was concerned, all tackifiber treatments were effective compared to control.

The purpose of this study is to select the appropriate wild herbaceous plants on the rooftop. For the purpose of the experiments, 14 wild herbaceous plants were chosen. As the results of the experiments, the wild herbaceous plants growing on the culture soil(perlite) Among the 14 kinds of wild herbaceous plants, such as Chrysanthemum boreale, Taraxacum mongolicum, Aster Koraiensis, Aster yomena, Oenothera odorata, Oenothera lamarckiana, Patrinia scabiosaefolia showed good effects on growth of above ground parts. Therefore, these plants will effective for the rooftop revegetation. Callistephus chinensis and Lotus corniculatus var. Japonicus showed good height growth, wherase covering rate was worst. Chrysanthemum boreale, Platycodon grandiflorum, Patrinia scabiosaefolia were plant height, wherase covering rate was not good . For the expected number of seedings more than 3,000 per square meter, many seedings got withered to death while the survivors were suppressed to grow slow in the early stage due to the densityproblem.

This study aims to classify the plant communities of the Gudam wetland, a riparian wetland in Nakdong River basin, and to identify the characteristics of the communities according to the veritical structure to prepare management plan. In the Gudam wetland, a total of 19 plant communities were found through physiognomical vegetation, and were analyzed by dividing into tree dominant community, shrub dominant community, and herbaceous dominant community according to the vertical structure. When examining the results of the community characteristics analysis, the species diversity index was the highest in the tree dominant communities but there was concern about a decrease in species diversity due to the influx of exotic plants such as Sicyos angulatus. The shrub dominant community tended to have a biased species diversity index on shrub plants. The herbaceous dominant communities ware divided into wetland herbaceous communities and dryland herbaceous communities according to the species diversity index, and measures were needed to reduce the species diversity index due to artificial disturbances. The importance value was the highest in the arboreal Salix genus in the tree dominant communities, and the exotic plants such as Amorpha fruticosa were the highest in the shrub dominant communities. In the herbaceous dominant communities, wetland herbaceous plants such as Phragmites japonicus were high. As a result of the analysis according to ordination the tree dominant communities and shrub dominant communities were differentiated by exotic plant factors, and the herbaceous dominant communities were differentiated by hierarchy number and slope.

Previous studies on the host plant range of Metcalfa pruinosa were conducted without distinguishing between its stages of development. In this study, we investigated host plants by studying the nymph and adult development stages of M. pruinosa. M. pruinosa nymphs were found on host plants that belong to 78 families and 227 species, and, to the best of our knowledge, host plants that belong to 27 families and 38 species have been reported for the first time. The host plants were divided into woody and herbaceous at the nymph stage of M. pruinosa, and the nymphs were found in 110 herbaceous and 117 woody species. M. pruinosa adults were found on host plants that belong to 87 families and 233 species, and, host plants that belong to 26 families and 36 species have been reported for the first time. The host plants were divided into woody and herbaceous at the adult stage of M. pruinosa, and the adults were found in 105 herbaceous and 128 woody species. Therefore, the total domestic host plant of M. pruinosa was 98 families 345 species. The nymph and adult in preoviposition stage prefer Helianthus annuus and the adult in oviposition stage prefer Persicaria tinctoria and Rosa rugosa.
