  • This experiment was carried out to find out proper pot size and bottom irrigation interval for the flowerpot cultivation of Cyrtomium falcatum, 3 different pot sizes (5, 7, 10cm in diameter) and 3 irrigation interval (1 day, 3 days, 5 days) were treated by completely randomized design with 3 replications. Growth characteristics of Cyrtomium falcatum were investigated every 30 days after planting. The pot size of 7 to 10cm in diameter and the irrigation interval of 5 days appeared to be appropriate for Cyrtomium falcatum cultivation.

  • The gametophytes of Cyrtomium falcatum and Cyrtomium caryoptideum var. coreanum arising from spores were mechanically homogenized and cultured In vitro, to study their gametophyte ontogeny and sporophyte development. Homogenized gametophytic tissues formed as one-dimensional filaments after 2 weeks in culture and then glowed into blanched gamatophytes after 4 weeks. After 6 weeks, which were developed to two dimensional plates with apical notch and meristem in central zone. After 8 weeks in culture, apomictic buds were formed on the midribs without archegonium formation and these buds developed to sporophytes after 10 weeks in culture. Flow cytometric analysis of gametophytes and apomictic sporophytes revealed that both forms had the same ploidy level in C. falcatum and C. caryoptideum vu. coreanum, respectively. This is to certify that C. caryoptideum var. coreanum was an apomictic fern as well as C. falcatum.

  • This study was aimed to promote evergreen ferns native to Korea as a material for interior landscape by investigate effects of light quality on the growth of Cyrtomium falcatum and Rumohra aristata, in an indoor environment that artificial light was used, especially. Result of experiments are as follows; 1. Wavelengths were measured as control(=570~580nm), red(=600~610nm), yellow(=550~580nm), green(=500~510nm) and blue(=430~440nm) between different color film. The order of photon flux density was red>yellow>control>green>blue decreased. 2. Although there was no difference in the growth of Cyrtomium falcatum depending on light quality, in case of fronds with sori and new fronds, there were highest under red film. Fresh weight was no significant in all treatments, but dry weight was increased with green>control>yellow>blue>red in order. 3. In case of Rumohra aristata, there was no difference in its growth, however, number of total fronds was highest under green film. Although fresh weight was increased with yellow film, dry weight was highest under green film.

Effects of Culture Soil Combinations on Growth of Pteris multifida, Cyrtomium falcatum and Cheilanthes argentea (인공 배양토 종류가 봉의꼬리, 도깨비고비, 부싯깃고사리의 생육에 미치는 영향)

  • The effects of culture soil combinations on growth of native pteridophyte (Pteris multifida, Cyrtomium falcatum and Cheilanthes argentea) were investigated in this study. Six different culture soil mixtures used for cultivating the pteridophytes under 30% shading condition. Pteris multifida was showed the most growth at the culture soil mixtures of peatmoss : living moss (5 : 5), and peatmoss : perlite (7 : 3). Cyrtomium falcatum and Cheilanthes argentea showed the best growth in the culture soils mixtures of sand : soil : leaf mold (2 : 5 : 3) and peatmoss : perlite (7 : 3, 5 : 5), respectively.

  • Macromyzus woodwardiae(Takahashi, 1921) is recognized on Cyrdomium falcatum(L.f.) C. Presl (Dryopteridaceae), a htherto unknown host plant, from Jeju Island, Korea. Apterous viviparous female and alate viviparous female are described. This is the first record of genus Macromyzus in Korea.

  • This study was performed to determine the effect of nutritional concentrations and fertilization intervals on growth of native pteridophyte (Pteris multifida, Cyrtomium falcatum, Cheilanthes argentea). Nutrient concentrations were treated with non-treat, 500X, 1,000X and 2,000X solution, and fertilization periods were treated in everyday, 5, 10 and 20day respectively, under the 30% shading net. Pteris multfida appeared to be very good for growth by fertilizing at intervals of 10 day with nutrient concentration of 2,000X drainage solution. The growth of Cyrtomium falcatum was the best in the treatment of $1,000{\sim}2,000X$ concentration for 10 days while that of Cheilanthes argentea was the highest in the treatment of 1,000X concentration for 5days.

  • In the present study, the halophyte C. falcatum extract and its solvent fractions (n-hexane, 85% aqueous methanol, n-butanol, and water) were evaluated for antioxidant and anti-inflammatory activities. Antioxidative ability was measured by DPPH radical, intracellular reactive oxygen species (ROS) and peroxynitrite scavenging, DNA oxidation inhibition, and ferric reducing antioxidant power (FRAP). For DPPH radical and peroxynitrite scavenging, DNA oxidation inhibition, and FRAP, 85% aq.MeOH and n-BuOH fractions showed significant scavenging activity. For production of intracellular ROS in HT-1080 cells, 85% aq.MeOH fraction showed the highest scavenging activity. In addition, anti-inflammatory activity was also assessed by measuring the inhibitory effect against mRNA expression of pro-inflammatory factors (NO, IL-1β, IL-6 and COX-2) in LPS-stimulated Raw 264.7 macrophages. For NO production, crude extract exhibited a strong inhibitory effect at a concentration of 100 ㎍/ml. For mRNA expression of pro-inflammatory cytokines (IL-1β, IL-6, and COX-2), n-BuOH greatly suppressed expression levels of IL-1β and IL-6 at 100 ㎍/ml concentration while 85% aq. MeOH fraction significantly inhibited that of COX-2 even at 100 ㎍/ml. These results suggest that C. falcatum may be used as a potential source for the development of a natural antioxidant or anti-inflammatory agent.
