뽕나무 花芽의 器內培養에 있어서 生長調節物質이 器官分化에 미치는 影響

南鶴祐,文在裕,金浩樂 한국잠사학회 1988 한국잠사곤충학회지 Vol.30 No.1

Flower buds of the mulberry (Morus alba L., Morus bombycis Koidz.) were cultured under different condition such as basal media. And various concentrations of plant growth substances. Effects of the culture condition on growth of the buds and organ regeneration were investigated and the results obtained are as follows: Murashige and Skoog(M.S) medium was more effective on budding and growth of female (Keomseolppong) and male (Kaeryangppong) flower buds isolated directly from branches, compared to Greshoff & Doy(G.D) and Wolter & Skoog(W.S.) media. The growth of the female buds was promoted at higher concentration of benzyl amino purine(BAP) i.e., 2.0ppm. The female and male buds cultured after cutting for seven days showed better growth than those without cutting treatment. The females and the males bloomed to form healthy stigmas and anthers, respectively, when cultured on M.S media containing high Kinetin with low concentration of indole acetic acid(IAA).

窒素 및 生長調節劑 處理에 의한 뽕나무의 蛋白質, 核酸含量 및 休眠의 變化

柳根燮,南鶴祐,崔營哲 한국잠사학회 1993 한국잠사곤충학회지 Vol.35 No.2

Winter dormancy of the mulberry (Morus species) in Suwon was investigated with regards to mulberry varieties, such as Kaeryangppong, Daeryugppong, Yongcheonppong and Hongolppong application of fertilizers and growth hormone. In general, It initiated at late September and it subsequently became deeper and reached the highest degree through late October to early November. After that early November it gradually turned into the breaking state and was terminated by late November. Intensity and duration of dormancy were lower and shorter in Kaeryangppong. The standard application of N. P. K(30-13-18 kg/10a) affects it delayed, but terminated earlier. On the other hand, the double amount of nitrogen affects the dormancy fast, but terminated late. The treatments of GA3 at the early and termination stages increased the bad sprouting. The contents of RNA and protein in the bark gradually increased as the dormancy becomes deeper.

New triploid mulberry cultivar, Suilppong was bred among selected lines from F$_1$ seedlings obtained by crossing the female, artificial tetraploid No. 411 which obtained from Chungilppong seedlings, and the male, Kugsang 21. Local adaptability test has been carried out at four places (Suwon, Kongju, Jeonju and Jangsung) for five years since 1997. Leaf quality was tested by silkworm rearing for two silkworm rearing seasons (spring and autumn) at Suwon in 2000. Suilppong was recognized to be superior in productivity to control cultivar, Kaeryangppong. The new cultivar, Suilppong, has following agronomic characteristics as compared with Kaeryangnppong, which is leading cultivar widely cultivating in Korea. It is belonging to Morus alba L. with mixed shapes from the ovate to 5 lobated leaf shape, sprouting in spring nearly the same to the Kaeryangppong (Morus alba L.), high leaf yielding of 20% compared to Kaeryangppong (Morus alba L.). It is adaptable to everywhere except the places where cold damage occurs frequently in Korea. Suilppong is recommended to rear silkworms not only in spring but also in autumn besides for young silkworms. 잠상 123호를 수원, 공주, 전주와 장성 4개 지역에서 수행한 지역적응시험 결과, 수량성이 높고 엽질 등이 우수하여 2001년 수일뽕으로 명명하여 장려품종으로 지정하였으며 그 주요 특성은 다음과 같다. 1. 청일뽕 자연교잡 실생에 콜히친 처리하여 얻어진 4개체 411호와 국상 21호를 교배하여 얻어진 3배체로 백상형 (Morus alba L.)에 속하는 암나무이다. 2. 수형은 직립성이고 개량뽕에 비하여 가지수는 큰 차이가 없으며, 평균가지 길이와 마디사이길이는 짧고 가지 굵기는 굵다. 3. 발아기는 중뽕이며, 잎의 크기는 대형으로 잎두께는 약간 두꺼우며 타원형과 3-5열엽이 섞여 존재하지만 5열엽이 많다. 3. 뽕 수량은 개량뽕보다 20% 많으며, 사료가치는 청운뽕과 같은 수준으로 비교적 우량하다. 4. 뽕나무 오갈병 저항성은 개량뽕보다 약간 약하나, 눈마름병, 줄기마름병 및 축엽세균병은 개량뽕과 비슷한 수준이다. 5. 춘추잠기 겸용 큰누에용 뽕으로 동해상습지를 제외한 전국에 재배할 수 있다.

Monascus sp. J101을 이용한 적색색소의 Extractive Fermentation

주재영,남학우,윤주천,신철수 한국산업미생물학회 1994 한국미생물·생명공학회지 Vol.22 No.1

Monascus sp.의 변이주인 색소생성능이 높은 Monascus sp. J101을 이용한 적색색소 생산의 발효특성을 분석하고 extractive fermentation을 시도하여 색소의 생산성을 높이고자 하였으며 Amberlite XAD-7 resin을 첨가한 경우에 대한 동력학적 분석을 수행하였다. Monascus sp. J101이 생산하는 적색색소는 균체의 색소의 생산량이 총 색소생산량의 약 17%에 해당하였으며, 색소의 생산은 product에 의해 regulation되는 것을 확인하였다. 한편, 균체의 생육은 48시간부터 정지기에 도달하였으나 색소의 생산은 그 이후에도 계속되어 mixed growth-associated의 양상을 보였다. 균체의 배양중에 permeabilizing agents를 첨가하여 extractive fermentation을 수행한 결과, 배양 48시간에 Triton X-100 0.05%를 첨가했을 때 약 18%의 색소생산의 증가를 보였으며, ethyl acetate를 0.25% 첨가한 경우는 약 12%, deoxycholate 0.05%인 경우는 약 15% 증가하였다. 균체의 배양중에 nonionic adsorbent인 Amberlite XAD-7을 첨가하고 extractive fermentation을 행한 결과, 배양 48시간에 Amberlite XAD-7을 12.0% 첨가하였을 때 첨가하지 않은 control에 비해 색소의 생산이 약 48.9%가 증가하였다. The characteristics of monascus fermentation using a hyperpigment-producing mutant, Monascus sp. J101, were analyzed, and the extractive fermentations employing permeabilizing agents and resin were carried out to increase the productivity of red pigment. And the kinetic analysis was also carried out in case of the monascus fermentation using Amberlite XAD-7. The extracellular content of the red pigment produced by Monascus sp. J101 was about 17% of the total, and the production of pigment was regulted by its own product. The cell growth reached a stationary phase at 48 hours after inoculation, whereas the pigment production continued up to 110 hours, which showed the pattern of a mixed growth-associated type. During the fermentation, various permeabilizing agents were added to the culture medium and their effects on pigment production were examined. By adding 0.05% Triton X-100 at 48 hours of cultivation, about an 18% increase in pigment production was accomplished as compared to the control, 12% for 0.25% ethyl acetate and 15% for 0.05% deoxycholate, respectively. When a nonionic adsorbent, Amberlite XAD-7 was added to theh culture medium at a concentration of 12.0% at 48 hours of cultivation, the pigment production was enhanced by about 48.9% as compared to the control.

성규병,김현복,남학우,이상욱,구태원,박광준,김호락 한국잠사학회 2001 한국잠사곤충학회지 Vol.43 No.1

New Mulberry Cultivar, Milsungppong, was selected from Fl seedlings obtained by crossing the female, 4X Keomseolppong, and the male, Kaeryangppong. Local adaptability test has been carried out at five Places(Suwon, Chunchun, Cheongju, kongju and Sangju) for four year since 1992. Leaf quality was tested by silkworm rearing for two sildworm rearing seasons(spring and autumn) at Suwon in 1995. From these tests, Milsungppong was found to be superior to control cultivar, Kaeryangppong, in productivity, footability and shoot cold injury. The new cultivar, Milsungppong, has following agronomic characteristics as compared with Kaeryangppong, the most prevailing cultivar in Korea. It is triploid cultivar belonging to Morus bombycis KOIDZ with the leaf shape of five lobes, sprouting in spring nearly the same to the Kaeryangppong (Morus alba L.). high leaf yielding of 25% compared to Kaeryangppong (Morus alba L.) and the medium degree of cold resistance. It is adaptable to every where in Korea except the area cold injury broken out habitually. Milsungppong is recommended to rear silkworms not only in spring but also in autumn besides for young silkworms.

박광준 ( Kwang Joon Park ),남학우 ( Hack Woo Nam ),이종택 ( Jong Tack Lee ) 한국잠사학회 1983 한국잠사곤충학회지 Vol.25 No.1

全原一號 品種은 1920年代 後半에 全北 原蠶種製造所에서 選拔하였으며, 1970年代 中盤까지 湖南一部 地方에 栽培되였었다. 本 品種의 正確한 特性 究明을 위하여 1977年에 水原과 全州에 改良뽕을 對照品種으로 全原一號 品種을 植栽供試하고 1979年부터 1982年가지 4個年間 栽培試驗을 實施하여 究明된 特性은 다음과 같다. 1) 全原 1號는 白桑系에 屬하는 中生種이다. 2) 枝條는 展開性, 條數型으로 伸張力이 弱하다. 3) 枝條의 枯損長比率은 改良뽕보다 약간 높으나 큰 차 없었으며, 뽕나무 오갈병저항성과 耐倒伏性은 改良 뽕보다 弱하다. 4) 年間改量은 正葉量으로 10a當 1,474kg으로서 改良보다 14% 적었다. The mulberry variety, Jeonweon No. 1, has been cultivated in some parts of Ho-Nam District since the variety was selected at the Jeonbuk Provincial Silkworm Egg Production Station in the latter half of 1920s. However, the characteristics of the variety have not been reported. Therefore, the cultivation experiment on the variety was carried out to investigate the characteristics of the variety at Jeonju and Suweon for four years from 1979 to 1982. 1. The mulberry variety, Jeonweon No. 1, belongs to the Morus alba L. and the sprouting stage is medium. 2. The branch growth of the variety was rather slow, however the number of branches was more and the posture of branches opened wide. 3. The rate of cold injury of shoot tips was a little high, but resistance to disease and the lodging of branches was weaker, compared with the Gaeryangbbong variety. 4. The annual yield of leaves of the variety per 10a was 1,474kg, 14% less than that of the Gaeryangbbong variety.
