The vase life of carnation flowers has been generally determined by observing senescence profiles, i.e., in-rolling
of petal margin and wilting of whole petals as well as ethylene production. In the present study, we tried to determine the vase life of
spray type carnation flowers by observing the number of open flowers, i.e., the percentage of open flowers to the total number of initial
flower buds. The vase life determined by this method was similar to that determined by the former method, and was useful to
evaluate the action of preservatives on carnation flowers.
