A total of 750 kinds of vascular plant(49 orders, 122 families, 434 genera, 627 species, 1 subspecies, 111 varieties and 11 forma)were observed in Mt. Ioghe. The newly observed plant species were Dioscorea quingueloba, Spiranthes sinensis, Cephalanthera falcata, Angelica gigas, Clematis patents, Paeonia obovata, Hibiscus mulabilis, Ainsliaea acerifolia, Dictamnus dasycarpus, Cynachum ascyrifolia, Vaccinium koreanum, Erythrortium japonicum, Indigofera kirilowii (17species), Broussonetia kazinoki var, humillis, Euonymus, fortunei var. radicans, Juniperus communis var, nippnnica, Callicarpa japonica var. radicans, Joniperus communis var. rzipponica, Callicarpa japonica var. taquetii (4 varieties) and L indera obtusiloba for. billosum (1 forma). 2. The life spectrum of flora in Mt. Joghe was classified into $CH-D_1-R_5-e$ type. Distribution area was identical to Southern type by Nakai, Lee, and Yim. A few subtropical species were also observed. 3. Simpson's species diversity index(Ds) was 0.9 and Shannon-Weiner's diversity index (H') was 1.004. These indice suggest that the vegetation in Mt. Joghe is of complicated forest communities. 4. Pte-Q was 1.81 which was higher than the nationwide mean of 1.68. Urbanization Index (UI) was 28.75 for naturalized plant species, and 17.49 for exotic woody plant species, which were similar to those of Mt. Baekun and Mt. Naejang. 5. The forest vegetation of Mt. Joghe was grouped in 3 vegetation types : 7 natural plant Communities dominated by Quercus serrat, Quercus acutissima, Quercus variabilis, Carpinus laxiflora, Pinus derasiflora and Platycarya strobilacea, 8 substitutional plant communities Styrax japonica, Stewartia koreana, Lindera erytlrrocarpa, Zelkova serrata, Rhtrs chinensis, Controversa, and Frzrxirtus manrlshurica, and 7 plantation Communities composed of Pinus koraiensis, Pinus rigida, Magnolia nbnvata, Chamecyparis obkrsa, Larie ieptolepis, Castanea crenata and Cryptomeria japonica. 6. Actual vegetation maps and profile diagrams were made by phytosocialogical classification. 7. As the important and unique species in Mt. Joghe, Lindera sericea, Penicaria tilitorme, Hex macropoda, Hex macropoda for. pseudo-macropoda, Steroartia koreana, Adenopkora palustris and Corylop.,is coreana, which were also seported by Lee(1977), Kim and Yark(1989), were identified and Vaccinium coreanum, Cremastra appendiculinium, Juniperus comminis van. nipponica, Cephalanthera falcata, Broussortetia kazinoki var. humilis, paeonia obovata, Deutzia prunifolia, Dictamnus dasyarpus, Angelica gigics and Bupleurum falcatum were odditionally observed.

The vegetation of Mt. Joghesan of a provincial park in Cheolanamdo was surveyed over twenty times from July, 1980 to December, 1981. The plants of Mt. Jonghesan consisted of 10 forma, 107 varieties, 597 species, 424 genera and 122 families, and among them were 204 species of esculent plants, 199 species of medicina plants and 30 species of the others oil plants and fiber plants. Evergreen herbs consisted of 12 species, including Coniogramme intermedia, Asplenium sarelii, and Asplenium incisum etc. And Evergreen broad-leaved trees consisted of 22 species, including Thea sinensis, Sasa borealis, and Quercus acuta etc. And evergreen needle-leaved trees consisted of 15 species, including Torreya nacitora, Pinus densiflora, Sciadopitys japonica, and Chamaecyparis obtusa etc. The community of broad-leaved consisted of Quercus spp, Carpinus laxiflora, Sasa borealis, including leading dominant species of Lespedeza maximowiczii, Viburnum erosum, Fraxius rhynchophylla, Viburnum dilatum, Rhus trichocarpa, Zelkova serrata, Miscanthus sinensis, Eragrostis ferrugina, Carex augustinowiczii persicaria filiforme var. neofiliforme, Vicia amoena, Smilax riparia var. ussuriensis, and Aster yomena etc. The vegetation of Seunamsa areas in Mt. Joghesan was favorable but the vegetations of the other areas in the mountain were negligible. The vegetation of Koolmokchi areas which had been much destroyed by forest fires was mostly covered with Quercus spp which are resistant to forest fires. Lindera sericea, Alangium platanifolium var. macrophyllum, Ilex macropoda, Corylopsis coreana, Albizzia julibrssin of old trees, Acer mono, the community of Thea sinensis, Stewartca koreana, Cornus alba, Dryopteris bisstiana, Asplenium incisum, Camptosorus, Lepisorus thunbergianus, gastrodia elata, Cymbidium goeringii, and the community of Persicaria filiforme var. neofiliforme etc. in Mt. Jonhesan are autochthonous flora, and their preservation is required. As the Pinus densiflora forest in Mt. Joghesan which was hewn down by human power has not been restored, Jeopchi areas and Koolmokchi areas in Mt. Joghesan have no Pinnus densiflora trees 700m above the sea level.

This study examined the growth characteristics of broad-leaved container seedlings of Stewartia pseudocamellia, Tilia manshurica and Chionanthus retusus in relation to the raw material properties of the container medium in a green house for 4 months in order to develop optimum container medium for broad-leaved container seedlings. Among the container media used, the high level of the height growth and root collar diameter growth of broad-leaved container seedlings of Stewartia pseudocamellia, Tilia manshurica, Chionanthus retusus was found in the container media with relatively more cocopeat or peatmoss, and the dry matter production of the aerial part and the subterranean part. Also, concerning physiological characteristics, the photosynthetic rate of broad-leaved container seedlings increased in proportion to the volume of cocopeat and peatmoss in the container media. The effect of container media on the growth of broad-leaved container seedlings needs continuous study on the irrigation and fertilization programs along with the study on physiological characteristics including growth characteristics, biomass production and photosynthesis.
