In many countries, carnation is one of the most popular cut
flowers and of highest economic importance in the floriculture
industry. Cut flowers of carnation are used in two forms or
categories, i.e., the standard type in which carnations have one
flower on a stem and the spray type in which carnations have
multiple flowers on a stem. In recent years, spray type carnation
flowers have become popular because they can be grown with
less labour and meet modern consumer’s demand. Carnation
cultivars differ in the length ofthe vase life of cut flowers(Nukui
et al., 2004), which is one of the characteristics determining the
commercial value of the ornamental flowers. Thus, it is of
economical importance to know the vase life of cut carnation
flowers of different cultivars
