박용봉(Yong Bong Park),문창준(Chang Jun Moon),김용덕(Yong Duk Kim) (사)한국생물환경조절학회 2004 생물환경조절학회지 Vol.13 No.2

본 연구는 망실 하우스내에서 봄감자 재배시, brushing 처리가 감자의 도장 방지와 생육과 수량 및 체내 전분함량에 미치는 효과를 구명하기 위하여 수행하였다. 지상부의 생육은 생육 후반기로 갈수록, brushing 처리시간이 길수록 감소하였다. 측지 수도 처리시간이 길수록 감소하는 경향이었다. 경장과 경경은 5월 6일에는 처리간에 비슷하였으나 생육 후반기로 갈수록 모든 처리에서 증가하였는데 평균적으로 30~36 ㎎/100㎠였다. 지상부ㆍ지하부의 생체중과 건물중은 처리시간이 긴 것이 무거웠고, 전분 함량은 무처리에 비해 brushing 처리한 것이, 그리고 처리시간이 긴 것이 높았다. This study was conducted to investigate the effect of brushing on overgrowth inhibition. growth, yield and starch content in spring-grown potato in the netted house. The plant growth of aerial parts was inhibited with growth stage and brushing duration. Especially, The number of lateral branches decreased greatly with brushing duration. The stem length and stem diameter were not different significantly between brushing and non-brushing on May 6. But the stem length was long in later growth stage but short in longer brushing duration. Chlorophyll content by SPAD increased with growth stage regardless of non-brushing duration and ranged from 30 to 36 ㎎/㎠. The fresh and dry weight of aerial part and tuber were heavy in longer brushing duration. Starch content was higher in brushing treatment as compared to non-brushing and increased with brushing duration.

種球의 低溫貯藏 및 生育中의 日長處理가 寒 . 暖地型 마늘의 生育, 鱗莖肥大 및 二次生長에 미치는 影響

朴庸奉 제주대학교 1989 논문집 Vol.28 No.-

種球의 貯藏溫度를 달리하여 採種하고 生育中에 長日處理(16hr)를 實施하여 生育 및 球肥大反應을 調査한 結果 1. 低溫處理(0-15℃, 60日間)한 것은 4-5일, 變溫處理(30-35℃, 30日間, 以後 0-5℃, 30日間)한 것은 2-3日程度 常溫區(20-22℃ 常溫)보다 出現日數가 빨랐다. 2. 草長, 葉長 및 葉草長은 低溫處理區에서 컸고 暖地型은 生育後期인 4월 下旬부터 感少했으나 寒地型은 계속 贈加하였다. 3. 二次生長은 寒地型에서 暖地型보다 많았고 低溫處理區에서 顯著히 增可하였다. 그러나 低溫處理 後 長日處理한 것에서는 10% 以下로 減少 하였다. 4. 鱗片分化는 低溫處理區에서 가장 빨랐으며 暖地型은 1月 21日盾으로 寒地型보다 25日 程度 빨랐다. The effect of seed bulb storage temperatures and long day treatments during the growing season on plant growth, bulbing and secondary growth was investigated for the two ecotypes of garlic. The results are: 1) time required for bulbing was 4 to 5 days shorter at the low temperature (0-5℃ for 60 days ) and 2 to 3 days shorter at the alternate temperature treatment (30-35℃ for 30 days followed by 0-5℃ for 30 days) than the control (20-22℃ constant); 20 plant height, leaf and leaf sheath length were greater at the low temperature. These parameters decrease in the northern type: 3) the secondary growth was severer in the northern type than in the southern type, and severer when the bulbs were stored at low temperature than the low temperature storage alone, in the bulbs when the 60-day low temperature storage was followed by long day (16hrs) growth tratment : 4) clove differentiation in the southern type was 25 days earlier than in the northern type.

박용봉,박문조,한원탁 제주대학교 1986 논문집 Vol.23 No.-

This study was performed to investigate: The ecological difference of two ecotypes "Seushan (northern) and "Cheju(southern)" The effect of temperature (low. high. alternative) and long day treatments on the growth and bulb formation in two ecotypes Translocation of growth regulators and contents of total sugars in garlic plants Identification of isozyme existing in garlic plants by the electrophoretic method. The results are summarized as follows: 1. The experiment of temperature and long day treatments. Sprouting and early growth of the southern type were accelerated by low iemperature treatment but those of long day treatment were not affected. In plant height and leaf sheath length. the southern type was increased more than the northern type until March 20 and the plants that were treated with low temperature were increased considerably as compared with the control There was no difference in the total leaf numbers between two ecotypes but low temperature treatment romoted those as compared to the control. 2. Ecological experiment of two regions The plant height of the southern type was accelerated until March 25 i n Cheju and March 10 in Suweon. but the plant height of the northern type was promoted after April 20. The growth of leaf length and leaf sheath lentth showed no dlfference durting winter. but after March 10 the southern type was increased in Suweon and Cheju. there was no difference in clove number and bulb weight within the regions and seeding time. but those of the southern type were increased as compared with the northern type 3 Analysis of sugar Low temperature treatment tended to increase concetrations of sugar as compard with control and the difference between cultivats was clear Friictosan was increased as the plants grew. especially at the later period of the whole growth with ever): treatment 4 Bioassay at growth regulators Af Rf 0.5-0.6 and Rf 0.4-0.5 Glbgberellin-like substances were detected from the leaf and leaf sheath of northern type and inhibitors were detected at Rf 0.7-0.9 While 5. The change of Isozyme patterns It was noted that the isozyme patterns were similar between two ecotypes in peroxidase. There was no difference at the bands which means acid phosphatase in two types. There were three or four bands which showed Malate dehydrogenase. but also showed the similar tendency according to the cultivars and every parts.

菜蔬類 種子發芽에 關한 硏究 : 1. Effect of N??-benzyladenine on germination of celery seeds in light and dark condition 第1報 光, 暗黑상태에서 Celery(Apium graveolens L.) 種子의 發芽에 미치는 N??-benzyladenine의 影響

朴庸奉 제주대학교 1983 논문집 Vol.16 No.-

Celery種子는 發芽期間이 길고 高溫期에는 發芽가 不良하고 特히 暗黑상태에서는 發芽率이 극히 떨어지는 菜蔬인데 BA를 處理 함으로써 發芽促進의 效果와 實用化를 究明코저 BA를 濃度別로, Celery 品種 Cornel 619號에 處理하여 試驗한 結果는 다음과 같다. 1) 發芽床處理에서는 5ppm까지는 對照區 보다 發芽率, 發芽勢가 增加되었고 平均發芽期間도 短縮되었다. 2) 2時間 浸淸處理 試驗에서는 光條件 暗黑상태 모두 낮은 濃度에서 發芽率, 發芽勢가 增加 하였으나 平均發芽期間은 오히려 濃度가 높을수록 增加하는 傾向을 보였다. 3) 1時間浸淸處理와 30分處理 試驗에서 光條件下에서는 濃度가 높을수록 發芽率, 發芽勢가 떨어졌으며 平均發芽期間은 濃度間에 差異가 없었으나 對照區보다 促進되었다. 暗黑상태에서는 濃度間에 差異가 없었다. 4) 以上의 結果로서 BA發芽床處理나 1時間, 30分浸淸處理로서 高溫期와 暗黑상태에서 發芽를 促進시킬 수 있으리라 생각되었다. In the view of difficulty in seed germination of Celery during the high temperature season and in the dark condition, a study was conducted with N6-benzladenine(BA) to investigate any promote influence of the germination of celery var. Cornel #619 seeds and its practical value when applied at various concentration. 1. The seed-bed treatment of the 5 ppm or its low levels of BA showed promoted germination of seeds and shortened mean number of days necessary for germination. 2. When the Celery seed was dipped in BA at the lower and higher Concentration, it was found that BA increased both germinating percentage and also advanced germinating speed. 3. When seed was dipped for 1 hour and 30 minute in the higher concentration of BA both germinating percentage and speed of germination decreased. There was no relationship between BA concentration and germination time, However germination was more advanced than in the control. 4. The result show that dipping speed for 30 minute and 1 hour not only restores slow germination in this country but also has possible practical uses in promoting germination of Celery seed in dark conditions.

朴庸奉,李相淳 濟州大學校 亞熱帶農業硏究所 1990 亞熱帶農業硏究 Vol.7 No.-

日長處理에 따른 시금치의 生育反應과 體內成分含量관계를 규명코져 수행했던 結果를 보고코져 한다. 1) 시금치의 生育상태는 韓國種이 日本種보다 良好하였고, 日長이 길수록 生育이 促進된다는 傾向을 보였다. 2) 抽苔率은 日長이 길수록 높았는데 16時間 處理한 것에서 현저히 높았다. 3) 糖含量은 두 品種間에는 差異가 없었으나 日長이 길수록 自然日長보다 減少하였다. 4) 비타민 C의 含量은 韓國種이 日本種보다 增加하였고 16時間 長日處理한 것에서 현저히 많았다. 5) 品種間에는 韓國種이 미량원소가 많았고 日長處理別로는 N는 短日상태에서, K는 自然日長에서, Ca, Mg 및 Fe는 長日狀態에서 各各 많아지는 傾向을 보였다. This study was carried out to examine the growth responsibility and inorganic compound contents of autum spinach, according to length of treatment. The results are summarised as follows : 1) Spinach growth was increased in the Korean variety, more than in the Japanese variety, but as the length of treatment was longer, the condition of plant growth is superior to that of any other plot. 2) Also, the longer the treatment period, the bolting ratio became higher, and in the 16 hours treatment plot, it appeared higher than any other plot. 3) There was no difference in sugar contents within each variety. However, the longer the treatment period, the less sugar contents. 4) Regarding vitamin c contents, as related to a 16 hour treatment period, it increased more than any other plot. 5) Regarding inorganic compound contents, microelements increased more in the Korean variety than in the Japanese variety, according to length of treatment. Nitrogen increased with the short day treatment, potassium increased in a natural day length, Calcium, Magnesium and Iron increased in the long day treatment.
