Optimizing Postharvest Life of Cut Zinnias
Each year a large number of new cultivars and species are made available from plant breeders, propagators, and suppliers. Specific postharvest information must be obtained for these new species as they are made available to the market. Zinnia, although grown for many years, continues to be popular with cut flower buyers and breeders. Two cultivars, Benary’s Giant Scarlet (Photo 1) and Sun Gold (Photo 2) were tested to determine the optimum handling procedures to extend postharvest life. Prior trials have shown that zinnia cultivars may respond differently to postharvest handling techniques than many other fresh cut flowers.
