  • The purpose of this study was in search of native plant species showing metal-resistant property and excessively accumulating heavy metals in metal-contaminated soil or abandoned mines as well as in evaluation of applicability of phytoremediation. In the study area, species showing excessively accumulating heavy metals were a shepherd´s purse, pampas grass, a Korean lettuce, a Hwansam vine, the Korean persicary, a foxtail, a goosefoot, and a water pepper. The first screened plant species in Sambo mine were as shepherd's purse, Korean lettuce and pampas grass Among them the shepherd´s purse can be excluded because it is a seasonal plant and has lower removal capacity for heavy metals. The Korean lettuce was also excluded because of having lower removal capacity for heavy metals. Pampas grass is a highly bionic plant species constantly growing from spring. However it has weak points such as little accumulation capacity for zinc as well as small values of an accumulation factor and a translocation factor. Another problem is regarded as removal of roots after the clean up if pampas grass is applied to a farmland. In Sanyang mine, wormwood and Sorijaengi were considered as adaptable species.

  • This study is carried out through ecological situation of native Bupleurum latissimum habitats and the research of environmental conditions for conservation of native sites, restoration of alternative habitats and preliminary data for application of useful medicinal plant. Native Bupleurum latissimum habitats were distributed on lower and middle part of the mountain from Altitude 54m to 185m, and the directions of slope were researched as usually northen and western slope. As a result of phytosociological research in 12 stands of native Bupleurum latissimum habitats, they were seperated to two communities(Bupleurum latissimum typical community and Bupleurum latissimum-Galium spurium community) in accordance with containable rate of the organic matter and soil hardeness. Soil condition is usually constituted as loamy sand and clay loam. Bupleurum latissimum is propagated in valuable soil conditions. Bupleurum latissimum lives with Morus bombycis, Reynoutria sachalinensis in Bupleurum latissimum typical community and Thalictrum aquilegifolium, Stellaria media, Hedera rhombea etc. is appeared with Bupleurum latissimum in Bupleurum latissimum-Galium spurium community. Especially, companion species were researched as Aster glehni, Dystaenia takeshimana and so on. The flora of vascular plants in this study is 44 families, 88genus 82species, 2 subspecies, 14 varietas, 4 forma and total 102 taxa. Plants of compositae occupied 10.78% among whole of them.

  • 본실험은 울릉도와 오대산 산마늘 자생종의 종자의 특성 및 물리·화학적 처리에 의한 종자의 발아 양상과 가온개시기에 따른 종구의 휴면 특성을 조사하기 위해 수행하였다. 종자의 특성에 있어 모양, 색, 탈립성은 2개 자생종이 비슷하였으나 그 외의 형질에서는 달랐다. 천립중는 울릉도 자생종이 14.8g 으로 오대산 자생종에 비해 2.1배였다. 울릉도 자생종은 채종 즉시 파종한 처리에서만 발아하였으며 화학제 처리효과는 없었다. 또한 무처리 암장태에서 발아율이 86%, 평균발아일수 42일, 발아계수 2.05이었으며, 저온유수 및 저온습윤혼용처리에서는 발아율이 감소하였다. 오대산 자생종은 무처리 암장태에서 발아율이 70%, 평균발아일수 47일, 발아계수 1.0이었는데, 저온습윤 처리에서는 명장태에서 발아율 82%, 평균발아일수 47일, 발아계수 1.75로 광에 대한 반응이 달라졌다. 오대산 자생종 종구는 초상후 45일 이후가 되어야 휴면이 타파되어 가온개시시기로써 적합할 것으로 보여진다.

  • This study was conducted to find out appropriate rates of seed mixture of both native and foreign plants in order for stabilization of early afforestation and proper vegetation on road slope. The results are summarized as follows: 1. Characteristics of germination : After seeding, 2 weeks for both Lespedeza bicolor and Lespedeza cuneata, and 4 weeks for both Arundinella hirta and Zoysia japonica were needed for vigorous germination, and 1-4 wee17s for 3 cool-season grasses were spent for gradual germination. 2. Plant height : There was no difference between Lespedeza cuneata and Lespedeza bicolor in plant height by 7 treatments. As mixture rates of cool-season grasses were lowered, plant height of Arundinella hirta became longer. Descending order of co81-season grasses for plant height was Tall fescue, Perennial ryegrass and Creeping redfescue. 3. Number of tillers : The number of tillers tended to increase in the experimental plots where competition was low. 4 Ground cover rate : Ground cover rate was the highest in Mixture IV (96.7%) and was fluctuated from 13.3% on Sept. 13 to 45% on Nev. 3 in Mixture III. Descending order of gronud cover rates in 7 treaments was Mixture IV, Mixture III. Mixture II, Mixture Ⅶ, Mixture V, Mixture Ⅵ, Mixture I, and Mixtur III when measured on Oct. 13 5. Visual assessment: High preferences were observed on Mixture IV and Ⅶ In sun the best seed mixtures were Mixture IV and Ⅶ. It meant that (1) either mixture of 70% the native plants with 30% cool-season graaes or (2) mixture of 80% the native plants with 20% cool-season glasses was best for this study.

  • Populations of plant-parasitic nematodes were evaluated in soil and root samples from areas planted with passion fruit, or covered with adjacent native cerrado vegetation, in five different cropping regions of the Brazilian Federal District. From July 2007 to January 2008, twenty samples had been collected in five Rural Centers (N$\acute{u}$cleo Rural-NR) planted with passion fruit. In five sites, samples were also collected in native cerrado vegetation. Specimens of nine genera of plant-parasitic nematodes (Meloidogyne, Helicotylenchus, Rotylenchulus, Scutellonema, Pratylenchus, Paratylenchus, Hemicycliophora, Xiphinema and Criconemoides) were found in the present survey. Important nematode pathogens, such as Rotylenchulus reniformis and Meloidogyne spp. were observed in the passion fruit plantations throughout five major producing regions of the Brazilian Federal District.

  • This study investigated the effect of vegetation mat on plant growth and salt reduction in the soil treated with high concentration deicing salt. In order to measure soil chemical characteristics and plant growth, three native groundcover plants (Dendranthema zawadskii var. latilobum, Dendranthema boreale, and Kalimeris yomena) were grown in each of the three plastic containers (50.0 cm width × 35.0 cm length × 8.5 cm deep) with a high concentration treatment of calcium chloride deicing salt. There were two treatments: control, and BVM that combines B (blanket) and VM (vegetation mat). 1,600 g of soil was placed on the top of the drainage layer with 290 g of perlite, 100 seeds each of the three native plants with three repetitions were sowed, and 10 g/L of calcium chloride deicing salt was added in the treatment. As a result of the chemical properties of soil, soil in control treatment was acidic and soil electrical conductivity in BVM was the lowest. Also, exchangeable cations (K+, Ca2+, Na+, and Mg2+) in soil and all the three plants were significantly decreased in the BVM treatment. Meanwhile, the germination rate of Dendranthema zawadskii var. latilobum was the highest under high concentration deicing salt in compared to the two plants. Overall, three native groundcover plant growth was higher in the BVM than control treatment significantly. These results suggest that the treatment of blanket vegetation mat has a positive effect on soil and plant growth in soil damaged by deicing salt.

  • Naturalized populations of two alien plants were newly found, and we describe their morphological characteristics and habitats with photographs. One is a member of Juncaceae, Juncus torreyi Coville, and was newly found at a pool of a beach in Gangwon-do. This rush is native to North America and belongs to the sect. Ozophyllum (subgen. Juncus) according to certain morphological characteristics, such as its racemose inflorescence, the absence of floral bracteole, and unitubular leaves with perfect septa. J. torreyi is easily distinguishable from Korean rushes by its long rhizomes with swollen nodes and globular head with 25-100 flowers. Its introduction into Japan and Europe was reported, but the ecological risk associated with its over-dispersal is not known. The other alien plant is a submerged plant, Egeria densa Planch. (Hydrocharitaceae), which was found in streams in Gyeongsangbuk-do and ditches in the Busan-si area, both of which being in the watershed of the Nakdong River. Egeria densa is similar to Hydrilla verticillata (L.f.) Royle, which is native to Korea. However, it is distinguished from H. verticillata by its larger flowers and lack of overwintering organs. This alien plant is native to South America and was introduced for aquarium gardening and naturalized around the world. Egeria densa is treated as a malignant weed due to its asexual reproduction and rapid growth. Size changes and the number of populations of E. densa must be investigated.
