Every year, postharvest trials are performed on cut flower trials grown at our Horticulture Field Labs. The typical layout for the trials is to harvest field-grown flowers at the optimum stage of flower development, immediately place into tap water upon harvest, then subsequently sort them and place them into the following treatments:
- Hydrator only
- Holding preservative only
- Hydrator followed by holding preservative
- Deionized water only
After treatment, stems are placed at room temperature under approximately 200 ftc of light for 12 hrs/day, and vase life is recorded for each stem as it is terminated.
The exact experimental methods for each year are detailed in that year’s page.
