Because of the complexity of the flower design of roll forming process, in which the flat strip is progressively deformed by successive sets of profiled rolls, a computer-aided design system for the flower design has been developed. It is programmed in AutoLISP and DCL(Dialogue Control Language) of AutoCAD. It has been found that the system is helpful in saving the time and effort required to design the flower of the product to be roll-formed.

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.

The purpose of this study is to explore ways in which the flower design industry can utilize podcasts that are rapidly growing in recent years. I selected foreign flower podcasts that are ranked on the global podcast chart, and examined the genre, content, components, show hosts and etc. By analyzing the characteristics of the podcast, the type of communication between the host and the audience, the audience interaction, the industry connection, and the media expansion strategy, I tried to derive the possibility of the flower podcast in Korea. As a result of analyzing foreign flower podcasts, podcasters built listener communities based on their rich experience and knowledge through podcasts and used them for education and marketing. They acted as leaders in the industry or led public opinion such as the sustainable flower industry. Podcast shows were repurposed as various content and used to spread flower design culture. In Korea, flower podcasts can be the basis for the formation of a community related to the flower design industry. Flower design experts can use podcasts as a source asset for various content. Listeners within the industry can get hands-on knowledge about the business from flower podcasts. The popular flower podcast will contribute to the vitalization of flower design culture and industry. Flower podcasts can be a starting point to actively cope with the era of personal media.

Chrysanthemum indicum is widely used to treat immune-related and infectious disorders in East Asia. C. indicum flower oil contains 1,8-cineole, germacrene D, camphor, ${\alpha}$-cadinol, camphene, pinocarvone, ${\beta}$-caryophyllene, 3-cyclohexen- 1-ol, and ${\gamma}$-curcumene. We evaluated the safety of C. indicum flower oil by conducting acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation tests. Mortality, clinical signs and gross findings of mice were measured for 15 days after the oral single gavage administration of C. indicum flower oil. There were no mortality and clinical signs of toxicity at 2,000 mg/kg body weight/day of C. indicum flower oil throughout the 15 day period. Micronucleated erythrocyte cell counts for all treated groups were not significantly different between test and control groups. Levels of 15.63~500 ${\mu}g$ C. indicum flower oil/plate did not induce mutagenicity in S. Typhimurium and E. coli, with or without the introduction of a metabolic activation system. These results indicate that ingesting C. indicum flower oil produces no acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation.

This study examined the effects of different day/night temperature regimes or silver ion on growth and flowering of passion fruit 'Tai-nung No.1'. Low temperature treatment ($20/15^{\circ}C$) caused passion fruit cultivar 'Tai-nung No.1' to fail to flower. Flowering induction occurred within a temperature range of $20-30^{\circ}C$, with no significant difference in the days to first flower bud and the total number of flower buds between plants grown at $30/25^{\circ}C$ and $25/20^{\circ}C$. However, plants grown at $30/25^{\circ}C$ exhibited their first flower buds set on the higher nodes and had higher abortion rates of flower buds than those at $25/20^{\circ}C$. Plants grown at $30/25^{\circ}C$ had the most rapid growth and the shortest plastochron. We also evaluated the effect of the ethylene response inhibitors silver nitrate ($AgNO_3$) and silver thiosulfate (STS) on growth and flowering of potted passion fruit 'Tai-nung No.1', when they were exposed to low temperature conditions ($20/15^{\circ}C$) following chemical treatments ($AgNO_3$ or STS, at 0.5 or 1.0 mM). $AgNO_3$ and STS treatments induced flower formation and initial flower bud formation within approximately two weeks at $20/15^{\circ}C$ whereas non-treated control plants exhibited no flower formation. ACC content and activity of ACC oxidase in the leaves of passion fruit 'Tai-nung No.1'exposed to low temperature conditions ($20/15^{\circ}C$) were significantly inhibited by the ethylene inhibitor treatments. These results indicate that ethylene, which is produced under low temperature conditions, plays an important role in inhibiting flower formation in passion fruit.

The genetic makeup could be the most important among many factors affecting yield and quality of tobacco(Nicotiana tabacum L.). The mammoth gene found in N. tabacum is associated with greater leaf number and poor leaf quality. This study was carried out to obtain the basic information about the inheritance of mammoth gene and white flower color. Two flue-cured breeding lines, KF 9373-2 and KF 8832-85, F$_1$, F$_2$, two parents backcrossed with F$_1$, and F$_3$ lines derived from cross of above two lines were investigated for flowering type(mammoth gene) and flower color. All plants of F$_1$ population revealed normal flowering type and pink flower color. The progeny of F$_2$ generation was segregated into the phenotypic ratio of 9 : 3 : 3 : 1 with normal flowering type and pink flower color, normal and white, non flowering type(NF) and pink, and NF and white, respectively. Among the progenies of back-crossing populations, the flowering type showed a segregation ratio of 1 : 1 as normal and NF in BP$_1$ and flower color did also 1 : 1 as pink and white in BP$_2$. All lines have the mammoth gene in F$_3$. that were selected in F$_2$ progeny as non flowering. But 9 lines among 14 were segregated with 3 : 1 as pink and white flower in F$_3$. which were selected in F$_2$ as pink flower color. These results indicated that the characters of mammoth gene and white flower were controlled by a pair of recessive genes, respectively.

The purpose of this study was to find new way for vitality of flower shop. The subjects for this research were composed of 58 male and 155 female. In survey of satisfaction of flower shop's product price, 'satisfied' responses in male and female respondents were 8.62 and 14.21%, respectively. Results of survey of consumer's awareness on packaging of flower shop's products have shown that the 'satisfied' responses in male and female respondents were 6.88 and 12.91%, respectively. In question of the satisfaction of flower products as a gift, the 'satisfied' responses in male and female respondents were 8.61% and 1.95%, respectively. In question of the attitude of seller, the 'satisfied' responses in male and female respondents were 6.88% and 6.46%, respectively. In survey of the mind of consumer's repurchase, male and female respondents were satisfied 5.16% and 9.05%, respectively. Our results have shown that consumer's satisfaction in most questions was of low level. Therefore, we propose that these results are associated with the needs of active efforts of flower shop's manager.

This study was conducted to evaluate the influence of fruit setting order by flower cluster on the fruit weight and the soluble solids content for the strawberry of 'Seolhyang' cultivar. The first flower cluster had higher fruit number, fruit weight, soluble solids content and ratio of large fruit compared to the second and third flower cluster. The fruit set on the upper position fruit in the same flower cluster had higher fruit weight and the soluble solids compared to the fruit set on the lower position fruit in the flower cluster. The fruit weight was highly positive correlated with the soluble solids content. The result indicated that the number of fruit set for marketable yield seemed to be 9-10 per the first flower cluster, 6 per the second flower cluster, 4 per the third flower cluster and 3 per the fourth flower cluster in 'Seolhyang' cultivar.
