沈慶久,安永熙,柳美先,劉鍾勳 成均館大學校 科學技術硏究所 1985 論文集 Vol.36 No.1

Aristolochia manshuriensis KOM. distributed in the northern parts of Kangweon Province centering Mt. Seorag in Korea is a vigorous and climbing vine. It has been used widely as one of ingredients of chinese medicine. The unusual flowers by virtue of their shape and hue are beautiful, flowered in May and matured in October. The large leaves are coarse in texture, and have been used as arbor, trellis, pergola, and pillar. Therefore, it is now considered as an excellent ornamental plants for Landscape. The objectives of this study were investigation of the suitable propagation methods, comparison of the influence of bed temperature for hardwood cuttings, and determination of the effectiveness of various rooting promotion treatments. The results obtained were as follows. The germination rate 53% when the period of stratification was 70 days. The rooting percentage, rootlet number, and length of root male plants are generally better than those of female plants. The female and male plants cuttings tended to have the largest root system in the 20℃-bed temperature. The female plants treated with 20℃, IBA 1000ppm and 25℃ IBA 1000ppm. The male plants treated with 20℃, IBA 500ppm rooted well.

Bittersweet(Celastrus orbiculatus) grown widely in the mountains of Korea is perennial, deciduous and climbing plant. They have strong vines, flower from May to June and mature in October. The red coloured fruits are beautiful, use as the cut-flower materials, and also as the food of birds. This is now considered worthwhile to exploit as an outstanding landscape plant. The objectives of this study were investigation of the suitable propagation methods, reaffirmation of the utility of mist room for softwood cuttings, influence of bed temperature for hardwood cuttings, and determination of the effectiveness of various rooting promotion treatments. The results obtained were summarized as follows. The germination rate was 70% when the period of stratification was 50 days. In softwood cuttings, the rooting percentage and rootlet number tended to be greater in closed moist chamber than those in mist rooms. The rooting percentage, rootlet number and length of root in the 25℃-bed temperature were higher than those in the bed of 20℃ or 30℃ in hardwood cuttings. Cuttings treated with IBA 1000ppm rooted better than those received other hormone treatments in hardwood and softwood cuttings.

沈慶久,柳美先,李貞植 成均館大學校 科學技術硏究所 1986 論文集 Vol.37 No.1

This study was carried out to accelarate the growth of rhizome and shoot formation of Cymbidium kanran. Rhizome used as materials were prepared by seed strile culture and rhizome-tips were placed on the basal medium (Murashige & Skoog) which were supplemented with growth substances. The results obtained were summarized as follows: 1. Shoot formation at the rhizome-tips was the best in the media supplemented with 0-0.1mg/l BA. Rhizome growth was stimulated in the media supplemented with 0.1mg/l NAA and 4-8mg/l BA. 2. When organic matters were added to basal medium, a noticeable promotion of rhizome growth was observed in the medium containing activated charcoal. 3. The growth of rhizom was promoted when 4% sucrose, 3g/l pepton, or 4g/l yeast extract were added to basal medium. 4. Incorporation of 1.0mg/l BA and 10^-3M L-arginine, L-aspartic acid stimulated shoot formation remarkably under light condition. 5. Growth of rhizome according to light or dark treatment was better under dark than under 16hr illuminated light condition and the rhizome cultured under dark condition was more effective for shoot formation.

Yoo Kyung Seon,Suk Jung Kim,Joo Hyeong Lee,Hye Rim Kang,Eun Ju Yang 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

The purpose of this study was to evaluate the antioxidant content and activity of naked oat cultivar ‘Choyang’ according to germination condition. The antioxidant content and activity of naked oat were significantly increased after germination compared to raw naked oat. The effect of steeping time (4, 8, 16 h) on antioxidant content and activity of germinated oat was investigated. Total polyphenol and flavonoid contents and antioxidant activity (DPPH and ABTS radical scavenging activities and FRAP value) substantially decreased with increasing steeping time. This study further investigated the effects of germination temperature (20℃, 25℃, and 30℃) and time (24, 48, and 72 h) on antioxidant content and activity of germinated oat. Total polyphenol and flavonoid contents and antioxidant activity increased with increasing germination temperature and time. This work was supported by the Korea Institute for Advancement of Technology (KIAT) grant funded by the Korea Government’s Ministry of Trade, Industry and Energy (MOTIE) (No. P0017618).

Effect of the Dietary Supplementation of Cassava by-product on Meat Quality in Pork

Yoo Kyung Seon,Ye Seul Seo,Mi Ae Bang 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

This experiment was conducted to investigate the dietary effects of Cassava by-product (CBP) on meat quality in pork. Growing swine were randomly divided into 3 groups (T0: Commercial diet feed; T3: Commercial diet+ 3% CBP; T6: Commercial diet+ 6% CBP). The meat quality of pork loin were evaluated by proximate composition, pH, drip loss, cooking loss, textural properties and sensory evaluation. The proximate composition, pH and drip loss were not significantly different among the control and treatment group. The cooking loss revealed significantly lower in T6 group than in others (P<0.05). In case of textural properties of boiled pork, shear force, springiness, cohesiveness, gumminess and brittleness were not significantly different among the control and treatment group, whereas hardness was significantly lower in T6 group (P<0.05). In sensory evaluation, the flavor, off-flavor, off-oder, tenderness, juiciness and overall acceptability of boiled pork revealed significantly higher in T6 group than in others (P<0.05). As a result, dietary supplementation of CBP could be recommended for the production of high quality meat.
