Extending the Vase Life of Cut Flowers: Pre-Treatments and Preservatives Studied

ScienceDaily (July 1, 2011) — Each year, a wide variety of new cut flower cultivars and species are evaluated in trials administered by North Carolina State University and the Association of Specialty Cut Flower Growers. The research, conducted at about 50 locations in the United States and Canada, provides valuable production and marketing information.

The researchers concluded that, for the majority of cultivars in the study, either all treatments produced a similar vase life or treatment with a holding preservative produced the longest vase life. They cautioned, however, that "a universal recommendation for use of a holding preservative cannot be made as it reduced the vase life of 14 cultivars." The study results also indicated that hydrator preservatives are "not advantageous" in extending the vase life of most of the cut flowers studied.
