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.

And Control

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.

Flower Abscission

Big Bend bluebonnet (Lupinus havardii Wats.) is native to a narrow geographic range in southwestern Texas and produces attractive blue inflorescences (racemes) that may be used as cut flowers. Several crops were produced in the greenhouse to determine postharvest-characteristics of the cut inflorescences. Without any postharvest conditioning treatments, the inflorescences held in water had an average vase life of about 7 days. During this period, an average of 13 flowers abscised per inflorescence. When preconditioned for 4 hours in 40 to 160 mg·liter−1 silver thiosulfate (STS), vase life increased to 10 to 12 days and fewer than three flowers abscised per inflorescence. A commercial floral preservative (Oasis) had no effect on flower abscission or vase life of STS-treated inflorescences. Flower abscission and vase life were the same whether STS-treated inflorescences were placed in floral foam moistened with water or in water alone. Storing STS-preconditioned inflorescences in water at 5C for 72 hours did not affect flower abscission or vase life compared to the unstored control. Dry postharvest storage at 5C for 72 hours caused noticeable wilting, but, on dehydration, these inflorescences still had a vase life of about 8 days. Postharvest characteristics of pink-and white-flowered breeding lines were the same as for the blue-flowered line. These results indicate that cut inflorescences of L. havardii have desirable postharvest qualities and can be stored for up to 72 hours without seriously limiting vase life.

Physostegia purpurea Blake is a native, herbaceous perennial that has potential as a field-grown cut flower. Physostegia stems were harvested with one third of the florets open and were recut underwater in the laboratory. Fresh cut flowers treated with silver thiosulfate (STS) and held in a 2% preservative solution lasted 14 days, while control stems in deionized water (DI) lasted 6 days. Cut stems placed in darkness at 0C for 1 week had 8 days of vase life after removal from storage and treatment with STS and preservative, while stems held in DI after storage lasted only 4 days. Stems held dry at 22.5C and 43% RH for 8 hours before being placed in preservative had similar vase life as flowers placed in preservative immediately after harvest.

<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>

During the vase life of cut stems obstruction of xylem vessels occurs due to microbial growth, formation of tyloses, deposition of materials in the lumen of xylem vessels and the presence of air emboli in the vascular system. Such obstructions may restrict water uptake and its transport towards upwards thus lowering their ornamental value and longevity of cut flowers.Clematisis a very attractive plant material which may be used as cut flower in floral compositions. Nothing is known about the histochemical or cytological nature of xylem blockages occurring in cut stems of this plant. This study shows that inclematis, tyloses are the main source of occlusions, although bacteria and some amorphic substances may also appear inside the vessels. A preservative composed of 200 mg dm−38-HQC (8-hydroxyquinolin citrate) and 2% sucrose arrested bacterial development and the growth of tyloses. This information can be helpful in the development of new treatments to improve keeping qualities of cutclematisstems.

Cut flowers of Chrysanthemum morifolium RAM cv. Suny Reagan were treated with different concentrations of 8- hydroxyquinoline sulfate (8-HQS), silver thiosulfate (STS) and 1-methylcyclopropene (1-MCP) in order to improve the post production quality. 8-HQS was used at 200 and 400 ppm with or without sucrose at 50 O. STS was used at 0.2, and 0.4 mM with or without sucrose at 50 g/1 1-MCP was used at 0.3, 0.5 and 0.7 g/m3 for 6h. All the treatments of 8-HQS prolonged the vase life and minimized the percentage of weight loss of chrysanthemum cut flowers compared to the control. The vase life was larger when sucrose not combined with 8-HQS. The best treatment of 8-1-IQS was 400 ppm 8-HQS without sucrose. STS treatment led to prolong the vase life and minimized the percentage of weight loss comparing to the control. In addition, the effect was better when sucroseas was added to STS. The treatment of STS at 0.4 mM + 50 g/I sucrose was the best one. 1-MCP treatment increased the vase life and lowered the percentage of weight loss at any level comparing with untreated control. The best treatment in this concern was 1-MCP at 0.5 g/m3 for 6h. The chlorophyll content (chl.a and chl.b) of the leaves for the best treatment of each chemical was higher than that of the control. The treatment of 1-MCP at 0.5 g/m3 6h gave the best results in this respect.

Number Of Stems

Several cut flower species were studied to determine their feasibility for cut flower production. Three fertilizer treatments (0.5, .1, and .15kg/m2 respectively) were used and their effect on number of stems, stem length and fresh weight were determined. Celosia cristata and Ageratum houstonianum `Blue Horizon' proved to respond best to fertilizer treatments. Celosia fertilized at a rate of .15kg/m2 will produce approximately 200 stems/m2. Ageratum will produce appoximately 400 stems/m2 when fertilized at a rate of .10kg/m2. Fertlizer rates of .10 and .15 kg/m2 for Eustoma culture yielded 86 stems/m2, which was lower than other species used in this test. Extended vase life and consumer response could possibly justify using this species in cut flower production. An economic break-even analysis will be presented to show what price will have to be received per stem to cover costs.

Choice experiments were conducted to explore the market potential or value added when using longevity information and guarantees on cut flower arrangements in the retail setting. The objective of our study was to determine consumer preferences and willingness to pay for different vase life longevities and guarantees on cut flower arrangements. The choice experiment data were collected using online surveys with 525 U.S. consumers in July 2011. The choice experiment scenarios included single species or mixed species cut flower arrangements with varying vase life longevity (5 to 7 days, 8 to 10 days, 11 to 14 days), presence or absence of vase life longevity guarantee, personal or gift use, and price range ($7.99 to $11.99, $34.99 to $43.99). Two types of arrangements were used in the experiment, mixed arrangements consisting of different species of cut flowers and single-species arrangements consisting of six red roses plus a filler flower. We analyzed the data with a mixed logit model and Ward’s linkage cluster analysis. As expected, participants were willing to pay higher prices for cut flower arrangements with longer vase life longevity. The presence of a guarantee improved participants’ probability of selecting the corresponding cut flower arrangement. Using Ward’s linkage cluster analysis, we found there were three distinct consumer clusters: guarantee seekers (49% of the sample), value-conscious consumers (31%), and spenders (20%). Among the three clusters, guarantee seekers were more likely to select cut flower arrangements with guarantees. Value-conscious consumers were interested in both guarantees and longevity indicators. Spenders were least interested in longevity indicators and guarantees. We conclude floral retailers could successfully implement the use of longevity indicators and guarantees to increase consumer interest in cut flowers and generate profits. Target marketing strategies could then be developed by floral retailers to attract different consumer clusters.
