동할발생조건(胴割發生條件)에 대(對)한 미립(米粒)의 형태(形態)나 성분함량(成分含量)의 영향(影響)을 알고저 비료시용방법(肥料施用方法)을 달리하여 재배(裁培)한 벼의 동할립(桐割粒)과 건전립(健全粒)을 구분(區分)하여 분석(分析)해본 결과(結果) 동할발생(桐割發生)은 삼강(三剛)벼가 락동(洛東)벼보다, 만기수확구(晩期收穫區)가 적기수확구(適期收穫區)보다 많았으며 3요소외(三要素外)에 규산질비료(珪酸質肥料)를 병용함으로서 동할율(桐割率)이 감소(減少)되었다. 동할립(桐割粒)은 건전립(健全粒)에 비(比)하여 천립중(千粒重) 및 미립(米粒)의 체적(體積)(립장(粒長)${\times}$립폭(粒幅)${\times}$립후(粒厚)), 립장(粒長), 립장(粒長)/립폭(粒幅)이 컸으며 품종간(品種間)에는 미립(米粒)의 립장(粒長)/립폭비(粒幅比)가 큰 삼강(三剛)벼가 락동(洛東)벼보다 동할율(胴割率)이 높았다. 동할(胴割)이 비교적(比較的) 잘 되는 삼강(三剛)벼는 미립내(米粒內) 규산함량(珪酸含量)이 낮았고 인산함량(燐酸含量)이 높았으며 동할(胴割)이 잘 안되는 락동(洛東)벼는 그 반대(反對)이었다. 그래서 삼강(三剛)벼는 미립내(米粒內) 규인비(珪燐比)가 낮았고 락동(洛東)벼는 높았으며 비료삼요소(肥料三要素)에 규산(珪酸)을 시용(施用)함으로서 그 함량비(含量比)를 높일수 있었다. To investigate the influences of morphological features and the chemical compound of rice grain on the crack of rice kernels, rice was cultivated under the different method of fertilizer application and was harvested at optimal and late stage to the crack features of kernels of cracked and healthy grains. The results are summarized as follows ; The occurrence of cracked kernel was more severe in "Samgang-byeo" than in "Nagdong-byeo" and the rice harvested at the late stage was more cracked kernel than that of optimal harvest. The application of silicate fertilizer in addition to the N.P.K. fertilizer resulted in the decrease of cracked kernels. The grain weight, the grain volume (length ${\times}$ width ${\times}$ thickness), grain length and grain length/grain width etc. of the cracked kernels were larger than those of the healthy grains. The long "Samgang-byeo", having the long grain Shape, which has larger ratio of grain length/grain width than that of "Nagdong-byeo", shows higher rate of cracked kernels. The grain of "Samgang-byeo" which is easily cracked relatively it contains lower silica and higher phosphorus while "Nagdong-byeo" shows the opposite results. The ratio of silica/phosphorus in the grain was low in "Samgang-byeo" but it was high in "Nagdong-byeo". The ratio of silica/phosphorus in rice grain was increased by the application of silicate fertilizer in addition with N.P.K. fertilizers.

벼箱子育商에서 殺菌劑와 生長調節劑 處理가 苗生育 및 生理障害에 미치는 影響

諸商律,黃正東 慶北大學校出版部 1987 慶北大農學誌 Vol.5 No.-

This study was conducted to evaluate the effeet of several fungicides and growth regulators on rice seedling growth and damping - off in seedling boxes for machine transplanting. Fungicide treated plots were better seedling growth, shoot regrowth, rooting ability, change of moisture content than those of nontreated plot. Metalaxyl application of Samgangbyeo and SF8002 application of Nagdongdyeo apparently increased plant height, length of the third leaf and fourth leaf. And metalaxyl application highly increased dry weight. Fungicide treated plots were highly effective in reducing the incidence of damping - off. Benzyladenine application of Samgangbye and GA_(3) application of Nagdongbyeo apparently increased plant height. But ABA application highly decreased plant height. ABA application and OCE application resulted in highly increased rooting ability. Fungicide and GA_(3) treated plots, Metalaxyl and growth regulator treated plots resulted in highly increased plant height. Isoprothiolane and growth regulator treated plots resulted in decreased plant height. Dachigaren and IAA treated plot apprently increased dry weight and shoot dry weight / plant height. Fungicide and growth regulator treated plots were highly effective in reducing the incidence of damping - off.

除草劑 propanil과 殺蟲劑 Carbofuran의 混用處理가 벼의 生育에 미치는 影響

諸商律,金吉雄,李相哲 慶北大學校 1982 論文集 Vol.33 No.-

This experiment was conducted to know effect of combining treatment of propanil with carbofuran on growth responce of rice. Simultaneous treatment of propanil and carbofuran at the all recommended rate caused slight injury on all rice varieties used, but toxicity markedly increased as the combined rates of both chemicals increased, showing synergistic response. Propanil applied after carbofuran treat resulted in greater toxicity than propanil treatment prior to carbofuran application, but the increased time intervals between application of two chemicals remarkble decreased injury. This would support that propanil is synergistically reacted with carbofuran and more than 10 days-interval should be maintained in order to minimize adversal effect of sequential application of both chemicals.

諸商律,崔章洙 慶北大農學誌編輯委員 1986 慶北大農學誌 Vol.4 No.-

水稻 生有初期에 珪酸을 處理할 때 幼苗의 葉先端으로부터 排出되는 溢液量과 溢液을 通해 어느 程度珪酸이 外部로 排出되며, 溢液中의 珪酸과 葉燒와의 關係를 究明하고저 多收系 品種 삼강벼와 一般系品種 낙동벼를 供試하여, ?度範圍가 29~33℃ 인 室內 自然光下에서 50㎝×150㎝×70㎝인 vinyl 箱子로 密閉하여, 水耕 栽培한 水稻 幼苗에서 採取한 溢液中의 珪酸을 分折 調査하여던 바 結果를 要約하면 다음과 같다. 1. 珪酸 處理 濃度가 200ppm까지 增加할수록 溢液量은 增加하였으며, 珪酸 濃度가 200ppm 일때 溢液量은 낙동벼 4.30㎎/plant, 삼강벼 4.34㎎/plant이었으며, 250ppm以上에서는 溢液量이 減少하였다. 2. 珪酸 處理 濃度가 높을수록 溢液量 含有되어 있는 珪酸의 濃度는 增加하였으며, 溢液中 珪酸의 濃度 對 珪酸 處理 濃度 比는 100ppm 以上에서는 減少하였다. 3. 處理된 珪酸은 短時間에 水稻根으로 吸收되어 溢液을 通해 排出되며 處理 後 12時間에 排出된 溢液에 珪酸의 含量이 가장 많았으며, 珪酸 處理 300ppm에서의 溢液中 珪酸의 濃度는 낙동벼 SiO_(2) 172.6ppm/cc, 삼강벼 SiO_(2) 199.8ppm/cc이었다. 4. 溢液中에 含有되어 있는 珪酸의 濃度와 葉燒의 程度는 正의 相關(낙동벼 r-0.97^(**), 삼강벼r-0.97^(**))이 있었다. This study was conducted to find out the effect of SiO_(2) treatment on the SiO_(2) concentration in guttation liquid, the amount of guttation liquid exudated from the margin of rice leaves, and the relationships between SiO_(2) concentration in guttation liquid and foliar burn during the rice seedling stage, using two rice varieties;Nagdong-byeo (a Japonica) and Samgang-byeo (a - Indica - Japonicahybrid). Seedlings were cultivated in water solution and enveloped in polyvinyl case (50㎝×150㎝×70㎝). SiO_(2) treatment increased the amount of guttation liquid, the amount of guttation liquid (Nagdong-byeo:4.30mg/plant, Samgang-byeo:4.34mg/plant)) treated with 200ppm of SiO_(2) was greater than any other level, decreased over 200ppm of SiO_(2). SiO_(2) concentration in guttation liquid was increased as application rates of SiO_(2) increased, showing the positive correlation, and SiO_(2) in guttation liquid/SiO_(2) in culture ratio decreased over 100ppm of SiO_(2). The highest concenitration of SiO_(2) (Nagdong-byeo:172.6ppm/lcc, Samgang-byeo:199. 8ppm/lcc) in guttation liquid was obtained at 12 hrs after SiO_(2) applied. Foliar burn seemed to be closely related with SiO_(2) concentration in guttation liquid.

不整根移秧이 水稻生育 및 收量에 미치는 影響 硏究

諸商律,李相麗 慶北大學校 1968 論文集 Vol.12 No.-

The authors studied on the effects of unarranged root transplantations rice plant for growth and products at paddy farm of Kyung Pook Univ. in 1967. The results obtained were as follows; 1) Transplanting of unarranged root gives delayed growth at each seeding dates and that about a week was delayed at the latest transplanting block.. Base parts of the unarranged roots were decayd:it was the period to absorb the nutrition at the block of arranged root while growth of unarranged root was delayed because of new root formation at 2nd and 3rd nodes. 2) Earing period was delayed but maturity was hastended at block of unarranged root, These Phenomena was derived from irregular vegetative growth and shortened maturity, the autors believed. 3) Weight of defective grain was high while straw weight was much lowered, So it is the top priority problem to arrange the root when transplanting of rice plant ofr augmentation.

논에 발생하는 주요 다년생잡초 생태에 관한 연구 : 일장처리가 지하경 형성에 미치는 영향과 지하경 절단정도별, 수분조건별, 토심별에 따른 맹아 발생력에 관한 연구

金純哲,諸商律 韓國作物學會 1977 Korean journal of crop science Vol.22 No.1

1. 다년생잡초의 지하경은 단일처리만으로서도 형성되었는데, 단일조건별(시간)로는 11시간까지는 형성량에 큰 차이가 없었다. 2. 다년생잡초 지하경형성을 위한 단일처리의 유도 기간은 잡초종류에따라 차이가 있었는데 벗풀은 2일, 올방개와 너도방동산이는 10일 가래는 30일이었다. 3. 다년생잡초 지하경의 절단정도와 상아발육정도를보면 잡초종류간에 다소 차이가 있었고, 절단방법별로도 차이가 있었다. 그러나 공시잡초 모두 80%절단구에서도 완전히 맹아력을 상실하지는 않았는데 가래는 8%, 올방개는 13%, 벗풀은 100%의 맹아발생율을 보였다. 4. 토양 조건에 따른 발아성을 보면 너도방동산이는 담수상태하에서는 맹아발육이 되지 않았으며, 가래는 너도방동산이와는 반대로 담수상태하에서만 맹아발육되었다. 그러나 올방개, 벗풀은 담수, 포화상태에서 다같이 맹아·발육되었으나 담수상태하에서 더욱 용역하게 맹아 발육되었다. Perennial weeds which were grown in transplanted paddy field formed their tubers under shortday condition. Under short day treatment, the induction periods for tuber formation were different depending upon the weed species. 80% cut tubers of the weeds did not loose their developing ability perfectly. Emergence also affected by soil conditions and depths covered.

이상하,제상률,김길웅 한국연초학회 1982 한국연초학회지 Vol.4 No.2

To investigate the effect of reciprocal grafting between Hyangchio (H) and L. A. Burley 21 (L.A), one a higher producer of nicotine and low yield, the other, a low producer of nicotine and high yield, growth of various parts of each variety and chemical constituents of these parts were evaluated. The results were as follows : The growth of H/H graft was depressed when compared to hyangchio and H/L. A. and L. A. Burley 21 showed most vigorous growth plants having L. A. Burley 21 top. The amount of total alkaloids were low in leaves and stems of plants having L. A. Burley 21 roots (L. A., L. A./L. A., H/L. A.). Plants having Hyangchio roots (H, L. A./H) were high in total alkaloids. The contents of reducing sugar were high in plant having Hyangchio top compared to L. A. Burley 21 tops, but there were not diffences in contents of ether extracts among all treatments.
