A DYNAMIC COMPUTER MODEL PREDICTING THE LONGEVITY OF EIGHT CUT FLOWER SPECIES
The length of flower vase life (longevity), at any point in time after harvest, may depend on the properties of the flowering stem at harvest, which are influenced by growing conditions, and by the treatment after harvest. A model was formulated that predicted the postharvest longevity, as a function of the conditions after harvest, such as ambient temperatures, humidity, ethylene and pretreatment with ethylene antagonists, the presence of fungus spores in the air and of bacteria in the water, transport in water or dry, recutting of the stems, and the inclusion of a flower preservative in the vase solution. The model was made dynamic by integration of the partial derivatives with respect to time, incorporating all changes through time of any of the aforementioned variables. Although the model is inherently weak in some areas, because of lack of experimental data, it serves as a starting point for further experimental work.
