소득작물 및 시설재배 후작 벼 안전재배를 위한 묘 종류별 생육특성 및 수량성에 관한 연구결과를 요약하면 다음과 같다. 1. 이앙당시 엽수는 중묘대비 성묘는 1.2배가 많았다. 2. 묘의 발근력은 어린모>중묘>절엽묘 순으로 좋았다. 3. 분답 초기생육 기간동안에 초장은 중묘가 가장 길었으며 엽수는 성묘가 높은 엽령을 유지하였다. ㎡당 분열수는 성묘가 가장 적으면서 조기에 경수를 확보하였으며 건물중은 분얼이 적었던 성묘가 가벼웠다. 4. 출수기는 중묘대비 성묘가 3일 빨랐고 어린모는 8일이 늦었다. 5. 간장은 73~80㎝묘령이 클수록 짧았고 ㎡당 수수는 어린모와 성묘가 많았으며 등숙비율은 묘령이 클수록 높았다. 6. 10a당 쌀수량은 ‘99년에서 ’01년까지 평균수량은 422~441㎏으로 통계적 유의차는 없엇으나 성묘>중묘>어린모순으로 많았다. 7. 미질은 현미의 품위를 보면 완전미 비율이 성묘에서 높았고 백미품위도 성묘에서 높았는데 단백질 및 아밀로즈함량은 묘종류별로 차이가 없었다. This experiment was conducted to investigate the rice seedling types suitable for safty cultivation after economic crops cultivation in paddy field. In rice seedling transplanted on July 5 heading date is three days earlier in 40-day old seedling with cutting 1/2 leaf on 20 days than 30-day old seedling. Also, 40-day old seedling has highest for ripening ratio among seedling types, which lead to high yield. Milled rice yield per 10a is the highest, but not signigicant. Perfect kernel ratio of brown rice is the highest in 40-day old seedling although amylose and protein contents in milled rice are similar to other seedlings types

최근 개발된 수진벼의 중묘의 기계이앙재배시 실비생략에 따른 수량 및 미질에 영향에 관한 연구결과를 요약하면 다음과 같다. 1. 출수기의 건물중의 기관별 분포비율에 있어서는 분시방법간 비슷하여 기관 구조에서는 차이가 없었다 2. 분시발법별 수상에 있어 2차지경 및 영화퇴화율은 수비 30%를 준 기비 50%-분얼비 20%- 수비 30% 및 기비 40%-분얼비 30%-수비 30% 분시구에서 가장 낮았다. 3. 분시방법간에 출수기는 8월 16일로 동일하였고 간장 및 ㎡당 수수가 비슷하였으며 수당립수 및 등숙비율이 차이를 보이지 않아 쌀수량도 502~51 8㎏/10a('00) 및 563~601㎏/10a('01)로 비슷하였다. 4. 2년간 평균 현미의 완전미비율은 72.8~76.2%('00) 및 80.3~83.3%('01)로 차이가 없었고 백미의 정상립 비율은 76.3~79.6%로 비슷하였으며 아밀로즈 및 단백질함량은 각각 18.9~19.2% 및 7.1~7.2%로 비슷하였다. This experiment was conducted to evaluate a proper nitrogen spilling method in machine transplanting, especially in no fertilizing effect at grain filling stage of rice. The results obtained are as follow; Rice growth characters such as heading date, culm length and panicle number per ㎡ did not differ with nitrogen application methods either basal (50% )-tillering stage (30%)-panicle initiation stage (20%) or the basal (40%)- tillering stage (30%)-panicle initiation stage (30%) compared with the recommended nitrogen application method, basal (50%)-tillering stage (20%)-panicle initiation stage (20%)-heading stage (10%). Also, perfect kernel ratio and milled rice yield per 10a as well as rice quality were similar among nitrogen spliting treatments. The result indicates that the nitrogen fertilization at the ripening stage is not necessary.

유용욱,이미성,차정단,김기경,신상희,문상은,김강주 원광대학교 생명공학연구소 1999 생명공학연구소보 Vol.6 No.1

Staphylococcus lugdunensis (S. lugdunensis) is a newly identified pathogenic species of coagulase negative staphylococci and an occasional but not rare cause of severe infections, such as infective endocarditis after dental extraction, bacteremia, osteomyelitis, peritonitis, and soft tissue infections. As antibiotic use increased, resistance rapidly developed. Some strains have plasmids related to antibiotic resistance. To characterize S. lugdunensis in acute oral infection, S. lugdunensis was isolated from the patients with acute oral abscess, osteomyelitis, and normal persons. Antibiotic resistance, in vitro cellular toxicity, in vivo virulence, δ-like hemolysin activity, and synergistic hemolysis on sheep blood agar plates were investigated. The dot blot analysis and Southern blot analysis of staphylococcal DNA was performed with δ-hemolysin gene probe of Staphylococcus aureus. (S. aureus) Staphylococcal DNA was cloned, nucleotide sequence was analysed, and homology was compared with other sequence in Gene Bank. S. aureus, S. lugdunensis, Staphylococcus cohnii (S. cohnii), and other coagulase negative staphylococci (CNS) were isolated from the patients with acute oral infection. The isolation ratio of S. lugdunensis in the patients with infection was higher than that of healthy persons, but the isolation ratio of S. aureus in the patients with infection was similar to that of healthy persons. S. lugdunensis from the patients with acute oral infection showed the resistance to penicillin, methicillin, cephalothin, and clindamycin. S. lugdunensis in the patients had cellular toxicity in vitro and virulence in vivo. All strains of S. lugdunensis had δ-like hemolysin activity against rabbit erythrocytes. Four of the six strains of S. lugdunensis gave synergistic hemolysis with S. aureus on sheep blood agar plates. In dot blot analysis, all strains of S. lugdunensis showed the positive reaction with the probe of δ-hemolysin gene in S. aureus, but a 7.3 kb HindⅢ fragment was observed in the DNA of S. lugdunensis that gave synergistic hemolysis in a Southern blot analysis. The molecular size of partially purified δ-hemolysin was about 50 kd. The cloned fragments from the chromosomal DNA of S. lugdunensis showed the partial homology with the insulin receptor-related and dopamine receptor of humans. These results suggest that S. lugdunensis might be an important pathogen in acute oral infection and show some homology with eukaryotes.

보리후작 벼 부분경운직파기의 포장성능 평가와 벼 생육 및 수량영향을 조사하기 위해 실시한 연구결과는 다음과 같다. 1.부분경운직파 시작기의 파종시 종자 떨어짐 및 복토상태는 양호하나 배수골 넓이 및 깊이가 각각 17㎝, 10㎝로 좁고 배수골 양쪽벽이 무너져 배수골 안에 흙이 쌓이는 경향이었다. 2. 출아일수는 부분경운직파는 12일로 요철골직파보다 2일 늦었고, 입모수 및 파종 25일후 초장 변이계수는 부분경운직파가 요철골직파보다 큰 경향이었다. 3. 출수기는 부분경운직파는 8월 26일로 요철골직파보다 3일 늦었으나, ㎡당 수수, 수량구성요소 및 10a당 쌀수량은 요철골직파 및 부분경운직파에서 비슷하였다. 4.부분경운직파는 요철골직파에 비해 줄기매몰심이 깊고 도복지수가 낮아 요철골직파보다 도복이 적었다. Performance of minimum-tillage direct seeder and effect of the minimum-tillage direct seeding method on growth and yield of rice under barley-rice double cropping system was investigated. Seeding status of the minimum-tillage direct seeder was acceptable except for narrow irrigation canal formation and demolish of the seeding row in the barley straw added plot. In the minimum-tillage direct seeding, rice seedling emerged at 13 days after seed sowing, 2 days late compared with the corrugated dry furrow seeding method. The high variation in the seedling stand and seedling height at 25 days after seeding was occurred in the minimum-tillage direct seeding as compared with that of the corrugated dry furrow seeding. However, occurrence of the field lodging in the minimum-tillage direct seeding was lower than the corrugated dry furrow seeding method due to deep culm burial depth. Based on the milled rice yield, the two direct seeding methods showed similar with 432 ㎏ per 10a.

This experiment was carried out to examine ecological response and soybean quality as affected by environmental cultivation for producing high seed quality in domestic soybean variety. The results are as follows: Under equal cumulative temperature condition, soybean plants grown in Muju showed longer days to flowering, which was an effect of the long day-length on high latitudes, and longer duration of reproductive stage as a result of low temperature within that period. Considering apparent seed quality, 100 seed weight of soybeans grown in Muju was heavier than Miryang. Ratio of seed crack and disease-damaged seeds was lower in Muju, and these parameters decreases as planting was delayed. The protein contents did not show significant difference in terms of altitude and planting date, however, crude oil contents were higher in Miryang. An opposite trend was observed in C18:1 and C18:3. In the fatty acid composition, the proportion of C18:1 decreased as seeding date was delayed, and was higher in Miryang. Opposite observations were obtained from C18:3. The anthocyanin contents were highest on June 10 planting and higher in Muju than in Miryang. Isoflavone content was higher as seeding date was delayed and is similar accross seeding dates in Muju. As a summary, for high seed quality production the optimum planting date was June 10, and Muju was more suitable region than Miryang.

overgrowth of soybean plants and thereby brings about lodging, decrease in pod number, damage by disease and insect pest, etc. This experiment was carried out to investigate optimum decapitation method in vinyl mulching soybean cultivation. Sinbuseoktae, local soybean variety was sown on May 25 and June 15 in 2009. Decapitation treatments(Non-decapitation, V8 stage-stem, V8 stage-apex, Flowering initiation stage, V8 stage-Stem+Flowering initiation Stage) were practiced on major growth stage on May25 seeding. Lodging did not occur in apex decapitation at V8 stage while other treatments had severe lodging. NAR from R5 to R7 stage was also highest in apex decapitation at V8 stage, which meaned optimum plant organ structure in utilizing light. On the other hand, flowering date and maturity date among treatments were similar. Seed yield in apex decapitation at V8 stage was highest with 274kg/10a, followed by flowering initiation stage with 249kg/10a. The apex decapitation at V8 stage had 26% yield increase as compared with the control of 216kg/10a due to heavy 100-seed weight.
