The conditions for callus formation and plant regeneration were confirmed in birdsfoot trefoil (Lotus corniculatus L.). Among SH (Schenk and Hildebrandt), MS (Murashige and Skoog) and N6 medium (Chu), SH medium was highest degree of efficiencies respectively in callus formation and plant regeneration. In this study, we determined volume of hormones and other compounds appended in media. For callus formation, only $3mg/{\ell}$ of 2,4-D (2,4-dichlorophenoxy acetic acid) was appended in their media. For plant regeneration, we used BOi2Y medium (Bingham et al.). We obtained birdsfoot trefoil plants from callus by regeneration, about sixty days later transfer calli to regeneration media.

When root initiation ratio of cut Birdsfoot trefoil (Lotus corniculatus L.) stems was examined in several medium conditions containing different IBA concentration, the higher IBA contration of medium was elucidated superior then lower IBA concentration. Highest root initiation ratio was confirmed at 2.5 mg/$\ell$ of IBA and the ratio was 90~95%. When the stems from regenerated shoots from callus were treated at 8 kinds of medium for 12 days, the root iniation result was 9 (45%) at 1/2 SH-0 medium, 10 (50%) at SH-0 medium, 10 (50%) at SH-0.5IBA medium, 10 (50%) at SH-1.0IBA medium, 13 (65%) at SH-1.5IBA medium, 14 (70%) at SH-2.0IBA medium, 19 (95%) at SH-2.5IBA medium and 14 (70%) at SH-3.0IBA medium.

Six species of Glomus and one species of Acaulospora of vesicular-arbuscular (VA) mycorrhizal fungi associated with four salt-marsh plants(Calamagrotis epigeios, Lotus corniculatus, Artemisia scoparia and Imperata cylindrica were isolated from salt-marsh soil. The six species of Glomus were identified as G. albidum(lst type), G. pulvinatum(2nd type), G. constrictium(3rd type), G. sp.(4th type), G. caledonicum(5th type), and G. sp. (6th type). The one species of Acaulospora was identified as A. scrobiculata(7th type). Three mycorrhizal fungi, G. albidum(l st type), G. pulvinatum(2nd type) and G. sp. (4th type) among the 7VA fungi were the most abundant types. The most common type of VA fungi occurred in rhizosphere soil from each plant was G. sp. (4th type) for Calamagrostis epigeios and Artemesia scoparia equally and G. pulvinatum for Lotus corniculatus and Imperata cylindrica equally.

The aim of this study was to determine the nutritive value of some legume species in salt-affected soils of South-East Anatolian region using chemical composition and in vitro gas production kinetics. In this study, Lotus corniculatus, Trifolium alexandrinum, Medicago sativa were sown and tested in four different locations. A 3 by 4 factorial design with 3 legume species and 4 salt levels (non salty electrical conductivity (EC)<4 dS/m; low salt: 4 dS/m>EC<8 dS/m, medium saline: 8 dS/m>EC<16 dS/m and high salt: 16 dS/m>EC) was used in the study. Results indicated that salinity and plants had no significant effect on ash and ether extract. Dry matter (DM), acid detergent fiber, digestible dry matter, dry matter intake (DMI) were affected by plant, salinity and plant${\times}$salinity interaction. On the other hand neutral detergent fiber, relative feed value (RFV), and DMI were affected by salinity and plant${\times}$salinity interaction. Mineral contents were affected by plant species, salinity and salinity${\times}$plants interactions. In vitro gas production, their kinetics and estimated parameters such as were not affected by salinity whereas the gas production up to 48 h, organic matter digestibility, metabolizable energy (ME), and net energy lactation ($NE_L$) were affected by plant and plant${\times}$salt interaction. Generally RFVs of all species ranged from 120 to 210 and were quite satisfactory in salty conditions. Current results show that the feed value of Medicago sativa is higher compared to Lotus corniculatus and Trifolium alexandrinum.

The purpose of this study was to suggest the possibility of utilizing the wildflower pasture for promoting public interest. Growth characteristics, botanical composition, fauna distribution on wildflower pastures were observed. The experimental design included two treatments: native wildflower pasture(NWP, turf grasses 6 species + native wildflower 11 species) and introduced wildflower pasture(lWP, turf grasses 6 species + introduced wildflower 9 species). The field trials were carried out on the experimental pasture plots at Chungnam National University from 1997 to 2000. The results obtained are as follows: 1. The flowering of wildflower was maintained continuously from May to September, and the colors of wildflowers; varied seasonally during this period. With native flowers, however, Hemerocallis fulva, Belamcanda chinenis and Aster koraiensisi showed problems in lately germination and early establishment. Meanwhile, Introduced wildflower showed not only excellent germination and early establishment compared to native flowers species but also maintained brighter colors. But Coreopsis tinctoria, Achillea mi/lefolium and Rudbeckia bicolor had colonized at a higher height or possessed stronger rhizome. 2. The appropriate species of turf grass which maintained continuous seasonal distribution are thought to be tall fescue, perennial ryegrass. Kentucky bluegrass in NWP and IWP. 3. Botanical composition of wild flower in NWP was arranged in the order of Achillea sibirica > Lotus corniculatus var. Japonicus > Dianthus chinensis > Plantago asiatica > Taraxacum pla~ycarpum > Viola mandshurica > Aster koraiensis > Vicia tetasperma > Lespedeza stipulacea > Hemerocallis fulva, respectively. The highest seasonal distribution of native wildflower, Achillea sibirica was in spring and summer, Lotus corniculatus var. Japonicus was in autumn. Botanical composition of wild flower in IWP was arranged in the order of Achillea millefolium Coreopsis tinctoria > Silene armeria > Coreopsis lanceolata > Rudbeckia bicolor > Sanguisorba oficinalis > Centaurea cyanus > Chrysanthemum leucanthemum > Dianthus petraeus, respectively. The highest seasonal distribution of introduced wildflower, Silene armeria was in spring, Achillea millefolium was in summer, and Coreopsis tinctoria was in autumn.

This study was conducted to obtain the transformed birdsfoot trefoil (Lotus corniculatus L.) plants with BcHSP17.6 gene using Agrobacterium turnefaciens LBA4404 and we confirmed transformed gene from the regenerated birdsfoot trefoil plants. The expression vector, pBKH4 vector, harboring BcHSP17.6 gene was used for production of transgenic birdsfoot trefoil plants. The callus of birdsfoot trefoil was cocultivated with Agrobacteriurn turnefaciens and transformed calli were selected on kanamycin-containing SH-kc medium to regenerate into plants. The transformed birdsfoot trefoil plants were produced 4 momths after cultivation on BOi2Y medium. The transgenic birdsfoot trefoil plants were analyzed by isolation of genomic DNA and genomic Southern hybridization using a -32P labelled BcHSPl7.6 fragments. (Key words : Birdsfoot trefoil, Transgenic plant. BcHSP17.6 gene, Callus induction, Plant regeneration)

To select the most proper soil for root initiation from stem cuts of Birdsfoot trefoil (Lotus corniculatus L.), eight-week-old stem cuts were cultured on three types of soil [commercial bed soil, decomposed granite (DCG), and river sand] for one month. The results showed that the root initiation ratios on DCG (77.8%) and river sand (70.0%) were relatively high, but the ratio on commercial bed soil (41.1%) was very low. To examine the effect of rare earth (RE) and Indole-3-Butyric Acid (IBA) on root initiation from stem cuts of Birdsfoot Trefoil, stem cuts were cultured on two types of soil (DCG and river sand) with treatment of RE and IBA for one month. The root initiation ratios turned out to be 90.0% (DCG with 60 ppm of RE), 80.0% (river sand with 20 ppm of RE), 96.7% (DCG with 40 ppm of IBA), and 96.7% (river sand with 40 ppm of IBA). These results suggested that the most efficient way for root initiation of Birdsfoot trefoil was to culture the stem cuts on river sand or DCG over 30 days with IBA treatment (40 ppm).
