The respiration of cut flowers of gerbera (Gerbera jamesonii H. Bolus ex Hook.f. `Vesuvio') and sunflower (Helianthus annuus L.) increased exponentially with increasing storage temperature. Poststorage vase life and negatively gravitropic bending of the neck of the flowers were both strongly affected by simulated transport at higher temperatures. Vase life and stem bending after dry storage showed highly significant linear relationships (negative and positive, respectively) with the rate of respiration during storage. The data indicate the importance of maintaining temperatures close to the freezing point during commercial handling and transport of these important commercial cut-flower crops for maximum vase life.

The postharvest longevity of fresh-cut flowers is often limited by the accumulation of bacteria in vase water and flower stems. Aqueous chlorine dioxide is a strong biocide with potential application for sanitizing cut flower solutions. We evaluated the potential of chlorine dioxide to prevent the build-up of bacteria in vase water and extend the longevity of cut Matthiola incana `Ruby Red', Gypsophila paniculata `Crystal' and Gerbera jamesonii `Monarch' flowers. Fresh-cut flower stems were placed into sterile vases containing deionized water and either 0.0 or 2 μL·L–1 chlorine dioxide. Flower vase life was then judged at 21 ± 0.5 °C and 40% to 60% relative humidity. Inclusion of 2 μL·L–1 chlorine dioxide in vase water extended the longevity of Matthiola, Gypsophila and Gerbera flowers by 2.2, 3.5, and 3.4 days, respectively, relative to control flowers (i.e., 0 μL·L–1). Treatment with 2 μL·L–1 chlorine dioxide reduced the build-up of aerobic bacteria in vase water for 6 to 9 days of vase life. For example, addition of 2 μL·L–1 chlorine dioxide to Gerbera vase water reduced the number of bacteria that grew by 2.4- to 2.8-fold, as compared to control flower water. These results confirm the practical value of chlorine dioxide treatments to reduce the accumulation of bacteria in vase water and extend the display life of cut flowers.

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.

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.

Postharvest studies were carried out in three varieties of (Gerbera jamesonii Hook.) cvs. Primrose, Malibu and Sunway to find out the effect of growing seasons (autumn, winter and spring) on the vase life of cut flowers during September 2009 to March 2010. Laboratory experiments were carried out in controlled room having 18±2°C temperature, 68±2% relative humidity and 100 lux light. The study revealed that the longest vase life was noticed in Sunway, followed by Primrose and Malibu. Regarding the season of production, longest vase life (18.37 days) was found in the flowers harvested in winter, followed by spring (14.8 days) and autumn (9.57 days). The interaction effect of season and variety showed that longest vase life (23.2 days) was found in Sunway harvested in winter whereas the shorter vase lives (5.7 and 7.8 days) were in Malibu and Primrose respectively harvested in autumn. Stalk length (57.88 cm) and floral diameter (10.78 cm) were highest in autumn while diameter of the stalk (0.64 cm) was the highest in spring. Sunway had the highest floral and stalk diameters, while the stalk length was longer in Malibu and Primrose. Total water uptake during the vase life was highest in flowers grown in winter (34.9 ml), followed by spring (34.7 ml) and autumn (26.14 ml).

Rose cut flower is one of the widely grown cut flowers in Kenya. However, most roses have a challenge of short vase life. This study aimed at determining the efficacy of plant extracts from thyme and stevia in preservation of rose cut-flowers. Two rose cut-flower cultivars; ‘radiance and ‘high & sparkling’ were subjected to stevia and thyme extracts each at three levels (0.2, 0.4, and 0.6gL-1). Thyme extracts at a concentration of 0.2 gL-1 significantly (p≤001) extended the vase life of rose cut flower by 3.5 days and floral absorption rates by 10.4% compared to the commercial preservative (chrysal) at the same concentration rates. Application of higher doses (0.4gL-1 and 0.6gL-1) of plant extracts led to shorter vase life (6 days) of rose cut flower and maximum bent neck records at day 8. The response of rose cut flower to the treatments did not vary between cultivars. The results from this study indicate that thyme extracts offer an attractive alternative to the use of chemical floral preservatives for prolonging the vase life and enhancing quality of rose cut flower. The efficacy of extracts is however depended on the concentration level with 0.2gL-1 dosage recording the best results.

Snapdragon (Antirrhinum majus L. `Chitchat'), delphinium (Delphinium ajacis L. `Bellisimo'), chrysanthemum (Dendranthema grandiflora RAM. `Regan'), tulip (Tulipa hybrid `Golden Brush'), gerbera (Gerbera jamesonii H. Bolus `Manovale'), oriental lily (Lilium asiaticum L. `Specisiom Simplon'), rose (Rosa hybrid L. `Carnavale') and iris (Iris hollandica Tub. `Blue Magic') cut flower stems were placed at 20 °C in water containing the NO donor compound 2,2'-(hydroxynitrosohydrazino)-bisethanamine (DETA/NO) at 10 and 100 mg·L-1 and after 24 h, transferred to humidified air containing 0.1 μL·L-1 ethylene. Compared with flowers kept in water, the vase life of all eight flowers was extended by DETA/NO with an average extension of about 60% with the range being about 200% for gerbera to 10% for chrysanthemum. DETA/NO appears to have widespread applicability to cut flowers and offers a simple technology to extend vase life.

Iris hollandica `Blue Magic' was treated with deionazed water as a control, 3% sucrose (Suc), 3% sucrose plus 0.4 mm silver thiosulphate (Suc+STS), 3% sucrose plus 200 mg·L-1 8-hydroxyquinoline sulphate (Suc+HQS) and 3% sucrose plus 100 mg·L-1 benzyl amino-purine (Suc+BA) for 4hrs and then transferred to tap water. The vase life treated with Suc+BA was extended 4 days longer than that of control. The treatment Suc+STS or Suc+HQS did not improve vase life. The amounts of water uptake and transpiration by all treatments decreased after harvest, but those values were higher in cut iris treated with Suc+BA than in those with control. Cut flowers treated with by Suc+BA markedly improved water balance, comparing with control which was quickly changed to minus value. Anthocyanin content in petals of cut flower treated with Suc+BA was 3.5 fold higher than that of control. The treatment by Suc+BA delayed discoloration in petals and senescence of cut Iris. Peroxidase (POD) activities of all treatments were reached maximum at 4th day after treatment and decreased thereafter. POD activity was highest when the cut iris was treated with Suc+BA. These results show that the use of Suc+BA is most effective treatment for improving the vase life and quality of cut Iris flowers.

<p>ABSTRACT<br />Heliconia ‘Sexy Pink’ has beautiful bright pink colour and big size of bractea. The quality of Heliconia ‘Sexy Pink’ as tropical cut flower can be maintained with appropriate post-harvest treatments. One of the post-harvest technology that can be applied is the use of disinfectant and 1- Methylcyclopropene (1-MCP). The objective of the study was to prolong the vase life of Heliconia ‘Sexy Pink’ using disinfectant and 1-MCP, and to determine the optimum concentration of disinfectant (active compound: sodium hyphoclorite-NaClO) and 1-MCP applied separately or in combination. This study used factorial randomized complete block design with two factors and ten replications. The first factor was concentration of disinfectant (NaClO) i.e 0% (A0), 0.5% (A1), 1.0% (A2) and 1.5% (A3). The second factor was 1-MCP i.e 0 ppm (B0), 0.003 ppm (B1), 0.004 ppm (B2) and 0.005 ppm (B3). The results showed that optimum 1-MCP concentration for maintaining the vase life of Heliconia 'Sexy Pink' cut flowers by 30% from total amount of bractea blackened variables was 0.005 ppm; This 1-MCP concentration kept the vase life for 6.2 days. Vase life of Heliconia 'Sexy Pink' cut flower with the combination treatment without disinfectant and 1-MCP concentration of 0-0.005 ppm based on hedonic test by panelists still preferably up to 8 days. Hedonic test criteria is recommended to indicate the vase life of Heliconia 'Sexy Pink' cut flower. The addition of the disinfectant is not advisable to maintain the vase life of Heliconia 'Sexy Pink' cut flower.<br />Key words: 1-methylcylopropen, Heliconia, NaClO, tropical cut flower, vase life</p><p>ABSTRAK<br />Heliconia "Sexy Pink" memiliki warna merah muda yang indah dengan ukuran besar dan rangkaian braktea cukup banyak. Kualitas bunga Heliconia "Sexy Pink" sebagai bunga potong tropis dapat dipertahankan kesegarannya dengan perlakuan aplikasi pascapanen yang tepat. Salah satu teknologi pasca panen yang dapat digunakan ialah aplikasi bahan kimia berupa disinfektan dan 1- Methylcyclopropene (1-MCP). Penelitian ini bertujuan mempertahankan vase life bunga potong Heliconia "Sexy Pink" menggunakan disinfektan (bahan aktif: sodium hipoklorit-NaClO) dan 1- MCP. Penelitian ini mengggunakan rancangan kelompok lengkap teracak (RKLT) faktorial dengan dua faktor. Faktor pertama adalah konsentrasi disinfektan (NaClO): 0% (A0), 0.5% (A1), 1.0% (A2) dan 1.5% (A3). Faktor kedua yaitu konsentrasi 1-MCP: 0 ppm (B0), 0.003 ppm (B1), 0.004 ppm (B2) dan 0.005 ppm (B3), sehingga terdapat 16 kombinasi perlakuan yang diulang 10 kali. Setiap satuan percobaan terdiri atas 1 tangkai bunga, sehingga terdapat 160 tangkai bunga Heliconia "Sexy Pink". Hasil penelitian menunjukkan bahwa konsentrasi 1-MCP yang optimum untuk mempertahankan vase life bunga potong Heliconia "Sexy Pink" berdasarkan peubah 30% braktea menghitam adalah 0.005 ppm; konsentrasi ini dapat memperpanjang masa segar bunga selama 6.20 hari. Vase life bunga potong Heliconia "Sexy Pink" dengan kombinasi perlakukan tanpa disinfektan dan konsentrasi 1-MCP 0-0.005 ppm berdasarkan uji hedonik masih disukai panelis hingga 8 hari. Kriteria uji hedonik lebih direkomendasikan untuk menunjukkan vase life bunga potong Heliconia "Sexy Pink". Penambahan disinfektan tidak disarankan untuk mempertahankan vase life bunga potong Heliconia "Sexy Pink".<br />Kata kunci: 1-methylcylopropene, bunga tropis, Heliconia, NaClO, vase life</p>
