Ankistrodesmus falcatus의 대사과정중 alkaline phosphatase의 역할에 관하여

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.

辛昌男,李深信 충남대학교 자연과학연구소 1982 忠南科學硏究誌 Vol.9 No.1

Palynalogical characteristics of Pinus rigittaeda were observed under the scanning electron microscope, hybrids of Pinus taeda and Pinus rigida. The density and size of chamber cap in the surface of Pinus rigittaeda were difference of Pinus rigida and Pinustaeda, but the size and pattern of pollen grain body and air bladder were similar. However, the pattern of chamber cap of pinus rigittaeda was similar to Pinus taeda, and the other characteristics were different.

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.

辛昌男 충남대학교 자연과학연구소 1978 學術硏究誌 Vol.5 No.2

Pollen morphology of easter lily was examined by light microscopy in conjunction with differences of size in three area-Ulsan, Daejeon and Kwangnung. 1) Polar axis of pollen is from 22μ to 34 u and equatorial axis from 15μ to 22μ. 2) The average polar axis and equatorial axis in Daejeon showed the lowest values of three area and Kwangnung is the highest values. The differences of those in three area was significant judging from the F-test (P>0.05). 3) P/E ratio is from 1.40 to 1.46 and the shape of pollen is prolate.

辛昌男,宋鎬京,朴鍾聲 忠南大學校 環境問題硏究所 1983 環境硏究 Vol.1 No.2

In order to determine the characteristics of soil in Mt. Gyeryong, the content of primary minerals and chemical and physical properties of forest soil were analyzed. The parent rock of forest soil were consisted of pink feldspar granite and gneissose granite. The weathered parent rock contained about 64% of plagioclase and quartz. The content of available phosphorus of soil resulted from weathering process of pink feldspar granite was higher than that of the gneissose granite soil. But the contents of K and of the latter were higher than those of the former. Both types of soil texture were mainly loam and clay loam The differences of chemical soil properties between Pinetum consociation and Quercetum consociation were as follows:the contents of the organic matter, total exchangeable bases, NO^-_3-N and NH^+_4-N of Quercetum consociation were higher than as compared to those Pinetum consociation in the pink feldspar granite region, the contents of total nitrogen, available phosphorus, total exchangeable bases, Mg^++ and NO^-_3-N of Quercetum consociation were higher than as compared to those of Pinetum consociation in the gneissose granite region.

3 species of Pinus in Korea, P. densiflora, P. rigida, P. koraiensis, were classified by polynological studies and TLC analysis of the free amino acids in pollen. The shapes of pollen grain are similar in 3 species. P. densiflora showed some differences in the size of pollen grain and in the number, the pattern, the angle of attachment and the size of air bladder with other 2 species (p<0.05). The cell wall thickness and the type of germ furrow surface of P. koraiensis are different from those of P. densiflora and P. rigida (p<0.05). Serine, glutamic acid, alanine, valine and histidine were detected in the pollen of P.densiflora and P. rigida, but not in that of P. koraiensis.

The research of relationship between the diameter of germinal furrow of Pinus densiflora pollen and the soil water content was carried out from April to May in the pine forest of Daejeon, Seoul and Mt, Chiak, The pollen morphology of Pinus densiflora in three area was similar except the diameter of germinal furrow. And the average diameter of germinal furrow in Daejeon showed the lowest values of three area and Seoul was the highest values. The differences of those in three area was significant judging from the F-test ( P<0.05). The correlation coefficients between the diameter of germinal furrow and the soil water content in three area were significant judging from the t-test ( P<0.05 ).
