Standard carnations are widely used in flower design as a mass flower, but there is a limit to the use in that it can not be used in various colors in addition to its own color. The purpose of this study was to investigate how does artificial dyes affect vase life, using standard carnations, and to improve utilization of dyeing carnations in floral design. Using standard carnation 'White Liberty', dyeing experiment was performed according to four kinds of chemicals for each of six dyes. Six different dyes from Koch(Robert Koch industries Inc., USA) as follows light blue(2386), lime green(2315), christmas red(2506), lavender(2200), orange fire(2268) and black(2012) have been used and four different chemicals as follows distilled water, 4% ethanol, 3% sucrose and 100mg·L^-1 citric acid have been used with the cut Dianthus caryophyllus 'White Liberty'. As a result, six different dyes showed fast and excellent dyeing with 3% sucrose and 100mg·L^-1 citric acid treatment. But vase life in other dyes except black and lavender tended to be similar to control(7 days).

This study was conducted to investigate growth and flowering of hydroponically-grown carnation as affected by substrate and planting date, Three substrates, coir, perlite, and coir＋perlite(1：1. v/v), and two planting dates. May 1 and September 1 were used. Plant height and stem diameter at harvesting time of cut flowers were greater for the September 1 planting than for the May 1 planting. The plants planted on May 1 produced flowers with weak stems and short stem lengths. In addition, flower weight and blossom width were gloater for the September 1 planting than for the Mar 1 planting. The planting date had no significant effect on the number of petals, The carnation planted on May 1 flowered 50 days earlier compared to those Planted on September 1. Plant height and number of petals were the greatest in the plot of coir substrate. The results indicated that for commercial production of cut carnations in a hydroponic system, planting on September 1 is better than May 1. In addition. the results confirm that coir is the superior substrate for the production of cut carnations in a hydroponic system compared to either Perlite or coir＋perlite mixture.

A new spray carnation 'Lepus' was released by the National Institute of Horticultural & Herbal Science in 2004. This hybrid was crossed between 'Diamond' and '99257-7 Line' in 2000. The 269 seedling plants were, planted and cultivated in green house. After investigation of the characteristics for four years (from 2001 to 2004), it was finally selected in 2004. 'Lepus' white color with red peak edge is spray type and strong flower stalks. Also, it has medium fragrance, many flowers, and attractive flower arrangement. In particular, flowering was 10 days early and flower stalk was 13cm longer than 'Diamond' (control). In addition, it has medium resistance of Fusarium and the vase life was similar to 'Diamond'.

This study was conducted to determine the optimum hydroponic system and nutrient solution for promoting the growth and flowering of hydroponically grown carnation. DFT (deep flow technique) and NFT (nutrient film technique) systems were employed and four kinds of nutrient solution, which are Cooper solution, Yamasaki solution, balanced nutrient solution by Japanese Horticultural Experiment Station and PTG solution in the Netherlands were used and compared. pH was lowest in the PTG solution compared to the other nutrient solutions used. Plant height was highest in the DFT system in the plot of PTG solution as of 53.0 cm at 88 days after transplanting, while lowest in NFT system with Cooper solution. Stem diameter was more thickened in NFT system with PTG solution as of 7.2 mm at 88 days after transplanting. Days to flowering was shortened to 122.3 days in NFT system when PTG solution was used. This results suggested a combination of NFT system with PTG solution as optimum hydroponic system and nutrient solution for cut carnation production. Further trials as to the management of nutrient solution by glowing stages should be followed.

A new spray carnation cultivar 'Lyra' was released by the National Institute of Horticultural and Herbal Science in 2003. A cross was made between spray cultivar 'Ballantyne' and red spray cultivar 'Chateau' in 1999. After investigation of the characteristics during four years (from 2000 to 2003), the cultivar 'Lyra' was finally selected in 2003. 'Lyra' is a spray cultivar with bright pink color for a cut flower. The main characteristics are early flowering, multi branching, fragrance and long flower stalk. Also, it has medium resistance to Fusarium wilt and 7 days vase life. To avoid calyx splitting caused by high temperature, it is recommended that this cultivar be grown over $8^{\circ}C$ at night and under $25^{\circ}C$ at day time during a flower bud differentiation period and applied with additional nitrate fertilization ($30.0kg{\cdot}10^{-1}$).

Carnation is considered to be one of the top three cutting flowers in the world, which is a main crop with 21 billion annual volume of manufacture. The four carnation items such as cuttings, seed, plant and unrooted cuttings are imported and exported. Viruses can be easily transmitted during vegetative propagation of carnation. Carnation necrotic fleck virus (CNFV) and Carnation ringspot virus (CRSV) are designated as Korea plant quarantine viruses and inspected. This study was aimed to develop specific primer sets for easy and rapid detection of CNFV and CRSV. Two RT-PCR primer sets were efficiently amplified 288 and 447 bp fragments for CNFV and 503 549 bp fragments for CRSV. Furthermore, developed nested primer sets make possible to high sensitive detection and verification. CNFV nested PCR primer sets all produced band of 147 bp and CRSV nested PCR primer sets did bands of 395 and 347 bp. In addition, plasmid inserted 6 sequences in amplicon were used as a positive control to improve inspection confidence. The successful application of PCR module newly developed in this study will be highly useful for detect of CNFV and CRSV for quarantine inspections.

New standard carnation cultivar "Jasujung" was bred from the cross of red standard cultivar "Francesco" and purple standard cultivar "Saturn" at the National Institute of Horticultural & Herbal Science. It was crossed in 1996 and finally selected in 2000 after investigation of the characteristics for 4 years from 1997 to 2000. "Jasujung", purple standard cultivar for cut flower, has good fragrance and long stem. Especially, it is strong resistance against Fusarium wilt. This cultivar is recommended to grow over $8^{\circ}C$ at night and under $25^{\circ}C$ at days.

This study was conducted to find out the cause of discoloration after pressing yellow-colored flowers. Plant materials used were Lilium Asiatic Hybrids, Oncidium spp., Rosa hybrida, $Tulipa{\times}gesneriana$, Antirrhinum majus, Dianthus caryophyllus, Freesia hybrida, Zantedeschia elliottiana, Gerbera jamesonii, Helianthus annuus, and Ranunculus asiaticus. Thickness, ratio of length to width, and water content of petals did not considerably affect discoloration of pressed flowers. Expression of yellow color in petals was caused by carotenoids in Lilium Asiatic Hybrids, Oncidium spp., Rosa hybrida and $Tulipa{\times}gesneriana$, by flavonoids in Antirrhinum majus, Dianthus caryophyllus, Freesia hybrida and Zantedeschia elliottiana, and by coexistence of carotenoids and flavonoids in Gerbera jamesonii, Helianthus annuus and Ranunculus asiaticus. Carotenoids that expressed yellow color in petals affected significantly on discoloration in pressed flowers containing carotenoids alone or both carotenoids and flavonoids. However, discoloration was hardly ever found in yellow-colored species as affected by flavonoids. Dark treatment was effective for almost perfect preservation in color of pressed flowers, while light treatment resulted in severe discoloration.
