“…It has been reported that B light can act synergistically on biosynthesis and accumulation of carotenoids. For instance, the accumulation of carotenoids was provoked by B light during the vase life of carnation plants [65]. It has also been shown that plants contain high carotenoid concentrations when they are grown under high B to R ratios [31], which confirms the findings of the current study on the positive effect of B light on increasing carotenoid concentration.…”

Saffron is a valuable plant and one of the most expensive spices worldwide. Nowadays, there is a tendency to produce this crop in indoor plant production systems. However, the production of saffron is restricted by the need for the reproduction of high-quality corms. In this study, we investigated the effect of different ratios of red (R) and blue (B) light spectra (including 100% B (monochromatic B), 75%, 50%, 40%, 25% B, and 0% B (monochromatic R) on the photosynthetic performance and biomass partitioning as well as morphological and biochemical characteristics of saffron. The growth of flower, root, and corm was improved by increasing the proportion of B to R light. B-grown plants were characterized by the highest photosynthetic functionality with efficient electron transport and lower energy dissipation when compared to R-grown plants. B light directed biomass toward the corms and floral organs, while R light directed it toward the leaves. In saffron, the weight of a daughter corm is of great importance since it determines the yield of the next year. As the ratio of B to R light increased, the daughter corms also became heavier, at the cost of reducing their number, though increasing the proportion of B-enhanced antioxidant capacity as well as the activity of ascorbate peroxidase and catalase while superoxide dismutase activity was enhanced in R-grown plants. In conclusion, B light increased the production of high-quality daughter corms and altered biomass partitioning towards harvestable organs (corms and flowers) in saffron plants.

“…In this study, leaf MDA content increased with the duration of storage (Figure 8B), and this increase was associated with leaf H2O2 content (Figure 8A). An increase in membrane lipid oxidation owing to cold storage-induced ROS elevation has been earlier reported [3,4,14]. This study for the first time shows that the membrane lipid oxidation level was associated with cultivar sensitivity to cold storage (Figures 1A and 8B).…”

“…In cut flowers, dark refrigerated storage has been associated with oxidative stress [3,4,14], which elicits a range of adverse effects, including lipid peroxidation [15]. The associated symptomatology is often undetectable during storage, and expressed later in the marketing chain [16].…”

“…The associated symptomatology is often undetectable during storage, and expressed later in the marketing chain [16]. Oxidative stress is triggered by the imbalance between the accumulation of reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), and the antioxidant elements [4,14,15]. Polyphenolics and flavonoids are critical non-enzymatic antioxidant elements detoxifying ROS [17][18][19].…”

The Role of Water Relations and Oxidative Stress in the Vase Life Response to Prolonged Storage: A Case Study in Chrysanthemum

Long storage periods have been associated with decreased vase life. In this study, the processes underlying the vase life response to prolonged storage were investigated, along with the potential of light reflectance profiles to estimate storage duration. Three cut chrysanthemum cultivars were exposed to four cold (5 °C) storage periods (0, 7, 14, and 21 d). Stomata were present on the leaves (either side) and stem, but not on petals. As compared to the leaves, stomata on the stem were non-functional, smaller, and less dense. Floral transpiration was a small portion of the whole-cut flower transpiration, with the major contributor being the leaves or stem depending on the cut flower hydration. Storage duration linearly decreased vase life, with the rate of decrease being cultivar specific. Storage duration (0–21 d) did not affect leaf stomatal functioning, non-leaf tissue transpiration, or the relative contribution of each organ to the whole-cut flower transpiration. Cut flower hydration was generally enhanced by storage, while water uptake restoration ability was not impaired. Membrane lipid oxidation increased in response to storage duration owing to enhanced H2O2 accumulation. A strong correlation between membrane lipid oxidation level and the vase life response to cold storage was apparent. By examining the light reflectance profiles (400–1050 nm) of leaves (either side) and flowers (top view), an indication of the storage period could not be deduced. In conclusion, cultivar differences in vase life response to cold storage were attributed to variation in oxidative state, whereas cut flower water relations are clearly not involved.

“…Senescence is a complex, critical, and coordinated event that determines the longevity of cut flowers (Wu et al, 2017;Aalifar et al, 2020). The final phase of flower vase life, for instance, is characterized by time-dependent petal wilting, flower withering (Su et al, 2019), and flower or petal abscission (Van Doorn, 2001).…”

Selenium-Ethylene Interplay in Postharvest Life of Cut Flowers

Selenium (Se) is considered a beneficial element in higher plants when provided at low concentrations. Recently, studies have unveiled the interactions between Se and ethylene metabolism throughout plant growth and development. However, despite the evidence that Se may provide longer shelf life in ethylene-sensitive flowers, its primary action on ethylene biosynthesis and cause-effect responses are still understated. In the present review, we discuss the likely action of Se on ethylene biosynthesis and its consequence on postharvest physiology of cut flowers. By combining Se chemical properties with a dissection of ethylene metabolism, we further highlighted both the potential use of Se solutions and their downstream responses. We believe that this report will provide the foundation for the hypothesis that Se plays a key role in the postharvest longevity of ethylene-sensitive flowers.
