“…Some research took approaches based on substrate properties, such as using soil moisturizing agents to enhance soil moisture retention (Kwon et al, 2022). Studies have also been carried out to determine the optimal irrigation timing based on the measurement of volumetric water content (VWC) using automated irrigation systems (Nam et al, 2017;Nam et al, 2018). In the subject of smart farming, technologies using Information and Communication Technology (ICT) have been introduced to maximize production by increasing water use efficiency and detecting and addressing anomalies in soil moisture, pH, and soil types (Jung and Lee, 2021;Ramachandran et al, 2018).…”

Background and objective: The present research study aimed to investigate the optimum substrate volumetric water content (VWC) needed for Farfugium japonicum (L.) Kitam. to maintain its performance in the indoor garden.Methods: The threshold levels of substrate VWC were evaluated as 0.1, 0.2, 0.3 or 0.4 m3⋅m-3 using an automated irrigation system with capacitance soil moisture sensors and datalogger. Plant growth and physiological responses were measured and analyzed at 10 weeks after treatment. Plant growth was investigated by measuring survival rate, plant height, leaf length, leaf width, leaf number, root length, fresh and dry weight of shoot and root. Physiological responses were observed by analyzing antioxidant enzymes (SOD, POD) and antioxidants (MDA, proline), maximum quantum yield (Fv/Fm) and total chlorophyll contents.Results: The results of drought tolerance measurement by the treatment group showed that the overall growth was the highest in the 0.3 and 0.4 m3⋅m-3 treatment plot and the lowest in the 0.1 m3⋅m-3 treatment plot. Under the droughtstressed condition of the 0.2 m3⋅m-3 treatment, growth was not as efficient as the 0.3 and 0.4 m3⋅m-3 treatments due to the relatively higher moisture content, but there was no statistical difference between the 0.3 and 0.4 m3⋅m-3 treatments in the maximum quantum yield (Fv/Fm) and also total chlorophyll content. Furthermore, for antioxidant activities, SOD, POD, and MDA showed high values, but no statistical differences were found among treatments except for the 0.1 m3⋅m-3 treatment, which was under severe drought stress in terms of proline.Conclusion: Overall, the results indicate that Farfugium japonicum (L.) Kitam., has a tolerance to drought, and for managing indoor gardens the adequate soil moisture content for the growth is at least 0.2 m3⋅m-3 assuming the use of identical substrate in this experiment.

“…Furthermore, an ongoing study is investigating sustainable value chains, aiming to reduce the degradation of quality in potted flowers from production to distribution (Havardi-Burger et al, 2020). Despite increasing consumer demand, few studies have focused on the post-production management of potted hydrangea, with the majority of active studies focusing on the cultivation, quality improvement, and post-harvest control methods of cut hydrangea (Lee et al, 2017;Nam et al, 2017;Lee and Lee, 2018;Lee et al, 2019).…”

This study compared the shelf life and quality of potted hydrangea ('Speedy Red') treated with different abscisic acid (ABA) spray concentrations and investigated the associated physiological changes. Plants were treated with 0 (control), 1,000, 2,000, or 2,500 mg•L -1 ABA, which was applied by spraying. Treatment with 2,000 and 2,500 mg•L -1 ABA extended the hydrangea shelf life by 2 days compared to the control, and the 2,000 mg•L -1 treatment attenuated change in sepal color and wilting compared to other treatments, suggesting quality control in potted plants. Additionally, the 2,000 mg•L -1 ABA spray treatment increased stomatal closure up to day 5 post-treatment, corresponding to the end of the shelf life for treated plants, indicating that ABA spray decreased transpiration-induced water loss. The 2,000 mg•L -1 ABA spray treatment resulted in the highest maximum quantum yield of PSII among the treatments, and the normalized difference vegetation index and the simple ratio index values were also higher than those obtained with other treatments. Thus, 2,000 mg•L -1 ABA spray treatment mitigated water stress by inducing stomatal closure in potted hydrangea ('Speedy Red'). Overall, the ABA spray treatment controlled stomatal closure and effectively inhibited transpiration, which minimized water loss and preserved plant moisture levels, thereby extending shelf life and quality. Our study also assessed the potential use of nondestructive measurements (e.g., chlorophyll fluorescence and vegetation indices) to monitor the quality of potted hydrangea, which may facilitate the evaluation of potted flower quality on site.ABA spray treatment at 2,000 mg•L -1 effectively extends the shelf life and improves the quality of potted hydrangea ('Speedy Red'). These results are useful for the postharvest management of potted hydrangeas.
