감자育種의 基礎硏究 : II.Solanum tuberosum의 雄性不稔花의 花粉退化에 관하여 II.Pollen degeneration in male-sterile flower of Solanum tuberosum(cv.Shimabara)

金濟桓,金賢順 전북대학교 농업과학기술연구소 1980 農大論文集 Vol.11 No.-

Present experiment was investigated in order to make clear the historical mechanism of male-sterile potato. The result obtained were summarized as follows : 1. The formation of microspore of male-fertile flower is normal. 2. In male-sterile flower the tapetum hypertrophy proceeds noticeably from drad stage of microspore mother cell. 3. Tapetum tissue develops such hypertrophy that microspore of the male-sterile flower could not grow up fertile pollen and it become sterile-pollen.

陸稻品種間의 量的形質의 變異와 그의 相關 : I.湛水栽培下에서의 量的形質의 變異와 그의 相關 I.Variation and correlation of the quantitative characters under the submerged culture

金濟桓 전북대학교 농업과학기술연구소 1976 農大論文集 Vol.7 No.-

In order to investigate the variation of the quantitative characters and their correlations of 20varieties of upland rice, the rice was planted by the four replication randomized-block-design method and by the one-plant planting method in the experimental farm of Jeonbug national university on the 20th of June, 1975, and was harvested on the 22th of Oct., 1975. The author investigated the correlations of the qualitative characters shown. By analyzing the relationship of these characters to the yield, it has become easy to discover the high yield varieties. The results can be summarized as follows : 1. The factors that determined the yield of upland rice were not only the number of stems, the number of panicles, and the health of the rice plant but also the length of panicles and grain weight. 2. The longer the panicle was, the greater the number of grains. 3. There was a tendency of negative correlation between the number of stems or the number of panicles and grain weight. The more stems the variety had, the lighter its grain was. 4. It was found that there is little correlation between the number of grains and the yield in upland rice. 5. Katenwase, Kokukou, Nakabara, Housenjiyobouruchi, Seikokutaiou, ,and Rikutoukanto # 72 were found to be high-yield varieties.

日本民族主義의 成立에 관한 硏究 : 萌芽期에 있어서 列强과의 關係를 中心으로

金濟環 東亞大學校 1978 東亞論叢 Vol.15 No.1

The modern history of Japan is in accord with his nationalistic developmental process. When a concept of "nationalism" may be considered as a thought or movement of any ethmic group oriented toward preservation and development of their own nation against any other one, such a nationalism could be found, at every place, in every age. However, if we define "nationalism" as a collective consciousness or movement oriented toward a common goal of any national group, strictly speaking, reffered to the their sense of national identification, such a nationalism in Japan could be found in the end of the Shougunate. In the last years of eighteenth century, the Powers of the Britain, France, Russia and others had been sending the adventurers to the North pacific mostly for the purpose of getting the new resources and the commerce with Japan. These motions of the Western Powers had strained the relations of Japan to the west European world, and it resulted in enhancing a nationalist consciousness of the Japanese. Consequently, the rulers of Japan at that time, especially the warrior-class (the Samurais), gradually came to express great anxiety, about the fate of their country. This resulted in raising the reverence movement for the King, and it came to show an anti-western tendency named 'exclusion of foreigners.' Russia, whose advance toward the East Asia was aimed at obtaining his national interest through trade with Japan, had twice attacked Japan, in 1806 and 1807. Just then, such a movement arose. And in 1808 the Britain who, since the British-Dutch war in 1780∼83, had been advancing to the monopolized Dutch colonies, arrived after Dutch ships at the port Nagasaki in the Japanese Islands, and finally in 1824 the British whalers came close to and fired on the coast of Japan. These events caused the Shogunate government to strengthen the foreigners-exclusion policy further than ever before and even to issue ordinance an to attack and sent to the bottom all the strange foreign ships. On the one hand, the United States of America, who, in 1791, while engaged in the Kwang-tung trade, had already experienced the first entry of the two ships of his own into a port of Japan, came to attempt to open Japan to foreign intercourse since 1837. At last this attempt of America brought a success, in 1854, by the Marshal Perry who was entrusted with the important mission from the President. As the result of the event, Japan, entered into diplomatic relations with an Occidental nation, America, for the first time of his history. But, as the seclusionism to which the Britain and Russia had made Japan further adhere was broken up by America, Japan had to go through a severe reactions. The inequel trode treaties that Japan was subsequently forced to conclude with other Western Powers strongly caused the foreigners-exclusion movements as well as the reverence movements for the King. As a result, the Shogunate was faced with serious problem. It had to stop oppressing such movements and to alter its policy to compromise. In the process of the reverence movements spread throughout the whole country, encouraged by altered attitudes of the Shougunate, they tured to overthrowing movements of the Shougunate system. This trend required the strengthing of national power, and finally it resulted in establishment of a centralized powerful government. This was just the innovation of government, so-called 'Meiji-ishin.'

The tapetum is 2~3 layers of glandular tapetum, the cells of which frequently become 2-multinucleate, with occasional nuclear fusions. 5. The meiosis of the microspore is regular. 6. The microspore tetrads are tetrahedral type. 7. The microspores separated from microspore tetrad are foardripartition. 8. The quardripartitions becomes gradually round until flowering. 9.

마늘의 生長点培養에 관한 硏究 : II.Callus形成 및 組織學的 變化에 관하여 II.Investigation of Callus formation and histological changes

金濟桓,殷種旋 전북대학교 농업과학기술연구소 1981 農大論文集 Vol.12 No.-

In order to select the virus~free stock for the tissue culture of garlic, meristems were cultured in nine kinds of media. The formation of callus and the histological changes of meristem were examined. The media of Chapman, Steward and Hildebrandt were vigorous for the formation of callus tissue. The callus were observed to initiate from meristematic cells of growing point, vascular bundle system, parenchyma tissue of inner epidermis and cutting surface. Parenchyma tissue had the tendency of undergoing periclinal division at the initial stage of culture, but callus mass were formed by the disorderly division later. Some of the periclinally divided parenchyma cells became elongated during culture to diffrrentiated into tracheids.
