The vase life of carnation flowers was considered to have terminated when petals showed in-rolling or
necrosis, and that of Delphinium flowers, when the sepals of the last floret abscissed. The vase life of
florets that opened on the day of harvest was regarded as the period from harvest to the time when its
sepals abscissed. For sweet peas, the vase life of the spikes was regarded as the period from harvest to the time when the last floret wilted. The vase life of florets which opened before the day of harvest,
opened on the day of harvest and unopened at harvest were also determined. The vase life of florets was
considered to have terminated when the petals lost their turgor.
