수출용 장미의 여름철 재배환경특성과 절화수명 관계 Correlation between Vase Life of Cut Roses for Export and Cultivation Environments in Summer
pp.312-318
Domestic cut roses tend to be poor in quality especially during summer. This seasonal drop in quality of cut flowers has caused serious export disruption such as inadequate volume or price decline. We investigated the relationship between environmental factors and vase life (VL) of cut roses. Six cut rose varieties, ‘Antique Curl’, ‘Beast’, ‘Iguana’, ‘Legato’, ‘Pink Heart’, and ‘Red Pocket’, were investigated from three commercial farm greenhouses (Farms A, B, a nd C ). The VL of cut flowers ranged f rom 5.8 to 18.2 days depending on the variety. Considering 16 days as the minimum VL required for exportation during the summer season, only two varieties ‘Antique Curl’ and ‘Beast’ would qualify for exportation. VL was significantly negatively correlated to only relative humidity (RH) (r = - 0.69*) among various environmental factors and only to peduncle length (r = - 0.60*) among plant morphological items. Thus, controlling RH is key to improve the vase life of cut roses during the summer production for export.
