劉在殷 명지대학교 1979 明大論文集 Vol.12 No.-

The convenient method in storage of chestnuts has been studied to use easily for the producers and the consumers. In this paper the protected chestnuts which stored underground were tested on the effective method of the long-term storage on a ground of their species, kinds of treatment and terms of treatment. The results obtained from the above methods are summarized as follows: 1. All the species can be stored for 10 months but changed slightly in qualities. 2. The effects of storage are very significant by their species, kinds of treatment and terms of treatment, respectively. 3. The chestnuts which dried in the shade for 1 and 3 day’s have been storaged with the best condition. 4. The control of germination during the long-term storage is not discussed in this paper.

금번 필자는 1987년 7월 5일부터 12일까지 8일간과 1989년 9월 11일부터 17일까지 7일간 총 15일 동안에 속리산 국립공원 일대의 자원식물 분포상을 조사하여 다음과 같은 결과를 얻을 수 있었다. 금번 조사기간 동안에 확인된 속리산 지역의 자원식물은 총 120과 369속 516종 1아종 88변종 및 7품종의 612종류였다. 이중에는 74종류의 식재 및 재배종이 포함된다. 속리산 지역에서 가장 흔히 볼수 있는 상층목으로는 소나무, 신갈나무, 졸참나무,서나무 등이고 하층목으로는 당단풍,쇠물푸레,쪽동백,생강나무 등이 주종을 이루고 있다. 남방계 식물인 노각나무는 이곳이 북한계가 아닌가 생각되며, 회화나무가 자생하고 있는 것을 확인할 수 있었던 것도 하나의 의미 있는 일이다. The distribution of resources flora in Mt. Sokri had been studied by releve method from July 5 to July 12, 1987 and from Sep. 11 to Sep 17, 1989.171 places with square (15m × 15m) were selected for exact survey and all the species which were present in the area were recorded. The results obtained can be summarized s follows; 612 taxa of vascular plants weredistributed in surveyed area of Mt. Sokri, which included 120 families, 369 genera, 516 species, 1 subspecies, 88 varieties and 7 forma. Among them, 74 species which had been cultivated or planted were also included. The upper layer plants was mostly occupied by Pinus densiflora, Quercus mongolica, Quercus serrata, Quercus variabilis and Carpinus laxiflora. In other hand, Acer pseudo-sieboldianum, Fraxinus sieboldiana, Styrax obassia, and Lindera obtusiloba were main species which composed of lower layer plants in Mt. Sokri. It was implicated that Mt. Sokri is the Northem limit of Natural habitats of Sophora japonica in Mt. Sokri in spite that they are usually occurring in cultivated area or field.

智異山 西部地域의 참나무類 分布에 關한 生態相

金智文,權琦遠,兪在殷 忠南大學校 環境問題硏究所 1986 環境硏究 Vol.4 No.2

Some ecological physiognomies related to the distribution of Quercus serrata and Q. mongolica as well as Carpinus laxiflora were investigated in the two valleys of Hwaumsa-Nogodan and Piagol-Yimgulryong in Mt. Jiri. For the purpose of the community analysis of the tree species, ten subplots of 10m x 10m quadrat were sampled in each of main plots partitioned into 4 or 5 sections along the altitude by valley. Even if being a little different by plot or by valley studied, the leading dominant tree species were analyzed to be C. laxiflora, Q. serrata and Q. mongolica, and the sub-dominant tree species to be Styrax japonica, S. obassia, Stewartia koreana and Acer pseudo-sieboldianum v. koreanum, etc. over all the area studied. But other Quercus species and Pinus densiflora seemed to be minor species in all the area ezcept for some quadrats of lower parts of the valleys. The importance values of C. laxiflora were estimated to be the highest on the altitude of about 1,000m and to be the lowest on the upper ridge and top in H-N valley, but to be the highest on the foot stand in P-Y valley. The values of Q. serrata have changed irregularly along the altitude in H-N valley and seemed to be a little high on the mid parts of the slope in P-Y valley. But the values of Q. mongolica have increased constantly with the ascent of altitude and so have exhibited the highest on the ridges exclusively in the two valleys, All the relative values have varied extensively among the subplots in the same plot, and the C.V. values calculated by plot have also exhibited a great deal of differences of 32-191% in R.D., 38-229% in R.C., and 38-206% in I.V. by species and by altitude. The relative values of R.D., R.F., R.C., and I.V. following the ecological successional stages based on gradient of altitude, have been fluctuated with similar patterns in C. laxiflora and Q. serrata, but with inverse patterns in the former two species and Q. mongolica. The dispersion patterns of the three species based on Morisita's index seemed to be random or contagious dispersions having the indices of 1.001-3.333 over all the plots studied. The relative densities following the size class of D.B.H. were estimated to be a little high in the mid of the size classes over all the plots and valleys in Q. serrata, but to be significantly high in the small of the size class in Q. mongolica. The four kinds of tree form indices have changed irregularly by kind of index, by species, and by altitude.

Streptomyces coelicolor에서의 이차대사산물 생산조절

홍순광,유재은 명지대학교 자연과학연구소 1996 자연과학논문집 Vol.13 No.-

방선균의 이차대사산물 생산 및 세포분화의 연구대상으로 가장 많이 연구되고 있는 Streptomyces coelicolor에서, actinorhodin 및 undecylprodigiosin과 같은 이차대사산물 생산을 전사단계에서 positive하게 조절하는 global 한 조절유전자 AfsR을 클로닝하여, 이가 코드하는 단백질 AfsR의 기능을 조사하였다 AfsR 단백질은 세포내에 존재하는 인산화효소(kinase)에 의하여 인산화된으로서 활성화되어 이차대사 생산의 조절을 담당하고 있는 것으로 판단된다. 이와같은 AfsR 단백질의 인산화 잔기의 정체를 규명하기 위하여, 인산화된 AfsR 단백질의 여러조건에서의 안정성 및 단백질인산화효소 저해제에 의한 효과를 조사하여 보았다. 그 결과 AfsR 단백질의 인산화 잔기는 산, 알칼리, hydoxylamine, pyridine 등의 처리에 비교적 높은 안정성을 보였고, 많은 종류의 인산화효소 저해제의 처리 결과, 진핵생물의 protein kinase C 계열과 유사한 인산화 단백질임이 밝혀졌다. Streptomyces coelicolor is the best understood strain for the secondary-metabolits formation and cell differentiation among the Streptomyces. The afsR gene hed been cloned as a positive regulatory gene for the production of the secondary metabolites such as actinorhodin and undecylprodigiosin from Streptomyces coelicolor A3(2). The AfsR protein can be phosphorylated by a certain kinase (AfsK) which is located on the cell membrane and the phospho-relay system between the AfsR and AfsK is similar with the typical eukaryotic signal transduction system, The phosphorylated residues of the AfsR was very stable in extreme pH and solvent conditions. The protein kinase inhibitors, staurosporine and K-252a, showed severe inhibitory effect for the phophorylation of the AfsR protein and it was concluded the AfsR/AfsK phospho-relay system is similar with the eukaryotic protein kinase C family.

버드나무과 종자의 활력검정

유재은 명지대학교 자연과학연구소 1997 자연과학논문집 Vol.16 No.-

은사시나무(Populus tomentiglandulosa), 사시나무 (Populus davidiana), 왕버들 (Salix glandulosa) 및 버드나무 (Salix koreensis) 종자의 활력기간을 검정하기 위하여 1997년 5월 8일, 1997년 5월 10일, 및 1997년 5월 20일에 이들의 완숙된 종자를 각각 채취한 후 그 다음날부터 발아시험을 통하여 활력을 검정한 바 다음과 같은 결과를 얻을 수 있었다. ① 버드나무 종자는 완숙된 종자를 채취하여 17-28℃가 유지되는 온실안에서 5일만에, 왕버들 종자는 6일만에, 은사시나무 종자는 7일만에, 사시나무 종자는 8일만에 모든 종자가 활력을 잃고 죽는다는 것을 알았다. ② 이들은 종자를 채취하는 즉시 파종하는 것이 발아율을 높이는데 효과적이라는 것을 알 수 있었으며, 파종 후 3-4일 이내에 대부분의 종자들이 발아되는 속성발아 종자임을 알 수 있었다. ③ 이들의 자연분포 밀도는 종자가 완숙되어 비산되는 기간동안의 날씨상태가 중요한 요인으로 작용하지 않나 생각된다. The viability test of Populus tomentiglandulosa, Populus davidiana, Salix glandulosa and Salix koreensis was carried out. All the seeds were collected from May 10 to May 20, 1997 and they were used for the viability test from the next day after collection. When the germination test was performed with the seeds which had been stored in green house with a temperature range of 17 ~ 28℃, complete loss of germination of Salix koreensis, Salix glandulosa, Populus tomentigrandulosa and Populus davidiana could be observed from the seeds which had been stored for 5, 6, 7 and 8 days, respectively. Therefore, it was concluded that the seeds of Salicaceae spp. tested should sowed as soon as possible after seed collection to increase their germination percentage and should be classified as rapid gennination seeds which can be germinated within 3 to 4 days after sowing. The atmospheric condition during the seed-maturing and seed-spreading period may affect severely on the natural distribution density of Salicaceae spp.
