본 연구는 감마선 조사 시기, 강도 및 조사 후 보존제 처리가 절화장미와 국화의 수명에 미치는 영향을 알기 위하여 시행하였던 바 얻은 결과는 다음과 같았다. 절화장미의 경우 감마선 조사 강도가 0.5 KGy 까지는 절화품질에 미치는 영향이 적다고 할 수 있었으나, 이 보다 강한 조사구에서는 절화장미의 품질이 매우 악화되었으며, 조사 후 설탕용액에 침지한 것은 0.75 KGy 처리구까지 절화의 품질 유지효과가 인정되었다. 조사 후 절화보존제 침지 처리의 효과 실험에서는 2% sucrose, 0.2% silver nitrate, 1.0% Crysal 처리구에서 각각 선도 유지 효과가 어느 정도 인정되었으나, silver nitrate 처리구에서는 절화기부의 갈변부패가 매우 심한 것에서 절화수명의 연장에는 별 효과가 없었음을 알 수 있었다. 절화국화의 경우에는 감마선 조사 강도가 강해질수록 관산가치가 급격히 저하되었으며, 2.0KGy의 강도로 조사한 감마선 처리구에서는 증류수 및 HQS에 침지한 절화를 제외하고 다른 절화 보존제 처리구에서는 절화 수명이 급격히 저하되었다. 절화 보존제의 처리효과 중에 설탕용액의 침지 효과가 제일 우수하였는데, 감마선 무조사구에서 절화가 완전히 시들 때까지도 어느 정도 꽃을 관상 할 수 있을 정도로 절화수명은 유지되었다.

The present study was conducted to determine the effects of electron beam irradiation on the postharvest quality of cut flowers. Cut flowers were irradiated with electron beam at 100, 200, 400, 600, 800, 1,000, and 2,000 Gy with a 10 MeV linear electron beam accelerator to evaluate their irradiation tolerance. Postharvest quality was determined by monitoring fresh weight loss, flower longevity, flower diameter, flowering rate, visual quality of flowers and leaves, and chlorophyll content. Cut flowers showed a radiation-induced damage with increasing the irradiation dose. Flower longevity and fresh weight of cut flowers decreased when the irradiation dose was increased. Flower bud opening was also inhibited in a dose-dependent manner. The effective irradiation doses for 10% reduction of postharvest quality (ED₁₀) values were 144.4, 451.6, and 841.2 Gy in the 'Medusa' lily, 'Montezuma' carnation, and 'Rosina White' eustoma, respectively. Although tolerance of cut flowers to electron beam irradiation vary according to species, cultivars, or maturity stage conditions, it is conceivable that 'Montezuma' carnation and 'Rosina White' eustoma could be tolerated and maintained overall postharvest quality up to 400 Gy, the generic irradiation dose approved by the Animal and Plant Health Inspection Service (APHIS) and the International Plant Protection Convention (IPPC) for postharvest phytosanitary treatments.

When bougainvilleas are subjected to indoor low-light conditions, flower bracts regularly abscise. This study elucidates the effects of plant growth regulators on bract longevity of potted bougainvillea. Potted 'Taipei Red' bougainvillea in four different bract development stages were treated with 1-MCP (1-methylcyclopropene), NAA (1-naphthaleneacetic acid), SNA (sodium salt of naphthaleneacetic acid), IBA (indolebutyric acid), BA (6-benzylaminopurine), $KH_2PO_4$ (potassium dihydrogen phosphate), Put (diamine putrescine), SA (salicylic acid), or STS (silver thiosulfate) and were moved to indoor low-light conditions after treatments. Experimental results indicate that 1-MCP, NAA, SNA, BA, Put, and SA prolonged bract longevity, and this effect increased as bract stage increased. The effect of STS was significant in early bract stages and decreased as bract stages increased. Additionally, 1-MCP, NAA, SNA, BA, Put, SA, and STS treatment significantly reduced endogenous ACC (1-aminocyclopropene-1-carboxylate) content and ACC oxidase activity, suggesting that the inhibition of ethylene production was achieved via physiological metabolism. However, treatment with IBA or $KH_2PO_4$ had no effect on the bract longevity at any stage. In the combined chemical treatments, NAA + STS or NAA + SA were effectively for prolonging bract longevity and contained less protein or chlorophyll degradation, decrease ACC oxidase or ethylene production than the control. In conclusion, we propose that combined chemical treatment significantly prolonged the bract longevity and more effectively than single chemical treatment at any stage.

본 연구목적은 아이리스 'Blue Magic' 절화의 수명연장, 절화 품질 향상 및 개화율을 촉진시키기 위하여 수행되었다. 절화 아이리스의 수명을 연장하기 위해 1-MCP는 250, 500, $750nL{\cdot}L^{-1}$로 처리하였다. 1-MCP 처리는 무처리구에 비해 개화소요일수가 1일 빨라졌으나 절화수명은 무처리구와 처리구간 큰 차이가 나타나지 않았다. 개화율은 대조구의 경우 64.2%에 비해 1-MCP 처리구 에서는 75% 또는 그 이상 이었다. 특히, $250nL{\cdot}L^{-1}$를 12시간 처리한 구에서는 모든 개체가 개화하였다. 화기로부터 에틸렌이 생성되는 것은 절화수명에 있어 가장 중요한 요인으로 간주되고 있다. Gas chromatography(GC)로 에틸렌 생성량을 측정한 결과 절화수명과 방출된 에틸렌 사이에는 직접적인 관련이 없었다. 무처리구와 비교하여 에틸렌 발생은 1-MCP의 농도가 증가할수록 다소 증가하는 것으로 나타났다. 1-MCP와 BA를 병행처리한 경우, 개화율이 촉진될 뿐만 아니라 절화수명도 연장되었다. 그러므로 아이리스 절화 수확 시 1-MCP를 처리하는 것은 미개화율을 억제함으로써 절화품질과 수명을 향상시킬 수 있다.

Patterns abstractly depicting flowing water with Chinese characters such as gong, wan(man), or wang continued endlessly and curved water patterns began appearing on textiles during the Song Dynasty. Though Song curved water patterns encompassed poetic sentiments such as "falling flowers and flowing water," the meaning faded with time, and these patterns were depicted in backgrounds with flowers added to brocade (Geum-sang-cheom-hwa). During the Ming and Qing Dynasties, combinations of diverse patterns, including flowers, butterflies, dragons, and auspicious treasures became fashionable, rather than the gong- and wan-shaped curved water patterns. Likewise, during the Joseon Dynasty, curved water patterns were preferred as background rather than as primary patterns. They were overlaid with flowers and clouds. The overlaid flower patterns included four-season flower patterns (17th-18th centuries), round flower patterns (19th century), and large flower patterns (20th century), which were identical to flower patterns fashionable at the time and arranged at intervals on complex curved water pattern backgrounds. In contrast, simple Ruyi types were more numerous than the four-Ruyi types fashionable at the time with regard to cloud patterns. Added here were Taiji (great ultimate symbol) or crane patterns, thus seeking to depict diverse auspicious Ruyi such as wish fulfillment and longevity.

In this study, it is investigated the types and the compounding method of flower patterns and the uses of flower patterned fabrics in Chosun Dynasty. Research was done through the references of exhumed clothing during 16-17th century. Our ancestors had used the various flower patterns based on Buddhism, Taoism and Confucianism onto the fabrics. The flower patterns on the fabrics were expressed with the other patterns such as treasure patterns, letter patterns or bird patterns. And the flower patterns symbolized the various good meanings such as longevity, integrity and prosperity etc. In the order of the percentage, the types of the flower patterns were shown Lotus(27.31%), Arabesque(26.85%), Japanese apricot(14.81%), Peony(8.79%), Flowering plants(6.94%), Chrysanthemum(6.01%), Pomegranate(2.31%) patterns and so on. Especially the Lotus pattern was shown up most frequently. That of shape was designed as blooming(開花), full bloom(滿開) and the side of flower(側面). By the compounding method, the compound types mixed with the other patterns were used much more than the individual types composed by its own pattern. The flower patterns were used a lot in Jeogori(Jacket) regardless of the ganders and in men's Po(coat) including Cheollik(天翼), Dappo(胡), Jeonbok(戰服), Dahnryoung(團領), etc. Also contrary to these days, the flower patterned fabrics had come out in the shrouds. Judging from these facts, our ancestors wished that the meaning of the immortal life was included in the flower pattern.

The purpose of this study was to examine of the flower patterned fabrics used for the Shrouds during 15~18th century in Chosun Dynasty. The Shrouds at that time could be classified by the garments for the dead(殮襲衣) and the utensils used in religious services(殮襲諸具). And we looked into the types and the compounding methods of the flower pattern used for the utensils used in religious services(殮襲諸具) as well as the Shrouds accounting to the uses. Results of this study are as follows. 1) The flower patterned fabrics weaved as the uses of the garments for the dead(殮襲衣), item by item, were divided into the upper garment, the lower garment and men's Po(coat). 2) Seeing Jeogori, mixed various flower patterned fabrics, among the upper garment, there were focused on the various good meanings such as longevity, integrity and prosperity etc. 3) The flower patterns in men's Po(coat) were used a lot in Jangui and Dahnryoung. Cheollik, Dappo, Jeonbok, etc made of the flower patterned fabrics, were of small number but we can feel an aesthetic sense of men at that time. 4) The flower patterned fabrics weaved the lower garments, were used much more in the skirts than in the trousers, for reasons of the wrapping a dead body. 5) Seeing the flower pattern used the utensils used in religious services(殮襲諸具), the pattern of Lotus and Arabesque, among the types of flower pattern, had a majority.
