32종의 해안식물(주로 염생식물)에 대한 유리아미노산 및 총질소함량을 조사하였다. 몇몇 종(참골무꽃과 해란초)을 제외한 모든 식물체는 Pro을 함유하였으나, 번행초, 등골나물아재비 및 갯무에서만, 높은 함량을 나타내어, 이들 식물에서 Pro은 세포질성 삼투물질로 작용하는 것으로 생각된다. 그러나 등대풀, 갯무, 갯방풍, 갯기름나물, 통보리사초, 왕잔디, 갯잔디 등의 식물은 Pro 보다는 hydroxylproline (OH-Pro)을 상당량 축적하였다. 총 아미노산은 갯개미취, 갯질경, 해란초, 순비기나무 및 특히 명아주과와 돌나물과 식물에서 낮은 값을 보였다. 또한 번행초, 등대풀, 갯무, 명아주과 및 콩과 식물은 보편적으로 총 질소 및 수용성 질소함량이 높았으나, 참골무꽃, 해란초, 순비기나무, 통보리사초 및 벼과 식물은 낮은 수준의 질소함량을 보였다. 대부분의 해안식물에서 유리아미노산은 총질소함량에 차지하는 비율이 낮았지만, 등대풀, 모래지치 및 둥근바위솔의 경우 아미노산 질소가 총질소함량의 25∼30%를 차지하였다. 결론적으로, 몇몇 예외는 있지만 세포질성 삼투물질로 널리 알려진 Pro은 조사된 해안식물의 유리아미노산 풀(pool)에서 유의한 몫을 차지하지 않는 것으로 여겨진다.

We investigated the growth response and population regeneration of four halophyte species: Suaeda japonica, Salicornia europaea, Suaeda maritima and Suaeda glauca, when climate change proceeds caused by increased CO₂ concentration and temperature. The plants collected from habitat in 2018 were transplanted into Wagner pots, and cultivated for two years in greenhouse divided into a control (ambient condition) and a treatment (elevated CO₂+elevated temperature). The shoot length of halophytes was measured in July of each year, and the population regeneration rate was measured in October 2019. The shoot lengths of S. japonica and S. glauca had no difference between control and treatment for two years. Those of S. europaea were longer in control than treatment for two years. Those of S. maritima had no difference between control and treatment in 2018 but were longer in control than treatment in 2019. In control, the shoot lengths of S. japonica, S. europaea and S. glauca had no difference between years while those of S. maritima were longer in 2018 than in 2019. In treatment, those of S. japonica, S. europaea and S. maritima were shorter in 2019 than 2018 but S. glauca had no difference between years. The regeneration rates of S. japonica, S. europaea and S. glauca were lower treatment than control, and there was no difference in the regeneration rate of S. maritima. In conclusion, if climate change progresses caused by the increase of CO₂ concentration and temperature, the shoot lengths of S. japonica, S. europaea and S. maritima will be shortened, and the regeneration rate of population will be increased only in the S. maritima.

해안생태공원 조성이 추진중인 인천광역시 논현동 일대 염습지의 식물상 및 식생을 1999년 6월부터 2000년 6월까지 조사하였다. 이 지역에는 소래포구의 조간대를 따라 발달한 자연염습지와 함께 조수가 차단된 폐염전이 있다. 이 지역에서 14종의 염생식물이 조사되었는데, 그중 해흥나물이 가장 많이 분포하고 있었으며, 그밖에 퉁퉁마디, 비쑥, 갯개미취 등도 많이 관찰되었다. 폐염전에서 관찰된 염생식물의 종류는 자연염습지에서 조사된 것과 매우 유사하였다. 그러나, 폐염전과 자연염습지 사이의 제방 지역은 염습지 보다 다양한 종이 자라고 있었는데, 귀화식물도 21종이 관찰되었다. 자연염습지의 식생은 해흥나물-비쑥군집과 해흥나물군집으로 구성되어져 있으며 지역에 따른 큰 차이는 없었다. 한편, 폐염전에서는 해흥나물-퉁퉁마디, 나문재-해흥나물, 갈대-애기부들, 갈대군집 등 다양한 군집이 조사되었다. 식생상관과 종다양도에 기초하여 조사지역을 식생양호지역, 인간활동에 따른 교란지역, 식물고사지역 등의 세 구역으로 나눌 수 있었으며, 해안생태공원 조성에 따른 각 구역의 보존대책을 제시하였다.

해안지대에 서식하는 염생식물인 명아주과의 나문재와 해홍나물, 퉁퉁마디의 염분농도에 따른 생육반응을 조사하여 해안간척지의 녹화용 소재 선발 실험을 ebb & flow system의 양액재배를 이용하여 수행하였다. 배양액은 1/2의 Hoagland 액을 이용하였고 염처리는 NaCl 농도를 0, 50, 200, 400 mM로 처리하여 4개월간 재배하였다. 초장은 나문재와 해홍나물의 경우 0과 50 mM에서 높게 나타났고 그 이상의 NaCl 농도에서 감소하였으나 퉁퉁마디에서는 200mM까지 증가하였다. 생체중과 건물중은 나문재의 경우 NaCl농도 증가에 따라 감소하였으나 해홍나물과 퉁퉁마디의 경우 200 mM까지 증가하였다. 엽록소 함량은 종에 관계없이 NaCl농도가 증가함에 따라 감소하였다. 프롤린은 해홍나물 400 mM 처리구에서 그 함량이 가장 많았다. Water potential은 나문재와 해홍나물에서 무처리에 비해 50 mM에서 유의성 있게 감소하였다.

A study on vegetation in the Mangyeong River and Dongjin River basins and the surrounding regions of the Saemangeum Reclaimed Land was conducted in a series of efforts to determine the expected ecological changes in the salt marshes, to restore their vegetation, to explore the restoring force of halophyte, to examine the community mechanism and, ultimately, to rehabilitate marshy land vegetation along the lakeside, coastal dune and salt marshes of the Saemangeum Project Area. The findings of the study may be summed up as follows: Five species such as Suaeda japonica, Salicornia herbacea, Atriplex gmelini, Aster tripolium and Suaeda asparagoides that are mostly distributed in the estuary of the Saemangeum Reclaimed Land were analyzed to examine the mechanism of halophyte to maintain their community. To find out the strategies of plants for survival and the cause of forming community structure, a research was made as for appearance ratio of young sapling. From the results of laboratory analysis into dynamics of the saplings of halophyte, it was revealed that the germination ratio of the dry area and submerged area decreases in the order of Suaeda asparagoides, Suaeda japonica, Salicornia herbacea, Atriplex gmelini and Aster tripolium.

This study investigates Youl Chon Industrial Complex 1 by dividing into three regions : the drainage site, the area inside the complex, and the seaside. Then each region was subdivided into three areas resulting in a total of nine areas for soil sampling and analysis. After analyzing the physical and chemical properties of the soil, all nine area's pH and EC readings indicated that the soil condition is not suitable for vegetation growth (according to the previous study, the pH level was 5.8 and EC was 2.0dS/m). Therefore, for Youl Chon Industrial Complex 1 to become green, the neutralization and reduction of pH and EC level is needed; first, vegetation through dredging soil, and second, introduction of halophytes is suggested. This study finds out that vertical changes in physical and chemical properties of soils in reclaimed sites are very variable and the result depends on surrounding environments, so it suggested the basic data for building vegetation or reclaimed sites. However, the additional study aiming at various reclaimed sites is required as this study was conducted only to limited areas, and this study has left monitoring analysis as the follow-up task to check the relations between a plant community and soils.

Background: The objective of this study was to determine the relationship between soil environmental factors and halophyte distribution in the west coast of South Korea. Soils of our study sites were categorized into two groups: salt marsh and estuary marsh. Results: Salinity was higher in the salt marsh group than that in the estuary marsh group. However, total nitrogen, silt, and clay contents were higher in the estuary marsh group than those in the salt marsh group. Although altitude had a wider range in the salt marsh group, the mean altitude was higher in the estuary marsh group than that in the salt marsh group. Annual halophytes of seed propagation species were distributed parallel to the coast line on salt marsh. Higher coverage of vegetation was found in the area closer to the coast line. Plant density was higher near dead parental plants in estuary marsh, showing less difference in area that was more distant from the coast line. Conclusions: Results of canonical correspondence analysis (CCA) for vegetation distribution and sediment environmental factors and germination analysis in the coast line showed significant relationship with halophyte distribution. Therefore, they can be used as an indicator of coastal plant movement due to sea level rise.

The diversity and plant growth-promoting ability of fungal endophytes that are associated with five halophytic plant species (Phragmites australis, Suaeda australis, Limonium tetragonum, Suaeda glauca Bunge, and Suaeda maritima) growing in the Buan salt marsh on the west coast of South Korea have been explored. About 188 fungal strains were isolated from these plant samples' roots and were then studied with the use of the internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2). The endophytic fungal strains belonged to 33 genera. Alternaria (18%) and Fusarium (12.8%), of the classes Dothideomycetes and Sordariomycetes, were most rampant in the coastal salt marsh plants. There was a higher diversity in fungal endophytes that are isolated from S. glauca Bunge than in isolates from other coastal salt marsh plants. Plant growth-promoting experiments with the use of Waito-C rice seedlings show that some of the fungal strains could encourage a more efficient growth than others. Furthermore, gibberellins (GAs) GA1, GA3, and GA9 were seen in the Sa-1-4-3 isolate (Acrostalagmus luteoalbus) culture filtrate with a gas chromatography/mass spectrometry.
