金度勳,정규관 東亞大學校生命資源科學大學附設 農業資源硏究所 1993 農業生命資援硏究 Vol.2 No.1

水稻의 栽培에서 窒素施用量을 10a當 15, 20 및 25㎏의 3水準과 3種의 生長調整劑를 出穗前 35日에 Ethrel 500, 750 및 1000ppm, 2,4-D 3000, 4000 및 5000ppm, CC 2000, 3000 및 4000ppm과 無撤布 對照區의 10個의 處理를 한 試驗⑴, 그리고 出穗前 35日에 2,4-d 2500, 3000 및 3500ppm과 無撤布 對照區의 4個의 處理를 한 試驗⑵의 結果를 要約하면 다음과 같다. 1.稻體內의 ADF 및 cellulose含量은 窒素施用量과 生長調整劑의 處理에 의한 差異는 없었으며, lignin含量은 2,4-Ddml의 處理에 의하여 增加하였으며 그 濃度가 높을수록 增加程度가 컸다. 2.稈基部의 炭水化物含量은 2,4-D處理로 높아졌고, 그 濃度가 높아짐에 따라 增加度가 컸으며, 蛋白質含量은 反對로 減少하였다. 3.Phenylalanine ammonia lyase 및 peroxidase의 活性은 2,4-D의 處理로 增加했고 濃度가 높을수록 增加度가 컸으며, 3000 및 3500ppm 撤布區는 對照區에 비해 有意的인 差異를 나타냈다. TThe experiments were treated with 15, 20 and 25㎏/10a nitrogen application of 3 levels and 3 kinds of growth retarants: Exp. 1 was treated that Ethrel 500, 750nd 1000ppm, 2,4-D 3000, 4000 and 5000ppm, CC 2000, 30000 and 4000ppm and control of 10 levels were sprayed at 35 days before heading. Exp. 2 was treated with 2,4-D 2500, 3000 and 3500ppm and control of 4 levels at 35 days before heading, and the results obtained were as follows: 1. ADF and cellulose contents were not revealed significant difference in nitrogen application and growth retardant treatments, and lignin content was increased according to the increase of 2,4-D concentration. 2. In culm base, carbohydrate content was increased by 2,4-D treatment and was increased according to the increase of 2,4-d concentration, but protein content was decreased. 3.Phenylalanine ammonia lyase and peroxidase activity became higher lead to the increase of 2,4-D concentration, and the significant differences was convinced by comparing with control in the 2,4-D 3000 and 3500ppm.

曺永守,정규관 東亞大學校生命資源科學大學附設 農業資源硏究所 1993 農業生命資援硏究 Vol.2 No.2

콩과 식물에는 isoflavone의 유도체로서 comestrol, biochanin-A 등이 존재하고, leaf protein 제조때 一部 移行하는 것이 알려져 있기 때문에 isoflavones를 rat에 급여 血淸콜레스테롤 농도에 대하여 영향을 검토하였다. 콜레스테롤 무첨가 식이에 coumestrol 50 ppm, 콜레스테롤 첨가 식이에 coumestrol 50 ppm 및 100 ppm, biochanin-A, 0.075, 0.150%를 혼합하여, 7주령의 Wistar계 수컷 rat에 21일간 급여하여, 혈청지질을 측정하였다. 그 결과, 어느 경우도 isoflavones첨가군 및 대조군 간에는 血淸 총콜레스테롤, HDL-콜레스테롤 LDL- 콜레스테롤, triglyceride는 差가 인정되지 않았다. Isoflavones are widely distributed in legumes. It had been reported that isoflavones exhibited hypocholesterolemic activity in rats. I have undertaken a study of these isoflavones with regard to their effect on the rat. In this study, the effects of coumestrol and biochanin-A on the serum cholesterol level in rats fed with cholesterol free and cholesterol enriched diets were examed. The commercially available isoflavones were purchased in the experiment. Coumestrol were incoporated in the diet at a level of 0.50 ppm without cholesterol free diet and 0, 50, 100 ppm with cholesterol enriched diet. biochanin-A were incoporated 0, 0.075 and 0.150 % with cholesterol enriched diets. These diets were fed for 3 weeks to male wistar strain rats with a body weight of 90∼100g. It was found no significant changes in serum lipids level in the isoflavone fed rats in both cholesterol free and cholesterol-enriched diet.

The air pollution of NO, of the central part of a Pusan is more intensive that of the outskirts of Pusan city.

耐蟲性 水稻品種에서 屢代飼育된 벼멸구의 生態型 發達에 관한 硏究

安始榮,정규관,金種喆 東亞大學校生命資源科學大學附設 農業資源硏究所 1993 農業生命資援硏究 Vol.2 No.1

耐蟲性 水稻品種을 加害할 수 있는 새로운 벼멸구(Nilaparvata lugens Stal) 生態型의 人爲的 選拔을 위해 選拔世代別 生存率, 羽化率, 發育期間, 成長指數, 成 의 體重, 攝食量 및 被害度를 調査한바 그 結果는 다음과 같다. 1.三綱벼와 密陽 63號는 生存率이 各各 51.8%, 56.8%로 나타나 耐蟲性反應을 보였으나, 秋晴벼는 97.9%로 높게 나타나 感受性反應을 나타내었다. 2.第1世代에서 三綱벼와 密陽 63號는 낮은 生存率을 보였으나 世代가 進行됨에 따라 漸次 높게 나타나 第11世代에서는 各各 91%, 94%로 感受性品種 秋晴벼의 95%와 거의 같은 生存率을 나타내었다. 3.三綱벼系(生態型-2)와 密陽 63號系(生態型-3)는 各各 三綱벼와 密陽 63號에서 秋晴벼와 같이 羽化率, 成長指數 및 成 의 體重이 높게 나타났으며, 또 若 期間도 짧게 나타났다. 4.filter paper 위에 나타난 甘露排泄面積과 排泄된 甘露의 무게와는 서로 相關이 있었다. 즉 三綱벼系는 三綱벼에서, 密陽 63號系는 密陽 63號에서 甘露排泄面積과 무게가 모두 높게 나타났다. 5.三綱벼系와 密陽 63號系는 各各 三綱벼와 密陽 63號에서 接種 30日, 26日 後에 被害度 9.0을 나타내어 感受性反應을 나타내었다. The present study was designed to obtain detailed information on some of the processes involved in the selection of biotypes of brown planthopper(BPH), Nilaparvata lugens Stal, on the rice cultivars with different major genes for resistance. The BPH population selected for the study has been reared on a susceptible cultivar(Chucheongbyeo) for 10years and initially had a low survival on the resistant rice cultivars, Samgangbyeo(Bph-1 gene) and Milyang 63(bph-2 gene) and high survival on the susceptible cultivar, Chucheongbyeo(no gene). Monitoring the survival and length of the developmental period for eleven generations indicated a progressive increase in the survival and shortening of the nymphal period in each heneration on the resistant cultivars until they were similar to Chucheongbyeo. The feeding amount of the BPH biotype-1 reared for eleven generations on Samgangbyeo or Milyang 63 was as high as Chucheongbyeo with no resistant gene, but biotype-1 reared on susceptible rice cultivar was remarkably lower on Samgangbyeo and Milyang 63 than on Chucheonbgyeo. In addition, the BPH populations selected on Samgangbyeo or Milyang 63 were able to kill Samgangbyeo or Milyang 63 in the 11th generation, respectively. But Samgangbyeo biotype was able to kill Milyang 63 and Milyang 63 biotype ot able to kill Samgangbyeo in the 11th generation.

牧草의 混播가 分蘗數 및 葡蔔枝數에 미치는 影響

丁海鎭,정규관,朴永道 東亞大學校生命資源科學大學附設 農業資源硏究所 1994 農業生命資援硏究 Vol.3 No.1

牧草의 混播가 植生變化에 미치는 影響을 究明하고자 禾本科牧草를 5個 草種 6品種과 荳科牧草 2個 草種 4品種을 供試하여 5㎝×5㎝ 栽植거리로서 人爲的으로 混播集團을 形成, 栽培하여 分蘗數 및 葡萄枝數를 調査한 結果 다음과 같다. 1. 各 草種別 分蘗數는 perennial ryegrass(CV. Antrim, Rathlin)가 가장 많았고, hybrid ryegrass(CV. Augusta), meadow fescue(CV. S. 215), tall fescue(CV. Dovey), cocksfoot(CV. Cambria) 順으로 減少되었으며, 荳科牧草는 white clover(CV. S. 184, Donna)가 red clover(CV. Astra, Deben)보다 높게 나타났다. 2. 荳科牧草는 半直立型이며 잎이 좁거나 짧고 分蘗力이 中間程度인 cocksfoot, meadow fescue와 같은 禾本科牧草와의 混播에서 生育과 收量이 良好하였다. 3. 荳科의 越冬率이 높았던 混播組合에서는 葡萄枝數가 增大되고 荳科比率이 높아져서 總收量이 增大되었다. With a purpose to investigate the effects of grass-clover mixtures on herbage yield and sward composition, a set of sward canopy of grass-clover mixtures with d density of 5㎝×5㎝ was established with six cultivars of grasses and two cultivars of legumes. The number of tillers of stolons per plant and sward composition of mixtures was compared with that of single stand. The number of tillers per plant was highest in perennial ryegrass(CV. Antrim, Rathlin), followed by hybrid ryegrass(CV. Augusta), meadow fescue(CV. S. 215), tall fescue(CV. Dovey), and cocksfoot(CV. Cambria). When the legumes were combined with the grasses which have semierect plant type bearing narrow and short leaves with a medium tillering capacity, the dry matter yield of the mixtures increased significantly. Higher wintering rate in grass-clover mixtures resulted in an increase of stolones, higher compositions of legumes in the mixture, and consequently higher herbage yield.
