Effects of Flowering Stage on Cut Flower Quality in Spray Chrysanthemum ‘Lemon ND’

This study was conducted to examine the effects of flowering stage after simulated shipping during 48hr at 20℃ on quality and senescence of cut flower in spray chrysanthemum ‘Lemon ND’(Dendranthema grandiflorum ‘Lemon ND’). Flower diameter of cut flower harvested in first or second stage was 10mm smaller than that harvested in fifth stage. Fresh weight of cut flower was light in fast flowering stage, and that of first stage was lighter by 13g than that of fifth stage at 2 days in holding solution. Cut flower of third stage absorbed the most solution, and Total solution uptake of flower in earlier and later stage than third stage decreased. The days to 50% senescence rate in fifth stage was the shortest, and vase life was 12.4 days. In cut flowers of earlier stage, days to 50% senescence rate and vase life were prolonged.
