시금치 엽록체의 광계의 (光系) 2 활성에 미치는 추출용매와 반응용액의 영향
권병규(Byung Kyu Kwon),양운진(Un Jin Yang) 한국식물학회 1976 Journal of Plant Biology Vol.19 No.4
This work deals with different extraction media and reaction mixtures on photosystem Ⅱ activity of Spinach chloroplasts. The photoreduction rate of ferricyanide and DPIP by intact chloroplasts which extracted with four kinds of extraction media; S-Tris-N pH 7.2, 8.0, S-Tricine-N pH 7.2, 8.0, was measured in five kinds of reaction mixtures; S-Tris-N pH 7.2, 8.0, S-Tricine-N pH 7.2, 8.0, 0.05 M-Tris pH 7.2. The extraction medium which shows the highest photoreduction rate was S-Tris-N at pH 7.2, and S-Tricine-N at pH 8.0. As to the reaction mixture, S-Tricine-N pH 8.0 showed the highest rate. On the complex effects of extraction media and reaction mixtures, the highest photordeuction rate of Hill oxidant by intact chloroplasts was obtained by S-Tris-N pH 7.2 extraction medium and S-Tricine-N pH 8.0 reaction mixture. The second highest activity was obtained by S-Tricine-N pH 8.0 extraction medium and reaction mixture.
박실지에서 계절적으로 조사한 식물성 플랑크톤상과 환경변이에 관한 연구
양운진,이호원 慶南大學校 附設 基礎科學硏究所 1997 硏究論文集 Vol.11 No.-
박실지 자연호소에서 1996년 8, 11월 및 1997년 3월과 5월등 4회에 걸쳐 식물성 프랑크톤 군집을 조사하였다. 본 조사 결과 5강 45속 95종 10변종으로 총 106분류군이 출현하였으며, 8월이 31분류군. 11월이 30분류군 그리고 3월이 41분류군 그리고 5월이 38분류군으로 월별 종조성은 큰 차이가 없었다. 그리고 이들의 각 강별 구성을 살펴보면 규조강이 49.1%, 유글레나강이 15.1%, 녹조강이 24.5%, 남조강이 6.6%로 황갈조류강이 4.7%의 순으로 유글레강의 구성비가 높고 녹조강의 구성비가 낮은것이 특징이다. 현존량은 11월이 1.94개체/㎖, 3월이 2,046개체/㎖, 8월이 2,850개체/㎖로 5월에는 3,542개체/㎖로 나타났으며, 그리고 8월에는 Microcystis aeruginosa (2.090), 11월에는 Fragilaria corotenesis(1.584) 그리고 3월에는 Dinobryon divergens (1.306)가 5월에는 Scenedesmus ecornis (1.700)가 우점하였다. Species composition and dynamic of the phytoplankton community were studied in the Pacsil Swamp. August 1996 to May 1997. 106 taxa of 5 classes.45 genera. 95 species. and 10 varieties were observed. The composition of species was as follows: Bacillariophyceae is 49.1% Euglenophyceae is 15.1% Chlorophyceae is 24.5%. Cyanophyceae is 6.6%. Chrysophyceae is 4.7% and so on. The standing crops of phytoplankton varied from 1.941 cells/㎖ to 3.542 cells/㎖. The dominent species were Microcystis aeruginosa in the August 1996. Fragilaria corotenesis in November 1996. and Dinobryon divergens in March 1997. and Scenedesmus ecornis in May 1997.

In order to establish paleoenvironments conditions and lake's diatom assemblages of change core from the Changnyong-gun was drilled in swamp Woopo. A total of 39 taxa(2 orders 3 suborders 8 families 12 genera 31 species 3 variety 5 unidentified species) was identified consisting of most of Freshwater taxa, 3 taxa of tidal and 9 taxa of fossil plants. It is 37 taxa of pennales and 2 taxa of centrales and then 25 taxa of Naviculaceae(64.1%) was identified. Especially 7 taxa of Navicula(17.9%) and Cymbella(12.8%) Nitzschia(12.8%) was 5 taxa respectively. 79.5% of a total taxa was appearanced in 968.9~946.9cm at sediments and color of sediments were yellowish brown(2.5Y5), grey(7.5Y5), mottled clay silt and sand layer were existence each unit.
