新開墾地이 大豆에 대한 溶成燐肥 增施에 따른 加里施用의 效果

金鎭淇,黃南悅 全北大學校 1983 論文集 Vol.25 No.-

野山新開墾地土壤松汀統에서 光敎를 供時하여 溶成燐肥增施에 따른 加里增施效果에 關한 試驗結果를 要約하면 다음과 같다. 1. 收量에서 燐酸吸收係數 5% 調節施用區에서는 C.E.C. 5%의 加里施用區에서 最高收量 252㎏/10a, 燐酸吸收係數 10% 調節施用區에서는 C.E.C. 10%의 加里施用區에서 最高收量 282㎏/10a을 각각 얻었다. 2. 加里施用量과 收量間의 相關에서는 燐酸 48㎏/10a 施用時 加里 19㎏/10a 水準에서 最高收量을 얻을 수 있는 相關을 보였다. 3. 溶成燐肥增加와 함께 加里를 增施할 때 收量이 계속 增大되지 않았으며 이는 溶燐中의 Ca와 Mg의 增施와 더불어 加里가 多量施用됨으로써 鹽類가 蓄積되어 生理的障碍에 依한 것으로 思料된다. 4. 最高收量을 얻을 수 있는 加里活性度 (K/ √Ca+Mg)는 0.144로써 統計的인 有意性이 認定되었다. This experiment was carried out to study the effect of potassium application with fused phosphate to newly reclaimed soil (Song jeong Series) on soybean. The results are summarized as follows. 1. 5% phosphate absorption coefficient(P.A.C) with 5% cation exchange capacity(C.E.C) and 10% P.A.C. with 10% C.E.C. showed maximum yields being 10% and 19% increase in yield than non-treatment respectively. 2. Application of 19㎏/10a potassium with 48㎏/10a phosphate and 25㎏/10a potassium with 101㎏/10a phosphate could show highest soybean yields on newly reclaimed soil through regression equation of phosphate and potassium. 3. Increased fused phosphate and potassium applied to the reclaimed soil were not followed with increased yield in parallel presumably on account of salt injury of fused phosphate and potash. 4. Between yield and potassium were high correlation and the maximum yield coincided with 0.144 potassium activity degree(K/ √Ca+Mg).

種子의 非正常發芽에 關한 硏究 : 2. 大麥 種子의 非正常 發芽에 關한 硏究 2. A Study on the abnormal seedlings occurred in some barely (Hardeum vulgare L.) seeds

金鎭淇,金丁坤 全北大學校 1984 論文集 Vol.26 No.-

The present study was aimed to check types of morphologically abnormal seedlings of barley (Hordeum vl\ulgare L.) seeds occurring in laboratory tests. 13 barley cultivars were collected and tested for abnormal seedling occurrence. On average, 25% of abnormal seedings were found. The abnormal seedling percnntage was comparde sith other vigour indices and there were close correlationships among them. Through the experiment, most frequently found catergory of abnormality was both plumular and root system abnormal which occupied more than 50% of the total abnormal seedlings, then plumular abnormality, followde by root system abnormality. Overall more than sixty possible abnormal seedling types were observed. The abnormalities most frequently found were in the class of deformed or unbalanced seeding, for example short or severly short, then in damaged and decayed.

벼 耐旱性에 관한 硏究 : Ⅰ. Sucrose 濃度가 벼 品種의 發芽率에 미치는 影響 Ⅰ. Effect of sucrose concentraction on germination of some rice varieties

金鎭淇 全北大學校 1977 論文集 Vol.19 No.-

To find a criterion of drought resistance in rice, some rice cultivars (Oryza sativa L.) were checked on their percentage germination in various sucrose solutions of from 0.2M to 1.0M. No significant difference in percentage germination was observed except in 1.0M concentration and the results were not matched with those of the field tests at IRRI. Further studies are needed to compare this method with other measuring methods of drought resistance.

옥수수 播種期와 地上部形質에 관한 硏究

金鎭淇,崔京求,白南赫,陳星桂 全北大學校 1982 論文集 Vol.24 No.-

全北 平野地인 裡里地方에서 옥수수의 播種期와 地上部生育 및 種實收量과의 관계를 調査하여 다음과 같은 결과를 얻었다. 1. 播種期의 早晩이 莖葉의 生育 및 種實收量에 크게 영향을 끼치며 播種이 늦어질수록 出雄, 出絲, 生育日數가 짧아지고 地上部生育은 떨어지는 경향이다. 2. 莖葉生育은 4月 20日 播種을 基點으로, 種實收量은 5月 5日 播種을 基點으로 各各 減少되었다. 3. 地上部諸形質과 種實收量간에는 高度의 正의 相關이 인정되며 種實增收를 위하여는 莖葉生育은 크게 할 필요가 있다. Some results were gained through the experiment that was carried out with a single cross cultivar, Suweon 19, of maize (Zea mays L.) in Iri, the Jeonbug plain area, in 1980, to check relationships between growth characters at different sowing dates. 1. The foliage growth and grain yield were greatly influenced with planting season. The number of days to tasseling, silking, or maturing shortened and the growth of maize decreased as sowing was delayed. 2. The threshold sowing date for foliage production seemed to be April 20 and that for grain yield, May 5. 3. Highly significant positive correlation existed between vegetative growth and grain yield. This may mean that increasing vegetative growth is prerequisite to better grain yield.

뉴질랜드의 종자품질관리체계와 향후 우리나라의 품질관리 개선 방향

김진기,유남희,나의식 한국국제농업개발학회 2001 韓國國際農業開發學會誌 Vol.13 No.4

뉴질랜드의 종자산업은 종자개량, 품종보호, 종자생산, 종자검사, 종자보증 및 종자교역 등 여러분야의 연구와 실무를 통하여 종자품질관리에 선구적 입장을 유지하여 왔으며 신품종의 개발과 합리적인 증식 및 관리체계를 통하여 양질의 종자공급능력을 발전시켜 왔다. 1970 년대 이전까지는 품종개량 및 종자품질관리는 정부주도로 이루어졌으나 현재는 정부가 직접적인 관여에서 점차 간접적인 위임형태로 바꾸어 종자품질관리 관련 업무 일부만 남기고 모두 민영화가 추진되었다. 위임받은 업무에 대한 책임은 위임받은 조직이 지며 정부는 품질관리 체계를 정기적으로 감독하고 감시하는 자세로 전환하였다. 이와 같은 변화에 따라 종자품질관리체계의 하부조직은 대부분 독립적인 예산체계를 구축하였고 업무도 좀 더 독립성을 갖게 되는 효과를 보았다. 그러나 계속적인 정부 지원의 절감과 새로운 조직의 지나친 상업적 운영은 전문인력이 점차적인 감소와 연구개발활동의 축소라는 부작용도 있다. 우리나라의 종자산업발전을 위하여 공공기관이나 민간종묘회사 어느 쪽이든 품종개량과 종자품질관리활동이 활발하게 이루어져야 할 것임은 말할 것도 없다. 그러나 앞으로 국내 종자시장의 변화나 재정적인 이유로 품종개량과 종자품질관리체계에 어떤 개선이 요구된다면 뉴질랜드가 재정적인 동기에서 도출하였던 공공기관의 기능과 역할의 분담조정, 인력의 조직화와 민간종묘회사의 참여방식 및 종자의 상품화 체계구축 등 선험적 체계가 다소라도 참고가 되지 않을까 생각된다. New Zealand has developed a very efficient seed quality control scheme. In New Zealand, cultivars are now developed under contract to the CDMU(Cultivar Development and Maintenance Unit) of AgResearch(NZ Pastoral Agriculture Research Institute Limited). MAF (Ministry of Agriculture and Forestry) is empowered to provide seed certification services, and the scheme is administered by MAF Quality Management using procedures that are in accordance with OECD standards. New Zealand has no seed laws and participation in the seed production industry is entirely voluntary. although participants must adhere strictly to the rules and procedures involved. National Seed Laboratory (NSL) has played a central role in prividing seed quality assessment. Recently all sectors of the seed industry in New Zealand have been reformed and become more commercialized with users-pay policy. The services have been affected by moves to reduce government involvement in its affair and to eliminate government subsidies. However, this has led to reduction of research activities and personnel in seed technology. The future directions of seed quality control system in Korea could refer to New Zealand scheme.

黃鍾圭,金鎭淇,崔京求 全北大學校 1976 論文集 Vol.18 No.-

This investigation was aimed to clarify the mutual relationship between 54 major rice varieties bred in Korea or introduced from Japan. The coefficient of relationship was computed by Sakai's method and the results are as follows; 1. The 54 major varieties are origined from 28 ancestor varieties composing of 23 varieties from Japan, three from China, one from Philippine and one from Indonesia. Out of ancestors Aikoku and Asahi, both from Japan, are most closely related to the major varieties. 2. The lately bred varieties have much more ancestors than the earlier ones. For example, newly bred varieties Mangyeong and Akibare both have 12 ancestors, while earlier bred variety, Pungog has only one ancestor. 3. The 54 major varieties are related to each other by 90 percent of the total 1431 combinations, out of which 70 percentage have the coefficient of relationship from 0.0001 to 0.3.

人蔘의 育種 및 栽培年限 短縮에 關한 基礎硏究 : 第1報 新芽의 體眠打破에 미치는 植物生長調節物質의 影響 Effect of some growth regulators on the dormancy breaking of new buds

崔京求,金鎭淇,黃種奎 全北大學校 1978 論文集 Vol.20 No.-

This study was carried out to investigate the effect of some growth regulators i.e., gibberellic acid (GA), benzyladenine (BA) and abscisic acid (ABA) on the dormancy breaking of new buds in 2 year-old Ginseng plants. Materials were sampled in the middle of October and their dormancy was checked under the favorable conditions for germination of bud for a month. They were treated for 24 hours with the following growth regulators; (1) GA, BA and ABA at the concentrations of 50 and 100 ppm, and (2) the combination of GA and BA, GA and ABA, and BA and ABA at the concentrations of 50 ppm, respectively. It was found that the application of GA was effective in dormancy breaking of new buds and seemed to elongate stem, flower stalk and petiole but degenerated the majority of flower stalk in the early stage and also accelerated the formation of the adventitious root. By the application of GA, poor development of color was observed in leaf and stem in the early stage. The leaf began to regain green color with leaf maturation but the stem did not gain purple color. The applications of BA and ABA combined with GA showed almost the same effect in dormacy breaking as GA application. In these cases color development of stem and leaf was good cmpared with that of GA application. Even with some side-effects such as elongation and poor color development of stem and leaf, GA might be applied for dormancy breaking of new buds substituting for the low temperature in winter.

This study was conducted to investigate optimum planting date and pinching times on the growth and flowering of garden chrysanthemum(Dendranthema grandiflorum Ramat.). 3 lines of garden mums were planted on May 16, June 13 and July 11 respectively. As planting date was delayed, all the 3 lines' plant height and plant width was reduced. 09-19-49 line got the biggest plant height and width, followed by 09-11-37 line. And 08-166-02 line was the smallest. In different planting times, the experiment group of May 16 and June 13 got the biggest plant height, plant width and stem diameter. However, in the experiment group of May 16, most of the plants got flattened. The experiment group of June 13 got the best ornamental value, and the ornamental value was reduced in the experiment group of July 11 by the short vegetative growth. 09-19-49 line got the most flowers, while in different planting time, the experiment group of May 16 got the most flowers. 09-11-37 line got the biggest flower diameter. 09-11-37 line and 09-09-51 line were planted in the containers on the rooftop. Each groups were pinched by 1, 2 and 3 times on July 2, July 26 and Aug 16 respectively. There was no effect on plant height, plant width, and stem diameter of 09-09-51 line and 09-11-37 line between 1-time-pinching group and 2-time-pinching group. But 3-time-pinching group was reduced. There was no significance in flower diameter of these two lines but the number of flowers was reduced by more pinching times. Therefore, in this experiment, the groups which were planted on June 13 got the best ornamental value and the recommended planting time is in the middle of June. Furthermore, 2 times of pinching was recommended.

The neoplastic variant of calcifying odontogenic cyst has various designation, and its malignant counterpart has been reported as aggressive epithelial ghost cell tumor or odontogenic ghost cell carcinoma. Odontogenic ghost cell carcinoma(OGCC) is a rare carcinoma first documented in 1985. It is composed of varying sized islands of anucleated cells with homogenous, pale eosinophilic cytoplasm, so called ghost cells, were admixed with nucleated cells. We report a case of maxillary OGCC developed from odontogenic epithelial tumor in a 25-year-old man with literature review.
