Effect of Postharvest Temperature Management on Scent Emission from Cut Flowers of Tulip Cultivars

Tulip (Tulipa gesneriana L.) cultivars exhibit diverse floral scents, the emissions of which are generally influenced by temperature. To fully benefit from these scents and add value to cut tulips, it is necessary evaluate scent emission response This study investigated daily changes 82 volatiles, including main compounds, at different temperatures (13, 18, 23°C), in tulips eight tulip with scents. At 23 18°C, total each cultivar increased flower opening subsequently decreased visible senescence. Floral senescence progressed more rapidly 23°C, decrease occurred most 23°C. Scent 18°C tended be lower than The vase life was prolonged 13°C owing slow senescence; however, remained low after opening. These results indicate that improving both under constant temperature conditions difficult. It observed composition changed before opening, In contrast, had little effect on composition. Cut stored a (10 or 15°C) over four half days then transferred room (20°C) longer maintained temperature, due delayed addition, were temperatures, but upon transfer Therefore, storage may lead findings imply low-temperature sale contributes rich sale. reported here demonstrate improvement appropriate management.
