This paper was conducted to acquire the scientific data for the waste landfill greening. The native plant flora was investigated in waste landfill at Nanjido. As a result, total 40 species, 22 families, 32 genus were classified. The dominant species were Robinia pseudoacacia (15%), Populus euramericana (3%), and Populus monilifera (1%), ect. Naive plant of 6 species (Zoysia japonica, Aster koraiensis, Liriope platyphylla, Hemerocallis fulva, Sedum kantschaticum, Indigofera pseudotinctoria) were planted in waste landfill in one species per 1 $m^2$ for greening purpose. After One year planting, the ornamental optimum value was showed in Zoysia japonica, Aster koraiensis, Hemerocallis fulva, Hemerocallis fulva, Sedum kantschaticum. The covering rate after nine months planting was 85% and 80% for Zoysia japonica and Hemerocallis fulva, respectively. While Aster koraiensis(a) 13 %, Liriope platyphylla 8 % and Sedum kantschaticum appeared 22 % were obtained. Aster koraiensis (a) has highest height and Sedum kantschaticum was the shortest plant.

This study was carried out to obtain basic envirinmental information of the native area and growth characteristics at different age of Dendropanax morbifera LEV. In the southern Korea. The Dendropanax morbifera LEV. Was grown naturally at Wando, Cheju(Mt. Halla), Yecheon(Kermoon island),Sinan(Hong isand), Jindo(Mt. Chermchill) and Haenam(Mt. Taeroon), all between 30 to 450m above the sea level. The soil characterisitics of the native area had a pH of 5.3 to 5.4 with 8.4 to 9.8% content of organic matter and 18.2 to 21.3% soil moisture. Flowering starting in the middle of July begun when the trees were 6 years old. Six year old trees are 129 cm in stem height, 34 mm in stem diameter,15.4 in number of leaves with petioles 12.9 cm long. Xylem sap can be obtained from over 10 year old trees that grew well and have over 10 cm stems in diameter.

To investigate how the dyad symmetry region (DSR) and the distance between vir box and -35 sequence of the virE promoter plays a role in virE gene expression, two mutants were constructed by base substitution and insertional mutagenesis. The base substitutional mutation, a AAlongrightarrowCG substitution at positions -39 and -40 on the DSR, showed the level of $\beta$-galactosidase activity approximately 91% of the wild type virE promoter activity. Therefore, the native structure of the DSR seems to be not essential for virE expression. The insertional mutation, constructed by inserting 8 bp ClaI linker between -49 and -50, displayed the $\beta$-galactosidase activity at 12% of the native virE promoter activity. However, this striking reduction appears to be not caused by destruction of the native DSR structure, but by shifting the vir box far from putative -35 sequence.

This experiment was conducted to study on application of several Korean native plants by seed spray methods for cut slope revegetation, and possibility of replacement almost imported tall fescue seeds by native herbaceous plants. So, we investigated growth and covering rate after sowing native plants seeds at the artificial slope plots in Suwon and the rock exposed cut-slopes in Wonju city. Emergence rate after seed spray at artificial slopes were higher Elsholtzia splendens and Dianthus superbus var. longicalycinus, showing the highest in E. splendens. Also, E. splendens, D. superbus var. longicalycinus, and Agrostemma coronaria were possible to use for seed spray at the rock exposed cut-slopes. The plots of mixed native plants show more seasonal scenery than that of tall fescue. Soil surface run-off by Typhoon was less in plot sown native plants than those of lawn grass, resulting fresh weight of roots was heavier. Thus, we found that the mixed seed spray of several native herbaceous plants, E. splendens, D. superbus var. longicalycinus, and Agrostemma coronaria, were well covered the slopes as tall fescue.

Control effect of grafting with rootstocks on Phythophthora blight of pepper was evaluated. The 40∼45 day old seedlings of five pepper cultivars, Wangdaeback, Jinmi, Boosa, Samsungcho and Pochunngchun, as a scion were grafted with ten species of root stocks. There wasn't graft incompatibility in all scion-root stock combinations. After 21 days from inoculation with Phytopkhora capsici, incidence of Phythophthora blight of plant grafted with Kataguruma, R-Safe, R-16, YCM 334 and SCM 334 of rootstocks tested was decreased by 64.6∼100％ compared to non-grafted plant whose disease severity was 3.7. However, plant grafted with Umsung native and Yeongdong native pepper was more sensitive to Phythophthora blight than non-grafed plant. Control effect by grafting was inversely proportional to virulence of inoculum and not significantly different among scion cultivars used. And resistant reaction of scion against Phytophthora blight was not affect that of scion-root stock plant in this study.

Background: The recent, decline in Black-berry Magnolia Vine (Schisandra repanda; BMV) native to Jeju Island, Korea, has raised concerns about the causes of this decline. We investigated the native environment of S. repanda and evaluated its propagation through cuttings to provide preliminary data for its restoration in Jeju Island. Methods and Results: The native environment of the BMV in the Hallasan National Park was surveyed and the climatic variables (temperature and humidity) were analyzed. The effects of the sex of the donor plant (male/female) type of cutting (softwood/hardwood), and treatment with a plant growth regulator (indole-3-butylic acid/rootone) on the rooting of BMV were investigated. Additinallly, the rooting rate, root count, and root length, as well as temperature and humidity were measured in the vinyl moist chambers. BMV was observed in 63 plants distributed from 567 m to 1,364 m above sea level of the Hallasan National Park. In the cutting experiment, the rooting rate was 71.9%, and it was higer in female plants (75.0%) than in male plants (68.8%). Conclusions: The mass propagation of BMV through cuttings valuable for its restoration as without such safeguard measures, the population could face extinction within a few decades.

This study was carried out to find heavy metal contents in soil and in native plant in the regions near by zinc-mines, located at the Chilgok and Uljin Gun in Kyeongpook area. In the heavy metal contents during the to growth of native plants, Cd was contained in the order perennial > biennial > annual plant, but Cu was annual > perennial > biennial plant, and there was no difference in Zn contents. The native plants contained heavy metal highest were Osmunda japonica in Cd, Persicaria thunbergii H.G in Cu and Equisetum arvense L. in Zn. Cd was contained highest in Pteridaceae, Cu in Equisetaceae and Zn in Polygonaceae. In the heavy metal contents by the part of plant of Equisetum arvense L. and Erigeron canadensis, Cd and Zn were much contained in the order leaf > stem > root, but Cu was in the order root > leaf > stem. The average contents of Cd, Cu, Zn in soil were 1.27ppm. 12.04ppm. 64.28ppm in Chilgok, and 3.30ppm. 72.93ppm. 194.04ppm in Uljin respectively. There were positive correlations between Cd contents of heavy metals(Cd, Cu, Zn) in soil and in native plant, but not significant. It was estimated that Osmunda japonica, Pteridium aquilinum (KUHN) var and Equisetum arvense L. which most absorbed heavy metal have effect of exclusion of heavy metals near by zine-mines region.

This study was conducted to investigate the characteristics of seed germination pattern by the prechilling and alternating temperature treatments to 16 species of native plant. The seed length, width and thickness ranged from 1.1 to 8.9 mm, from 0.7 to 7.5 mm and from 0.4 to 1.7 mm, respectively. In addition, the 1,000 grain weight of native plants ranged from 0.1 to 8.8g. Germination rate of Melandryum firmum R. and Saussurea pulchella F. with light condition, Capsella bursa-pastoris L. and Leonurus sibiricus L. with dark conditionin of non-treatment were the highest 69, 81,16 and 36%, respectively. Germination rate of Aster scaber T., Cirsium setidens N., Ligularia fischeri T., Plantago asiatica L., and Saussurea sp. of 5$^{\circ}C$ prechilling for 30 days were the highest 84, 29, 29, 57, 78 and 95% with light condition respectively, 30% but Cirsium nipponicum M. only with dark condition. Germination rate of Aralia elata S., Aster koraiensis N. and Synurus deltoides N. of alternating temperature with 8 hours at 3$0^{\circ}C$ and 16 hours at 15$^{\circ}C$ were the highest 2 and 57% with light condition and 52% with dark condition.

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.

This study was carried out to investigate the ecological characteristic of native Parasenecio firmus population in Korea and China. The survey quadrates were located in the middle of the native P. firmus habitats. According to the field survey, the habitats of P. firmus were classified into same Tilia amurensis community in tree layer. The investigation of native habitat in Korea shows that P. firmus inhabited deciduous forest from with T. amurensis, Acer pictum subsp. mono, Carpinus cordata and Acer pseudosieboldianum, which was similar to vegetation structure of Mt. Laoling in China. The result of the cluster analysis which uses SYN-TAX 2000 program, dissimilarity from 53% level was on a large scale divided at 2 units. The research revealed 96 taxa in total, in which 51 families, 81 genera, 21 varieties, 5 forma, 1 sub-species and 67 species were checked in the flora of the native P. firmus habitats.
