“…Between day 0 and day 14, the Fv/Fm was higher for the foliage conditioned in a solution of 5 mg dm −3 nanosilver with sucrose than that for the controls. The obtained results are in line with those reported by Jowkar et al (2013), who measured the longevity of the flower stems of Rosa hybrida 'Cherry Brandy' and found a positive effect of nanosilver on Fv/Fm, although they used significantly higher concentrations of nanosilver (10 g dm −3 ) than those used in this work. In Matthiola incana (Ferrante et al, 2009) and Peoania lactiflora (Michałek et al, 2006), a significant decrease in Fv/Fm was observed in the control foliage (held in distilled water), which was not observed in the present study of Thalictrum aquilegifolium.…”

“…In Dianthus caryophyllus 'Pinkcastellaro, ' a positive effect on the content of assimilative pigments was noted after using nanosilver at a concentration of 10 mg dm −3 (Hamidimoghadam et al, 2014). Jowkar et al (2013) found that cuttings of Rosa hybrida 'Cherry Brandy' stems treated with high concentrations of nanosilver (50 and 25 g dm −3 ) presented significantly higher chlorophyll content than that in control stems treated with distilled water. Byczyńska (2017) reported that the cut leaves of Aspidistra elatior conditioned in nanosilver solution showed significantly higher greening index values than the controls, regardless of the nanosilver concentration, whereas Solgi et al (2009) reported that nanosilver at concentrations of 25 and 50 mg dm −3 did not significantly affect the chlorophyll content of Dianthus caryophyllus.…”

“…Nanosilver was also found to limit wilting and accelerate flowering in Polianthus tuberosa (Bahrehmand et al, 2014) and Rosa hybrida 'Royal' (Mortazavi et al, 2011) and inhibited water loss in Rosa 'Movie Star' (Lü et al, 2010). According to Jowkar et al (2013), nanosilver treatment resulted in an increase in the chlorophyll content of Rosa hybrida 'Cherry Brandy. ' However, it is worth remembering that sucrose should be used together with the nanocompounds in the conditioning solutions because cut flowers are subjected to a rapid drop in the level of sugars, which can significantly shorten their longevity (Bahrehmand et al, 2014).…”

The Effect of Nanosilver on Postharvest Longevity of Thalictrum aquilegifolium L. Foliage

Thalictrum aquilegifolium L. ‘Black Stockings,’ with its interesting foliage, is used as a cut greenery. We tested the postharvest longevity of the foliage after different 24-hr conditioning treatments with nanosilver (0, 5, 10, 15, 20 mg dm−3) and 20 g dm−3 sucrose and compared the results with those obtained using the standard preservative (200 mg dm−3 8-hydroxyquinoline citrate + 20 g dm−3 sucrose) and Floralife 200 Clear. The longevity of the foliage and the content of assimilative pigments were evaluated and the functioning of the photosynthetic apparatus (F0, Fm, Fv/Fm) was analyzed. We found that leaf senescence, as determined by chlorophyll a and carotenoid content after 14 days of holding, was most effectively inhibited by the solution containing 5 mg dm−3 nanosilver and sucrose. This solution increased the maximal quantum efficiency of photosystem II (Fv/Fm) in the leaves.

“…This beneficial effect of sucrose, in combination with the biocidal, chelating and stomatal closing properties of 8-HQS (8-hydroxyquinoline sulphate) may have promoted the cut flower cellular integration. Chemicals with biocidal activities may be promoting cut flower quality due to their inhibitory effect on microbial growth, hence promoting water uptake that sustains metabolic activities (Jowkar et al, 2013).…”

Several biochemical and metabolic changes are associated with senescence of cut gladioli, particularly in relation to quality characteristics, including dynamism of carbohydrates. The objective of this study was to evaluate the effect of pulsing and wet cold storage on the starch and sugar biomarkers on cut Gladiolus (Gladiolus grandiflorus L. cv. Fado) vase quality. Pulsing treatments of 600-ppm 8-hydroxyquinoline sulphate, plus 5% sucrose solution, versus distilled water, were administered prior to wet cold storage durations of 0 - 5 days, on the cut Gladiolus grown from corms. This was done in the open field at the Horticulture Research and Teaching Field, Egerton University in Kenya, during two successive seasons. There was a significant difference (P <0.01) in total soluble sugars (TSS) and total starch of spikes pulsed with 600 ppm 8 - HQS + 5% sucrose, compared with the control, during the third day in the vase life of the cut flowers. Prolonged vase life of cut spikes was associated with a decrease in total soluble sugars and increase in total starch, as influenced by pulsing and wet storage duration up to 4 days.

“…Generally, with increasing concentration of Al2(SO4)3, vase life decreased progressively. According to Jowkar et al (2013b) Al2(SO4)3 maintains membrane permeability, increases chlorophyll content and freshness of flowers and leaves of roses. De Witte et al (2014) reported that stem bending of gerbera hastens at a high concentration of antimicrobial compounds.…”

Cut rose stems were pretreated for 24 h with various compounds before being stored in Chrysal solution. Two experiments were conducted to study the effects of different concentrations of aluminum sulphate, ethanol and sucrose in preservative solutions and their combination on flower longevity and post-harvest physiological properties of rose (Rosa hybrida L.) cut flowers cultivars ‘Red Sky’ and ‘Blizzard’. The first experiment aimed to determine the optimum concentration of aluminum sulphate used as a biocide (0, 0.5, 1, 1.5 g·dm−3), ethanol used as a biocide and anti-ethylene factor (0, 4, 8, 12%) and sucrose used as a source of energy (0, 10, 20, 30 g·dm−3). In the second experiment, the most effective concentrations were cumulated in combinations of pretreatment solutions. Single use of chemicals: 0.5 g·dm−3 aluminum sulphate, 4% ethanol and 20 g·dm−3 sucrose extended the longevity of both cultivars by 17, 18 and 19%, respectively as compared to deionized water. In the second experiment, the preservative solution containing all three chemicals at optimal concentrations extended cut flower longevity by 30% compared to deionized water. ‘Blizzard’ has lost its commercial value by 6.6% of the time earlier than ‘Red Sky’. Generally, using a biocide, anti-ethylene and source of energy in a pretreatment solution can maintain the high quality of the cut rose flowers and their vase life.
