Preservative Solutions

Short vase life and post-harvest losses of cut flowers are major threat to floriculture industry. There are different preservative solutions that have been used to extend the post-harvest life of cut flowers. Hence, this study was executed at Floriculture laboratory of Ayub Agricultural Research Institute, Faisalabad during 2018-2020 to explore the efficacy of different preservative solutions on vase life and post-harvest quality of cut roses. There were 6 treatments viz, (T1= Distilled water, T2= Silver nitrate @ 100 ppm, T3= 8-Hydroxyquiroline citrate @ 100 ppm, T4= Sodium thiosulphate @100 ppm, T5= Sodium benzoate @100 ppm, T6= Sucrose @ 40 g/L) and two rose cultivars Kardinal and Gold medal. The experiment was arranged according to complete randomized design (CRD). Results designated that longest vase life (15 days), maximum soluble solid contents (9.3 Brix) and longest opening period (7.4 days) were acquired with silver nitrate @100 ppm solution while maximum flower size (6.77 cm2) and largest head diameter (8.6 cm) were achieved with sodium thiosulphate when applied at the rate of 100 ppm in cultivar Kardinal. All other chemical solutions also displayed positive effects. Keeping in view the remarkable impact of Silver nitrate on vase life and quality of cut roses, it is recommended for commercial growers and cut flower industry for preservation of cut roses for longer time.

Preservative Solutions

The short vase life is the major problem in the cut flower industry. This study was conducted to evaluate the role of different vase solutions and oils in enhancing the quality and vase life of lily cut flowers. Salicylic acid (SA; 300 mg L−1), citric acid (CA; 300 mg L−1), gibberellic acid (GA; 100 mg L−1), and clove oil (200 mg L−1) were used as vase solutions. These treatments were applied after pulsing with preoptimized sucrose 5%. It was found that SA (300 mg L−1) + sucrose (5%) improved the performance of cut flowers, which further increased the longevity of all tested lily cultivars up to eight days and the longest vase life by 17.6 days. The maximum change in fresh weight (5.60 g), increase in chlorophyll contents (3.2 SPAD value), highest protein content (6.1 mg g−1 FW), and increase in the activities of superoxide dismutase (SOD) (51.0 U g−1 protein), catalase (CAT) (36.3 U g−1 protein), and peroxidase (POD) (41.6 U g−1 protein), were recorded with the CA (300 mg L−1) + sucrose 5%. Among the cultivars, “Zambesi” performed best compared to “Sorbonne” and “Caesars”. The maximum anthocyanin contents (198%) were recorded in “Caesars”. In conclusion, among the different preservative solutions, SA performed best to prolong the vase life and quality of lily cut flowers.

Post Harvest

Chrysanthemum (Dendranthema grandiflora) is an ornamental plant that has high economic value, including flowers that are in great demand at domestic or abroad.  As cut flowers, chrysanthemums are used for decoration and flower arrangements at weddings, and for opening new offices.  The quality of cut flowers depends on the appearance and durability of freshness. Flowers with prime quality have a higher sale value compared to low-quality cut flowers. To maintain the quality of prime cut flowers still need to be implemented several treatments, especially when the flowers are ready to harvest to the consumers.  The handling of post-harvest chrysanthemums is an important factor that is inseparable from the stages of cultivation and greatly influences the selling value and added value that will be obtained by farmers and traders. The use of pulsing and holding liquid during display will extend the chrysanthemum vase life. By implementing post-harvest chrysanthemums in accordance with handling procedures (SOP), chrysanthemums will be obtained that can meet quality standards and can provide added value for farmers and flower traders

This investigation was carried out to study the effect of 100, 200 and 300 ppm 8-hydroxyquinoline sulphate (8-HQS) and 5 and 10% sucrose treatments on the vase life and post-harvest quality of cut flowers of Strelitzia reginae Ait. and Hippeastrum vittatum Herb. cv. Apple Blossome. All possible combinations of 8-HQS and sucrose were tested. The treatments were applied as holding solutions, and control flowers were held in distilled water till the end of the experiment. All the treatments significantly increased the vase life and number of open florets of Strelitzia reginae cut flowers compared to the control. Applying 8-HQS and sucrose treatments in both seasons improved the vase life and floret longevity of Hippeastrum vittatum cut flowers. In addition, the percentage of fresh weight gain from the initial weight and the carbohydrate content were also enhanced in both cut flower crops. In order to obtain the highest post-harvest quality of Strelitzia reginae Ait. and Hippeastrum vittatum Herb. cv. Apple Blossome cut flowers, treatment with 200 ppm 8-HQS + 10% sucrose was recommended.

Abstract Capitulum wilting and neck bending are the two important complications that impair the post-harvest quality and vase life of the gerbera cut flowers. The present study investigates the effects of pre- and post-harvest treatments of spermine (SPER), γ-aminobutyric acid (GABA) and β-aminobutyric acid (BABA) on the vase life, qualitative features and enzyme activity of gerbera cut flowers ‘Stanza’. The pre-harvest treatments (1 mM doses) were applied by foliar spraying, and the post-harvest were by pulse treatment (5 mM doses). The flowers kept their quality longer in pre and post SPER and GABA treatments. The longest vase life was recorded in pre-SPER (14 days) and pre-GABA (13 days) compared to BABA treatments and controls (9 days). Neck bending was observed more frequently in controls whereas SPER and GABA showed a lower neck bending rate at 9 days after harvest. The highest vase solution uptake, total soluble solids, total flavonoid, total protein, the activities of catalase, peroxidase, superoxide dismutase, phenylalanine ammonia-lyase, and ascorbate peroxidase, besides the lowest neck bending, electrolyte leakage, malondialdehyde, H2O2 and polyphenol oxidase activity were observed in pre-SPER treatment and subsequently in pre-GABA. Pre- and post-harvest treatments with β-Aminobutyric acid (BABA) had no significant effects on cut flowers compared to SPER and GABA, although showed slightly better effects than water control. It is therefore suggested that pre-harvest treatment using SPER and GABA can improve the vase life and quality of gerbera cut flowers.

Abstract Quality of cut flowers is an important issue at postharvest as well as an important factor contributing to marketing of and profitability from the tuberose. In this study, the effects of citric acid (CA) and hydrogen peroxide (H2O2) added to the vase water on postharvest quality of tuberose cut flowers were investigated. CA was applied in concentrations of 50, 100, 200, 400 mg·dm−3 and H2O2 in concentrations of 10, 20, 40 and 80 mg·dm−3 and distilled water as control treatment. Results showed that both compounds had significant positive effects on solution uptake, wilting and abscission of florets, relative water content, chlorophyll content, and vase life duration. The effects of 100 and 200 mg·dm−3 of CA and 20 and 40 mg·dm−3 of H2O2 proved to be more effective than other treatments. Both compounds increased the vase life of tuberose cut flowers and CA at concentrations 100 and 200 mg dm−3 and H2O2 at concentrations 20 and 40 mg dm−3 doubled this time up to 14-17 days.

Floral exchange markets drive steadily growing interest in ornamental plants sold as cut flowers. Unfortunately, vase life of some of these flowers remains unsatisfactory. Their ornamental value depends on their longevity and number of flowers, as well as overall appearance of the stem during its vase life. Our study determined the effects of storage conditions and Floralife flower food on vase life and ornamental value of Crocosmia ×crocosmiiflora ‘Lucifer’. Crocosmia inflorescences can be attractive cut flowers after meeting some basic requirements. Cutting the branched shoots when the first flower in the main inflorescence was fully open, the second was opening and the subsequent buds showed visible color allowed for maintaining their decorative value for an average of 18.8 days, irrespective of storage conditions and flower food. Vase life and ornamental value depend on storage conditions. Keeping the inflorescences in a semi-lit room (16.8 µmol∙m–2∙s–1), at 18–20°C, and relative humidity of 55–60% or in darkness, at 14–16°C, and relative humidity of 60–70% reduced the number of developed flowers, inflorescence weight and the amount of absorbed solution, and also declined inflorescence vase life. Application of Floralife 200 and Floralife 300 flower food increases the vase life by respectively 7.9 and 8.2 days vs. water, and improves the quality of stored inflorescences.
