제초제 2, 4-D에 대한 고려인삼의 반응 1 : 2, 4-D의 농도가 인삼의 생육 및 근수량이 미치는 영향

曺在星 한국작물학회 1989 Korean journal of crop science Vol.34 No.4

제초제 2, 4-D의 처리가 인삼의 생육 및 근수량에 미치는 영향을 구명하기 위하여 2, 4-D 제초제량 (유제 :70ml/100 /10a, 수화제 : 250g/100 /10a)의 0.5, 1.0, 2.0 배액을 2년, 3년 및 4년생 인삼에 대하여 출아후 40일에 각각 엽면처리아여 경엽의 상육과 장과의 착생 및 근수량의 변이를 조사하고 무처리대조구와 비교 분석하였던 바 그 결과를 요약하면 다음과 같다. 1. 2년, 3년 및 4년생 인삼에 2, 4-D를 일반제초약량의 2배로 경엽산포하여도 지상부의 전체적인 생육상은 무처리구와 차이가 없었으며 특별한 약해현장도 나타나지 않았다. 2. 2년, 3년 및 4년생 인삼에 있어 무처리구와 2, 4-D 유제 및 수화제 처리 농도간에 엽장, 여폭, 경장 및 경직경 등 유의차가 인정되지 않았다. 3. 3년생 및 4년생 인삼의 장과착생수는 2, 4-D 유제를 일반체초제의 2배로 처리한 구에서도 무처리구와의 유의차는 인정되지 않았으며 외관상의 형태에도 전혀 이상이 없었다. 4. 4년생 인삼에 있어 무처리구와 2, 4-D 유제 및 수화제의 처리농도간에 근장, 근식경, 지근수 및 근주의 차이는 인정되지 않았다. 5. 묘삼에 2, 4-D 유제 및 수화제의 일반제초제량을 경엽처리할 경우 줄기가 연화되어 구부러졌으며 특히 수화제 처리시는 잎의 끝이 백화고사되는 약해현장을 나타내었고 구부러진 줄기는 2~3일 후 다시 상향으로 회복되기는 하였으나 이상신장된 결과를 보였다. Weeds may compete detrimentally with the ginseng for moisture and nutrients but hand weeding is the only practical means of eliminating weeds after crop establishment. To define the effects of 2, 4-D herbicide application on the plant growth and root yield of Korean ginseng (Panax ginseng C. A. Meyer). the herbicide 2, 4-D was applied as a foliar spray with the rates of 0.5. 1.0. 1.5 and 2.0 times of the recommended herbicide dosage 70ml/l0a. The Korean ginseng treated with 2, 4-D in the rate of two times concentration was indistinguishable from nontreated plants in visual rating for foliar symptoms. There were no significant differences of the leaf length and width as well as the stem length and diameter in check plants and those recieving 2, 4-D treatments. The. berry maturing in 3 and 4-years old ginseng was not inhibited with 2, 4-D treatment. The root weight of the 4-years old ginseng plant was not reduced by 2, 4-D application of 2 times dosage. However. when the ginseng seedling was treated with 2, 4-D. detrimental phenomena as stem bending and dicoloration of marginal part of seedling leaf were occured but stem bending was recovered in a few days.

This experiment was carried out to obtain some imformations about the ecological variations of the heading time of the newly breeded Indica x Japonica varieties/pedigrees according to the seasonal changes of the seeding date, day length and temperature. The results obtained are summarized as follows; 1) At all varieties, days to heading showed a straight reduction according as the seeding time was delayed. 2) At the group of Japonica varieties, the days to heading of early maturing varieties were much shortened and that of medium or late maturing varieties were little or not shortened under high temperature condition but at the group of Indica x Japonica varieties/pedigrees, days to heading were significantly elongated under high temerature condition. 3) At the group of Japonica varieties, the effect of the short day condition on the days to heading was significantly high at the medium and the late maturing varieties than at the early maturing varieties, however, the short day effect on the reduction of days to heading was not related with the earlyness of each varieties at the group of Indica x Japonica varieties/pedigress. 4) Days to heading of all varieties under the high temperature condition were longer than that under the ordinary culture. On the other hand, the days to heading of Japonica varieties under the short day treatment were shorter than the days to heading of ordinary culture but at the group of Indica x Japonica varieties/pedigrees, the days to heading under the short day treatment were longer than ordinary culture. 5) At both varieties groups, the days to heading at each seeding time were significantly correlated with days to heading at ordinary cultivation. 6) At the group of Japonica varieties, relatively high correlation(p=0.1) was recognized between the days to heading by delay of seeding time, but at the group of Indica x Japonicava rieties/pedigrees, correlation between the ordinary heading date and the shortening rate of days to heading was very low.

고려인삼의 조직배양에 관한 연구 제3보 NAA가 인삼 Callus의 유기 및 기관의 변화에 미치는 영향

曺在星 韓國作物學會 1981 한국작물학회지 Vol.26 No.1

고려인삼의 배 및 기엽조직편에서의 Callus의 유기및 기관의 분화에 지치는 NAA, 2,4-D 및 BA의 영향을 구명하는 한편 인삼의 영양번식방법을 찾고져 본 실험을 수행하였던 바 그 결과를 요약하면 다음과 같다. 1. NAA는 발근에 탁칠한 효과를 보었는데 NAA의 농도가 높을수록 발근량은 증가되었으며 NAA, 2.0mg/l 이상을 첨가한 배지상에서는 줄기의 양단에서 모두 발근하는 경우도 있었다. 2. NAA 4.0ppm까지는 NAA의 정도를 지연시킬수록 Callus의 생장량은 직선적인 증가를 보였으며 엽보다는 기편에서 Callus가 잘 유기되었고 생장도 빨랐으나 Callus의 유기 및 생장에는 NAA보다는 2,4-D가 현저히 효과적이었다. 3. BA는 발근을 억제하는 효과가 현저하였으며, BA 단독으로는 Callus를 유기하는 효과가 전혀 없었으나 BA를 NAA나 2,4-D와 조합처리할 경우 Callls의 유기 및 생장이 배이상 촉진되었는데 Callus의 유기 및 생장을 촉진시키는 교호효과는 NAA와 BA보다는 2,4-D와 BA간에서 현저히 높았다. 4. 배배양에 있어서 NAA 2.0mg/l를 첨가한 배지상에서늘 기의 발생이 현저히 많았던 바 4개 이상의 기이 발생된 개체의 비율이 22.2%였고 8개 이상의 기이 발생된 개체도 있었다. NAA8.0mg/l 첨가한 배지상에서도 기엽은 정상적인 생장을 보였으나 뿌리의 발생량이 아주 많았고 기의 기부에 상당량의 Caillus도 생성되었다. 5. 3매의 소엽이 부착된 기을 1.5cm의 길이로 절단하여 NAA 1.0mg/l를 첨가한 Blayde의 한천배지에 이식하였던 바 기의 기부에서 다수의 뿌리가 발생하여 정상적인 인삼묘를 얻을 수 있었는데 이 실험의 결과는 인삼의 영양번식의 가능성을 명백히 시사하고 있다.량과 재식주수와는 Asymptotic relation을 보였으며 10a당 5,000~10,000주까지는 건엽이 급증하였고, 10.000~20,000주는 그 증가가 수만하며 20.000주 이상에서는 증가율이 더욱 둔화되었다. 따라서 20,000주가 적정재식주수라고 할 수 있다. 7. 수원, 청주, 목포, 제주에서 스테비아 활착과 생육은 양호하였으나 생육성기의 한발은 수량감수원인이 되었다. 정식기가 6월 20일로 늦으면 적기보다 건엽수량이 현저하게 감수되었다. 8. 3월 20일 정식의 보온단일구에서 단일감응으로 건엽수량이 낮았으나 보온 장일 및 보온 자연일장은 보온효과가 크게 나타났다. 4월 20일 이후 안식에서는 보온효과는 인정되지 않았다. 9. Stevioside 함량은 상부엽에서 높았으며 지상 20cm 부위는 현저하게 낮았다 건엽과 Stevioside 수량은 대체로 60~120cm에 집중되어 있었으며 그 집중정도는 품종에 따라 큰 차이가 있었다. 10. 발뢰까지는 수확기를 지연시킬 수록 건엽수량은 현저하게 증가되었으며 발뢰 이후에는 수확기를 지연시켜도 수량 차이는 인정되지 않는다. Stevioside 함량은 발뢰기에 가장 높았고 이보다 빠르거나 늦게 수확할 때 감소하는 경향을 보였다. 건엽수량과 Stevioside 함량을 고려한 수확적기는 발뢰시부터 개화전까지이고 수원 지방에서는 9월 10일~9월 15일경이었다. 11. 영양계의 Stevioside와 Rebaudioside 함량범위는 각각 5.4~l4.3%, 1.5~8.3%로 변이폭이 크며 Stevioside와 Rebaudioside 함량간에는 일정한 경향이 없었다. 저온처리에 의한 임실장해정도와 출수기의 저온처리에 의한 임실장해정도간에는 유의한 정의 상관을 보였으며 또한 저온에 의하여 이삭 추출도가 낮거나 간장단축율이 These experiments were carried out to define the effects of NAA, 2, 4-D and Benzyladenine on the callus induction and the organ differentiation from the explants and to find out the vegetative propagation method of Korean ginseng. The results obtained are summarized as follows; 1. NAA was significantly effective in forming roots from the ginseng stem segment and the number of roots was increased by increasing NAA concentration in the medium. The roots were formed from both distal and proximal ends of the ginseng stem segments grown on the medium containing more than 2mg/L of NAA. 2. The amount of callus growth increased proportionatly with NAA concentration in the range of 4.0mg per liter in the medium. The callus was easly induced from stem segment than leaf segment and 2, 4-D was more effective in callus induction and growth than NAA. 3. The benzyladenine showed the significant inhibition effect in forming roots from ginseng explant. The callus was not induced with BA alone, but in BA and 2, 4-D or BA and NAA added medium, the callus was easily induced and its growth was also accelerated. The interaction effects between 2, 4-D and BA on the callus induction and growth were significantly higher than those between NAA and BA. 4. As the ginseng embryos were cultured on the M.S. medium supplemented with 2mg per liter NAA, number of shoots was significantly increased and the percentage of embryo which had shown more than 4 shoots later was 22.2%. On the medium containing 8mg per liter NAA, the ginseng embryo showed the normal growth of shoots and leaves, but increased roots and callus induction on the basal part of shoots. 5. When the shoots with 3 leaflets were cut in 1.5cm long and grown on the Blayde's medium containing NAA 1.0mg per liter, roots were formed at the proximal end of shoot, and a new ginseng seedling was successfully obtained.

Calculating break-even price of calf production is closely associated with reproductive efficiency. To determine the price, we need data from reproduction records including number of claves weaned, number of cows exposed for breeding, and annual cash coast per cow, and average weaning or market weight of claves sold and retained. Unfortunately, the data were not available in Korea native cow (Hanwoo). To evaluate the performance and the price, we collected calving interval from about 60,000 cows for last 10 years and estimated reproductive performance. Calving interval was increased 4.3% and pregnancy rate was decreased about 1.4∼2.8% year-on-year. Increases in growth rates of number of cow and semen per calf supported the low reproductive performance. Finally, break-even price was calculated using estimated percent calf crop and demonstrated that growth rate of break-even price is larger than that of annual cash per cow, suggesting cow-calf profitability and financial efficiency in Korea native cow (Hanwoo) is getting worse

曹在星,李仁燮 충남대학교 농업과학연구소 1978 農業技術硏究報告 Vol.5 No.2

To information on the inheriance of heading date of rice under the short-day condition, the F_2 seeds obtained from all possible combinations of the diallel crosses between five leading rice varieties: Nongbaek, Tongil, Palgueng, Mangyeong and Gimmaze were grown under the short-day condition and natural condition. The days to heading were investigated and analysed for genetic components. The results obtained are summarized as follows. 1. Under the natural condition, the durations to heading of all combinations excluding Nongbaek x Palgueng and Nongbaek x Mangyeong were longer than those of their parents. mean. Whereas, under the short-day condition, the duration to heading of Mangyeong x Gimmaze combination was equal to that of their parents mean, and those of all other combinations were significantly shorter than those of their parents mean. 2. Under the natural condition, the non-allelic gene interactions were significant in days to heading, but under the short-day condition, the non-allelic gene interactions were not significant, and inheritance of days to heading revealed partial dominace in which additive effects were greater than dominant effects. 3. Tongil and Gimmaze were located on dominant zone under the natural day-length, and Nongbaek and Mangyeong were under the short-day condition. 4. Under the natual condition, dominant effects were greater than additive effects, and both heritabilities of the broad and the narrow senses were significantly low. Under the short-day condition, additive effects were significantly higher than dominant effects, and both heritabilities of the broad and the narrow senses were high.

지역별 HPAI 확산 위험 분석

조재성,김현중 한국농식품정책학회 2023 농업경영정책연구 Vol.50 No.1

In this study, HPAI outbreak data and an epidemiological model were used to estimate the basic reproduction number for HPAI by region, and based on this, the risk of HPAI spread by region was compared, and regional characteristics affecting the difference in risk of HPAI spread were investigated. As a result of the analysis, it was found that the infection spread condition (basic reproduction number of 1 or more) was satisfied in all regions where the HPAI transmission rate was estimated. In addition, it was found that the size of the region and the type of poultry raising in the region had a statistically significant effect on the HPAI transmission rate. Based on the findings, the implications are presented as follows. First, more stricter quarantine measures are needed to prevent the spread of HPAI in areas where basic reproduction number and HPAI transmission rate are consistently high. Second, in order to reduce the risk of HPAI spread, it is necessary to shorten the time from identification of infected farms to culling. Third, it is necessary to further strengthen biosafety in regions with relatively small area, many duck farms and poultry, and many paddy fields.
