“…The preservative solution containing AgNO3 (250 ppm) + sucrose (3%) not only increase vase life but also helps in improving flower opening percentage, days to open basal floret, bloom spread, floret length, floret diameter, floral spike fresh and dry weight, and fresh weight loss. Similarly pulsing of cut flowers with sucrose and biocides combination increased floret opening in lisianthus (Kiamohammadi and Hashemaabadi, 2011), bird of paradise (Gendy and Hamad, 2011), orchid (Mattiuz et al, 2015), tuberose (Kumar and Deen, 2017) and gladiolus (Casares et al, 2017). Like floret opening percentage, Ahmed et al (2018) observed that biocide (Aluminium sulphate) and sucrose induce early opening of basal florets in Gladiolus hybridus.…”

Gladiolus is an important cut flower in the world, and its preference in Pakistan is next to roses. But the main problem that occurs in gladiolus is that it has short vase life. The present experiment was conducted with an objective to investigate the effect of four preservative solutions [distilled water, Sucrose (3%), AgNO3 (250 ppm), AgNO3 (250 ppm) + Sucrose (3%)] and packaging material on postharvest quality of three gladiolus varieties, “Tissue, White Prosperity and Alexandra”. Packaging material consists of control treatment (without packaging), packaging of cut spikes with 100 ppm acetic acid soaked cotton and packaging of polyethylene sheet after sucrose pulsing. The experiment was arranged as two factorial laid out according to completely randomized design (CRD) having three replications. Results showed that preservative solution having combination of AgNO3 (250 ppm) + Sucrose (3%) significantly improves days to open basal floret, floret opening percentage (%), bloom spread (inch), floret length (inch), floret diameter (inch), fresh spike weight (g), dry spike weight (g), fresh weight loss (%) and vase life (days). Moreover, this treatment was also effective in reducing the wilting (%) in all gladiolus varieties. However, for solution uptake (mL/spike) and solution balance (ml/spike), AgNO3 (250 ppm)alone gives the best results. For packaging treatment, the pulsing of a cut spike with 20% sucrose followed by polyethylene sheet wrapping proves to be effective. Among the varieties, Alexandra performed better for all quality parameters in comparison to White Prosperity and Tissue

The use of postharvest coatings of fruits and vegetables has been the subject of many studies for their ability to extend the shelf life of vegetables. However, little is known about the effect of coatings on postharvest of cut flowers. We evaluated the effect of different concentrations of natural coating based on hydroxypropyl methylcellulose (HPMC) and beeswax (CA) on postharvest of cut roses. White rose cultivar ‘Avalanche’ obtained from commercial production at the bud stage were used. The coating was prepared by the combination of the hydrophilic phase (HPMC) and the lipid phase (CA) suspended in water, resulting in 50g lipids / 100g emulsion. The emulsion was sprayed on the flowers in different volumes: 0 (distilled water); 1.5; 3.0 and 4.5 mL rose-1. The roses were maintained at 20 ± 1 °C and RH> 70% for 9 days for physiological analysis and 12 days for vase life. Data were collected every 3 days for accumulated of fresh mass, water absorption, relative water content (RWC), membrane stability index (MSI) and vase life. The application of 3.0 mL/rose of the coating resulted in higher RWC and MSI throughout the storage time. We conclude that the use of a natural coating of HPMC/beeswax sprayed at 3.0 mL / rose increased the vase life of the ‘Avalanche’ rose by 2 days.

“…In Heliconia wagneriana, a 10% sucrose pulsing for 60 minutes maintained the quality of the inflorescences 20% longer than in control stems that had high transpiration and low water consumption (Costa et al, 2015). In Oncidium varicosum orchids a 5% sucrose + 100 mg L -1 8-HQC + 50 mg L -1 AgNO 3 vase solution maintained the relative water content and the carbohydrates and soluble sugars content in the flowers, thus preserving the vase life for longer compared to stems of a control treatment (Mattiuz et al, 2015).…”

Heliconia ‘Tropics’ has high market acceptance and blooms year-round. Still, there is little information on solutions to prolong its vase life. The objective of this research was to assess pulse solutions to prolong the vase life of Heliconia ‘Tropics’ in three cutting stages. Floral stems in a closed, semi-open and commercial grown stages from three years old plants grown in an outdoor setting were evaluated. Three experiments were evaluated: sucrose at 10, 20 and 30% (w/v); Hydraflor® 100 at 0.25, 0.50 and 0.75 g L-1; and citric acid (CA) at 25, 50, 100, 150 and 200 ppm, and a control (tap water). The floral opening, fresh weight of the floral stems, solution consumption and vase life were measured every two days. Based on the best results of these experiments, the following combinations were assessed: 10% sucrose + 0.50 g L-1 Hydraflor® 100; 10% sucrose + 150 ppm CA; 10% sucrose + 0.50 g L-1 Hydraflor® 100 + 150 ppm CA; 0.50 g L-1 of Hydraflor® 100 + 150 ppm CA and a control. A 10% sucrose + 0.50 g L-1 of Hydraflor® 100 pulse for 24 h had a 22.8-day vase life and was superior to the floral stems in the control treatment (15.6 days) at the semi-open cut stage. This was associated with greater water consumption, lower fresh weight loss and greater floral opening.
