  • This research was carried out to produce rainbow-colored roses from white cut rose, Rosa hybrida 'Denice', to meet customers' desire of having various colors of roses. The higher temperature of dyeing solution used, the faster coloring time surveyed. In high temperature, the flowering speed of cut flower accelerated and after treating more than 4 hours, the edges of flowers became too dark or dry. In the condition of concentration of dyeing solution, $11g{\cdot}L^{-1}$ dyed faster than $7.5g{\cdot}L^{-1}$, however, no differences between $15g{\cdot}L^{-1}$ and $11g{\cdot}L^{-1}$ have observed. It looked fast coloration at the stage of early blooming, but all three different petal opening stages need similar time to get even coloration from outer to inner petals. For the consideration of commercial value, flowers with 3-4 petals opened are better quality than flowers with less petals opened. It was possible to make rainbow-colored rose by dipping 'Denice' with 3 primary color combination, Hot Pink, True Blue, and Yellow dyes, at the best result conditions of $20^{\circ}C$ solution temperature, 3-4 petals opening stage, 11g/L concentration of dye solution and 3 hours dipping, respectively.

  • A pathogen that causes a new disease on green pumpkin in the nursery and the field was characterized and identified. Symptoms of the disease on green pumpkin were water soaking lesions and spots with strong yellow halo on leaf, brown lesion on flower, and yellow spot on fruit. The bacterial isolates from the leaf spot were pathogenic on the 8 curcubitaceae crop plants, green pumpkin, figleaf gourd, wax gourd, young pumpkin, zucchini, cucumber, melon, and oriental melon, whereas they did not cause the disease on sweet pumpkin and watermelon. They were Gram-negative, rod shape with polar flagella, fluorescent on King's B agar and LOPAT group 1a by LOPAT test. Their Biolog substrate utilization patterns were similar to Pseudomonas syringae pv. syringae's in Biolog database. Phylogenetic trees with 16S rRNA gene sequences and multilocus sequence typing (MLST) with nucleotide sequences of 4 housekeeping genes, gapA, gltA, gyrB, rpoD and those of P. syringae complex strains in the Plant Associated and Environmental Microbes Database (PAMDB) showed that the green pumpkin isolates formed in the same clade with P. syringae pv. syringae strains. The clade in MLST tree was in the genomospecies 1 group. The phenotypic and genotypic characteristics suggested that the isolates from green pumpkin lesion were P. syringae pv. syringae.

  • This study identified a new male-sterile germplasm of Chinese jujube, named male-sterile No. 2 (JMS2), and achieved controlled hybridization using that germplasm as the female parent. The anthers of JMS2 before flower bud opening became shrunken, dingy yellow and much smaller than normal ones, and they changed to brown after anthesis. No pollen was observed in anthers of JMS2 and its male-sterile trait remained stable over different years. A total of 1,642 fruits were obtained from ten intra- and interspecific cross combinations via controlled hybridization from 2008 to 2012 using JMS2 as the female parent. Of those, 27.3% produced seeds, on average (0-72.6%). The rate of fruit with seed (RFS) was significantly different between cross combinations or years. Compared to other cross combinations, the RFS in the combination of JMS2 ${\times}$ 'Xingguang' (a Chinese jujube cultivar with high resistance to jujube witches' broom disease) and JMS2 ${\times}$ 'Xing16' (a sour jujube genotype) remained high in different years and reached means of 48.7 and 58.1%, respectively. Finally, 150 plantlets were regenerated from immature embryos, and 51 of them were randomly selected and identified to be authentic hybrids using amplified fragment length polymorphism (AFLP) markers. This is the first report of hybrids obtained from a cross between Chinese jujube and sour jujube.

  • Seeds of medicinal soybean [Glycine max(L.) Merill] are characterized by a black seed coat, white stripe at hilum border, yellow cotyledon, and very small seed weight. Production of this medicinal soybean has recently increased as a consumption increased. The objective of this study was to evaluate the growth characteristics and seed yield of collected medicinal soybeans and to obtain basic information on production practices and breeding materials. The collected medicinal soybean lines were cultivated at three locations for two years. Twenty-seven lines were planted at the Research Farm, Korea University, Namyangju city, on May 23, and at the Research Farm, Kyungpook National University, Taegu, on May 20, 1995. In 1996 field experiments, forty-four lines were planted on May 25, at Research Farm, Korea University, and twenty-seven lines among those were planted on June 7 at the Research Farm of National Yeongnam Agricultural Experiment Station, Milyang city. The investigated lines had purple or white flower. Flowering and maturing dates were similar or later than those of the control cultivars. Branch number was greater for the investigated lines. One hundred-seed weight of the lines ranged from 8.5 to 15.0 g. Mean seed yields ranged from 1.54 to 2.89 MT/ha. Nine lines of the investigated medicinal soybeans showed higher yield capacity than the control cultivars. Further research should be done on the improvement of the production system and breeding program of medicinal soybeans.

  • Distribution analysis on natural habitats for the genus Calanthe in Mt. Halla of Cheju province revealed that C. discolor and C. sieboldii were found mostly in the range of 120~400 m and 300~600 m above the sea level, respectively. C. bicolor was found in 300~400 m where both C. discolor and C. sieboldii were overlapped. The present morphological assessments showed that C. discolor had the smallest sizes of leaves and floral parts, C. had the largest, while C. bicolor had the intermediate between the above mentioned two species. Flower colors of C. discolor were brownish red and simple white, and that of C. sieboldii was merely golden yellow, whereas C. bicolor had a diverse mixed colors originated from the other two species. The specific distribution of natural habitats and morphological characteristics of three Calanthe species led the suggestion that C. bicolor can be regarded as new species derived originally from natural hybridization between C. discolor and C. sieboldii.

  • This study explores the types, shapes and changes of the court dance garments of mudong[child court dancer] and yeoryeong[female court dancer] for court dances such as Jangsaengboyeonjimu, Yeonbaekbokjimu, Jesuchang, and Choehwamu, and the arrangement of colors in their garments. The conclusion of the study is as follows: First, the type of garments of mudong varied according to the type of dance, role of mudong and passage of time. In all four jeongjae's, hongpo[red robe] and baekjilheukseonjungdaneui[white under garment trimmed in black] were commonly found. Second, the dress of yeoryeong in the Jangsaengboyeonjimu, Yeonbaekbokjimu, Jesuchang and Choehwamu was that of other yeoryeong, which was basically comprised of hwagwan[flower headdress], hwangchosam[yellow robe], hongchosang[red skirt] and sudae[embroidered belt]. Third, the color schemes of the court dance garments used in Jangsaengboyeonjimu, Yeonbaekbokjimu, Jesuchang and Choehwamu revealed that the color arrangement of sangsaeng [mutual generation] of the Ohaeng[Five Elements] scheme were favored in the garments of mudong and yeoryeong. The dress of mudong is characterized by sangsaeng between top and bottom, and between total and part, while the color scheme of the outer and inner was sanggeuk[mutual overcoming]. As for yeoryeong, the color arrangement was of sangsaeng in top and bottom, outer and inner, and total and part, but in the five-colored hansam[sleeve extension], both sangsaeng and sanggeuk were found.

  • African marigold is a common plant easily available in many flower beds. It has been reported as a practical and prospective resource of dyes since the dyes can be extracted from their bodies as well as petals. In this research, cotton and ramie fabrics which are made from natural cellulose were dyed using the extract of the African Marigold which is a variety of marigold. Dyeing tests were carried out under different pH of the dye solution and mordants. Dyeability was evaluated by examining and measuring surface color, K/S value, and the changes in the maximum absorption wavelength. The probability of improving dyeability was investigated by pre-mordanting with pre-treated chitosan. For the dyeing with marigold extract, the color tone did not differ by pre-mordanting and non-mordanting. Reaction with post-mordanting was excellent, which was colored in various yellow series. The best dyeability was achieved in dye solution of pH 6.5-7.0 which is not conditioned. The largest K/S value and color difference were obtained in tin mordanting. The dye uptake was greatly increased in chitosan pre-treated mordanting compared with the post-mordanting without chitosan pre-treatment. Due to its high heat resistance, African Marigold extract is easy for dye extraction and dyeing, and its dyeability is excellent for natural cellulose fibers. Also, colorfastness was proved to be practically usable.

  • Korean fashion designs became important items in Korea in the middle of the 1980s, and it has advanced into the world market in the early part of the 1990s. To achieve success in global fashion world, it is necessary to analyze Korean fashion design thoroughly and prepare strategies to develop designs with mainstream acceptance in the global fashion world. The purpose of this study is to analyze the aesthetic characteristics and Korean beauties of Korean fashion designs. Fashion photos of Korean fashion designs from 2006 S/S to 2012 F/W were analyzed. 357 designs from 608 designs of 4 representative Korean designers were examined and design characteristics, expression styles were studied. The major conclusions of the study are as follows : 1. H Line, slim, fitted silhouette and loose look were applied. 2. 5 major traditional colors, red, blue, yellow, white and black colors were used. Brown color, neutral color, golden color and beige color of the textile material's original color were used. Traditional textile materials like ramie fabric, satin and cotton, wool and metallic fabric were used. 3. Patterns of flower, traditional pattern and Korean letters were applied. Embroidery, patchwork and mother-of-pearl were decorated. 4. The three types of beauty were natural beauty, moderate beauty and decorative beauty. The types that were analyzed were realistic expression type, moderate expression type, image expression type and mixed expression type. To be accepted in global fashion world, Korean traditional design elements should be modified, broken down and reorganized so that Korean fashion design can be recreated.
