  • Description of spore morphology of Korean Polypodiaceae has on LM and SEM and key to the genera are provided. Korean Polypodiaceae monad, monolete with bilateral symmetry, bipolar and oblete spore except for Loxogramme grammitoides having trilete spore with radial symmetry. In spore wall structure, exopore showed variable patterns enough to distinguish genera. Perispore was found in all the species examined. The patternof perispore and exospore was most similar in all the species examined except Crypsinus, Pyrrosia hastata ans P. linearifolia. The perispores of Crypsinus, Pyrrosia hastata and P. linearifolia were echinate and gemmate, rugulate, and verrucate respectively. In term of exospore wall sculpturing, Polypodium and Loxogramme showed fossulate, Lepisorus, rugulate with irregular verrucate, Crypsinus ans Coloysis showed psilate or rarely verrucate in the latter, Neocheiropteris ensata showed dense small verrucate, Lemmaphyllum microphyllum showed complex reticulate and Pyrrosia showed verrucate or psilate.

  • The Late Quaternary palynoflora from an archaeological site in Piseo-ri, Muan, Korea consists predominately of deciduous broadleaved angiosperms and subordinately of herbs and conifers. Dominant taxa are Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, Alnus, Carpinus, deciduous Quercus, Compositae and Gramineae. The palynoflora dated 43,000-18,000 yr BP, corresponding to the last glacial period, is similar to the modern vegetation of the cool temperate deciduous broadleaved forest in the middle part of the Korean Peninsula. Based on palynofloral composition, three palynozones are recognized. Zone I represents a cool temperate deciduous broadleaved forest, composed of Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, Alnus and D. Quercus, and is characterized by persistent occurrence of warm temperate taxa. Zone II shows drastic decrease in Polypodiaceae, Taxodiaceae-Cupressaceae-Taxaceae, and increase in herbs. This zone reflects a cool temperate deciduous broadleaved forest with scattered open grasslands. Zone III is characterized by dominance in herbs and increase in conifers. The palynofloral composition suggests a cool temperate climate, and variation in occurrences of main taxa indicates that climatic conditions gradually became cold and dry.

  • Biorenovation is a method for converting materials using the enzyme properties of microorganisms. Natural products converted by that method increase physiological activity or reduce cytotoxicity. In this study, we investigated the anti-inflammatory activity of crypsinus hastatus prothallium (CH) and biorenovated CH prothallium (CHB) using RAW 264.7 cells stimulated with lipopolysaccharide (LPS). CHB inhibited the production of nitric oxide, prostaglandin E2 and cytokines (interleukin-6, interleukin-1β, tumor necrosis factor-α) compared to CH at a concentration of 50-200 ㎍/mL. In addition, CHB concentration of 200 ㎍/mL inhibited the expression of inducible nitric oxide synthase and cyclooxygenase-2 protein by LPS stimulation to the level of the untreated control group. These results indicate that CHB could be a novel anti-inflammatory agent for cosmetic and pharmaceutical ingredients.It also suggests that the application of biorenovation has potential usefulness in developing anti-inflammatory materials. It also suggests that the application of bio-renovation has potential usefulness in the development of inflammatory material. We applied Biorenovation technology to Distylium racemosum extract (DR) to generate Distylium racemosum biorenovation product (DRB), and investigated the anti-inflammatory properties of DRB in lipopolysaccharide (LPS)-treated RAW264.7 macrophages. We are applying technology to Biorenovation Distylium racemosum extract (DR) Distylium racemosum was to create a biorenovation product (DRB), lipopolysaccharide (LPS) investigated the anti-inflammatory properties of DRB in RAW264.7 macrophages treated for.

  • This study was carried out as basic data for the conservation and management of plant diversity in the Gudeuljang paddy fields stone retaining wall of Cheongsan-island by identifying the characteristics of vascular plants targeting Gudeuljang paddy fields stone retaining wall in Cheongsan-island. The total vascular plants of the Gudeuljang paddy fields stone retaining wall in Cheongsan-island have been identified with a total of 184 taxa of 60 families, 142 genera, 170 species, 5 subspecies, 9 varieties. Rare plants were 1 taxa, Korea endemic plants were 2 taxa, floristic regional indicator plants were 28 taxa, rock vegetation was 20 taxa, and invasive alien plants were 25 taxa. Among them, Selliguea hastata (Thunb.) Fraser-Jenk., a rare plants, has been identified as a small number of individuals in the Gudeuljang paddy fields stone retaining wall in Buheung-ri and Cheonggye-ri, but it is necessary to conservation the habitat because there is a concern that the species and population will decrease due to damage and neglect of the Gudeuljang paddy fields stone retaining wall.

  • Background : This text was conducted to evaluate the distribution, shape characteristics and habitat condition of Crypsinus hastatus in Buyeo Korea. Methods and Results : In Buyeo, Crypsinus hastatus was distributed at an altitude of 31.2 m, a slope of 82.5% and a distance from river water of 27.2 m. The leaf blade was oblong, 2.7 cm long, 1.2 cm wide with a petiole length of 2.3 cm. The total population comprised 2,100 individuals, with the highest proportion being individuals with a leaf blade of length 0.5 - 1 cm. The temperature and light intensity of the growth point were lower, but the humidity higher, than that of growth around. The chemical properties of the soil were as follows: pH 4.42, organic matter 77.99 g/kg, electrical conductivity 0.50 dS/m, nitrate nitrogen 20.50 mg/kg and available phosphate 165.7 mg/kg. Exchangeable cation content of potassium, magnesium, sodium and calcium was 0.35, 0.70, 0.09 and $2.04cmol^+/kg$, respectively. Conclusions : In Buyeo, Crypsinus hastatus was distributed in $5.3m^2$ area of Nakhwaam, Naeseongri and Jeongamri. However, the population of the medicinal resources seemed to decrease owing to the poor environmental conditions of the habitat.

  • The vegetations of Hansan and Chubong islets in Tongyoungsi were investigated from April, 1997 to December, 1998 and a synthesis table was constructed. Based on the synthesis table, the vegetation was classfied into 6 communties: Pinus thunbergii community, Pinus densiflora community, Machilus thunbergii community, Chamaecyparis obtusa afforestation, Cryptomeria japonica afforestation, Miscanthus sinensis var. purpurascens community, and 3 subcommunities: Pinus thunbergii typical subcommunity, Quercus variabilis subcommunity, Carpinus coreana subcommunity. The vegetation of Pinus densiflora community around Jeseungdang area is well preserved. However the islet requirs the ecological restoration, and we suggest that the rare species such a Crypsinus hastatus, old trees of Machilus thunbergii and Pinus thunbergii, and the habitat for Machilus thunbergii and Camellia japonica must be preserved.
