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.

Cut flowers of Dianthus caryophyllus L. cv. Asso were treated with 8-hydroxyquinoline sulphate (8-HQS) at 200 and 400 ppm with or without sucrose at 50 g l-1, silver thiosulphate (STS) at 0.2 and 0.4 mM with or without sucrose at 50 g l-1,and 1-methylcyclopropene (1-MCP) at 0.3, 0.5 and 0.7 g m-3 for 6 h to study the effect of these chemicals on post-harvest quality. 8-HQS treatments increased the vase life and the percentage loss of initial fresh weight compared to the control. In addition, the vase life was longer when sucrose was applied in combination with 8-HQS. The best treatment involved 400 ppm 8-HQS + 50 g l-1 sucrose. All the concentrations of STS prolonged the vase life and fresh mass compared to the control. The best treatment was STS at 0.4 mM with or without sucrose. All levels of 1-MCP prolonged the vase life and increased the fresh weight in comparison with the control. The best treatment in this respect was 1-MCP at 0.5 g m-3 for 6 h. The chlorophyll content (chl a and chl b) in the leaves was higher than the control in the best treatment of each chemical.

The Impact

Tuberose (Polianthes tuberosa L.) is an ornamental bulbous plant and a famous cut flower in tropical and subtropical regions. Post-harvest senescence of the cut flowers is the main factor limiting the marketability of most of these species including tuberose. From the perspective of metabolic changes, senescence happens as the result of oxidative processes induced by active oxygen species production. Gamma-aminobutyric acid (GABA) and salicylic acid (SA) are compounds with some functions in the post-harvest physiology of some plants. The present study focused on the effect of GABA and SA on vase life and some post-harvest traits of cut tuberose flowers. The plants were sprayed with GABA (5, 10, or 15 mg L–1) and SA (50, 100, or 150 mg L–1) at three stages during growth and before harvest in a greenhouse (30, 45, and 60 days after the planting of the bulbs) and were observed after harvest until senescence. Results showed that GABA and SA positively affected the vase life, water uptake, fresh weight, ion leakage, total dissolved solids, chlorophyll, protein, and catalase, peroxidase, and ascorbate peroxidase enzymatic activity. They postponed senescence. The highest and lowest vase lives were observed in plants treated with 10 mg L–1 GABA (11 days) and control (distilled water) (7 days), respectively. It was found that the treatment of tuberose with GABA and SA during growth can improve its post-harvest quality. However, it is recommended to conduct further studies on them.

Background: The use of wrapping material during storage of cut flowers creates a modified atmosphere which reduces flower metabolism during storage, thereby slowing carbohydrate consumption as respiratory substrate. The main problem related to dry storage is moisture loss or desiccation. Keeping in view the above aspects, the present study was conducted to enhance the shelf life of tuberose.Methods: The experiment was carried out at Post-Harvest Laboratory of Department of Horticulture, COA, CCS HAU, Hisar during the cropping season (March to September) of year 2019. It was laid out in CRD (factorial) with three replications and twenty-four treatment combinations, comprising of six wrapping materials (newspaper, butter paper, chart sheet, low density polyethylene of 100µ, high density polyethylene of 200µ and control as without wrapping) and four storage time (1, 4, 7 and 10 days), were tested. After harvesting, cut spikes were wrapped in wrapping materials and kept in cold-store at low temperature (less than 5°C), thereafter cut spikes were placed in vase solution (4% sucrose plus 300 ppm 8-HQC) for recording observations on floral parameters. Result: Among different wrapping materials, the butter paper wrapped cut spikes observed better in most of the parameters followed by LDPE (100µ) wrapped cut spikes. Among the storage time, storage of cut spikes for 1 day observed better in most of the parameters except time taken up to opening of first pair of florets and total post-harvest life. Overall, butter paper wrapped cut spikes stored for 1 day performed better in term of floret diameter (46.73 mm), floret length (56.10 mm), floret longevity (2.89 days), appearance (3.70/5.0 scale), florets opened at a time (32.30%), total opened florets (54.32%), marketable vase life (6.53 days), total vase life (11.17 days), weight loss (17.08%) and solution consumed (135.33 ml) by the spikes. However, the cut spikes wrapped in butter paper stored for 10 days were found better with early opening of first pair of florets (0.95 days) and maximum post-harvest life (20.10 days).

Lupinus havardii (Big Bend bluebonnet) is native to a narrow geographical range along the Rio Grande River in southwest Texas and produces attractive blue flower spikes which have potential as cut flowers. Without any post-harvest treatments, these spikes had an average vaselife in water of about 7 d. During this period, an average of about 13 florets were abscised per spike. When preconditioned for 4 h in 40-80 mg/liter silver thiosulfate (STS), vaselife increased to 11 days and only 1-3 florets were abscised per spike. Post-harvest treatment of the spikes with 25-50 mg/liter oxime ether, a new ethylene inhibitor, surprisingly enhanced floret abscission and shortened vaselife. The basis for this response is not clear. Storage of STS-preconditioned spikes in water at 5C for 72 h only decreased vaselife by about one day compared to unstored controls. Dry post-harvest storage at 5C for 72 h caused severe wilting, but upon rehydration these spikes still had a vase/life of about 8 d. These results indicate mat cut flower spikes of L. havardii have good post-harvest qualities and can be stored for up to 3d without seriously limiting vaselife.
