  • This study was carried out to investigate the effects of nutrient solution concentration, irrigation frequency on growth, flowering, and cut flower longevity of Dendranthema grandiflorum (Ramat.) Kitamura 'Shuhouno-chikara' hydroponically grown in perlite media. Not only stem length but also mineral contents of each plant organ in nutrient solution culture were much higher than those in soil culture. 1/2S of nutrient solution was good at early stage, but 1S of nutrient solution was better as chrysanthemum growth progressed. Among different concentrations of nutrient solution, mineral contents of each plant part showed no significant difference. 1S treatment of nutrient solution increased the vase life by 3 days than 2S treatment. The growth and mineral contents of each plant organ were great in plants irrigated 8 times a day, because of high moisture contents of medium and high water availability, followed by more frequent nutrient replenishment near roots. There was no correlation between nutrient solution concentration and vase life of cut flower grown in nutrient solution culture. Cut flowers irrigated twice per day had the longer vase life than other treatments (4, 8 times).

  • This is a study on the flower pattern artwork of the west wall of the Jagyeongjeon in Gyeongbokgung to find out the type of plants and flowers represented and their symbolism. The research was conducted from July 2010 to March 2011 and the artwork classified on the basis of its horticultural traits. A number was assigned to each pattern for analysis: No. 1 is Prunus mume, No. 2 is Prunus persica, No. 3 is Paeonia suffruticosa, No. 4 is Punica granatum, No. 5 and 6 is Dendranthema grandiflora, No. 7 is Rhododendron mucronu and No. 8 is Phyllostachys bambusoides. These 8 flower patterns symbolize longevity and fecundity and their presense around the Jagyeongjeon helped to bestow good fortune on the royal family so that they might live long lives and bear many children. 4 artworks symbolize longevity, 2 artworks symbolize integrity and 1 artwork symbolizes wealth and happiness. There is also symbolism of the need to have constancy in a royal household even during secular change. Out of the 8 artworks, the imagery of a bird and a moon is represented only once, but the image of a butterfly is represented five times in the surrounding elements. The bird and butterfly symbolise freedom and happiness from free love. Women in the palace are like a butterfly wanted to be like love as a freedom and have a free and open relationship like a butterfly. But a harmonious relationship between the royal family wanted to have a symbolic meaning that could be seen of the symbolistic. Based on the "Yangwhasorok"only plants with the highest values, from the 1st and 2nd grades, were used in the artwork of the west wall of the Jagyeongjeon.

  • The study was conducted to investigate the characteristics of flower quality and yield of gerbera 'Sunny Lemon' by mutrient solution strength and media of nutrient solution. The plant growth of 'Sunny Lemon' showed the highest values in the media of rockwool and perlite 1: peatmoss 2. Especially the yield of cut flowers for a year was more than 60 flowers and the flower longevity was over 10 days irrespective of nutrient solution concentration in the two media. There were no significant differences of plant characteristics in the nutrient concentration of 1/2 and 1 times, and the mineral nutrient contents showed similar values. Therefore, we recommended the media of perlite1: peatmoss2 with the concentration of 1/2 times for economical use. The rockwool media was not appropriate because of the weak buffer capacity like EC and pH.

  • Chitooligosaccharide (COS), as antioxidant, extensively applied to food and juice preservation. In the present study, influences of COS on vase life and ornamental value of cut roses were investigated. Results showed that vase life of cut roses treated by COS was longer 6.4 days than one of control and ornamental character of cut roses was improved effectively by COS. The increase of vase life and ornamental value were chiefly governed by that COS improved water absorption capacity of cut roses. Besides that, COS decreased the contents of superoxide anion and hydrogen peroxide and lowered the levels of malondialdehyde in turn during the senescence process of cut roses. That was because that COS not only enhanced activities of antioxidant enzymes glutathione reductase, but also improved reduced glutathione contents in petals of cut rose. Therefore, COS could be used in commercial preservatives to improve the longevity of cut roses.

  • This study was conducted to examine characteristics of rhizome growth and flowering of white lotus (Nelumbo nucifera) plant in Muan Hoesan-lake for collecting the basic data on the cultivation and the flowering which is growing in Muan Hoesan-lake of Jeonnam province in Korea. We have planted from the seeds and the enlarged rhizomes of the white lotus which were planted in the plastic containers on April 20 and May 4, 2008, and cultivated under rain shelter condition. Rhizome growth pattern and the flowering characteristics of the white lotus were examined on September 4, 2008. Main rhizomes of the white lotus propagated by the seeds and the enlarged rhizomes were branched by 10% and 15%, respectively. Numbers of nodes in the bloomed and non-bloomed rhizomes of the white lotus were over 14 and below 11, respectively. Flower was not observed in the white lotus when propagated with seeds, however, flowers came out up to 80% by the enlarged rhizomes. First flowers were bloomed from the late July and to the early August, and the number of flowers were 4.0~4.4. The first flower stalks without branching of the main rhizome were emerged in 8.8th node, however, that with branching were 8.0th node. Time to flowering from the emergence of flower stalk on the above-ground parts were required 16 days. White flowers from the lotus were 15.3 cm in height and 28.2 cm in width, their longevity was 3.3 days and the averaged flower fresh weight was 29.2 g. The results conclude that optimum number of nodes on the main rhizomes for blooming the white lotus flowers should be over 8 nodes before the rhizome enlargement.

Effects of Daminozide Spray and Floral Preservatives on Longevity and Ethylene Production of Cut Lily (Lilium longiflorum Thunb.) (수확전(收穫前) Daminozide의 살포(撒布)와 수확후(收穫後) 절화보존제(切花保存劑)의 처리(處理)가 절화백합(切花百合)의 수명(壽命)과 Ethylene발생(發生)에 미치는 영향(影響))

  • This study was conducted to clarify the effects of daminozide (butanedioic acid mono-(2,2 - dimethylhydrazide)) sprayed 2 days be fore harvest and floral preservative solutions on longevity, quality and ethylene production of 'Georgia' cut lily for prolonging vase life and improving quality of cut lily flowers. And also the relation between ethylene production and flower senescence of cut lily was studied. 1. Lilies held in silver nitrate ($AgNO_3$) at 25 and 50 ppm were increased in solution uptake, fresh weight, and flower longevity. The solution of 2.5% sucrose+50 ppm $AgNO_3$+200 ppm aluminum sulfate+10 ppm 6-benzylamino purine prolonged vase life and improved quality of cut lily flowers. 2. Lilies sprayed with 500 ppm daminozide 2 days be fore harvest and then held in the preservative solution (5% sucrose+50 ppm $AgNO_3$+150ppm 8-hydroxyquinoline) after harvest were significantly increased in fresh weight and vase life as compared with non-sprayed (control) flowers. 3. Ethylene production from cut lily was increased by ethephon ((2-chloroethyl) phosphonic acid) treatment. The flowers producing a lot of ethylene, however, were senesced slowly instead of rapid wilting. 4. The preservative solution markedly reduced ethylene production of cut lily but prolonged vase life for only a few days. 5. These results suggest that ethylene be one of the most important factors promoting flower senescence of cut lily, but it be very difficult to prolong vase life remarkably by only inhibition of ethylene production in cut lily.

  • In this study, the subjects are the expression methods and compositions of peony patterns in Chinese textiles. This study represents the peony patterns which are from Tang Dynasty to the Qing Dynasty, the research subjects are the peony patterns in fabric, except the peony patterns which are expressed by gold foil, embroidery and kesi. The objects of this study are 72 pieces of peony patterns. We sketched the configuration details of peony patterns through the Illustrator program. Analyze and classify the configuration accurately. Based on the 72 pieces of peony patterns, expression methods and compositions of the peony pattern are as following, firstly, we classified peony patterns into three categories, based on expression methods, as realistic shape, pattern shape and shape. Among these 72 fabric relics, there most of realistic shape 42 pieces(58.3%), pattern shape 25 pieces(34.7%), and shape 5 pieces(7.0%). Secondly, in the realistic shape peony, the most of pattern has petal accumulate as grape- shaped. This type is found in almost every Dynasty and was used regularly in the eras of Song and Ming Dynasty. In the era of Ming Dynasty, by using petals like the curly mushroom, Yeongji(靈芝), the pattern of symbolizing longevity was habitually used. The U-shaped flower pattern (type E) and the pattern of emphasizing the veins of petals are found only in the remains of the era of Qing Dynasty. Thirdly, in the pattern shaped peony, the most of pattern has some petals which are separated(type C). Fourthly, we classified peony patterns into four categories, based on compositions, as individual branch form, floral branch form, cluster branch form and floral nest form. Among these 72 fabric relics, there most of individual branch form 33 pieces(45.8%), floral branch form 18 pieces(25.0%), cluster branch form 13 pieces(18.1%), floral nest form 8 pieces(11.1%).

  • Anthocorid bugs (Orius spp.) are known as polyphagous predators preying on thrips, aphids, mites, eggs of small insects and whiteflies. This study was conducted to investigate the nym-phal development, survival rate, longevity of Orius sauteri adult and oviposition, when nymphs of western flower thrips (Frankliniella occidentalis) and cotton aphid (Aphis gossypii), and eggs of two-spotted spider mite (Tetranychus uritcae) were fed as diets. Nymphal development of female/male O. sauferi fed with F. occidentalis, A. gossypii and T urticae took 12.2/12.8, 13.0/l3.2, and 17.9/17.8 days at 27$^{\circ}C$, respectively, Survival rates during nymphal development were 96.4, 78.4, 73.8%, longevity of female/male adults were 55.9/51.0, 30.2/30.8, and 25.8/25.1 days, and daily oviposition were 5.6, 4.1, and 1.9 eggs, respectively. Oviposition of O. sauteri fed with F. occidentalis usually began 3-4 days after emergence at 27$^{\circ}C$, and reached at its peak of 7-8 eggs female day 20-40 days after emergence.

  • A Beoseonbongip is a pouch that holds patterns for making Beoseons. This study aimed to identify the aesthetic and symbolic contents of the embroidery patterns by analyzing the kind, combination types, expression and arrangement types of patterns. In total, 140 Beoseonbongip artifacts, which were mostly made in the Joseon Dynasty, were quantitatively and qualitatively analyzed. The results indicated that about 83% of the total had flower patterns. Various kinds of embroidery patterns used for Beoseonbongips were newly identified. About 73% of the total had different kinds of patterns. Pattern combination types were identified by the kinds of patterns, the number of paired patterns, and the traditional painting styles used. The patterns of Beoseonbongips were expressed schematically more than realistically or abstractly. Beoseonbongips with different patterns on the four triangle tips of the front face and Beoseonbongips with the same/similar patterns on two opposite tips of the front face were observed more than the other types. On the back face, the embroidery patterns were symmetrically arranged, showing various division structures. It was inferred that wishes (e.g., marital harmony, fertility, good health and longevity, happiness, and wealth and fame) were expressed through the symbolic patterns embroidered on the Beoseonbongips. In terms of Korean traditional beauty, the union with nature, the harmony of yin and yang, symmetric balance, and neatness were also emphasized as a esthetic characteristics of Beoseonbongips.

  • 'Pattern' is of very unique nature in each and every country around the world, and its aesthetic feeling of 'pattern' has been handed down according to its nationality and cultural development process. That is, 'pattern' is ornament to symbolize each country's aesthetic standard or choice through some shape, reflecting social consciousness or religion philosophy. Mostly based upon literature survey and case study, this survey paper analytically compares oriental botanical pattern with occidental botanical figure, which has been influenced by Buddhism-Confucianism and Christian religion respectively. The results show that some patterns are commonly used in both area, while meaning differently in some cases: lotus (life), pomegranate (wealth and prosperity in orient, resurrection in occident), grape (fecundity in orient, wealth in occident), dangcho (fecundity in orient, victory in occident). And the other patterns look uniquely used either just in orient or only in occident. For instance, oriental area had its own patterns such as peony (meaning wealth and honour), peach (longevity), ume flower (happiness), orchid (fecundity); while occidental area used lily (purity), olive (peace), palm (victory), and so on. Interestingly, the botanical patterns were used as main patterns in orient whereas as minor in occident.
