Outline of Final Research Achievements

CO2 treatments at 20% for 12 h prolonged the vase life of cut carnations, while those for 48 h induced physiological disorder of florets such as browning. Precooling at 5 ℃ and 50% CO2 treatment for 12 h suppressed the ethylene production and respiration rate, and thus prolonged the vase life. RNA seq indicated that expression of genes for reduction‐oxidation (Redox) were influenced by the CA treatment. These results suggest that short-term CA treatments could reduce ethylene production and respiration rate, and change Redox related genes, and result in improving quality of flowers. For practical use, it is necessary to set optimum conditions for each species or cultivar.
