신창남 충남대학교 1985 忠南科學硏究誌 Vol.12 No.1

The activity of alkaline phosphatase was investigated to understand the role of this enzyme in the metabolism of cell division of Ankistrodesmus falcatus. The results were summarized as follows : 1. There were changes in cell number with light period. The minimum cell number was 0.96×10 exp (5) cells/ml at 3-4 a. m. and the maximum cell number was 1.61×10 exp (5) cells/ml at 4-5 p.m. On the other hand, the mean-cell-number was 1.25×10 exp (5) cells/ml. 2. The growth rate of cells showed a quadric curve and had a maximum value in the light period. 3. The cell sizes were changed with light period as in the cell number and were smaller at 4 p.m. than at 6-7 a. m. 4. The activity of alkaline phosphatase was in the range of 0.24×10 exp (-2)-0.44×10 exp (2) PPNP μM/10^5 cells/hr and was maximum value at 6-7 a. m. From these results, it was suggested that the alkaline phosphatase of Ankistrodesmus falcatus was concerned in the metabolism of cell division.

宋鎬京,辛昌男 忠南大學校 環境問題硏究所 1985 環境硏究 Vol.3 No.1

The floristic composition and RA ordination, based on the data obtained from 150 nested quad-rats by releve method of Mueller- Dombois and Ellenberg, were applied to classify forest communti-ties in Mt. Gyeryong, and to investigate the relationships between species composition and sites. The investigation was done from June 1981 till May 1985. 1. The forest vegetation in Mt. Gyeryong was classified into Pinus Densiflora, Pinus densiflora-Quercus variabilis and Quercus mongolica communities according to the floristic composition, and it was subdivided into Pinus densiflora, Styrax japonica, Quercus variabilis, Carpinus laxiflora, Quer-cus mongolica, and Carpinus cordata forests according to the physignomy. It is peculiary significant that Quercus mongolica community was mainly distributed at the ridge, the high elevation and the steep slope areas of the mountain. The disribution of the leading dominant species in the tree layer showed a close relation with soil moisture gradient. For example, Quercus aliena, Platycarya strobilacea, Styrax japonica, and Zelkova serrata in the mesic area; Quercus mongolica, Fraxinus sieboldiana, and Lindera obtusiloba in xeric area. When the investigations were made starting from the Pinus densiflora community up to the Quercus monogolica community, a significant increase of total nitro- gen, organic matter content, available phoshorus, and cation exchange capacity in soil was shown. 2. The relationship between the distribustion of dominant species of forest vegetation and soil condition in Mt. Gyeryong was investigated by analyzing soil nutrition and moisture gradient. Carpinus cordata forest was distributed in the subserix and good nutrition area, Styrax japonica forest in the mesic and medium nutrition area, Pinus densiflora forest in the subserix and poor nutrition area, Quercus mongolica forest in the serix and relative good nutrition area, and Carpinus laxiflora and Quercus variabilis forest in the subserix and relative good nutrition area. 3. Based on the above classification, the vegetation map of Mt. Gyeryong was prepared in consideration of climate conditions, and the topography and distribution of soil. 4. The relative densities of an oak seedling of the Pinus densiflora community, the Pinus densiflora- Quercus variabilis community, and the Quercus mongolica community were 90%, 86%, and 63% respectively. And the relative density of a hornbeam seedling of the Quercus mongolica community was 29%. 5. According to the RA ordination, except particular terrain like rocky one, the major successional pathway of tree layer was from a pine community through an oak community to a mongolian oak community in the hilly zones and to a hornbeam community in the low zones. 6. According to the interspecific correlations, the tree layer was subdivided into Pinus densiflora group, Quercus mongolica group, and Styrax japonica group, and the shrub layer into Lespedza bicolor-Indigofera kirilowi group and Callicarpa japonica- Euonymus oxyphyllus group, and the herblayer into Arundinella hirta group, Disporum smilacinum group, and Ainsliaea acerifolia group. 7. In the whole mountains, ten dominant species of tree layer were found in the order of Pinus densiflora, Quercus mongolica, Quercus variabilis, Styrax japonica, Castanea crenata, Carpinus laxiflora, Quercus serrata, Styrax obassia, Zelkova serrata, and Prunus serrulata var. spontanea. The dominant species of shrub layer were Lespedeza maximowiczii, Quercus serrata, Stephanandra incisa, Fraxinus sieboldiana, Lindera obtusiloba, Weigela subsessilis, Quercus mongolica, Smilax china, Lespedeza bicolor, and Symplocos chinensis for. pilosa. The dominant species of herb layer were Spodiopogon cotulifer, Artemisia keiskeana, Disporum smilacinum, Carex okamotoi, Carex humilis, Festuca ovina, Smilax nipponica, Isodin inflexus, Oplismenus undulatifolius, and Viola albida.

Pollen morphology of Lilium 1ancifolium L. leichtlinii var, tigrinum and L, distichum was examined by the light microscopy in conjunction differences of pollen Character in Kwangnung, The pollen character of three species was similar except the grain size, The average polar axis and equatrial axis of L,lancifolium showed the highest values among three species and L.distichum was lowest. The differences of them in three species were significant judging from the F-test (p<0.05). And the differences in size of pollen grain in three species were significant (P<0.05). It was possible for grain size to classify the pollen of species of Lilium.

해바라기의 光合成能과 生産性의 變化에 關하여

辛昌男,金利鍾 충남대학교 자연과학연구소 1976 學術硏究誌 Vol.3 No.1

本 硏究는 growing season 中 해바라기 잎의 生長과 葉順에 따른 光合成能의 變化를 model 化하고 이에 따른 해바라기의 物質生産性의 變化를 調査하였다. 1. 單葉의 光合成能의 變化는 잎의 生長速度와 같이 한 個의 極大値를 갖는 曲線으로 表示되다. 2. 해바라기의 葉順에 따른 光合成能의 變化는 單葉의 生長에 依한 光合成能의 變化와 같다. 3. 光合成量의 變化는 Chang & Yoshida의 一般生長式에 適用되며, 어떤 地域이 選定되면 그 地域은 거의 一定한 條件下에 놓이므로 P=p(t)로 要約된다. 여기에 單葉과 葉順에 對한 光合成能의 實驗結果를 適用하면 p'(t)=-at²+bt+c (1) ◀원문참조▶ (1') 따라서 (1)을 積分하여 ◀원문참조▶ (2) 或은 (1‘)을 積分하여 ◀원문참조▶ (2') 를 얻을 수 있다. 여기서 P는 總光合成量, p'는 光合成能, Pas는 光合成量의 上寒値, a.b.c,d는 常數 k는 光合成量의 生長係數를 나타낸다. 4. 葉面積의 生長은 위로 올라갈수록 넓어져 最高에 達하고 다시 減少한다. 實驗終了時에 盆裁한 것에서 가장 넓은 잎은 80個의 잎 中에서 62번째의 잎으로 61,380㎟이었다. 群落에서 가장 넓은 잎은 76개의 잎 中에서 57번째의 잎으로 53,190㎟이었다. 5. 葉重의 生長은 頂端에 갈수록 增加하여 最高에 이르고 다시 減少한다. 實驗最終了時에 盆栽한 것에서 가장 乾量이 큰 것은 8개의 잎 中에서 68번째 잎으로 4.89g이었고, 群落ㅓ에서는 76個의 잎 中에서 60번째의 잎으로 3.91g이었다. 6. 葉重과 葉面積의 增加에 따라 光合成能이 增加하나 葉重과 葉面積의 關係는 반드시 一致하지는 않는다. 7. 主根과 側根의 季節에 따른 現存量의 變化는 地下로 갈수록 顯著히 減少한다. 8. 해바라기의 物質生産性은 日日生産性이 盆栽에서는 7月 31日에서 8月 15日 사이에 10.85g으로 가장많고, 群落에서는 8月 15日에서 8月 30日 사이에 6.93g으로 가장 많았다. 9. 해바라기의 生産構造는 줄기는 위로 갈수록 單位乾量이 減少하고, 盆栽한 個體에서의 葉量은 높이 175~250cm에서 가장 많다. 10. 鐘子는 盆栽한 것의 種子數가 1,243개이고, 1個의 平均 무게가 0.102g이었다. 群落을 이룬 것은 種子數가 1,056個이고 1個의 平均 무게가 0.075g이었다. 11. 해바라기 잎의 枯死는 6月 15日 以後부터 일어났으며, 最終試料에서 盆栽한 것은 37번째까지 枯死했고, 群落의 경우에는 40번째 잎까지 枯死하였다. This study involves an approach about the modeling of the changes of photosynthetic activity in the growth and order of the leaves of sunflower during the growing season. The change of photosynthetic activity of a leaf can be represented by the curve with a maximum value just as in the case of the growth rate of the leaf. The change of photosynthetic activity in the leaf order of the sunflower is the same as that in the growth of a leaf.
