Effect of preharvest conditions on cut-flower quality

open access: yesFrontiers in Plant Science, 2023
The cut flower industry has a global reach as flowers are often produced in countries around the equator and transported by plane or ship (reefer) mostly to the global north. Vase-life issues are often regarded as linked to only postharvest conditions while cultivation factors are just as important. Here, we review the main causes for quality reduction
