In order to elucidate the ecophysiological characteristics of coastal plants, we collected them on salt marsh and sand dune, and analyzed inorganic ($Na^+,\;K^+,\;Mg^{2+},\;Ca^{2+}$) and organic solutes (soluble carbohydrate, glycine betaine). Chenopodiaceous plant species (Atriplex gmelini, Salicornia europaea, Salsola collina, Suaeda glauca, Suaeda japonica) showed a tendency to accumulate inorganic ions such as $Na^+\;and\;Cl^-$ instead of $K^+$. However, Chenopodium serotinum which lives in ruderal habitat contained more $K^+$ and less $Na^+$ than the other Chenopodiaceous plants. Most Chenopodiaceous plant species maintained very low level of soluble $Ca^{2+}$ and relatively low concentration of carbohydrates and showed high concentration of glycine betaine which is among the most effective known compatible solutes in the leaves of plant under drought and saline conditions. On the other hand, plant species which belong to Gramineae (Ishaemum anthephoroides, Phragmites communis, Zoysia sinica) and Cyperaceae (Carex kobomugi, Carex pumila) absorbed $K^+$ selectively and excluded $Na^+\;and\;Cl^-$ effectively regardless of habitat conditions, and they accumulated more soluble carbohydrate as osmoticum than Chenopodiaceous plants. These results suggested that physiological characteristics such as high storage capacity for inorganic ions (especially alkali cations, chloride) and the accumulation of glycine betaine in chenopodiaceous plants and $K^+$-preponderance, an efficient regulation of ionic uptake (exclusion of $Na^+\;and\;Cl^-$) and the accumulation of soluble carbohydrate in monocotyledonous plants enable them to grow dry and saline habitats.

This study examined the halophyte community and soil analysis according to habitat in representative 18 salt marshes of southern and western coasts of Korea from July 2006 to April 2008 and suggested basic materials for vegetational restoration of these aras. First, the survey area was classified into coastal and estuarine marshes. Then, the coastal marshes were classified into clay marsh, sand gravel marsh, and sand marsh, and the esturarine marshes, into salt swamp and estuary marsh. Major plant communities according to habitat pattern were Phragmites communis, Carex scabrifolia, and Suaeda japonica community in the clay marsh; Phragmites communis, Zoysia sinica, Carex scabrifolia, Salicornia herbacea, Artemisia fukudo, Suaeda martima community in the sand gravel marsh; Elymus mollis, Carex kobomugi, and Vitex rotundifolia community in the sand mars; Phragmites communis, Zoysia sinica, Suaeda martima, and Carex scabrifolia community in the salt swamp, and Suaeda japonica, Phragmites communis, Carex scabrifolia, and Suaeda asparagoides community in the estuary marsh. The soil environment of halophyte community area showed a difference to soil and halophyte community according to habitat characteristics of halophyte. Thus, to restore salt mashes in the coast area, it is advantageous for the stable settlement, germination, and growth of halophyte to grasp physical and physicochemical characteristics of habitat soil in the salt marshes, to select halophyte suitable to these habitat conditions, and to expand gradually in the natural vegetation area after transplantation.

Forty-two endophytic fungi were isolated from the roots of coastal plants, such as Aster sphathulifolius Maxim., Aster tripolium L., Phragmites australis, and Puccinellia nipponica Ohwi, naturally growing in Taean peninsula. The identity of the endophytic fungal strains was analyzed using the sequence of internal transcribed spacer regions. All fungi belonged to the phylum Ascomycota, and they were classified into eight orders (Botryosphaeriales, Capnodiales, Diaporthales, Dothideales, Eurotiales, Helotiales, Hypocreales, and Pleosporales) and thirteen genera (Alternaria, Aureobasidium, Cadophora, Cladosporium, Davidiella, Diaporthe, Fusarium, Gibberella, Macrophomina, Metarhizium, Neosartorya, Penicillium, and Phoma). Among the analyzed fungi, the fungi belonging to the genus Penicillium in Eurotiales were the most widely distributed. The host plant Aster tripolium L. was found to contain the most diverse endophytic fungal species among the coastal plants.

갯대추(Paliurus ramosissimus (Lour.) Poiret)는 갈매나무과에 속하는 낙엽관목으로 드물게 교목으로 자라며, 우리나라에서는 제주도에만 분포하는 것으로 알려진 희귀식물이다. 이 종의 주요 분포대는 동아시아의 열대 및 아열대로 제주도는 위도 상 북한계로 알려져 환경부 지정 보호식물 제 39호로 지정\ulcorner보호하고 있으나 자생지에 대한 구체적인 조사가 이루어진 바 없다. 따라서 본 연구는 자생지의 현황과 생육상황을 파악하여 자생지 보전에 기여하고자 실시하였다. 갈매나무과는 세계적으로 58속 900여종이 분포하고, 갈매나무속(Genus Rhamnus), 헛개나무속(Genus Hovenia), 대추속(Genus Zyzyphus) 등이 주요 속으로 알려져 있으며, 그 중 갯대추속(Genus Paliurus)은 과실이 건과이고 날개가 있는 특징으로 다른 속과 구별된다. 꽃은 양성화로 7월~9월에 피고, 화서는 수 개의 꽃이 달리는 취산화서, 열매는 반구형으로 과병에 연한 갈색의 복모가 있으며 얕게 3부분으로 갈라져 각 실마다 편평한 공모양의 종자가 1개씩 들어있다. 갯대추 자생지는 제주도의 동부지역인 북제주군 구좌읍 김녕에 1개소, 남부지역인 남제주군 남원읍 태흥에 1개소, 서부지역인 북제주군 한경면 용당에 1개소, 한경면 용수에 1개소, 한경면 신창에 3개소 및 남제주군 대정읍 일과에 2개소 등 총 6지역 9개소였다. 분포지는 해발 20m이하의 해안가 토심이 얕은 암반 위였으며, 주로 해수의 영향을 직접적으로 받는 곳이었다. 생육상황을 조사한 결과 바다 쪽으로 갈수록 수고가 급격히 낮아지는 경향을 보였으며, 최소 0.3m, 최대 4.5m였고 평균 1.6m 정도였다. 수반종으로는 순비기나무와 갯기름나물, 갯까치수영 등 해안식생의 구성종이 대부분이었으며, 돌가시나무, 상동나무 등도 혼생하는 것으로 조사되었다. 자생지 위협요인으로는 양식장 시설, 도로개발, 해안매립 및 쓰레기 투기 등과 같은 인위적 간섭과 상동나무 등 주변식물의 피압이 주 요인이었다. 한편 갯대추는 희귀식물로서 뿐만 아니라 해류에 의해 전파되는 종으로 알려져 있어 제주도의 식물지리학적 연구에도 좋은 연구대상이 되고 있으므로 종 보전대책 및 자생지 보호에 대한 추가적인 연구가 필요하다.

This study was carried out to select suitable plants for beach revegetation as a preliminary study for quantifying the effect of decreasing sand movement. After planting some herbal plants in field, monitoring of temporal change of vegetation coverage which was index of the growth rate was conducted. Through literature reviews, 24 candidate plants for beach revegetation were selected, then seven species of them, Peucedanum japonicum Thunb., Dianthus japonicus Thunb. ex Murray, Sedum oryzifolium Makino, Sedum takesimense Nakai, Sedum spectabile Boreau, Farfugium japonicum (L.) Kitam., Aster sphathulifolius Maxim. were picked through salinity tolerance experiments in laboratory. Seven species selected by salinity tolerance experiments and two additional herbal plants, Prunella vulgaris var. lilacina Nakai and Linaria vulgaris Mill., not the candidates, were nine final species which were planted in the beach around Osan port, Uljin, Korea. The changes of vegetation coverage of each species were investigated from photos periodically taken for about a year using image processing methods. As a result of the monitoring, Sedum takesimensei, Dianthus japonicus and Aster sphathulifolius were observed with high coverages during the whole monitoring while Prunella vulgaris var. lilacina and Linaria vulgaris were observed with low coverage during the same period. Consequently, Sedum takesimensei, Dianthus japonicus and Aster sphathulifolius were concluded as the most suitable plants for beach revegetation. Furthur study to quantify the effects of decreasing sand movement by the selected species is needed.
