이강세,현동윤,박문수,김선 군산대학교 기초과학연구소 2000 基礎科學硏究 Vol.15 No.-

We determined the most adapted area as measured leaf function and chlorophyⅡfluorescence with a long-term on leaflets of Kasiogalpi (Eleutherococcus senticosus Mas) plants grown in Iksan, Changge and Mt. Chiri. 1. In area of Iksan and Changge, during the day, rate of CO2 assimilation was highest at ante meridiem, and it was not coincide with transpiration. But transpiration was generally coincide with highest light intensity and leaf temperature. When compared CO2 assimilation at each area, Changge showed highly pronounced diurnal fluctuation throughout season, but Mt. Chiri remaining low level without obvious fluctuation during the day. 2. The time-course of PAR (photon active radiation) and leaf temperature at each area was observed differently. Among areas, it showed substantially higher at Iksan than at relatively high attitude area (Mt. Chiri). 3. ChlorophyⅡ fluorescence, i.e., Fo, Fm and Fv/Fm were not different in compared Iksan with Changge. But at Mt. Chiri, it was higher than at any other areas.

吳瀁鎬,李康世 群山大學校自然科學硏究所 1986 自然科學硏究 Vol.1 No.-

有用因子의 保存과 利用度의 提高라는 觀點에서 國內外 180種의 과맥品種에 대하여 特性調査를 실시한 결과 原産地와 穗型에 따라 形質의 變異가 현저하였다. 특히 稈長, 穗長, 芒長, 抽穗度, 穗密度 등의 形質에서 品種群間 差異가 뚜렷하였음에 반하여 小穗段數는 變異가 微微하였으며, 芒長, 穗密度는 雙峰曲線을 가진 變異를 나타내었다. 또한 形質間에 있어서도 原産地와 穗型이 다른 品種群間에 서로 다른 相關關係를 보여 각 形質別로 期待되는 品種의 探索에 많은 知見을 얻었으며 나아가 特徵있는 育種母材의 選拔이 可能하였다. From a viewpoint of both preservation of useful genes and reconsideration of their utilization, the examination into characters of 180 kinds of naked barley varieties within and outside Korea resulted in the conspicuous variation of characters according to source of varieties and ear-types. Especially, the differences between varietal groups in characters of culm length, spike length, awn length, flag leaf-spike distance, spike density, and the like, were distinct, while the variation in number of rachis was insignificant. And awn length and spike density showed a variation with bi-normal distribution curves. Also, the different correlations between varietal groups of different source of varieties and ear-types appeared in even characters, and much knowledge was obtained from the search of varieties expected according to individual characters, and furthermore the selection of characteristic parental sources for breeding was possible.

이강세,오윤섭 群山大學校基礎科學硏究所 1998 基礎科學硏究 Vol.13 No.-

땅콩의 결협율 향상과 화기내 Cytokinin함량과의 관계를 검토분석한 결과는 다음과 같다. 1. 화기의 착생위치별로는 1차분지에서는 저위분지, 자엽절 분지에서는 기부절(제1-2절)에서 Cytokinin함량이 높았다. 화기의 채취시기별 화기내 Cytokinin함량은 분지종류 및 분지위치에 관계없이 DAF 7, DAF 10, 개화당일의 順이었다. 2. 低位節(제1-2절) 절제시 頂部節(제5-6절) 화기내 Cytokinin함량은 DAF 7과 DAF 14구가 무절제구보다 각각 112, 337% 높았다. 3. 主莖 出液중 Cytokinin함량은 화기내 Cytokinin보다 월등히 높았다. 4. 자엽절분지에서 결협율은 화기내 Cytokinin 함량과 밀접한 관계를 보였다. Contents of cytokinin of cotyledon branch and first branch among primary branches were higher than those of other branches. Contents of cytokinin of basal part (first and second nod) of primary branches were higher than those of upper nod (fifth and sixth nod). Contents of cytokinin of floral instrument with days after flowering were high at DAF 7, DAF 14, DAF 0 orderly irrespective of kinds of branch and position of nod. Contents of cytokinin of upper nodal part with removing the lower nodal part (first-fourth nod) were high by 112-337% at DAF 7 and DAF 14 compared with those of the control plot. Contents of cytokinin of an extract from cutting site of main stem were much more than those of floral instruments. Pod-setting ratio of flowers versus flower position on the cotyledon branch was closely related with the cytokinin contents of floral instruments.

畓裏作 麥類 機械收穫方法 確立에 關한 硏究 : Ⅲ. 團地條件에 따른 콤바인 作業精度와 收穫粒의 品位에 關하여 Ⅲ. Combine Harvesting Workability and Grain Quality under Different Harvesting Field Conditions

李康世,朴文洙 群山大學校自然科學硏究所 1987 自然科學硏究 Vol.2 No.-

올밀의 栽培圃場에서 콤바인收穫當時의 栽培條件을 달리하여 作業能率, 損失量, 穀粒品位등을 檢討하였던바 그 結果를 要約하면 다음과 같다. 1. 콤바인을 利用할 경우 出穗後 44日頃이 收穫適期에 해당되나 乾燥劑를 處理하면 慣行區의 收穫適期(40日)까지 앞당길 수 있었다. 2. 콤바인收穫區는 慣行收穫區에 비하여 收穫作業時間이 85%절감되었으나 收穫損失率은 4.2%(26-31kg/10a)를 보여 4倍까지 增加되었다. 특히 雜草放任區와 아침刈取區에서 損失量이 현저하였다. 3. 콤바인收穫區는 慣行收穫區에 비하여 5%程度, 倒伏區, 아침刈取區, 乾燥劑處理區는 各各의 對照區에 비하여 2∼4% 減收되는 경향이었다. 4. 미탈부율은 콤바인 收穫區에서 2%미만을 보여 慣行收穫區의 5.7%보다 양호하였으며 특히 雜草放任區(3.8%)와 아침刈取區(4.5%)에서 높아 穀粒의 品位가 低下되었다. 5. 雜草放任區의 減收率은 12%로서 生育初期의 둑새풀(9%)과 生育後期의 갈퀴덩굴(3%)에 起因하는 것으로 분석되었다. This experiment was conducted to determine the effects of different harvesting field conditions on the working ability of Combine and the loss and quality of wheat grain. Harvesting working time by Combine required for only 15 percentage of conventional conduct, but grain loss marked 26-31 kg/10a and it was as much as forth times against conventional conduct. However grain yield by Combine harvesting only reduced by 5% as compared to conventional, but there was no statistical significant. And grain quality was good because the fine grain degree has over 98%.

땅콩의 無效開花를 抑制하여 精粒率이 높은 栽培法을 講究하기 위하여 C-MH을 開花後 24日, 28日, 31日에 500倍液, 1,000倍液, 1,500倍液으로 달리하여 處理한 試驗 結果는 다음과 같다. 1)主莖長은 無處理에 比하여 38∼44% 減少되었으나 分枝數는 處理時期, 濃度에 關係없이 變化가 거의 없었다. 2)處理後 28日의 開花抑制率은 500∼1,000倍液 處理時 29∼38%, 1,500倍液 處理時 22% 였다. 3)C-MH處理에 따른 完熟粒率(=精粒率)은 無處理區(56%)에 比하여 開花後 28日 處理時 55∼59%이고, 이중 1,000倍液 處理區에서 59%로서 3%가 向上되었다. 4)開花後 28日에 1,000∼1,500倍液 處理區와 開花後 31日에 1,000倍液 處理區의 收量이 無處理區와 對等하였다. C-MH(Cholinesalt of maleic hydrazide, 39%) has been applied on peanut(Arachis hypogaea L.) plant in 1994∼1995 at the time of 3 different times, 38 accumulative flowers(=24 days after flowering;DAF), 50 flowers(=23 DAF), 63 flowers(=31 DAF) and at the 3 different level of 500, 1,000, 1,500 double the solution. Main stem length was noticeably retarded by 38∼44% compared to that of control. Branch numbers were not changed at any treatment conditions. Ratio of flowering inhibition to control plot was 38% at the 500 double the solution and 22% at the 1,500 double the solution at the time of 50 accumulative flowers, respectively. Ratio of uniform matured seed was slightly enhanced by 3%. Namely, that of control plot was 55.6% and that of 1,000 double the solution at 50 accumulative flowers was 58.6%. Yield productivity of 1,000 double the solution at 50 accumulative flowers was increased by 7% compared to that of control(3.2MT/ha).

오양호,이강세 群山大學校基礎科學硏究所 1995 基礎科學硏究 Vol.10 No.-

쌀보리의 이삭에 관한 기초자료를 얻고자 우리나라에서 육성된 쌀보리의 품종을 공시하여 소수 위치에 따른 망의 길이와 무게, 입중등을 조사한 바 그 결과를 요약하면 다음과 같다. 1.이삭의 정단부로부터 3∼5번째 소수가 망장 및 망중의 평균치와 2∼4번째 소수가 입중의 평균치와 각각 일치하였다. 2.이삭의 기부로부터 3∼4번째 소수의 망이 가장 길고 무거웠으며 5∼6번째 소수의 입중이 가장 무거웠다. 3.측렬 소수는 중앙렬 소수에 비하여 망장은 13∼26%, 망중은 24∼41%, 입중은 18∼25% 적은 값을 보였다. Nami형 품종은 Uzu형 품종에 비하여 중앙렬과 측렬간 망장, 망중 차이가 적었다. 4.망중/망장 비로 볼때 Uzu형 품종은 Nami형 품종보다, 그리고 중앙렬은 측렬보다 망이 더 굵었다. 5.이삭을 3등분 하였을 때 망장, 망중은 하부와 중앙부간 차이가 없었으나 상부보다는 길고 무거웠다. 입중은 상부가 항상 가벼웠고 중앙부는 하부보다 무겁거나 같았다. 6.망중이 무거운 소수일수록 입중이 무거웠다. To obtain basic information for characteristics of naked barley cultivars, awn length and weight, kernel weight along spikelet positions of some cultivars bred in Korea were investigated. 1.Awn length and weight of third to fifth spikelet, and kernel weight of second of fourth spikelet from spike tip were not different from each mean value for tatal of spike. 2.From the spike base, awn of third to fourth spikelet was longest and heaviest, and kernel weight of fifth to sixth spikelet was heaviest. 3.Value for awn length, awn weight, and kernel weight of lateral row florets was lower 13 to 26%, 24 to 41%, and 18 to 25%, respectively than one for those of cental row floret. Difference for awn length and weight between central and lateral row in Nami type cultivars compared to Uzu type cultivars was small. 4.In the ratio of weight/length of awn, awn of Uzu type cultivars was thicker than that of Nami type cultivars, and awn of central row was thicker than those of lateral raws. 5.When one spike was divided into three parts, awn length and weight of low part were not different from those of central part, but were longer and heavier than those of upper part. The order of kernel weight was central≥low>upper part. 6.Kernel weight was linearly related to awn weight.
