This study was carried out to investigate the flora of Mt. Biseul. The vascular plants collected 10 times(from May 2006 to October 2007) were identified as 468 taxa in total, including 89 families, 302 genera, 397 species, 1 subspecies, 59 varieties and 11 forms. Korean endemic plants of this area were identified as 17 taxa including Thalictrum uchiyamai, Coreanomecon hylomeconoides, Lonicera subsessilis, etc.; the Ministry of Environment-designated plants, which should be protected by the wildlife protection law, were identified as one taxon including Aconitum austrokoreense; the Office of Forestry-designated rare & endangered plants were identified as 6 taxa including Viola albida, Lloydia triflora, Streptopus ovalis, etc.; the naturalized plants were identified as 34 taxa, and their naturalization ratio and urban index were found to be 7.3%, and 12.2% respectively. This study newly identified about 160 taxa of the plants, among which 17 taxa were newly added to the list of naturalized plants, such as Phytolacca americana, Dicentra spectabilis, Lepidium apetalum, Medicago lupulina, Euphorbia supina, Ambrosia artemisiifolia, Cosmos bipinnatus, Crassocephalum crepidioides, Galinsoga ciliata, Rudbeckia bicolor, Sonchus oleraceus, Tagetes minuta, Taraxacum officinale, Chloris virgata, Festuca arundinacea, Lolium perenne, Tradescantia reflexa, etc. There existed many kinds of plants resources having conservational value like Aconitum austrokoreense etc. in this area, but there remains a fear of nature destruction's acceleration due to indiscriminate human development and access of a lot of visitors, so it is judged that there should be a management plan, such as a limit on the number of visitors or rest-year-system for restoration of nature.

A standard rose cultivar, 'To Dios'(Rosa hybrida) was selected for use as a cut flower from the progeny of a cross between 'Vanilla perfume' and 'Marcia' at the research and development division of the Goyang-si Agricultural Technology Center in 2013. 'Vanilla perfume', an orange-colored (RHS Orange Group 27C) standard rose cultivar with 48 petals, was used as the female plant. 'Marcia', a white-colored (RHS Green white Group 157B) standard rose cultivar with 96 petals was used as the male parent. A cross was made in 2009 and seedlings were produced. Selections were made between 2010 and 2013, and a plant with good cut flower traits was finally selected and named 'To Dios'. 'To Dios' is a standard rose with large flowers of 11.2 cm in diameter and 128 peach-colored (RHS Red Group 36B) petals per flower. Vase life of this cultivar is up to 15 days. It takes 47 days from pruning to blooming and cut flower productivity is approximately $160stems/m^2$ per year. 'To Dios' was registered as a new cultivar No. 4875 with the Korea Seed & Variety Service on March 19, 2014.

The effect of various fungicides on anthracnose of strawberry, caused by Colletotrichum gloeosporioides, was determined in vitro, and in greenhouse and field trials. The $EC_{50}$ values of benomyl were clearly different between two sensitive and resistant groups of isolates. Iminoctadine tris had lower $EC_{50}$ values than mancozeb and propineb as protective fungicides and the response of mancozeb, propineb and azoxystrobin was variable depending on the isolate. In the greenhouse, pre- and post- inoculation fungicide applications significantly reduced disease compared to the non-treated control. Propineb, mancozeb and azoxystrobin were effective in controlling the disease when applied prior to inoculation. Metconazole and prochloraz-Mn treatments as ergosterol biosynthesis-inhibiting fungicides had the lowest incidence of anthracnose. In the nursery field trials in 2009 and 2010, the reduced fungicide spray program provided similar levels of disease control compared to the calendar-based applications with captan. A reduced spray program based on efficacious fungicides such as prochloraz-Mn will be useful for strawberry growers and provide more options for controlling anthracnose in Korea.

Mugwort (Artemisia sp.) abounds on hedgebank, waysides and grassy places in most part of Europe, Asia and Northern America. This herb has long been associated with witch-craft and magic as a protective charm. Mugwort has been a value as a foodstuff of relieving famine. Proximate composition of mugwort is similar to green vegetables, but it has high level in calcium, potassium and vitamin A content. For medicinal uses, the leaves are harvested twice in spring and autumn before the plant comes into flower and are dried for later uses. Aqueous or organic solvents extracts often have physiologically active constituents. Some extracts of mugwort include cineol, thujone, borneol, camphor, caryophyllene, coumarin, cubebene, pinene, linalool, absinthin etc. The dried leaves have traditionally been used as an antihelmintic, anti-inflammatory, antispasmodic, antitumor, hepatic stimulant, chologogue, emmenagogue, febrifuge, stomachic, tonic etc. Mugwort has been used the dried or green leaves as a flavoring and coloring agents for tea, cake. pastry, bread, noodle, alcoholic liquor, soap and hygienic band.

This study was conducted to investigate composition of understory vegetation and indicator species by altitude and slope azimuth in Mt. Gyebang designated as Protected Area for Forest Genetic Resource Conservation and National Park. Tracheophytes were 350 taxa; 80 families, 203 genera, 303 species, 38 varieties, 5 forma and 4 sub-species in research area. The species of greatest importance value were Tripterygium regelii (9.143%), Acer pseudosieboldianum (7.594%), Symplocos chinensis for. pilosa (6.347%) in the shrub layer and were Sasa borealis (8.653%), Isodon excisus (2.936%) and Carex siderosticta (2.897%). In the herb layer as a result of NMS analysis, the distribution range of the major species were found to be affected by the altitude (shrub layer: $R^2$ > 0.3, herb layer: $R^2$ > 0.6). The result of plexus diagram analysis showed that Acer pseudosieboldianum was associated with Magnolia sieboldii, Acer barbinerve, Euonymus oxyphyllus etc. in the shrub layer; Meehania urticifolia was associated with Aconitum jaluense, Veratrum oxysepalum, Prunus padus etc. in the herb layer. The significant indicator species were analyzed for 60 species by the altitude and investigated for 30 species in accordance with the slope azimuth. As a consequence of MRPP, interspecies composition along the altitude group was heterogeneous and the species composition according to the azimuth slope was extremely different between the NE and SW.

Taxonomical studies of the genus Acer in Korea (8 species, 3 varieties and 1 forma) were studied by the morphological characteristics of stipules. The results obtained were summarized as follows; 1) The stipules of the genus Acer were arranged oppositely with 4 - 10 stipules consisting of simple leaf, compound leaf and unifoliate compound leaf. The venation of stipules were cladodromous, basal reticulate, fibrous and palmately netted vein. The trichoma of stipules were glandula hair, glandular pubescent, sericeous, pilous, vinous, velutinous, tomentose, ciliate and lanate. As the morphological characteristics of stipules in the genus Acer established a strong point in the identification of species. 2) The species in the genus Acer in Korea were classified into six groups; (1) ginnala group (A. ginnala), (2) koreanum group (A. koreanum, A. japonicum, A. pseudosieboldianum var. koreanum), (3) mono group (A. mono, A, palmatum var. sanguineum, A. palamtum var. dissectum, A. palmatum var. dissectum f. aosidare), (4) negundo group (A. negundo), (5) palmatum group (A. palmatum), (6) platanoides group (A. platanoides, A. truncatum) by the morphological characteristics of stipules, 3) The stipules of platanoides group and negundo group were the least evolved types among the species in the genus Acer. 4) The stipules in the genus Acer were made the inner buds that were metamorphosed to the protected functional aspect by the evolution of petiols.
