主要國의 農業協同組合 發展過程

김지영 順天大學校 農業科學硏究所 1995 農業科學硏究 Vol.9 No.-

Generally speaking, the cooperative movement in the developed countries sprang up from the action of the economically weak people who wanted to improve their economic and social status during the rapid development of the capitalist economic system. Therefore, this movement was not aimed at capitalist pursuit of profits, but sprang up spontaneously for the purpose of promoting the advantage of a large-scale management and of realizing such ideals as liberty, equality, and other democratic values. While being introduced to every country of the world, such a cooperative movement, however, has not always been developed in the same form or type. In countries where the cooperative movement was unfolded in parallel with the development of capitalism, the consumer cooperative movement was domination, while in developing nations where the development of capitalism was lagging, but the agricultural cooperative movement was given priority.

UR以後의 農業政策方向

김형용 順天大學校 農業科學硏究所 1991 農業科學硏究 Vol.5 No.-

This study is aimed to propose the direction of Korean agricultural policy after Uruguay Round. The goals and contents of this study can be summarized as follows. On the premise that Korean agricultural industry, which has weak foundation of production, can not avoid the open-door policy, and foreign agricultural products make inroad into the domestic agricultural market, it is needed that new position of Korean agricultural industry, which can cope with Uruguay Round and meet new international order of agricultural industry, must be established as soon as possible. This study collectively analyse the direct and indirect effects of the open-door policy in agricultural industry on the domestic agricultural industry, and how to overcome and deal with the impacts caused by removal of the import restrictions in agricultural product.

보리의 飼料化를 위해서 登熟中期에 식물체를 家畜에 粗飼料로 給與하기에 적당한 總體型보리(Whole crop forage)로 까락이 없고 生體重이 큰 草型이 필요한데, 芒長 同質遺傳系(長芒,無芒)를 選拔하여 旱魃條件下에서 두 系統의 光合成能 및 主要 形質의 變異性을 조사하였다. 1. 1日中 光合成能은 氣孔傳導率의 增加에 따라서 直線的으로 增加하였고, 光合成의 變異의 75%을 차지하였다. 2. 次葉身의 光合成能은 止葉보다 7%, 제3葉身은 37∼45%程度 各各 낮았다. 無芒種의 葉位別 葉身의 平均 光合成能은 6.1∼9.7 CO_2 umole m^-1s^-1로 長芒種보다 매우 높았다. 3. 出穗期 또는 出穗 7∼10일후 旱魃條件에서 光量, 葉綠素含量, 葉溫은 對照區보다 平均 2∼5% 낮았으며, 氣孔傳導率은 28∼49%, 蒸散量은 15∼31%, RuDPCase活性은 8%, 光合成能은 25∼28%가 各各 減少되었다. 4. 實驗年度 및 旱魃處理時期에 따라 다소 차이가 있지만 光合成能은 光量·蒸散量, 氣孔傳導率 및 葉綠素含量과 正 相關 關係가 있었다. 5. 旱魃處理에 의해 穀粒重이 5∼9% 減少되었지만, 長芒種에 비해서 無芒種의 結實穀粒數와 穀粒重의 減少率이 더 컸다. 6. 本 實驗에서 供試된 無芒種은 長芒種에 비하여 葉身의 光合成能이 크고, 總生體重이 커서 總體型 飼料의 草型으로 적당한 系統이라고 생각된다.

도라지(Platycodon grandiflorum DC.)의 成分分析에 關한 硏究

金鶴鎭,申東永,趙聖均 順天大學校 農業科學硏究所 1991 農業科學硏究 Vol.5 No.-

Bell flower root(Platycodon grandiflorum DC) collected from 8 different areas of Korea were analyzed for inorganic and proximate compositions including saponin content in the root. The results are summarized as follows. Analysis on the inorganic compositions of root showed the highest amout P and Ca, the lowest Mg and Fe with the exception K. There were wide variations in the inorganic compositions of root collected from different sites. The amount of proximate compositions were in the order of soluble nitrogen, starch, crude ash. Saponin content in the root was different due to the collected areas and the highest amount was showed in the ones collected from Daejun, Gurae and Sunchon. The most prevalent ginsenoside fraction was Rb_2 followed by Rg_1 and Rc.

低溫, 日長 및 Gibberellin處理가 튜립 (Tulipa gesneriana L.)의 生長과 開花에 미치는 影響

徐正根,金賢子 順天大學校 農業科學硏究所 1990 農業科學硏究 Vol.4 No.-

This study was carried out to investigate the growth and flowering response of Tulipa gesneriana L. according to the low temperature treatment of bulbs(special precooling), photoperiod and method of gibberellin(GA_3) application in forcing. Regardless of low temperature and GA_3 treatment, the flowering percentage of cvs. Apeldoorn and Golden Apeldoorn was more than 90%, but it was low in cv. Red Matador. The flowering percentage of cv. Red Matador was markedly increased by 0.5㎎ GA_3 injected into the flower-bud. Any effect of photoperiod on the flowering response of cv. Apeldoorn was not observed. Flowering date in all cultivars was advanced by gibberellin injected into bulb scale tissue and the flower bud when bulbs had been stored at 5℃ for 6 week, although there were difference between cultivars. There were no effects due to photoperiod. Total stem length was somewhat shorter after injection of GA_3 into bulb tissue and the flower bud compared with untreated plants. For cv. Apeldoorn, total flower stem was slightly reduced by GA_3 injected into bulb scale tissue and long day treatment when bulb had been stored at 5℃ for 9 week. The growth of the neck in cv. Apeldoorn was slightly reduced by gibberellin injected into bulb when bulb stored at 5℃ for 6 or 9 week. It is, therefore, suggested that GA_3 injected into bulb scale tissue and the flower-bud can be used for control of the flowering date and to prevent bud blasting.

米飯의 香氣成分에 대한 연구 : Ⅰ. 一般米飯과 香米飯

鄭賢淑 順天大學校 農業科學硏究所 1990 農業科學硏究 Vol.4 No.-

By trying to separate and identify Head Space volatile flavor components and total volatile components extracted from the cooked rices of Ordinary Rice(Koshihikari)and Flavor Rice(Kaorimai) each kept unfilled at a low temperature and polished at the laboratory, the writer got the following results with the help of GC and GC/MS. Flavor Rice is richer than Ordinary Rice in Head Space volatile flavor components. About 25kinds of Head Space volatile flavor components are separated, and the number of the kinds does not change according to the thermal storage time of 1 and 6 hours. Of Head Space volatile components in the cooked rices, Hydrocarbons, that is tetracycline, 2-methyl pentadecane and 2-methyl-2-nonene are presumed to be the main components. Of total volatile components, about 10 components are generally separated, as though Flavor Rice has a little more than Ordinary. The longer the thermal storage time extends up to 24hours, Head Space volatile flavor components as well as total volatile components volatilize and are lost as time goes on.

Epidemiological Characteristics of Slow-leaf-blasting Resistance of Rice

Koh,Young Jin,Chung, Hoo Sup 順天大學校 農業科學硏究所 1989 農業科學硏究 Vol.3 No.-

벼 品種의 slow-leaf-blasting形 低抗性의 特徵을 여러 가지 疫學地標를 使用하여 調査하였다. 供識品種 모두 밭못자리에서 幼苗滔熱炳에 대해 感受性이었지만, 農白과 銀河는 本畓에서 感受性品種 洛東, 農林6號 및 振興보다 잎滔熱炳의 發生이 늦고 進展이 느리며 發病量도 적었다. 供試한 疫學地標 중에서 病進展曲線面積은 Vanderplank의 傳染速度보다 벼 品種의 滔熱炳 抵抗性 平價에 더 有用하였으며, Gompertz모델이 logistic모델보다 잎滔熱炳 進展狀況을 자세히 記述하였다. 작은 炳進展曲線面積과 낮은 傳染速度 및 切片으로 特徵지워지는 벼 品種의 slow-leaf-blasting形 低抗性은 圃場에서 늦은 發病과 느린 病進展으로 顯著하게 적은 發病量만을 許容하는 벼 品種의 相對的인 能力으로 定義할 수 있다. Characteristics of slow-leaf-blasting resistance of rice cultivars were assessed using several epidemic parameters. All the cultivars tested were susceptible to seedling blast in upland nurseries, but Nongbaek and Ginga had less amount of leaf blast severity with later disease onset and slower disease development than did susceptible cultivars Nakdong, Norin 6 and Jinheung in flooded fields. Among the epidemic parameters tested, areas under disease progress curves were more useful than Vanderplank's apparent infection rates for the evaluation of leaf blast resistance of rice cultivars, and Gompertz model described the more precise states of leaf blast progress than logistic model. Slow-leaf-blasting resistance of rice cultivars characterized by small areas under disease progress curves and low infection rates and intercepts can be defined as the relative ability of rice cultivars to permit only a distinctly little amount of leaf blast severity with late disease onset and slow disease development in fields.
