李鍾縕,愼英範,李恩鎬 영남대학교 자원문제연구소 1982 資源問題硏究 Vol.1 No.-

This study was conducted to determine the effect of exchangeable cations in apple orchard soil on occurrence of bitter pit in Golden Delicious fruits. Degree of bitter pit occurrence was compared with content of exchangeable cations such as Ca, Mg and K. Golden Delious fruits harvested from the experimental areas was stored for 75 days and during this storage period the occurrence of bitter pit was detected. The results obtained can be summerized as follows. The occurrence of bitter pit was closely related with content of exchangeable Ca in soil and it occured when exchangeable Ca content was lower than 70mg/100g. However, there was no relation with exchangeable K and N in soil. Even under higher content of exchangeable Ca, bitter pit occured when the ratio of Ca0/Mg0+K20 was lower than 2.5,specially with higher content of exchangeable Mg in soil. During this storage period, the higher % of bitter pit occurrence was observed inn Golden Delicious fruits collected from the experimental area where the higher degree of bitter pit was observed. The % of bitter pit occurrence increased as the storage period was prolonged. During the storage period for 45 days from 30 to 75 days after the storage begin, the occurrence of bitter pit increased 15% in healthy fruits. but 26% in Golden Delious fruits collected from the experimental area having 5% of bitter pit occurrence and 32% from 20% of bitter pit occurrence.

李鍾縕 慶北大學校 1979 論文集 Vol.28 No.-

By the most rapid changeable factors of Thecodiplosis japonensis and fire for the forest ecosystem in Korea changed vegetation structure and microclimate were investigated in the area Gachang: 1. All area investigated, in the course of succession, had not so much "treu" differential species, but noticed Pinus densiflora, Rhododendron mucronulatum, Lespedeza cyrtobotrya, Quercus serrata and new immigrated species were appeared as differential species in the area of fire damaged. 2. In the changed area by fire found much Geophyta and Therophyta. 3. Temperature differences in a day according to the height were 7.6℃ in the fire damaged and 5.4℃ in the Thecodiplosis japonensis damaged area at 13˚°p.m. and found little differences at surface and underground. 4. In the Thecodiplosis japonensis damaged area of relatively homogeneous stratified structure overground humidity and saturating deficiency were unnoticeable, but in the area of fire damaged noticeable differences.

李鍾縕,李恩鎬,愼英範 嶺南大學校附設 基礎科學硏究所 1981 基礎科學硏究 Vol.1 No.-

Coast forest vegetation of west side in Choongnam province was studied to explain the structure, quantity of vegetation and differential species for vegetational classification. 1. 5 observed areas were physiognomically devided. 2. QS between the areas were about 60, but were not similar cut-over area and mixed stand among them. 3. Major parts of life form spectrums were Macrophanerophyta and Geophyta. 4. Differential species of the areas were as follows; 1) Pinus densiflora-type: Lespedeza cyrtobotrya, Quercus acutissima, Festuca ovina, Peucedanum terebinthaceum, Aster scaber. 2) Mixed stand: Lespedeza thunbergii, Cocculus trilobus, Quercus aliena. 3) Hardwood stand: Juniperus rigida, Lespedeza cyrtobotrya, Spiraea prunifolia, Carex lanceolata. 4) Cut-over area: Lespedeza maximowiczii, Prunus sargentii, Vaccinium oldhami, Corylus heterophylla, Rhus trichocarpa, Styrax obassia, Viburnum erosum, Lindera obtusiloba, Zanthoxylum schinifolium, Stephanandra incisa, Aster scaber, Scutellaria indica, Polygonatum humile, Platanthera metabifolia, Melampyrum roseum, Vicia nipponica, Hemerocallis minor, Lysimachia barystachys. 5. Pinus densiflora, Quercus dentata, Quercus settata, Indigofera kirilowii, Rhododendron mucronulatum, Smilax china, Miscanthus sinensis, Arundinella hirta, Pteridium aquilinum might be included in higher rank as cheracter species.

李鐘縕,全在仁,申相千 嶺南大學校附設 基礎科學硏究所 1987 基礎科學硏究 Vol.7 No.-

最近에 歸化植物로 報告된 Lactuca serriola의 種組成, 種間 結合類型 및 群落形成 類型을 調査하였다. 10個의 全 地域(總 100個의 方形區)은 草本層이 90% 이상, 灌木層이 5% 이하였고, 喬木層이 전혀 나타나지 않았으며, Kummerowia stipulacea, Setaria viridis, Ambrosia artemisiifolia, Humulus japonicus, Bromus japonicus 등이 優占하고 있었고, 土壤의 pH, 鹽基飽和度는 濕原地域이나 山地보다 높았으나, 現地含水能, 腐植質 含量은 낮게 나타나는 典型的인 空間地 植生으로 遷移初期段階의 植物相을 형성하고 있었다. 出現種들은 Kummerowia stipulacea, Calystegia hederacea, Ambrosia artemisiifolia 등이 優占하는 集團과 Humulus japonicus, Bromus japonicus, Agropyron ciliare 등이 優占하는 集團을 형성하였다. 各 地域間의 植生은 DIF 0.5의 수준에서 4個의 類型으로 區分되었으며, 이와같이 높은 DIF 값에서 4個의 類型으로 區分되는 것으로 보아 空閑地 植生에서 아직 Lactuca serriola 特有의 群落은 형성되지 않은 것으로 나타났다. A study was made on the species compositions, interspecific associations and community forming patterns of recently immigrated plant, Lactuca serriola. Ten selected sites (total 100 quadrats) showed typical ruderal vegetation of early successional stage: herbaceous layer was found more than 90% of the each quadrat, whereas shrub layer was found less than 5% of the each quadrat, and no tree layer was found; dominant species were Kummerowia stipulacea, Setaria viridis, Ambrosia artemisii-folia, Hummlus japonicus, Bromus japonicus etc.; pH and percent base saturation of the soil(site I. IV. V) were relatively high but field moisture capacity and humus content of the soil were low. The 10 selected sites can be identified as two different groups of species; one was dominated by Kummerowia stipulacea, Setaria viridis, Ambrosia artemisiifolia etc, and the other was dominated by Humulus japonicus, Bromus japonicus, Agropyron ciliare etc. The investigated sites were divided into 4 patterns based on the vegetaion of the high DIF level, 0.5. The presence of many patterns despite such a high level of DIF indicated that characteristic community of Lactuca serriola was not formed yet.

本 實驗은 우리나라의 霙芝 버섯의 포트 栽培에서 發生하는 푸른곰팡이병의 原因茵의 규명과 그 防除法을 확립하고져 실시하였다. 實驗結果는 곰팡이 3種과 細茵 3種의 分離되었다. 이중 푸른곰팡이 症狀의 原因茵은 Trichoderma Roningi, T. lignorum, 未同定 1種임이 확인되었고, 발생빈도는 각각 60%, 30%, 10%이었다. T. lignorum은PDA 배지 Waksman's and Richard's solution에서 생장이 좋았고, 중성-알카리성에서는 生長이 不良한 반면 산성에서 生長이 좋았으며, 최적산도는 pH4였다. Trichoderma spp. 는 70℃에서 60分間, 80℃에서 30分間 열처리하므로서 완전히 사멸되었다. Three species of Trichoderma causing green mildew of Ganoderma lucidum were isolated from 6 spots of G. lucidum growing areas in Dae Gu. These are T. roningi, T. lignorum, and an unidentified species, and their frequencies of occurrence are 60%, 30%, and 10%, respectively. All of these species grew well in potato dextrose, Waksman's and Richard's solution, and preferred acidec(pH4.0) to neutral condditions. T. lignorum was killed when exposed for either 60minutes at 70℃, or for 30minutes at 80℃.

RI, CHONG UN 韓國自然史博物學會 1976 生物과 自然 Vol.6 No.-

Three different and intensive used meadows (Parsch, Moos and Koppl) were selected to reseach the composition of species. Area Parsch at a fresh lowland shows typical Arrhenatheretum of middle Europe and at the wet, intensive manured and basic marshy area of Moos indicates the variant of Arrhenatheretum with a few of species. But Koppl lies at the poor and acid landing area and shows Gentiano-Molinietum.

Ri, Chong Un,Kim, Yung Ho,Hong, Sung Cheon 慶北大學校 1977 論文集 Vol.24 No.-

迎日地區 砂防造林地帶의 植物社會學的 種組成과 그 問題點을 觀察하기 위하여 砂防造林地帶에 10개의 方形區, 비교적 自然狀態로 保存 되었다고 생각되는 地域에 10개의 方形區, 도합 20개의 方形區를 外觀上 均一한 地域에서 選定하여 圖表分析方法으로 시도하였다. 全觀察地域의 植生分類學的 特性은 Pinetea Thunbergii로 생각되나 砂防造林地域엔 種助成이 단순하여 주로 Alnus와 Pinus로 構成되어 있다. Alnus의 短命性과 林內에서 天然更新의 어려움 등과 Pinus densiflora의 솔잎혹파리 被害등을 勘案하면 海岸地帶엔 Pinus Thunbergii와 Celtis의 混淆林, 內陸地方에는 Pinus rigida와 Quercus의 混淆林을 造成 함이 바람직하다.

옥수수의 바이러스병에 관한 연구 : (1)Rice Black-streaked Dwarf Virus의 形狀과 細胞內出現 (1)Morphology and Intracellular Appearance of Rice Black-streaked Dwarf Virus

張茂雄,李鍾縕 영남대학교 자원문제연구소 1987 資源問題硏究 Vol.6 No.-

Dip preparations obtained by a modified direct negative staining method revealed both complete virus particles of 80-90nm and incomplete virus particles of 7O-74nm in diameter. Complete particles correspond to the large particles that appeared in the infected cell cytoplasm outside of the viroplasm and in the vacuoles. The large particles probably represent the complete particles of rice black-streaked dwarf virus(RBSDV) and the out coat may be easily removed by phosphotungsteic acid staining. All the features associated with RBSDA infection in maize neoplastic cells, ie. viroplasm, tubular structure and virus particles, were well preserved and easily recognizable in ultrathin section preparations. Large particles 70nm in diameter were free or aligned in tubular arrangement in the cytoplasm and vacuole. All these particles had an inner darken core and an outer lighter coat(complete particles), small particles 50nm in diameter, embadded in the viroplasm, seemed to lack an outer coat (incomplete particles). In the diseased maize leaves, the virus was restricted to the vascular bundle and bundle sheath cells.
