  • Spiraea prunifolia var. simpliciflora (Rosaceae) is a deciduous. latifoliate shrub growing in most parts of Korea. The roots of this plant have been used for malaria, as antipyretics and emetics. From the roots of this plant, sterol glycoside and two triterpenoids were isolated and the structures were elucidated by chemical and spectroscopic methods. They were identified as $3{\beta}-hydroxyurs-12-ene-28-oic$ acid (ursolic acid.1), $2{\alpha}$, $3{\beta}$, $19{\alpha}-trihy-droxyurs-12-ene-28-oic$ acid (tormentic acid.2) and ${\beta}-sitoste-rol-3-O-{\beta}-D-glucopyranoside$ (3).

  • Vegetation composition and structure of forest community at Mt. Bislsan, Dalseung-Gun, Daegu in Korea, were studied using a qualitative with a quantitative approach and its vegetation types and various ecological characteristics such as the importance values, species diversity of the major component species analyzed. The forest vegetation were classified into 2 community group, 14 community, 6 group, and total of 18 vegetation units. Pinus densiflora distributed mainly from lower at the sea level, while Quercus mongolica tended to distributed upper altitude in Physiognomical vegetation. the species diversity values showed mostly 0.8 and Quercus dentata, Quercus serrato and Cornus controversa Community and so on highly showed to 1.0 and 1.1. According to the results of importance value analysis, the I.V. of pinus densiflora and Quercus mongolica highly showed in the tree and subtree layer, and Rhododendron mucronulatum and Lindera obtusiloba and so on highly showed in the shrub.

  • Non-conventional roughage (NCR) is shrub and tree fodders, crop residues and agroindustrial oy-products which is not commonly used as livestock feed traditionally and commercially. Eventhough many sources of NCR is available, the farmers perceptions on NCR not only vary from country to country in tropical and sub-tropical Asian-Australasian countries, but also vary from region to region within the country. Chemical composition and nutritive value of NCR are not only vary from species to species but also vary between species within the genera, between provenances/cultivars within the species and such variations are affected by season, climatic zone, topography and land utilization. The nutritive value of NCR can be improved by physical, chemical and biological treatments and conservation. Feeding NCR to ruminant and non-ruminant is not only improve performance of the livestock but also economically feasible. Future direction of NCR is inventarization, exchange information through NCR information centre, integration with either agrisilvicultural, agrisilvipastoral or silvipastoral system, and use of genetic engineering to produce high quality NCR that ultimately become conventional roughage for agroindustry and agribissiness.

  • A syntaxonomical study about coastal sand dune vegetation in Kyungpook province was carried out. This study was accomplished by the methods of classical block-structure seeking and had-sorting of the $Z\"{u}rich-Montpellier$ School. The main purpose of this study is to clarify the syntaxonomical, synecological, syngeographical and syndynamical characteristics of coastal sand dune vegetation in Kyungpook province. The dune shrubs communities in Kyungpook province are consisted of 2 communities: Vitex rotundifolia community of southern type and Rosa rugosa community of northern type. And the dune grasslands communities are also consisted of 2 communities: Elymo-Caricetum kobomugi Ohba, miyawaki et $T\"{u}xen$ 1973 and carex kobomugi typical community. The subsidiary knowledges from this study will make possible to accumulate qualitative and quantitative information in the distribution pattern of coastal sand dune vegetation, and also will provide practical information for national biodiversity and conservation of coastal ecosystem.ecosystem.

  • The floristic composition of the Korean-fir(Abies koreana Wilson) forest on Mt. Halla in Cheju Island, Korea, was described and some other phytosociological features were noted. The dense tree layer of the Abies koreana forest under consideration attained a height of no more than 5-7m. The shrub layer was 1.2-2m high and usually inconspicuous, while the herb layer, 0.3-0.5m high, was remarkable. The forest contained a number of species which are characteristic of the subalopine coniferous in Japan, particularly that in Hokkaido. Moreover, the specific synchronized regeneration called wave-regeneration was found in the forest on Mt. Halla at several sites even though the data on this phenomenon do not present in the present report.

  • Wood-anatomical studies on vines, one of the main materials for fork craftworks used in the past, were insufficient compared to those for trees. Therefore, it is important to identify the species of vines in order to preserve the vinery craftwork relics. In this study, the species of 31 samples (30 traditional baskets and one sculpture relic) obtained from Korea were identified. Twenty-two baskets among 30 baskets were identified as Cocculus trilobus DC, a perennial vine which has flexible xylem and thick fibers in phloem. The other baskets were identified as $Lespedeza$ spp., a shrub with tough xylem. The sculpture part was $Actinidia$ $arguta$ Planch., a perennial vine with chambered piths.

  • The fungistatic effects of extract and crystal (A) of Berberis Koreans Palibin, a common shrub in Korea, were obeserved and compared with undecylenic acid and vegetable oil. In vitro studies, the spores of fungi were inoculated on Sabouraud's glucose agar media which contained compounds of various concentration, and the growth of the fungi was observed for 3 weeks. The species of the fungi used in these experiments were Epidermophyton floccosum, Microsporum gypseum, Microsporum audouini, Microsporum canis, Microsporum nanum, Microsporum cookei, Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton tonsurans and Trichophyton verrucosum. The results of the studies were as follows: 1. The growth of E. floccosum, M. audouni, M. canis, M. nanum, M. cookei, was inhibited in Sabouraud's glucose agar media containing extract and crystal (A) of Berberis Koreana Palibin 1 mg/ml.

  • The alpine grassland vegetation at the northwest slope of Mt. Paektu were investigated by Penound- Howard's cover-degree method. The floristic composition of the alpine grassland from 2,100m altitude to the top of mountain were 35 species, 1 subspecies, and 6 varieties, and most of the plants were short p e r e ~ i a l herbs and shrubs. The dominant species of the vegetation distributed along to altitude were Rhododendron aureum (2,100-2,20Om), Dryas octopetala var. asiatica(2,200-2,30Om), Dryas octopetala var. asiatica(2,300-2,40Om), Rhododendron aureum- Rhododendron redowskianum(2,400-2,50Om), and Rhododendron redowskianum(2,500- 2,58Om), respectively. Characteristics of the shrub plants which settled in alpine grassland showed uniform low height(3-15cm), creeping stem and evergreen leaf. Life form of the plants were 29 species of Hemicryptophyte, 8 species of Chamaephyte, 1 species of Geophyte, and 5 species of Phanerophyte. (Key words : Alpine grassland, Mt.

  • The floristic composition and structure of the Oriental Arbor-viate forest, natural monument no. 1, were investigated in the Daegu city, southeastern Korea. Vegetation stratification have four layers including tree (>5m), subtree (2m-5m), shrub (1m-2m) and herbs (<1m), which occupied 63.8%, 10.7%, 12.1% and 49.4%, respectively. The vegetation of the study area were divided into Artemisia keiskeana - Quercus variabilis and Pyrrosia linearifolia-Thuja orientalis (OAV) communities. Frequency distribution for diameter classes of the Oriental Arbor-vitae population showed a reverse-J shape. The result suggests that the OAV forest of this site might maintains continuously the present state. The annual radial growth of OAV, Pinus densiflora and Quercus variabilis, the dominant species of the present site showed 0.29, 1.01 and 1.28 mm/year, respectively. Competition of OAV with theh other species including P. densiflora and Q. variabilis could influence negatively on the growthand survival of OAV forest in this site.
