AbstractCut 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.

Six experiments were conducted using three cultivars to investigate the impact of water electrical conductivity (EC) and the addition of nutrients to vase solutions on postharvest quality of cut rose (Rosa hybrids) stems. Postharvest quality of cut ‘Freedom’ rose stems was evaluated using solutions containing either distilled water with sodium chloride (DW+NaCl) or DW+NaCl with the addition of a commercial floral preservative (holding solution containing carbohydrates and biocide) to generate a range of EC values (Expts. 1 and 2). The third experiment compared the effect of different EC levels from the salts NaCl, sodium sulfate (Na2SO4), and calcium chloride (CaCl2). The fourth experiment investigated EC’s impact on rose stems with the addition of two rose cultivars (Charlotte and Classy). When ‘Freedom’ stems were subjected to DW+NaCl, the longest vase life was achieved with 0.5 dS·m–1. The addition of holding solution not only extended vase life but also counteracted the negative effects of high EC with maximum vase life occurring at 1.0 dS·m–1. Furthermore, stems in the holding solution experienced significantly less bent neck and the flowers opened more fully than those in DW. Stems placed in DW with a holding solution also experienced more petal bluing, pigment loss, necrotic edges, and wilting than those held in DW alone. This effect was likely due to increased vase life. Salt solutions containing Na2SO4 and CaCl2 resulted in extended vase life at 1.0 dS·m–1, but increasing salt levels decreased overall vase life. As EC increased, regardless of salt type, water uptake also increased up to a maximum at 0.5 or 1.0 dS·m–1 and then continually declined. Maximum vase life was observed at 1.5 dS·m–1 for cut ‘Charlotte’ stems, and at 1.0 dS·m–1 for ‘Classy’ with the addition of a holding solution. Physiological effects were different based on cultivar, as observed with Charlotte and Freedom flowers that opened further and had less petal browning than Classy flowers. ‘Freedom’ had the greatest pigment loss, but this effect decreased with increasing EC. Further correlational analysis showed that in water-only solutions, initial and final EC accounted for 44% and 41% of the variation in vase life data, respectively, whereas initial pH accounted for 24% of variation. However, the presence of carbohydrates and biocides from the holding solution was found to have a greater effect on overall vase life compared with water pH or EC. Finally, in Expts. 5 and 6, cut ‘Freedom’ stems were subjected to DW solutions containing 0.1, 1, 10, or 100 mg·L–1 boron, copper, iron, potassium, magnesium, manganese, or zinc. None of these solutions increased vase life. Conversely, 10 or 100 mg·L–1 boron and 100 mg·L–1 copper solutions reduced vase life. Finally, the addition of NaCl to a maximum of 0.83 dS·m–1 increased the vase life in all solutions. These analyses highlight the importance of water quality and its elemental constituents on the vase life of cut rose stems and that the use of a holding solution can overcome the negative effects of high EC water.

Narcissus, belonging to Amaryllidaceae family, is one of the emerging cut flower in ornamental industry. Appropriate cut flower packaging for ideal time period provides potential benefit of improving their post-harvest quality of flower. Current research was conducted with an objective to find out best suitable packaging materials and optimum storage duration for cut flowers of narcissus. Narcissus postharvest features were analyzed statistically and results showed significant difference among the treatments with respect to packaging material as well as storage duration. In our findings, polyethylene sleeve showed best results in most of postharvest parameters (vase life, total life, dry weight, and change in fresh weight). In our results, 2 hours duration of storage significantly improved the post-harvest parameters of cut Narcissus. Vase life, fresh and dry weight of flower obtained maximum value in two hours storage duration. It was interesting to note that as storage duration increased, post-harvest characters reduced. In conclusion, postharvest quality of cut Narcissus can be improved significantly by using suitable packaging material and optimizing storage duration.

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
