“…The highest vase life (15.75 days) was obtained from applying CaNPs-SA at 2 mM (Figure 4A). Increased vase life span due to solely CaNPs at 5 mM as pulsing treatments and SA at 2 mM has also been reported in cut roses (El-Shawa et al, 2022), as it might be connected to how calcium increases cell resistance by limiting the creation of ethylene (Sardoei, 2014). Additionally, SA functions as an ACC oxidase inhibitor, a direct ethylene precursor (Bayat and Aminifard, 2017;Heidarnezhadian et al, 2017).…”

“…The most significant issues with cut rose flowers in general are neck bending and a short vase life. The primary reason for these issues is that cut flowers lose more water than its uptakes (El-Shawa et al, 2022), in addition to the low percentage of lignin in the region immediately below the flower bud (Perik et al, 2012), and with an increase in ROS and enzyme activity that breaks down cell walls (Reezi et al, 2009), which resulted in an intensification of the problem. So, the main objective of this study was to examine the ability of CaNPs intermixed with SA (1 and 2 mM), besides CaNPs at 2 mM without SA, and the control for enhancing the vase life and visual aesthetic value of R. hybrida cv.…”

“…Nanoparticles gather in diverse tissues due to their smaller diameter, which allows them to pass through cell wall holes and stomatal apertures in leaves (Nair et al, 2010). Many researchers have looked on how well NPs work to prolong the shelf life of cut flowers like gerberas, acacias, and roses ( Lü et al, 2010;El-Shawa et al, 2019;El-Shawa et al, 2022).…”

The vase life of a flower is determined by a variety of factors, including the type of flower, the environment in which it is kept, and the care it receives. The environment in which a flower is kept can also affect its vase life. Two separated experiments were established for examining the efficacy of calcium nanoparticles (CaNPs) intermixed with or without salicylic acid (SA) at different treatments (Control, CaNPs 2 mM, CaNPs-SA 1 mM, and CaNPs-SA 2 mM), as holding solutions on the vase life and postharvest attributes of Rosa hybrida cv. Black Magic cut flowers. The investigation mentioned the influences of CaNPs-SA on some physiological characteristics in roses, including (vase life, flower diameter, relative fresh weight%, flower stem bending index, and water relations). In addition, total phenol content, membrane stability index (MSI), catalase (CAT) antioxidant activity, and cell wall degrading enzymes (CWDAs) such as xylanase (XYL), polygalacturonase (PG), pectinase (PT), and cellulase (CEL) were determined during 10 days of vase life. As well as the generation rates of H2O2, malondialdehyde (MDA), and reduction of DPPH. CaNPs-SA at 2 mM prolonged the vase life and maintained higher relative fresh weight % and water relations. In addition, this superior treatment suppressed the CWDAs, and MDA by promoting the DPPH, and CAT, which increased the MSI of rose-cut flowers. Our study recommends the usage of calcium nanoparticles intermixed with salicylic acid as holding solutions on the vase life and postharvest attributes of Rosa hybrida.

“…They are among the top ten most important cut flowers of economic importance in the international market. Neck or stem bending is one of the most important problems which cause the short vase life in the cut flowers of several rose and gerbera cultivars, which affects their commercial value (Perik et al, 2014;García-González et al, 2022;El-Shawa et al, 2023). Bending is due to bacteria in the preservation solution, which causes the accumulation of microorganisms at or within the stem end and vascular blockages that prevent water from reaching the flower (van Meeteren, 1978;Steinitz, 1983;Van Meetern et al, 2001;Perik et al, 2014;Lear et al, 2022).…”

Bent neck or stem bending is the most essential problem of some cultivars of rose and gerbera cut flowers in the postharvest stage, as it decreases vase life as well as its commercial value. This research was conducted to evaluate the effectiveness of silver nanoparticles (SNPs) at 9 mg/l, 0.2 ml/l thyme oil and 200 mg/l 8-hydroxyquinoline sulfate (8-HQS) as holding solutions and 20 mg/l silver nanoparticles as a pulsing solution compared to distilled water (control) in delaying bent neck in Rosa hybrida cv. Avalanche and stem bending in Gerbera jamesonii cv. Julia cut flowers (these are more cultivars sensitive to bending). Our results indicated a positive effect of SNPs and thyme oil on delaying the bent neck and decreasing bacterial counts. The flowers placed in 9 mg/l SNPs significantly delayed the bending, reduced the number of bacteria, improved water relations, maintained a higher lignin percentage, and extended longevity in both flowers compared to control and other treatments. The results of scanning microscopy pictures of the bending area indicated that 9 mg/l SNPs prevented vessel blockage and maintain anatomical structures such as epidermis cells, parenchyma cells, and vascular bundles in both cut rose and gerbera flowers. The results indicated that SNPs are superior to thyme oil in improving the quality, prolonging vase life, and delaying the bending of rose and gerbera cut flowers.
