Like all other living organisms, flowering plants undergo respiratory processes that generate heat. Retention of this heat of metabolism has been linked to the rapid aging of cut flowers. Although ambient heat is easily eliminated in most open-air locations, storing flowers in sealed boxes hastens the rate at which they age. This decrease in longevity is due to the undissipated thermal energy retained around the flowers. As a result, the flowers will respire at a faster rate, generate more heat and hence age quicker.
To avoid storing flowers in a hot and harmful environment, florists should consider cooling systems for flower storage. Floral chillers can help keep the ambient temperatures in floral preservation units within acceptable ranges thus ensuring flowers remain fresh for longer. To ensure cut flowers last longer, high levels of humidity are required. Ambient air saturation should be around 90% – 95%. Also, cut flowers will require adequate rehydration once they’ve been harvested from their source plants. To achieve optimal hydration levels, flower stems should be immersed in clean water free of contaminants which may impair the free flow of water through them. When properly hydrated, cut flowers will retain their freshness for longer periods.
It is vital to recognize that the presence of air bubbles or bacteria in cut plant stems may stagnate water transport through their lumen and this problem should be addressed in the post-harvest care of cut flowers.Deciding the best temperature to store cut flowers depends on the species intended for preservation. For most flower types, optimal storage temperatures range between 0°C-3°C while cold-sensitive blossoms and tropical flowers should be maintained at temperatures above 10°C. Ideally, the optimal atmospheric temperature for cut flowers should be closely regulated. Thermal conditions within the storage facility should be monitored to closely mirror the temperature within the cut flower boxes. In most instances, temperatures should not exceed 4°C
In order to efficiently monitor the storage temperature of cut flowers, temperature data loggers are the right choice. BlueTag TH20 is an intelligent Bluetooth HACCP temperature and humidity data logger based on Bluetooth communication technology.
