Roses are the most popular floriculture crops in the world, and Japan is a major exporter of cut roses. The main varieties exported to Japan is a type of spray cut rose ‘Lovely Lydia (Rosa hybrida ''Lovely Lydia'')’. Thus, this study was conducted to investigate the quality of cut flower ''Lovely Lydia’ according to seasonal greenhouse environment and the analysis of conveyance environment during shipping export to Japan. As a result, the temperature difference between day and night was managed within 10℃ in spring. Relative humidities of the three greenhouses were over a maximum of 90%. In the case of G2, it was found that the solar radiation difference between day and night in April and May was not in a regular deviation, while G1 and G3 were investigated to have a similar pattern. It was shown that each greenhouse had provided pH, EC of the nutrient solution in an appropriate range. The accumulated integrated solar radiation irradiance of G2 was unstable compared to G1 and G3. So it has been determined to affect the vase life. The results of this work showed that vase life was shorted by G2 compared to G1 and G3. Also, the summer cultivation environment analysis results, the lowest temperature of the G1 and G3 in night time was 9.2℃ and 10.5℃. There were a difference of almost 20 or more in day time and night time except G2. In addition, G1 and G2 was investigated to irregular patterns of the relative humidity of day time and night time in the end of August. Integrated solar radiation of G2 was maintained a constant light intensity compared to other greenhouses in summer. and G1 was higher than G2 more than about 700μmolm?-2?d-1 in summer compared to spring. It was considered to the vase life was affected to temperature and integrated solar radiation in Greenhouse. Analysis of the export and transportation when temperature and humidity environment depending on the season, before Shipping from Korea to Japan spring and summer, the korea export company in floriculture, the flowers send to low temperatures during shipping to Japan, and the next procedures was quarantine at ambient temperature in Japan. Also after quarantining in Japan, Flowers sent from Korea were transferred to Japanese import companies in floriculture. After the flowers were sent to other locations in Japan wholesale market. As a result of the analysis of springtime vase life of roses in Japan after export process, the vase life was 13 days; and the vase life of roses that were cut on the same day in Korea and applied with a mock export process was 16 days. It was concluded that this was due to physical impacts, such as boxes being crushed, cut flowers colliding one another or scratched by thorns, during transport and shipment in import process, which led to the flowers’ relatively shorter vase life. As a result of the analysis of conveyance environment during shipping export to Japan in the summertime, it was confirmed that the same route as the springtime was used in the export process; however, the environment was higher in temperature and humidity comparing with spring, making it more unstable. According to the study made in Japan, the vase life of summer roses was 10 days. Combining the above results, it is needed to take seasonal changes into consideration and apply cultivation environment fitting each season in order to ensure the production of consistently high-quality roses per season and farm, and through improved environment of shipment during export process, it is needed to standardize the maintenance period to guarantee optimal quality of flowers.
