Vase Life and Quality of Cut Flower by Wet Solution according to Shipping Period and Temperature in Dendranthema grandiflorum ‘Jinba’

This study was conducted to examine the effects of wet storage solution, transport period and temperature on vase life and quality of cut flowers in standard chrysanthemum ‘Jinba’. Immediately after transport, the fresh weight and flower diameter of cut flowers did not show a difference according to wet storage solutions regardless of the transport period, but as the transport period increased, the fresh weight and flower diameter increased. The flower bud stage at harvest was maintained due to the small changes in flower diameter, and the freshness of leaves was better when transported at 5℃ than at 25℃. When transported at 25℃, the longer the transport period, the lower the quality of cut flowers as some petals opened up and showed early flowering after transport. In preservative solutions, quality of cut flowers transported at 25℃ was lower than that at 5℃ due to fresh weight and diameter according to the longer transport period. The vase life of cut flowers was 1.0 day, 0.8 day, and 7.3 days longer when transported for 3, 5, and 7 days respectively at 5℃ than at 25℃. The quality of cut flowers was better due to increase in fresh weight and flower diameter, as well as vase life in wet storage solutions of ClO₂ and Chrysal OVB than in tap water, regardless of transport period and temperature. There was no difference in fresh weight and vase life between ClO₂ and Chrysal OVB, but flower diameter was greater in ClO₂ than in Chrysal OVB. Therefore, for long-term transport of cut standard chrysanthemum ‘Jinba’, wet storage transport in ClO₂ at 5℃ was found effective in maintaining the quality and vase life of cut flowers.
