Sugar and Acidity in Preservative Solutions for Field-Grown Cut Flowers
introduction: As more and more growers are expanding their businesses by growing field-grown cut flowers, it is important to understand that all handling, from harvesting to marketing, will significantly affect the quality and the longevity of the flowers. Therefore, growing those beautiful field-grown flowers is only part of what it takes to have a successful cut flower business.
Once harvested from the plant, flowers undergo physiological changes that often lead to an early senescence. Steps to delay the process rely on consideration of many aspects of handling. Factors such as the stage and time of day of harvesting, bunching, sleeving, boxing (if necessary), temperature treatment, and the holding solution will all influence the quality and longevity of the flowers. In this article, I will discuss how sugars affect the postharvest quality of cut flowers and what a grower can do to optimize their postharvest performance.
