  • Background: To reveal establishment strategy of Sparganium erectum, we tried to find realized niche of adults through field survey and effects of water level on the establishment process through mesocosm experiments. Results: In the field survey, the height and coverage of community living in deeper water were greater than those of community living in shallow water. There was no statistically significant difference (p > 0.05) in the means of water and soil properties between the two communities. In mesocosm experiments, we found no correlation between water levels and germination rates, but S. erectum seedlings have characteristics of post germination seedling buoyancy when S. erectum seeds germinated in inundation conditions. Shoot height, total leaf length, and survival rates of sinking seedlings in shallow water levels at -5, 0, and 5 cm were higher than those in deeper water levels at 10 and 20 cm. Floating seedlings established in water levels of 3 and 6 cm only. The seedlings could live up to 6 weeks in floating state but died if they were unable to establish. Conclusions: The water level around adult S. erectum communities in the field were different from the water level at which S. erectum seedlings can survive in the mesocosm experiments. The findings provided not only understanding of S. erectum habitat characteristics but also evidence to connect historical links between the early seedlings stage and adult habitat conditions. We suggested the logical establishment strategy of S. erectum based on the data.

  • The anti-diabetic effect of Cirsium setidens water extract and the combinations with Bletilla striata, Cymbidium kanran, and Sparganium stoloniferum Buch.-Ham. ethanolic extracts had been studied. The combination of four extracts (3:1:1:1) showed larger anti-diabetic activity in vitro and in vivo. It is notable that the single water extract from C. setidens exhibited more effective anti-diabetic effect than most of the combinations. We also investigated whether fermentation process was promoted the anti-diabetic activity. The data suggested the fermentation product of combination of four extracts (3:1:1:1) exhibited the strongest activity both in vitro and in vivo, which was higher than the non-fermented group. The result indicated the fermentation and the appropriate combination of extracts enhanced the anti-diabetes activity.

  • The purpose of this study was to create an artificial wetland in rooftop greening. We monitored species and changes of flora in wetland and rooftop greening. As shown the consideration and possibility of supplying the artificial wetland in rooftop greening through flora in wetland, this study tried to find methods to create a efficient flora space. This results are listed as belows. The species were applied to artificial wetland in rooftop greening and come up to 'General standard for selecting plants' among hydrophyte in wetlands. The plants of Potentilla kleiniana, Penthorum chinense, Scirpus radicans, Scirpus triqueter, Veronica undulata, Mentha arvensis var. piperascens, Salvia plebeian, Sagittaria aginashi, Aneilema keisak, Stachys riederi, Alisma canaliculatum, Eclipta prostrata, Sparganium stoloniferum turned out an appropriate species. This research was expected to create a various environment and component of species by introducing many types of plants in ecological wetland on rooftop greening.

  • 강원도 인제군에 위치한 대암산 용늪(1,280m)의 습원 식물상과 식생에 대하여 Braun-Blanquet(1964) 의 방법으로 1998년 6월 13일부터 14일까지와 8월 7일부터 8일까지의 기간에 실시하였다. 습원내의 소산식물은 선태류 4과 4속 7종, 유관속식물 49과 127속 153종 30변종 1품종으로 총 191종류였다. 식생은 가는오이풀 군락군(Sanguisorba tenuifolia var. alba community group)으로 11개군락으로 구분되었다. 즉, 습원의 주요 식물군락은 삿갓 사초군락(Carex dispalata community), 물이끼 군락(Sphagnum palustre community)이었으며, 그 훼손지의 재생지역에는 솔잎사초 군락(Carex biwensis community), 청비녀골 풀 군락(Juncus papillosus community)이 함께하고 있었다. 또한 지하수위가 저하된 건조지역에는 진퍼리새 군락(Malinia japonica community)을 중심으로, 꼬리조팝나무 군락(Spiraea salicifolia community), 산새풀-꽃쥐손이 군락(Geranium eriosteman var. megalanthum-Calamagrostis langsdorffii community) 외에 골풀 군락(Juncus effusus var. decipiens community), 버드나무 군락(Salix koreensis community), 동의 나물 군락(Caltha palustris var. mem branacea community), 흑삼릉 군락(Sparganium stdoniferum community)으로 이루어져 있었다. 특히 그간에 실시되어온 1969년, 1976년, 1988년의 조사와 금번의 조사를 비교 분석해본 결과, 습원의 삿갓사초 군락, 물이끼 군락의 규모가 감소되고, 진퍼리새 군락이 침입되어 번식하며 그 규모가 커지고 있었다. 이는 스케이트장 조성과 가뭄의 영향 등 습원의 건조화 때문이나 인간의 출입과 훼손에 의한 교란이 없다면 고층습원의 회복 및 재생이 가능할 것으로 판단되었다.

  • 동백동산 습지는 못과 한시적 못으로 구분되었다. 어리연꽃군락, 흑삼릉군락, 좁은잎미꾸리낚시군락, 송이고랭이군락, 물고추나물군락, 청비녀골풀군락, 진땅고추풀군락, 중대가리풀군락, 수궁초군락, 기장대풀군락 및 참느릅나무군락의 11개 식물군락이 성립해 있다. 어리연꽃 군락은 동백동산입구에 위치한 한 못에 성립해 있고 좁은잎미꾸리낚시군락은 그 못의 가장자리에 성립해 있다. 흑삼릉군락은 수심이 비교적 낮은 인근의 못에 성립해 있고 그 못의 가장자리에도 좁은잎미꾸리낚시군락이 성립해 있다. 한시적 못은 과거 식수원으로 사용되었고 일부에서는 가축의 물먹이공간으로도 사용되었다. 송이고랭이군락은 그 못의 중심으로서 가장 습한 곳에 성립하고 청비녀골풀군락-진땅고추풀군락-물고추나물군락 및 수궁초군락이 그곳으로부터 멀어짐에 따라 동심원 구조로 성립해 있다. 참느릅나무군락은 상대적으로 더 건조한 한시적 못에 성립해 있다. 본 연구는 한국에서 한시적 못에 대해 처음으로 이루어진 연구이다. 따라서 본 연구에서 밝혀진 대부분의 식생유형은 습지에 대한 기존의 연구와 다른 새로운 유형으로서 그 가치가 있다.

  • This study aims to find out the growth characteristics of riparian plants on the artificial floating islands (AFI). Three types of experiments were performed. The vegetation growth were compared by the plant-supporting materials; natural cotton mat, coir mat on the AFI or in the water, and natural soil at the waterfront. Major findings are; 1. The survival rate of riparian plants was 100% on both coir-mat and cotton-matislands, which implies that we may substitute cheaper cotton for expensive coir-mat. 2. Both natural cotton mat and coir mat were good for the growth of plants. Especially, the natural cotton mat was good for Sparganium stoloniferum and Miscanthus sacchariflorus, and the coir mat was good for Typha latifolia. 3. The growth rate of stem and root showed difference between the stem-removed plants and stem-remaining plants. As a whole, the growth rate of stem-removed plants was bigger than the one of stem-remaining plants. 4. The growth rate of plants showed difference between those grown on the AFI and those grown in the water. The growth rate of plant on the AFI was bigger than the one in the water. 5. The growth rate of plants on the AFI was bigger than the one on the natural soil at the waterfront.
