The cut flowers are living organs, with intense metabolic activity, subjected to a rapid aging process compared to the undetached flowers from the mother plant. Improving the life of cut flowers is one of the most important factors for customer satisfaction. The effect of silver thiosulphate (STS) and commercial mixtures was studied in carnation cut flowers and kept in randomized vases according to experimental factors. Three commercial mixtures were used (Chrysal, Flower Food, Fleur̛ Rose) and for thiosulphate four levels (0 or control, 0.03, 0.06 and 0.9 mM). The interaction of the two factors studied was insignificant for most traits, including wilting percentage and vase lifespan, which may involve the application of both substances alone is sufficient to improve post-harvest quality and is not necessary to use simultaneously in the preservative solution. The results also showed that following the interaction of the two factors, treatment with 0.06 mM silver thiosulphate can be applied to improve the post-harvest quality of blossom cut flowers and commercial chemical mixtures can be successfully replaced.
