본 연구에서는 벽면녹화시스템에 식재된 사초류의 방위(광도)에 따른 생육반응 및 옥상녹화시스템에 식재된 사초류의 토양깊이에 따른 생육차이 등을 조사하고자 하였으며, 사초류가 다양한 형태로 활용될 수 있도록 기초적인 자료들을 제시하고자 하였다. 벽면녹화 및 일반컨테이너의 온도변화를 비교한 결과, 벽면녹화의 경우 온도가 낮아지는 것을 알 수 있었고, 주로 화창한 날씨가 유지된 8~9월 동안에 차이가 뚜렷하였다. 테스타시아사초, 에버골드 및 털대사초 등은 높은 광도에서 생육이 우수하고($0{\sim}1799{\mu}M{\cdot}m^{-2}{\cdot}s^{-1}$), 상록갈사초, 줄무늬사초, 대사초 및 흰줄무늬실사초는 낮은 광도에 적합한 것으로 판단되었다($0{\sim}786{\mu}M{\cdot}m^{-2}{\cdot}s^{-1}$). 광도가 낮을수록 식물의 색이 선명해져 관상가치가 증가하였는데, 본 연구에서는 무늬의 변화에 대한 고려가 이루어지지 않아 추가적인 연구가 이루어져야 할 것으로 사료되었다. 토양깊이별 수분함량은 10cm의 경우 배수층 없이 혼합용토로만 이루어져 높게 유지되는 것으로 나타났고, 대부분의 사초류들도 10cm 깊이에서 생육이 좋았다. 에버골드, 대사초 및 테사타시아사초등은 토양깊이 20cm에서 생육이 우수하였다. 흰줄무늬실사초와 털대사초 노란무늬종은 토양깊이 40cm에서 생육이 좋은 것으로 나타났다. 본 연구에서는 사초류가 10~20cm의 낮은 토심에서도 생육이 우수하여 옥상녹화 소재로 충분히 도입 가능할 것으로 판단되었다.

본 실험에서는 염토지대에 조경용 식재로 사용이 가능한지 알아보기 위해 여러 과에 속하는 자생식물의 염 스트레스에 대한 내염성 정도를 조사하였다. NaCl의 처리에 따른 식물의 생육반응과 이온흡수 특성도 파악하여, 여러 식물에 대한 내성 정도를 구명하고자 하였다. 실험재료로 노랑꽃창포, 밀사초, 여우꼬리사초, 줄사초, 홍노줄사초, 애기부들, 바위 및 땅채송화 등을 이용하였다. 염농도는 0, 100, 200, 300mM로 처리해 주었다. 처리 4주 후 지상부 및 뿌리의 생체중 건물중, 엽내 무기이온 함량 등을 조사하였다. 줄사초, 왕밀사초, 여우꼬리사초, 노랑꽃창포 등은 NaCl 200mM의 고농도에서도 잘 견디는 초종으로 판단되었다. 홍노줄사초, 애기부들 등은 지하부 생육이 NaCl 100mM의 농도에서 저하되어, 지상부다 뿌리가 민감하게 반응하는 것으로 나타났다. 홍노줄사초는 K의 흡수량이 감소되었고, Na/K의 비율은 300mM의 농도에서 3으로 다른 종보다 높은 경향을 보였다. 애기부들은 NaCl의 농도가 증가됨에 따라 K, Ca, Mg의 흡수량이 일시 증가하다가 200mM의 농도부터 감소하는 경향을 보였고, Na/K의 비율은 300mM의 농도에서 0.8로 조사되었다. 땅채송화 및 바위채송화 등도 NaCl 100~200mM의 범위에서 지상부 및 지하부의 생육이 영향을 받는 것으로 나타났다. 바위채송화는 NaCl의 농도가 증가됨에 따라 K, Ca, Mg의 흡수량이 일시 증가하다가 200mM의 농도부터 감소하는 경향을 보였고, 땅채송화는 염농도에 따라 흡수량이 영향을 받지 않는 것으로 나타났다. Na/K의 비율은 300mM의 농도에서 모두 1로 조사되었다. 그러므로, 여우꼬리사초, 왕밀사초, 줄사초, 노랑꽃창포 등은 식물의 생육 및 이온흡수 특성을 고려할 때 NaCl 200mM의 고농도에서도 잘 견디는 초종으로 판단되었고, 특히 사초과 식물들의 내염성이 검증되어 앞으로 많이 활용될 수 있으리라 사료되었다. 홍노줄사초, 애기부들, 바위채송화, 땅채송화 등은 NaCl 100mM의 농도에서도 뿌리의 생육이 저하되었으며, 염처리에 따른 잎의 이온흡수특성은 뚜렷한 경향을 보이지 않았다.

The genome size is defined as the amount of DNA in an unreplicated gametic chromosome complement and is expressed as the 1C value. It is a fundamental parameter of organisms that is useful for studies of the genome, as well as biodiversity and conservation. The genome sizes of Korean plants, including Carex (Cyperaceae), have been poorly reported. In this study, we report the genome sizes of 43 species and infraspecific taxa of Korean Carex using flow cytometry, and these results represent about 24.4% of the Carex species and infraspecific taxa distributed on the Korean peninsula. The Plant DNA C-Value Database (release 7.1) updated with and now including our data (a total of 372 Carex accessions) shows that the average genome size of members of the Carex species is 0.47 pg (1C), and the largest genome (C. cuspidate Bertol.; 1C = 1.64 pg) is 8.2 times larger than the smallest (C. brownii Tuck., C. kobomugi Ohwi, C. nubigena D. Don ex Tilloch & Taylor, and C. paxii Kuk.; 1C = 0.20 pg). The large genomes are frequently found in the subgen. Carex, especially in sect. Aulocystis, sect. Digitatae, sect. Glaucae, sect. Paniceae, and sect. Siderostictae. Our data updates the current understanding of genome sizes in Carex. This will serve as the basis for understanding the phylogeny and evolution of Carex and will be especially useful for future genome studies.

Up to now, there have been done much efforts in regard to nitrate reductase activity (NRA) of dicotyledonous herbs and important crop monocotyledons, but few to wild plants having canopy structure such as Carex. The objective of the present study are to determine: a) the optimum in vivo NR assay conditions for leaf samples of Carex species, b) changes of NRA according to section within leaf and leaf ages, c) diurnal variations. Optimized assay media of each Carex species were determined. NRA of C. rostrata adapted to oligotrophic habitats is readily saturated at lower substrate concentration than those of C. distans and C. gracilis, adapted to meso- and eutrophic habitats, respectively. All Carex species investigated have higher NRA in leaves than in roots. NRA of all species showed maximal values at the middle section of each leaf and in the youngest fully expanded leaves. Compared to C. gracilis, NR in leaves of C. distans was adapted readily to the light period. On the whole, Carex showed rather delayed diurnal variation. Even if the in vivo nitrate reductase assay based on nitrite estimation does not give an accurate estimation of total nitrate reduced, it still serves as a useful tool to find out relative differences in varying environmental conditions. Additionally, in vivo RNA measurements are helpful to understand nitrate reduction and basic nitrogen metabolism of Carex species having different canopy structure.

This study was carried out to investigate vegetation of Rhododendron mucronulatum habitat in Mt. Biseul to recommend basic information for synecological characteristics and management methods. The survey was carried out from May to July, 2011 and totally 46 vegetation data including 42 families 93 genera 108 species 16 varieties and 5 forma were collected and analyzed. Among the investigated 129 taxa, the numbers of rare plant resources were summarized as 19 taxa; The rare plants designated by Korea Forest Service, the specific plants by floristic region and the endemic plants were listed as 3 taxa, 15 taxa and 4 taxa, respectively. Rhododendron mucronulatum habitat of Mt. Biseul was classified into 3 plant communities (Carex lanceolata-Rhododendron mucronulatum community, Potentilla dickinsii-Selaginella rossii community, Carex lanceolata-Quercus mongolica community). Carex lanceolata-Rhododendron mucronulatum community was subdivided into Tripterygium regelii subunit and Miscanthus sinensis for. purpurascens subunit by human interference degree. And synecology, syndynamics, synchorology of these plant communities were identified, and Site-species ordination analysis by Principal Coordinate Analysis (PCoA) reflected that human impact, soil moisture condition were main ecological factors determining the distribution pattern of classified plant communities. Therefore these plant communities correspond to quite distinctive 4 habitat types : unstable-dry type=Miscanthus sinensis for. purpurascens subunit, unstable-moderate type=Tripterygium regelii subunit, stable-dry type=Potentilla dickinsii-Selaginella rossii community, stable-moderate type=Carex lanceolata-Quercus mongolica community. Finally, through the vegetational diagnosis, proper management methods such as a limit on the access of visitors, planting of native woody plants after removing unwanted vines or grass were suggested.

In the moor of Mt. Dae-am, the following communities are seen in successive order ranging from the north to the south; the Sanguisorba Argutipens-Carex jaluensis community, the Carex jaluensis-Sanguisorba Argutipens-Sphagnum community, the Sphagnum cymbifolium-Carex jaluensis community, the Carex jaluensis-Sanguisorba Argutipens community and the Calamgrostis Langsdorfii-Ottelia alismoides community. The properties of the peats vary according to the community type, that is, nutrients such as organic matter, total nitrogen, exchangeable K and Mg in the soil tend to decrease as the plant communities shift from the north to the south. The pH range for eleven stations samples was 3.9 to 5.7, and the meadian is 4.6. The content of exchangeable Ca decreases from station to station successively towards the center which is poor in calcium. Presumably there appears to be a clear correlation of Sphagnum cymbifolium with the amount of exchangeable Ca and value of pH produced in bogs by the breakdown or organic residures. The nutrient content of the representative plants of the moor shows no definite relation with the station of their habitats.
