Enhancing the vase life of cut foliages is one of the prime goals of floriculturist and it is very interesting and important aspect of floriculture.The efforts were made to find out best waxing treatment for enhancing the vase life along with excellent quality maintenance for few cut foliage species .The objective was to evaluate optimum percent wax solution for improving post harvest life and quality of ornamental plants. Different wax emulsion treatments (0.25, 0.50, 0.75 and 1.00 %) showed significant results in both quantitative and qualitative attributes of ornamental species. In Asparagus densiflorus ‘Sprengeri’ and Eucalyptus teritecornis,0.75% wax emulsion concentration recorded minimum foliage weight (5.62, 20.49 g) and minimum water uptake (5.60, 32.73 ml) respectively on 3rd day, while maximum foliage weight (0.90, 6.84 g) and maximum water uptake (1.13, 13.77 ml) was recorded on senescence day. In Caryota urens (Fishtail palm) 0.50% wax emulsion concentration recorded minimum foliage weight (9.71 g), minimum water uptake (6.53 ml) on 3rdday, while maximum foliage weight(1.83 g) and maximum water uptake (1.20 ml) on senescence day. In Heliconia psittachroum cv. Golden Torch, 1.00 % wax emulsion concentration recorded minimum foliage weight (28.85 g), minimum water uptake (20.35 ml) on 3rdday, whereas maximum foliage weight (15.83 g)and maximum water uptake (5.75 ml) on senescence day. There was improvement and increament in post harvest quality and vase life of studied ornamental cut foliages.

The study was conducted to determine the effect of pre harvest spray of micronutrients like boron, zinc and its combination on post harvest quality and vase life of carnation. Post harvest quality of flowers like flower stalk length (65.61 cm) was maximum in the plant treated with zinc (0.3 per cent), and calyx splitting (3.12 per cent) was minimum in the plants treated with boron (0.1 per cent). Flower diameter (6.64 cm) was highest with boron (0.1 per cent) + zinc (0.3 per cent) treatment. Plants without micronutrient treatment produced poor quality flowers. Regarding vase life studies maximum water uptake and minimum transpiration loss from first day to sixteenth day was resulted in the flowers which are obtained from the plant treated with boron (0.1 per cent). The maximum fresh weight of the flower was noticed in combination of boron (0.1 per cent) + zinc (0.3 per cent) from first to sixteenth day. The foliar spray of boron (0.1 per cent) recorded maximum vase life (11.05 days). So the good quality of flowers can be improved by the foliar spray of zinc, calyx splitting can be controlled by boron foliar spray and vase life of the flower can be maintained by foliar spray of boron. It is confirmed that the foliar application of micronutrient is very much helpful for the improvement of post harvest quality and vase life of carnation.

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.

Abstract Phyto-hormones play a key role in regulating plant responses to stress. Cytokines are a type of phyto-hormones involved in the regulation of many important biological processes related to growth, development, and response to environmental variables. The exogenous application of cytokines increases the possibility of delaying senescence; however, this is a physiological process, and, under certain conditions, degradation processes may be triggered. The effect of 6-bencilaminopurine application and the endogenous hormonal changes involved in lilies floral stalks after their cutting were studied. In order to improve vase life and quality of Lilium longiflorum ‘Brindisi’ flower stalks, they were sprayed with 6-BAP, at a concentration of 300 ppm at pre-harvest, post-harvest, and pre- and post-harvest stages. After that, they were compared to non-sprayed control stalks. The application of 6-BAP caused endogenous hormonal changes in abscisic acid and cytokinin levels, and the most effective treatment was pre-harvest spraying. This treatment proved to be an appropriate method to improve the stalk tolerance to post-harvest stress as it delayed the appearance of senescence symptoms and reduced the speed of chlorophyll degradation with differences of up to 10% with respect to untreated stalks. In addition, the opening of flowers was delayed by up to 2 days, although there were no significant differences in total vase life.

<p>Several experiments reveal that distilled water varies among different laboratories and also does not have a standard composition. Water electrical conductivity (EC) of vase solution is one of the parameters that influence the water uptake by cut flowers. Therefore, the objective of this work was to evaluate the influence of electrical conductivity on water uptake and vase life in cut stems of gladiolus. The stems harvested and kept in distilled water (pH 6.6, EC &lt;0.01dS m-1) and tap water (pH 7.0, EC 0.75 dS m-1) at room temperature. Flowers kept in tap water showed lower fresh weight loss after the second day and higher water uptake during vase life. In a second set of experiments, we verified the limit EC saturation supported by the flower. For this, flowers were placed in individual test tubes containing four different solutions with varying ion concentrations. Solution 2 (EC 0.60 dS m-1) promoted increased vase life and allowed maximum water uptake by the flowers. The results show that the electrical conductivity of vase solution is a major parameter in experiments with vase life of cut gladiolus. The presence of ions in the vase solution increases the overall vase life and improves water uptake of flowers with favorable optimal EC between 0.60 to 0.87 dS m-1.</p>

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

Cultivation Site

Due to the dynamic development of the floriculture market, new species and varieties of plants that can potentially be used as a source of cut greenery are constantly being sought. The experiment was conducted to analyze the effect of the cultivation site (unheated foil tunnel and open field) and treatments with the Pentakeep V formulation (0.00%, 0.02%, 0.04%, and 0.06%) on the vase life and postharvest quality of Polygonatum multiflorum ‘Variegatum’ cut foliage. There was a positive effect of the cultivation in the unheated foil tunnel on the vase life and biochemical parameters, namely the electrolyte leakage (EL), thiobarbituric acid reactive substances (TBARS), chlorophyll a + b (Chl. a + b), proline, peroxidase (POD), and ascorbate peroxidase (APX), of P. multiflorum cut foliage. Foliar application of Pentakeep V formulation at concentrations of 0.04% and 0.06% contributed to a decrease in the TBARS content in the P. multiflorum cut leaves, regardless of the plant cultivation site. Additionally, it reduced proline production in cut leaves of P. multiflorum cultivated in the unheated foil tunnel, which was confirmed by the analyses carried out after the 30 days of the experiment. Furthermore, the exogenous application of ALA during P. multiflorum cultivation inhibited POD activity, irrespective of its concentration and the site of plant cultivation.

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.
