Gamma irradiation and its convergence with nano-silver particles and sodium dichloroisocyanurate (NaDCC) were investigated to inhibit germination and mycelial growth of Botrytis elliptica, the pathogen of lily leaf blight. In addition, the same treatments were studied on the process of disease development with detached leaf of lily cv. Siberia. Spray inoculation, which is closer to natural infection than wound inoculation, can be a way to investigate infection ability of the treated pathogen. The irradiating dose required to reduce the population by 90%, $D_{10}$, was 526 Gy irradiating with 0-2000 Gy gamma ray on the conidial suspension as well as the growing mycelia. Even at 2000 Gy, the mycelium was not killed but just delayed its growth at 1-2 days behind. Convergent treatment with 40 mg/l of NaDCC just before 200 Gy gamma irradiation was the best way to decrease the conidial germination about 1/1000 times. The control values of gamma irradiation were 23% and 19.5% at wound inoculation and spray inoculation, respectively. On wound-inoculation, the control value of NaDCC only was 89%, and that of NaDCC convergent with 200 Gy gamma irradiation was 32%. On sprayinoculation, the highest control value was NaDCC at 50%, and that of NaDCC convergent with gamma irradiation was 24%.

Growth and tuber development of ‘Black Magic’calla lily as affected by the rain shelter with 50％ shading and the tuber size were investigated. Tubers of five grades in size were cultivated in the rain shelter or in the open field (control). Days to emergence of shoots in the rain shelter was accelerated by 4.2 days as compared to the open field. Emergence ratio was higher as the tuber was larger, tubers grown in the rain shelter showed the significance in the growth characteristics as compared to the control. There were no significant differences in the number of flowers per tuber between the rain shelter and the open field. Flower quality was 12.2 cm longer than that in the open field. flowering characteristics was improved with the increasing tuber size. Low infection of soft rot disease of 3∼22％ was found in the rain shelter as compared to the that of 19∼83％ in the open field. Thus tubers produced under the rain shelter showed improved quality, Even if the small tubers with diameters of 0.5∼1.0 cm were cultivated in the rain shelter, the weight and diameters of tuber harvested after approximately 7 months were 50.2 g and 5.7 cm, respectively.

This study was conducted to improve the consumption of floriculture plants by researching preferences of consumers for the main types of cut flowers. We analyzed the results of surveys, carried out by a company, that were largely about roses, chrysanthemums, and lilies. After departmentalizing consumers into groups and analyzing the results through conjoint and cluster analysis, we found that consumers showed a higher rate of use based on price and vase life than on flower color and flower shape in roses. The groups of rose consumers preferred a price of 1000 won, spray type flower shape, vase life of 7-8 days, and red flower color. In chrysanthemums, consumers showed higher rate of use for flower color than for vase life, flower shape, and price. The groups of chrysanthemum consumers preferred a price of 1000 won, standard flower shape, 16-20 days vase life, and yellow flower color. In lilies, consumers showed higher use rate for flower shape than vase life, price, and flower color. Lily consumers preferred a price of 2000 won, large flower shape, 4-7 days vase life, and yellow flower color. Thus, the major cut flowers (rose, chrysanthemum, and lily) all showed highest use rates in for vase life. These results highlight the importance of understanding the characteristics of consumer interests. They also emphasize that we should plan and create market-oriented and consumer-oriented products to improve the consumption of floriculture plants.

An Asiatic lily cultivar 'Asian Flame' was bred in 2007 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA) of Korea. The crossing was conducted between female parent A94-34 ('Montreux' ${\times}$ 'Anabelle') and male parent 'Fire' by stigmatic pollination at Suwon in 1996. First selection was done and tentatively named as A98-98 in 1998. After in vitro multiplication and bulb production of A98-98 line, growth and flowering characteristic tests has been conducted from 2005 to 2007. The evaluation of characteristics and preference were surveyed at a lily flower show of NIHHS in 2007 in Taean. The new cultivar 'Asian Flame' flowers in middle of June and grows to an average of 122.7 cm in height. Flowers bloom upward-facing, red (RHS 45B) petals. Year-round flowering is possible by storage of the bulb under $-1.5^{\circ}C$ conditions. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales of large bulb to prevent leaf scorch.

An Asiatic lily cultivar 'Yeri' was developed in 2005 at National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), Korea. The cross was made in 1993 between Asiatic lily 'Geneve', a light pink colored cultivar, and 'Montreux', deep purple colored cultivar. The first selection was done and was tentatively named as 'A95-68' in 1995. After in vitro multiplication and bulbing production, growth and flowering characteristic tests were conducted from 1996 to 2003. The evaluation of characteristics was performed and named as 'Wongyo C1-19' in 2005 that was registered as 'Yeri' to the registration office of Korea Seed & Variety Service. 'Yeri' flowered at the first of July and grew average 34.6 cm stem in length. Flowers bloomed facing upward, unspotted in petals and deep purple (RHS, RP58A). The size of flower was 13.3 cm. Mean petal length and width was 7.7 cm and 2.7 cm, respectively. Leaves were 5.1 cm long and 0.5 cm wide, respectively. The weight and size of bulb were 9.6 g and 11.7 cm, respectively. Year-round flowering can be done by storing the bulb under $-1.5^{\circ}C$ conditions. For forced cultivation, it was necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. It was needed to control Botrytis disease in wet season.

This research was conducted to figure out the effect of 1-methylcyclopropene, one of inhibitors of ethylene on the vase life of cut alstroemeria 'Alpine', snapdragon 'Fuji no Yuki', dahlia 'Toast, and lily 'Georgia'. Four kinds of cut flowers were treated with 250, 500, and 750 ppb of 1-MCP respectively for 12 hours. In case of cut alstroemeria, no significant difference was found between the untreated control and the treated ones in the days to flowering. The vase life in the treated ones, however, was extended for over two days, and the treated one with 250 ppb had the longest record with 17.1 days. In every treated ones of cut snapdragon, the remaining florets was more than that of the untreated control. The vase life showed, however, no difference. With the 1-MCP treatment, the vase life of cut dahlia was longer about two days than that of the untreated control. However, water uptake showed the opposite result. The vase life of cut lily showed no significant differences in all treatments. In case of water absorption, the treated one with 750 ppb uptaken more water by 3 ml.
