“…Research on the potted plant quality of kalanchoe before transport has primarily focused on certain aspect of the cultivation environment, such as light, air temperature, relative humidity, CO 2 , fertilizer, and growth retardant treatments (Leonard and Nell, 1998;Kim et al, 2014;Coelho et al, 2018;Cho et al, 2020;Park et al, 2021). It has been found that the shelf life and quality of potted plants are improved when 1-methylcyclopropene (1-MCP), 1-hexylcyclopropene (1-HCP), and 1-octylcyclopropene (1-OCP) are used as ethylene inhibitors before the exporting of kalanchoe to Japan, as kalanchoe is an ethylene-sensitive plant (Kebenei et al, 2003;Park et al, 2011).…”

In this study, we investigated the effects of the substrate water content on potted kalanchoe (Kalanchoe blossfeldiana) in an export distribution simulation. Potted kalanchoe plants were treated either with the optimum substrate water content (OSW, 50 -60%) or a low substrate water content (LSW, ≤ 20%) and the postharvest quality and shelf life were assessed at farm or wholesale, export, auction, and consumer stages. The shelf life of the LSW flowers was shorter than that of the OSW flowers by 36%. The primary reason for the short shelf life after the LSW treatment was an increase in leaf chlorosis. The plant height was shorter with the LSW treatment at all stages, while the plant width was longer before the export stage. The fresh and dry weights of the root with the LSW treatment were lower at all stages. The chlorophyll content and the Fv/Fm of the leaves were lower during the auction stage for the LSW treatment. The Fv/Fm of the OSW treatment and LSW treatment were 0.79 and 0.77, respectively, during the auction stage. The change in the size of the stomatal pores and complexes was higher for the LSW treatment at all stages, but this difference was not significant. The difference between the air temperature and the petal or leaf surface temperature did not differ between treatments at the auction stage and consumer stage. The correlation between the shelf life and plant height was positive for all stages. There was no correlation between shelf life and the temperature of the flowers or leaves on auction stage and consumer stage. At the end of the shelf life, there was a high positive correlation between the shelf life and the substrate water content (r = 0.8**), the number of flowers (r = 0.8**) or buds (r = 0.6**), and flowering rate compared to the shipment (r = 0.5*) at the consumer stage. The findings here indicates that the substrate water content affects the postharvest quality and shelf life of potted kalanchoe.

“…Cymbidium is a popular cut flower because of its longevity, various colors, size, and unique floral structure and ranks in the sixth position among the top ten cut flowers in international trade (An et al, 2015;Park et al, 2021). Cymbidium had the highest price at $3.60 per stem among the top 19 species sold in 2018 at the Royal Flora Holland, the world's largest flower market (Faust and Dole, 2021).…”

Here, we tested if nanobubble (NB) and ozone nanobubble (O 3 NB) treatments are effectively prolong the vase life of cut Cymbidium. The cut flowers of the Cymbidium cultivar 'Spring Pearl' were subjected to tap water (TW, control) and two levels of NB and O 3 NB treatments. We investigated the water uptake, relative fresh weight (RFW), senescence rate, petal color, and vase life. The ozone (O 3 ) and dissolved oxygen (DO) concentrations were 0.0 and 10.0 mg•L -1 (TW, control), 0.0 and 16.3 mg•L -1 (NB 20%), 0.0 and 38.3 mg•L -1 (NB 100%), 0.7 and 16.4 mg•L -1 (O 3 NB 20%), and 3.8 and 38.3 mg•L -1 (O 3 NB 100%), respectively. The water uptake and RFW were increased 1.4-fold and 1.7-fold, respectively, in cut Cymbidium treated with O 3 NB 20% on day 2 compared to the control. The a* value of petal color remained green, and the b* value of petal color remained yellow in cut Cymbidium treated with O 3 NB 20% relative to the other treatments. Vase life was prolonged by 1.4 days in cut Cymbidium treated with NB 20% and O 3 NB 20% compared to the control. This study demonstrates that NB 20% and O 3 NB 20% in the vase solution extend the vase life of cut Cymbidium. O 3 NB 20% treatment in the vase solution of cut Cymbidium 'Spring Pearl' resulted in the highest water uptake and RFW, and the lowest senescence rate retaining the vivid color.
