宋昌吉 濟州大學校 亞熱帶農嶪硏究所 1992 亞熱帶農業硏究 Vol.9 No.-

율무에 대한 生長調節物質의 反應을 追究하고자, 生長調節物質 ABA(0.1, 1 및 100ppm), CC(10, 100 및 1000ppm), Ethrel(500, 1000 및 2000ppm) 및 CC(10, 100 및 1000ppm) 그리고 無處理등 13水準을 處理한 試驗結果를 要約하면 다음과 같다. ABA, CCC, Ethrel 및 CC의 生長調節劑 名 農度液의 撒布의하여 草長 및 最長節性間長을 短縮시켰으며,倒布 輕感되었는데, 특히 Ethrel 1000ppm 및 2000ppm撤布區에서 耐倒伏性이有意하게 높았다. 葉中 葉綠素含量은 ABA, CCC, Ethrel 및 CC의 撒布모두 無處理에 비하여 葉綠素含量이 높았는데, 특히 CC 및 Ethrel의 撒布는 有意하게 높았다. 生長調節物質撒布에 의하여 100粒重, 種實, 1ℓ重, 種實收量은 대체로 增大하는 傾向을 보였는데, 收量이 有意하게 높은 것은 生長調節劑 ABA 10ppm, CCC 1000ppm 및 100ppm, Ethrel 1000ppm 및 500ppm, 그리고 CC 10ppm 撒布區였다. 生長調節濟撒布에 의하여 粗蛋白質, 粗殿粉, 粗脂肪은 大體로 增加하는 傾向을 보였다. The study is on the response of growth regulator having an effect on adlay plant. This experiment was carried out with definite growth regulators, such as ABA (0.1, 1, 10ppm), CCC (10, 100, 1000ppm), Ethrel (500, 1000, 2000ppm), CC (10, 100, 1000ppm) and control plot. The results obtained can be summarized as followers: Dispersing ABA, CCC, Ethrel and CC liquid got its plant height and internode length shortened, what's more, lodging reduced. Especially, on the dispersal plot of Ethrel liquid 1000ppm, 2000ppm, lodging tolerance appeared high significantly. Chlorophyll content of its leaf increased on the dispersal plot of ABA, CCC, Ethrel and CC in comparison with control plot, Especially, dispersing CC and Ethrel had its content increased significantly. In case of using growth regulator, by and large, the weight of 100 grains, 1 liter grain and grain yield were inclined to increase. On the plot dispersed with ABA 10ppm, CCC 1000, 100ppm, Ethrel 1000, 500ppm and CC liquid 10ppm, a good yield was significant. By means of the dispersal of growth regulator, content of crude protein, crude starch and crude fat were inclined to increase.

趙南棋,金翰琳,宋昌吉 제주대학교 1983 논문집 Vol.16 No.-

本 硏究는 濟州道 中山間地帶의 自然草地(Imperata cylindrica/Zoysia japonica type)를 開墾한 後 1 ha當 Dactylis glomerata 17kg, Festuca arundinacea 7kg, Lolium multiflorum 2kg, Trifolium repens 2kg의 導入牧草를 混播(28kg)하여 家畜放牧에 利用되고 있는(1977∼1982年) 改良草地를 對象으로하여, 띠(Imperata cylindrica)植生의 季節的ㆍ年次的變化過程을 調査한 結果를 要約하면 다음과 같다. 1. 每年 季節에 따르는 草長ㆍ收量ㆍ密度ㆍ被度 等 植生의 季節的 變化에 있어서는 秋期에 가장 優勢하였고, 春期에는 低調하게 나타났다. 2. 改良後 年度別 草長의 變化는 1年草地에서 34.26cm이었으나 점차 增加되어 6年草地에서는 49.35cm이었는데, 이 變化狀態의 回歸方程式은 y=-0.13x²+4.41x+28.50이었다. 3. 年數의 經過에 따르는 密度의 變化는 1年草地에서 0.76%였던 것이 年數가 지남에 따라 급격히 增加되어 6年草地에 이르러서는 32.97%로 나타나고 있는데, 이 變化를 y=0.10x²+0.32x-2.30의 回歸方程式으로 表示할 수 있었다. 4. 草地造成 以後 年次別 被度의 變化는 1年草地에서 1.05%, 2年 1.38%, 3年 2.46%, 4年 17.11%, 5年 27.56%, 6年草地에서 36.66%로 每年 增加(y=1.40x²-2.36x+1.39)되었다. 5. 收量의 年次的 變化는 1年草地에서 1.95kg이었으나 年數가 지남에 따라 점차 增加되어 6年草地에서는 1,107.35kg으로 나타났는데, 이 變化狀態를 y=29.11x²+53.52x-154.67로 表示할 수 있었다. This study was conducted to examine the yearly and seasonal changes of Imperata cylindrica on the improved pasture of the mountain districts around Mt. Halla in Cheju Island. For this study, the researcher had investigated for six years from 1977 to 1982 the improved pasture which had been used for grazing from 1977 to 1982. The pasture was reclaimed from native grassland. The mixed seeds of 17kgs' Datylis glomerata, 7kgs' Festuca arundinacea, 2 kgs' Lolium multiflorum and 2kgs' Trifolium repens were sowed per 1 ha. The results of this study are the following : 1. The seasonal changes of Imperata cylindrica : its length, weight, density and coverage are heighest in Autumn, and are lowest in Spring every year. 2. The yearly change in the length of Imperata cylindrica : its length is gradually increased from 34.26 cm in the first year after the reclaimation to 49.35 cm in the 6th year. This change can be represented by the regression equation, Y=-0.13x²+4.41x+28.50. 3. The yearly change in its density : its density is rapidly increased from 0.73% in the first year to 32.97% in the sixth year. The results of this change can be obtained with the regression equation, Y=0.10x²+0.32x-2.30. 4. The yearly change in its coverage : its coverage is increased year by year (1.05% in the 1st year, 1.38% in the 2nd year, 2.46% in the 3rd year, 27.56% in the 5th year, and 36.66% in the 6th year). This change can be calculated with regression equation, Y=1.40x²-2.36x+1.39. 5. The yearly change in its weight : the weight is also increased year after year from 1.95 kg in the first year after reclaimation to 1107.35kg in the sixth year. This change can be calculated with the regression equation of y=29.11x²+53.52x-154.67.

宋昌吉 제주대학교 1990 논문집 Vol.31 No.-

율무의 窒素反應과 生長抑制劑에 대한 反應을 追究하고자, 窒素施用量을 10a當 6,12,18 및 24㎏의 4個水準과 生長抑制劑 ABA(0.1,1.0 및 10ppm) CCC(10,100 및 100ppm), Ethel(500,100 및 200ppm) 및 CC(10,100 및 1000ppm) 그리고 對照區등 13水準을 처리한 試驗結果를 보면 다음과 같다. 窒素施用水準이 높아짐에 따라 草長 및 葉長, 葉幅 그리고 最長節間長은 有意하게 增大하였다. 또한 植物體總乾物重 역시 窒素施用水準이 높아짐에 따라 有意한 增加를 보였으며, 主幹의 乾物重은 窒素 10a當 12㎏ 水準에서 높았고, 이보다 낮거나 높은 水準에서는 減少되었다. 葉中 葉錄素含量은 窒素의 施用水準이 높아짐에 따라 增加하였으며, ABC, CCC, Ethrel 및 CC의 撒布는 모두 對照區에 비하여 葉綠素의 含量이 높았는데, 특히 CC 및 Ethrel의 撒布는 有意하게 높아졌다. The Study is on the response of nitrogen and growth retardant having an effect on adlay plant. This experiment was carried out with maching up 4 levels of amount of manuring nitrogern (6,12,18,2,4㎏/10a) and definite growth retardant, such as ABA(0.1,1.0 10ppm) and control plot. The results obtained can be summarized as follow; In accordance with the rise of the level of nitrogen application., there appeared significant increase in its plant height, leaf length, leaf width, internode length, and weight of dry matter per plant as well. On the plot applicated with nitrogen level(12kg/10a). the dry matter weight of main stem was observed to have increased. On the other hand, it reduced on the application plot with nitrogen level (12kg/10a, or little more). Chlorophyll content of its leaf tended to increase with the rise in the level of nitrogen application. Moreover, the content increased on the dispersal plot of ABA, CCC, Ethrel and CC in comparison with control plot. Especially, dispersing CC and Ethrel had its content increased significantly.

리차드스, 리차드 에이,宋昌吉 濟州大學校亞熱帶農業硏究所 1997 亞熱帶農業硏究 Vol.14 No.-

初期生育이 良好한 小麥品種을 選拔하기 위하여 小麥 9系統을 供試하여 試驗한 結果를 要約하면 다음과 같다. 1) 優秀系統 選拔試驗에 있어서는 장초엽 系統인 경우 Vigour18과 ZL59A가, 단초엽 系統인 경우는 Amery와 Janz가 初期生育이 良好하였다. 2) 生育期 및 窒素水準에 따른 反應에 있어서는 장초엽 系統인 경우 Vigour18이 단초엽 系統인 경우 Janz가 優勢하였다. 3) 播種密度와 窒素水準에 따른 反應에 있어서, 葉面積은 Vigour18, Janz 모두 密植 할수록 작아지고, 普肥區가 少肥區보다 增加하였으며, 葉重, 乾物重, 根重에 있어서도 葉面積과 같은 경향이었다. SLA와 LAR은 密植 할수록 커지고, 少肥區에서 增加 하였는데, Vigour18과 Janz 모두 같은 傾向이었다. 根長은 장초엽 系統인 Vigour18은 3粒播種區에서 最大値를 나타냈으나, 단초엽 系統인 Janz는 2粒播種區에서 最大値를 보였다. This experiment was conducted on the wheat 9 genotypes to choose the wheat which is excellent in the early vigour. The results are as follows. 1. Vigour18 and ZL59A are excellent in the long coleoptile genotype, while Amery and Janz are excellent in the short coleoptile genotype. 2. In responding to the growth stage and nitrogen level, Vigour18 is predominant in the long coleoptile genotype, while Janz in short coleoptile genotype. 3. In the responding to sowing density and nitrogen level, the more the sowing density was, the shorter the leaf area of Vigour18 and Janz tended to grow. Also the leaf area turned out to grow larger in the plot fertilized with high nitrogen than in the plot fertilized with low nitrogen. This is true of leaf weight, dry weight, and root weight. Concerning SLA and LAR, the more the sowing density was, the larger specific leaf area tended to glow, while the specific leaf area grow larger in the plot fertilized with low nitrogen. This is true of both Vigour18 and Janz. The root length of long coleoptile genotype, Vigour18, turned out to grow longest on the plot sown with 3 seeds. While the root of short coleoptile genotype, Janz, grew longest on the plot sown with 2 seeds.
