“…Oxidative stress is one of the most important factors that affects both the life of flowers and the quality of cut flowers. Oxidative stress affects cell mechanisms and membrane lipids, accelerating senescence, which is why avoiding or reducing oxidative stress is crucial to increasing the lifespan of flowers [17]. Therefore, an adequate antioxidant defense system can increase the shelf life of flowers, as observed in this study of the application of SiO 2 NPs.…”

The production of ornamentals is an economic activity of great interest, particularly the production of Lilium. This plant is very attractive for its color and shapes; however, the quality of its flower and its shelf life can decrease very fast. Therefore, it is of the utmost importance to develop techniques that allow for increasing both flower quality and shelf life. Nanotechnology has allowed for the use of various materials with unique characteristics. These materials can induce a series of positive responses in plants, among which the production of antioxidant compounds stands out. The objective of this study was to determine the impact of the application of silicone nanoparticles (SiO2 NPs) on the quality, shelf life, and antioxidant status of Lilium. For this, different concentrations of SiO2 NPs (0, 200, 400, 600, 800, and 1000 mg L−1) were applied in two ways, foliar and soil, as two independent experiments. The contents of enzymatic (superoxide dismutase, glutathione peroxidase, catalase, ascorbate peroxidase, and phenylalanine ammonia lyase) and non-enzymatic (phenols, flavonoids, and glutathione) antioxidant compounds, the mineral content, flower quality, and shelf life were analyzed. The results showed that the application of SiO2 NPs through the foliar method induced a greater flowers’ shelf life (up to 21.62% more than the control); greater contents of Mg, P, and S (up to 25.6%, 69.1%, and 113.9%, respectively, compared to the control); more photosynthetic pigment (up to 65.17% of total chlorophyll); more glutathione peroxidase activity (up to 69.9%); more phenols (up to 25.93%); and greater antioxidant capacity as evaluated by the DPPH method (up to 5.18%). The use of SiO2 NPs in the production of Lilium is a good alternative method to increase flower quality and shelf life.

“…A study on gladiolus has shown that a 2% concentration of Calotropis procera leaf extract (CPLE) extends the maximum vase life up to 14.5 days, open florets (64%) and RFW (40%) compared to the effects of Moringa oleifera leaf extract (MOLE) and Mentha piperita leaf extract (MPLE). Therefore, CPLE at 2% appears to be an effective natural preservative to extend the vase life of gladiolus cut spikes [122].…”

Cut flowers have become an export income in the global floriculture market. They have multiple uses, such as for home beautification, in ceremonies (including weddings and funerals), and as symbols of love, appreciation, respect, etc., in humane society. Each type of cut flower has a different vase life and the longevity of their freshness is linked to preharvest, harvest, and postharvest tools and conditions. The postharvest quality and vase life must be considered in order to obtain the desirable qualities of cut flowers, and factors that affect this are important in the floral industry. The use of floral preservative solutions is good practice for prolonging the vase life of cut flowers. Currently, the eco-friendly solutions, which are used as floral preservatives for extending cut flower vase life, have been discovered to be a low-cost and organic alternative as compared to chemical solutions. However, there are certain problems associated with the use of chemical and eco-friendly solutions. In this review, we summarize several potential approaches to improve flower vase life and discuss the best choices for holding-preservative-solution practices.

“…This vessel blockage can be induced by the formation of air bubbles in the vascular system (Van Doorn, 2013), the rapid proliferation of microorganisms, and the plant response to wound cutting (Van Doorn, 2013;Li et al, 2017). Several post-harvest treatments have been recommended for enhancing water uptake and increasing the vase-life of cut flowers, including the application of germicide and chemical preservatives (Akhtar, et al, 2021). These preservatives must include particularly multi components, germicides and sugar (Akhtar, et al, 2021).…”

“…Furthermore, NS particles treatment significantly suppressed the expression levels of ACS1 and ACO1 genes of ethylene biosynthesis pathway as well as petal senescence-related gene (CP1), resulting in significantly extended vase life of carnation flower (Naing et al, 2017;Park et al, 2017;Naing et al, 2021). Furthermore, the use of non-chemical alternatives such as plant essential oils recently has become a common practice in the postharvest pathogen control due to environment-friendly and antimicrobial characteristics (Akhtar et al, 2021).…”

Vase life consequences of natural and chemical treatments in foxtail lily (Eremurus spectabilis), as a specialty cut flowers

et al. 2022

Eremurus spectabilis is a new, commercially valuable specialty cut flower, but little is known about the applicable treatments to extend the vase-life and maintaining the ornamental quality of this flower. Therefore, the present study was aimed at investigating the impacts of nano-silver, essential oils, and chemical treatments on keeping ornamental quality and vase-life of cut inflorescences of Foxtail lily. The cut inflorescences were placed in different vase solutions containing salicylic acid (100 and 200 mg L-1), methyl jasmonate (25 and 50 mg L-1), silver thiosulfate (0.1 mM) plus isothiazolinone (0.001 and 0.005 mL L-1), nano-silver (5, 10, and 15 mg L-1), thymol (75 and 120 mg L-1), and menthol (75 and 120 mg L-1), which were applied as continuous and pulsing methods. According to the results, all treatments considerably improved the post-harvest performance of Foxtail lily cut flowers. Although there were no significant differences among nano-silver (NS) treatments, the cut inflorescences kept in vase solution containing 10 mg L-1 of NS exhibited the longest vase life (~14 days) and the best ornamental quality. Nano-silver treatment followed by silver-thiosulfate significantly improved solution uptake by flowering inflorescences, thereby delaying the water balance loss and keeping relative fresh weight. Furthermore, 50 mg L-1 methyl jasmonate- and 75 mg L-1 menthol-treated cut inflorescences exhibited significantly higher vase-life longevity by ~ 6 and 4 days, total soluble solutes by 28.38% and 19.12%, and solution uptake rate by 76.46% and 140.6%, respectively, as compared to control. Overall, 10 mg L-1 NS can be recommended as a commercial preservative solution to delay flower senescence and improve the vase life and keeping the quality of foxtail cut inflorescence.
