        韓相政 대구효성가톨릭대학교 1981 연구논문집 Vol.23 No.3

        Many different kinds of vegetables under various cultural types, in general, are grown in the suburbs of cities and the fresh vegetables produced are supplied to townpeople throughout the year. This report was made to obtain the informations for the lan of supply and production of vegetables and the improvements of cultural techniques by investigating of cultural status of vegetables in the suburbs of Daegu. In the suburbs of Daegu, the kinds of vegetables and types of culture were very simple. The supply duration was limited the cultural technique was poor, especially in house-culture and the production was unstable. The ways of improvement for these were discussed and suggested.

      • 韓國産 野生달래의 農耕形質에 關한 硏究

        韓相政 대구효성 가톨릭 대학교 1990 연구논문집 Vol.40 No.1

        This study was conducted to obtain information on selection of superior local variety and cultural practice development in Allium grayi. Four local varieties were cultivated under keeping warm and investigated some useful characters, planting date and soil adaptation. 1. Leaf length of Jeju, Milyang and Daegu local varieties were about the same, but that of Ulleung local variety was longer than those of the others. The number of leaves of Ulleung, Jeju and Daegu local varieties were not different from one another, but that of Milyang local variety was significantly more than those of the others. The leaf weight of Ulleung and Milyang varieties were about the same. 2. Not only mother bulb weight of Ulleung and Milyang local varieties but also those of Jeju and Daegu local varieties were not different from each other. The former, however, was significantly heavier than the latter. The bulblet weight and number of bulblet of Milyang local variety were significantly higher than those of the others. 3. When planting date were on August 10. 30 and September 19, leaf emergence date of Daegu and Ulleung local varieties were early in October. When planting dates were on October 9 and 29, as planting date was later, leaf emergence date became also later. But, all the time, leaf emergence date of Ulleung local variety was faster than that of Daegu local variety. 4. When planting dates were on August 10, 30 and September 19, yields of Daegu and Ulleung local varieties were not different from each other according to planting date. On and after September 19, as planting date was later, yield became less decreased. 5. As Daegu local variety was cultivated in loamy sand, loam and clay loam, the yield of that was the most in loamy sand but the least in clay loam.

      • 韓國在來種부추의 核型分析,生長解析과 日長이 生育 및 花芽分化에 미치는 影響

        韓相政 대구효성가톨릭대학교 1985 연구논문집 Vol.31 No.1

        In order to obtain the information for the breeding and improvement of cultural method in Korean native Chinese chives, karyotype analysis, quantitative growth analysis, elements and response to day length were investigated. 1) The somatic chromosome number was 32 and the karyotype formular was K(2n)=28V+2J+2J?. The karyotype was characterized by twenty eight metacentric or submetacentric, two subterocentric and two subterocentric chromosomes with satellite on their short arms. Total length of somatic chromosomes were from 18.3 to 11.3?, those of long arms from 9.7 to 6.8? and those of short arms from 9.0 to 2.6?. Total lengths of 28 V-shaped chromosomes were from 18.3 to 11.7?. 2) Until 28 days after sowing (Sep.24), a growth curve in dry matter of whole plant was a gentle slope, but from after that time to 112 days after sowing (Dec.17), it was a steep slope to upwards. Generally, it was similar to the that of rrot after 56days from sowing. Growth icrement of leaf increased slow from 56 to 112 days after sowing (Dec.17) and decreased rapidly after that time. But that of bulb increased contimuously. From 14 to 28 dats after sowing (Sep.10-24), specific growth rate was maximun and after that time it had a tendency to decrease gradually. 3) At spring sowing culture in greenhouse, long day length (17 hrs.) treatment advanced tillering stage, and increased tillering number, leaf number, plant height and fresh weight in comparion with short day length(10 hrs.) treatment. While natural day length was long, difference of growth increment between long day length treatment and natural condition was a little, as natural day length, however, approaches short, growth in natural condition was delayed remarkablly. At non-heated culture in greenhouse in short day season, the yield increase effect of long day length was recognized. 4) At spring (Apr.27)and autumn (Aug. 27)sowing culture of Chinese chives in greenhouse, which had been differentiated flower bud weren't observed in long day length treatment, short day length treatment and natural day length, until Dec. 21. 5) The contents of moisture, ash,reduced sugar and crude protein in leaf were higher than in bulb but in bulb, dry matter and starch were mch. vitamine C content in leaf was 0.33g/100g dry mateer.

        韓相政 대구효성가톨릭대학교 1974 연구논문집 Vol.14 No.1

        本實驗은 무우, 배추의 初期生育에 미치는 Gibberellin의 處理效果를 檢討하고저 實施한 것으로서 얻어진 結果를 要約하면 다음과 같다. 1) 무우의 晉州大坪品種과 蔚山在來品種은 50PPM處理區에서 效果가 認定되지 않았으나 100PPM 및 200PPM 處理區에서는 調査形質의 大部分이 多少 增加하여 生育이 促進되었다. 2) 이들 2個品種 무우의 各處理區間에 形質의 差異는 認定되지 않았으나 無處理區에 比하여 가장 生育이 促進된것은 晉州大坪品種의 100PPM處理區로서 葉重, 葉長 및 根長이 有意하게 增加되었다. 3) 그러나 蔚山在來品種에서는 오직 200PPM 處理區의 葉長만 有意하게 增加되어 Gibbererellin反應의 品種間 差異가 認定되었다. 4) 배추는 靑邦苦根品種과 京都3號品種의 各處理區가 無處理區에 比하여 共通的으로 T/R率을 除外한 其他形質들이 增加하여 生育이 促進되었으나 뿌리에 비하여 잎의 生育은 보다 促進되었다. 5) 이들 2個品種 배추의 各處理區間에 形質의 差異는 認定되지 않았으나 共通的으로 100PPM處理區에서 生育이 最高에 達했고 無處理區에 대해서 葉重, 根重 및 葉長이 有意하게 增加되었다. 6) 무우에서는 生育初期收量을 높이기 爲한 Gibberellin의 實用化가 期待되지 않으나 배추에서는 實用化가 期待되고 그의 適定濃度는 100PPM라고 믿어졌다. This studies were made to observe the effects of gibberellin on early growth of radish and Chinese cabbage. The results obtained were summarized as follows; 1) No effects of 50 PPM treatment plot were observed in both varieties of Jinjoo-daepyung and Woolsan-jele of radish and the most of characters investigated increased comparatively in 100PPM and 200PPM treatment plots. 2) There were no differences between treatment plots in these two varieties. However, leaf weight, leaf length and root length in 100PPM treatment plot of Jinjoo-daepyung variety increased significantly, compared with check plot. 3) In Woolsan-jele variety, leaf length of 200PPM treatment plot increased significantly, and the difference of gibberellin effects of observed between aboved two varieties. 4) The most of characters excepting T/R ratio in gibberellin treatment plots increased in both varieties of Chungbang-bobeun and Kyto No.3 of Chinese cabbage and growth of leaf was more promoted than that of the roots. 5) There were no differences of characters between treatment plots in these two varieties. However, the growth was vigorous in 100PPM treatment plot and leaf weight, leaf length and root weight increased significantly as compared with check. 6) According to the results, practical utilization of gibberellin to promote the early growth of radish could not be expected. However, in Chinese cabbage the practical use of gibberellin would be expected and it was believed the optimum concentration would be 100PPM.

        한상정 대구효성가톨릭대학교 1997 연구논문집 Vol.55 No.2

        풋마늘의 동계시설재배에 필요한 자료를 얻고자 3품종의 난지형 마늘종구를 저온처리하여 자연일장과 광중단으로 온실에서 실험하였다. 1) 20일, 40일 및 60일간 저온처리한 종구와 무처리종구를 자연일장으로 재배한 실험에서는 어느 경우에 있어서도 녹엽면적은 심양품종이 가장 넓고 그 다음이 상해품종이였으며, 구종은 상해품종이 가장 무겁고 그 다음이 심양품종이였다. 그리고 제주품종의 녹엽면적과 구중은 위의 2품종에 미치지 못하였다. 2) 심양품종의 녹엽면적은 무처리구와 각저온처리구가에 비슷하였으나 상해와 제주품종의 녹엽면적은 각각 20일과 40일간 처리구에서 가장 넓었다. 그리고 무처리구와 각저온처리구의 녹엽면적과 구중은 증가를 계속하여 파종후 112일에 최대치를 나타내었다. 3) 20일, 40일 및 60일간 저온처리한 종구와 무처리종구를 광중단으로 재배한 실험에서도 품종간 녹엽면적의 차이는 자연일장으로 재배한 것과 같은 양상을 나타내였다. 그러나 처리구간 녹엽면적은 20일간 처리의 광중단구에서 3품종 모두 파종후 98일, 40일과 60일간 처리의 광중단구에서는 심양품종이 파종후 98일 그리고 상해와 제주품종이 파종후 85일에 최대치를 나타낸 다음 감소하였다. 그리고 각처리구의 녹엽면적이 최대치를 나타낸 다음 감소하였음에도 불구하고 구중은 증가를 계속하여 파종후 112일에 최대치를 나타내었는데 특히 60일 저온처리의 광중단구에서 가장 현저하였다. 4) 저온처리한 종구를 광중단으로 재배한 것은 자연일장으로 재배한 것보다 녹엽면적을 크게 감소시키지 않으면서 녹엽면적의 최대기가 빨라지고 또한 구중이 증가되었다. This study was carried out to obtain basic data for protected winter culture with three southern ecotype cultivars of garlic when bulb was treated with low temperature as conditions of natural day length and night interruption in the greenhouse. The results obtained in this study were as follows: 1) When seed bulb cultured as conditions both of low temperature for 20, 40, and 60 days and non-treatment under natural day length, green leaf area was wide remarkably in cultival of 'Shenyang' and next was 'Sanghai'. Bulb weight of 'Sanghai' was shown the highest weight and followed a cultival of 'Shenyang'. Green leaf area and bulb weight of 'Jeju' was shown in remarkably a low level as compared with that of two cultivars of 'Sanghai' and 'Shenyang'. 2) Green leaf area of 'Sanghai' and 'Jeju' reached to a maximum level at 20 and 40 days as treated by low temperature, respectively, but that of 'Shenyang' was not changed under non-treatment and each treatment of low temperature. Moreover, green leaf area and bulb weight of three cultivars showed a maximum level at 112 day after planting. 3) When seed bulb was cultured with low temperature treatment for 20, 40, and 60 days and non-treatment under night interruption, a variation of green leaf area among three cultivars showed to a same level as compared with culturing under natural day length. Green leaf area of three cultivars treated for 20 days of low temperature treatment under night interruption reached to a maximum level at 98 day after planting then decreased. In case of low temperature treatment for 40 and 60 days under night interruption, green leaf area of 'Henyang' reached in a maximum level at 98 day after planting then decreased, and that of 'Shanghai' and 'Jeju' revealed a high level at 84 days after planting then decreased. But hulb weight of each treatment was increased gradually after leaf area was decreased, reached in a maximum level at 112 day after planting. Especially, bulb weight showed a maximum level at 60 day of low temperature treatment, under night interruption. 4) When seed bulb treated by low temperature cultured under night interruption, green leaf area was not decreased remarkably as compared with that of culturing under natural day length, and a maximum level of green leaf area was shown to a fast, bulb weight was also weighted.

      • Phosfon-D 및 CCC의 處理가 夏播양배추 育苗時의苗徒長抑制效果 및 收量에 미치는 影響

        李鍾弼,韓相政 대구 효성가톨릭대학교 1968 연구논문집 Vol.1968 No.3

        This experiment was carried out in order to study the effect of Phosfon-D and CCC on suppresive growth young cabbage seedlings sown in summer and on the yield after the transplantation in the field. The summer sown cabbage seedlings often cause unnecessary stem growth and this reduces the yield and produces an unsatisfactory marketable quality. Therefore, the availability of these chemicals in summer cultivated cabbages were investigated.

      • 배추의 Virus 病 抵抗性系統 育成에 關한 試驗

        韓相政 대구 효성가톨릭대학교 1969 연구논문집 Vol.5 No.1

        This studies were carried out in order to use as materials for breeding of the improved varities with resistance to virus diseases and also as cultural varieties through the selection of lines with resistance to virus diseases. 40 lines segregated from leading 4 varieties including Chung-Bang which are growing in Korea. For the test of virus resistance, the seedlings which were growing in net house without aphides, were injected artificially with three purified straines of virus and Radish mosaic virus complex. And they were observed comparatively with case plants in the field which were grown without artificial injection.

      • 당근 採種栽培時 整枝方法의 差異가 種子品質 및 普通栽培時의 收量에 미치는 影響

        韓相政 대구효성가톨릭대학교 1970 연구논문집 Vol.6 No.1

        本實驗은 國內에서 栽培되고 있는 主要6品種의 당근을 材料로하여 採種栽培를 實施하되 整技方法을 다르게 하였을 境遇 이들로부터 採種된 種子의 品質 및 採種量을 調査하는 한편 普通栽培時의 收量에 미치는 影響을 檢討하므로써 種子의 品質 및 收量을 同時에 向上시킬 수 있는 效果的인 整技方法을 探素코저 實施한 것으로써 얻어진 結果를 要約하면 다음과 같다. 1) 品種間差異는 認定되나 主輪一輪區로부터 主側三輪區, 主側五輪區 및 主側輪區間에는 僅少한 차이를 보였다. 2) 各種技區別 主輪의 크기는 主輪一輪區로부터 無整技區로 發行됨에 따라 漸次減少되었으며 또한 化輪의 크기에 있어서도 主輪이 가장크며 1次側輪 및 2次側輪 으로 發行됨에 따라 漸次減少되었는데 이와같은 현상은 化輪內의 小率數 및 花數에서도 同一하게 認定되었다. 3) 品種別 各整技區로부터 採種된 種子의 發牙率은 無整技區에 比하여 主輪一輪區가 顯著히 높으나 主輪一輪區, 主側三輪區, 主側五輪區 및 主側輪區間에는 僅少한 차이를 보였다. 그러나 主倫一輪區로부터 無整技區로 移行됨에 따라 漸次 種子의 重量이 減少되었는데 反해서 採種量은 增加되었다. 4) 이들 各整技區로부터 採種된 種子의 數量能力을 檢定하기 爲한 普通栽培에서 나타난 種根의 變化는 品種內 各整技區間에 一律的인 傾向을 認定할 수는 없었다. 그러나 ⓑ紅芯五寸品種이 主側輪區에서 減收되었고 또한 Chantenay 品種이 主側三輪區에서 增收된것을 除外하고는 各品種의 主側輪區間收量이 가장 增收되었거나 또는 가장 增收되었던 다른 整技區에 對해서 差異가 없었다. 5) 이와같이 主輪一輪區는 種子의 品質은 優秀하나 採種量이 적으며 또한 無整技區는 種子의 品質은 不量하나 採種量이 많다고 하는 長短점이 있다. 그러나 主側輪區는 다른 整技區에 比하여 採種量이 많을 뿐 아니라 種子의 品質이 主倫一輪區와 類似하다는 點으로 미루어보아 種子의 品質 및 收量을 同時에 向上시키고저하는 實用的인 採種栽培를 爲해서는 主輪과 1차側輪을 남겨두고 다른 側枝는 摘除하는 것이 좋을 것 같다. This studies were made with six commercial varieties of carrot which are grown in Korea, in order to determine the useful training methods at the culture for seed production which will improve both quality of seeds and the productivity of carrots. The results obtained are summarized as follows; 1) With going from the one main umbel to one main umbel and first lateral umbels, one main umber and four lateral umbels, one main umbel and all first lateral umbels, and control which is untrained plot the date to flowering was gradually delated and flowering period was longer. There were however, the marked differences between one main umbel and control plots in both the date to flowering and the flowering period but between other plots those differences were slight. 2)The plots with the largest size of main umbel was the one main umbel and the next was one main umbel and two first lateral umbels, one main umbel and four first lateral umbels, one main umbel and all first lateral umbels and control plots in the order. Umbel of main stem was the largest and with going from the first lateral to the second and the thirds, it's size was the smaller. There were also shown the same tendency in number of flowers and small umbel in the umbel. 3) Germination percentage of seeds obtained from one main umbel plots was markedly higher than that of control which is untraind plot, there were, however, the slight differences between one main umbel, one main umbel and all first lateral plot. Seed weight was gradually decreased from the one main umbel to one main umbel and two first lateral umbels, one main umbel and four first lateral umbels. one main umbel and all first lateral umbels and control plot, but produced quality of seed was increased in the above order. 4) As results of yield trials with each seed obtained from different traing plots, there were not shown the regular tendercies in the changes of root weight by training methods. But root weight in one main plot umbel and all first lateral umbels plot was generally similar to other plots which were the most prolific excepting ⓑkoushin-gosun and chantenay varieties. 5)As above results it was postulated that one main umbel plot had good quality and less produtcion of seeds and control which is untrained plot had bad quality and higher production and it was belived that for practical seed production to improve the quality and production of seeds the recommendable plot might be main umbel and all first leteral umbels plot which had relatively higher production than in one main umbel plot but in seed quality, was comparable to that.
