  • This study was aimed at searching for the wintering Cd hyperaccumulators as the life cycle of existing hyperaccumulators were mostly from spring to early winter season. The wintering hyperaccumulators can be effective for saving time loss during the winter. A pot experiment was conducted to search for hyperaccumulators through out the native wintering plants. Seven species of native wintering plants were applied; Bromus catharticus, Oxatis corniculata, Festuca rubra, Thlaspi. arvense, Agastache rrgosa, Viola seoulensis, and Patrinia rapestris. Among them, Bromus catharticus and Thlaspi arvense were selected as Cd hyperaccumulators; the two plants accumulated 112.35 and $86.69mg\;kg^{-1}$ of Cd in the shoot, respectively.

  • This study was conducted to investigate the effects of foliar endophytic fungi and arbuscular mycorrhizal fungi (AMF) on plant community structure in experimental microcosms containing an assemblage of five species of plants (Oenothera odorata, Plantago asiatica, Trifolium repens, Isodon japonicas and Aster yomena). Leaves of Sasa borealis, Potentilia fragarioides, and Viola mandshurica were collected in Chungbuk, Korea. Endophytic fungi were isolated from the surface sterilized leaves and identified to species level using molecular and morphological techniques. Four isolates of the endophytic fungi were inoculated to the leaves of host plants in the microcosms. Also, three species of AMF spores were extracted from pure cultures and the mixture of the three species inoculated to the roots of the plants. After four months of growth in a green house, effects of both symbiotic fungi on plant species diversity, community composition and productivity were examined. The plant species diversity showed significant differences with inoculation of the symbiotic fungi. Results indicate that AMF significantly affect plant productivity and plant community structure.

  • The vascular plants in the Ohseosan and the Bongsusan, Chungnam were listed 439 taxa (9.0% of all 4,881 taxa of vascular plants); 95 families, 268 genera, 339 species, 5 subspecies, 75 varieties and 20 forms. Furthermore, the Ohseosan were listed 339 taxa and the Bongsusan were listed 306 taxa. So, Hemicryptophytes (H) were 107 taxa (24.4%), Therophytes (Th), Geophytes (G) same as were 82 taxa (18.7%) showed high proportional ratio in life form. Based on the list of rare plants, 4 taxa; Aristolochia contorta, Viola albida, Scutellaria insignis (LC) and Scrophularia koraiensis (DD) and endemic plants, 8 taxa; Aconitum pseudolaeve, Ajuga spectabilis, etc. Based on the list of specific plants, 35 taxa; Wisteria floribunda for. floribunda in class IV, 5 taxa (Scutellaria insignis, Scrophularia koraiensis, etc.) in class III, 5 taxa (Acer triflorum, Cymopterus melanotilingia, etc.) in class II, 24 taxa (Pyrus ussuriensis var. ussuriensis, Campanula punctata, etc.) in class I. Based on the list of naturalized plants, 9 families, 20 genera, 24 taxa (Persicaria orientalis, Carduus crispus, etc.) and ecosystem disturbing plants were Rumex acetocella, Ambrosia artemisiifolia. Naturalization rate was 5.5% of all 439 taxa of vascular plants and urbanization index was 7.5% of all 321 taxa of naturalized plants. In particular, for rare plants, in and ex-situ conservation of genetic resources must surely be done, by preserving present natural habitats, discovering additional natural habitats and securing seeds. Moreover, ecosystem disturbing plants require long-term monitoring and consistent management, since not only do they disturb the ecosystem in competition with Korean native species, but damage humans, too.
