“…These differences among the treatments in shelf -life period due to the roles of each preservative solution separately in encouraging cell elongation, cells divisions and consequently decreasing activation of photosynthesis and metabolic process which reflected increases in life period longevity. Data showed harmonized trend Avilala et al, (2021), Skutnik et al, (2021) and El-Attar and Sakr (2022).…”

A laboratory experiment was conducted to study the effect of Nano-silver, benzyl adenine, chitosan and glycerol as chemical preservative solutions on enhancing properties of Nephrolepis exaltata vegetative branches. Nine individual applications (Nano-silver at 15 and 20 mg/L, benzyl adenine 10 and 20mg/L, chitosan 0.5 and 1.0 g/L as well as glycerol 1.0 and 2.0 cm/L) and control. Moreover adding sucrose at 5.0 gm/L + citric acid 150 mg/L + 0.5 ml of Tween 20 to all treatments mentioned above. At the end of the experiments there were some trends cleared as the maximum shelf-life period presented with glycerol at 2.0 cm/L, in both seasons. Nano-Silver at 15.0 mg/L treatment gave the higher water uptake percentage, while benzyl adenine at 10.0 mg/L was the pioneer in water loss, even Nano-silver at 15mg/L had the highest water balance. Chlorophyll a (mg/g) after 5 days was highest with Nano-silver at 15 mg/L, but got highest with Nano-silver at 20mg/L after ten days. Chlorophyll b (mg/g) after five days was maximum with glycerol at 1.0cm/L, but chitosan at 0.5gm/L got highest with Nano-silver at 20mg/L after ten days. Glycerol at 2.0cm/L was the highest percentage in the day matter after five days. Chitosan at 1.0gm/L was the maximum percentage in the day matter after ten days. Total sugar was the pioneer in Nano silver at 20mg/L after five and ten days. However, chitosan at 0.5gm/L gave the maximum microbial growth after five and ten days.

“…Lilium (Liliaceae family) is an important commercial cut flower in the international market due to its long vase life compared to other cut flowers (Nukui et al, 2004) a major characteristic demanded commercially. The cut flower with a lengthier shelf life is considered a significant quality trait in flower cultivation and is preferred by retailers in domestic and export markets (Avilala et al, 2021).The post-harvest life of a cut-flower is influenced by different factors (Mayak et al, 1974;Ichimura et al, larger transpiration level compared to the level of water intake (Halevy and Mayak, 1981). Occlusions, located primarily in the basal end, are often correlated with a lower level of water uptake (He et al, 2006).…”

Lilium cut flowers have commercial importance and extending their vase life is vital. An increase in the vase life quality and quantity can directly increase the viability and price realization of commercially important flowers like lilium. Shelf life of cut lilium flower is influenced by using different preservative chemicals and sucrose added in vase solution. Such an extension of vase life can be achieved via chemical treatment. The trial was carried out to examine the effect of various concentration of two chemicals, AgNO3 (silver nitrate) and 8-HQC (8-Hydroxyquinoline citrate) along with sucrose on the shelf life of lilium cut flower cv. ‘Pavia’ (cross between Asiatic and Longiflorum lilies). In the experiment, sucrose (20%), 8-HQC at 3 concentrations (100, 150, 200 ppm) and AgNO3 at 3 concentrations (50, 75, 100 ppm) and water (distilled) as control were tested alone and with combinations. Cut flowers of lilium were treated at one bud opening stage. The trial was carried out in a completely randomized design (CRD) having 16 treatments and one control in three (3) replications. The fresh weight and relative fresh weight of the cut flower spike, opening of all flowers on a spike, vase solution uptake on a day, total vase solution uptake and vase life of lilium cut flower spike showed the best outcome with AgNO3 (50 ppm) and 20% sucrose treatment combination. Out of the two chemicals, silver nitrate showed better results than 8-HQC as a preservative in enhancing the shelf life of cut Lilium flower cv. ‘Pavia’. Analysis of this new and exciting method will be useful to research institutes, commercial producers, wholesalers, retailers, consumers or anyone to choose right chemical and concentration of holding solution to maximize the post-harvest life of lilium cut flowers.

Synergistic effect of graphene oxide and silver nanoparticles as biostimulant improves the postharvest life of cut flower bird of paradise (Strelitzia reginae L.)

The bird of paradise (Strelitzia reginae L.) is one of the important tropical cut flowers. Generally, flowers like bird of paradise (BOP) grown for the commercial ornamental market must be of high pre and postharvest quality. Thus, to improve the postharvest longevity and increase marketability, the relative efficacy of two different biologically synthesized nanoparticles (NPs) was evaluated. The novel proprietary stimulants were graphene oxide (GO) and silver nanoparticles (SNPs). The NP treatments were applied as a vase (lower concentrations) solutions. Among all the applied treatments, the synergistic effect of GO + SNPs at 1 µL L−1 vase solution significantly (p =0.05) prolongs the post-harvest life of cut flowers of BOP. Increased vase life over the deionized water (DI) control was associated with better maintenance of relative water uptake, relative fresh weight, suppressed microbial density at stem-end and delay of stem blockage, reduced electrolyte leakage, malondialdehyde (MDA), SOD, and POD activity. In contrast to control, administration of NPs gave better results for all analyzed parameters. Application of biologically synthesized NPs in combination (GO + SNPs at 1 µL L−1) extended the vase life of cut flowers by 6 days compared with control flowers, and overall, showed better results than the control. The findings of the studies revealed that the standardized NPs could have more potential in prolonging the postharvest life of cut flowers in BOP. Thus, this technique can be used as a novel postharvest technology for commercial application in cut flowers.
