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.

Duration Of Storage

Narcissus, belonging to Amaryllidaceae family, is one of the emerging cut flower in ornamental industry. Appropriate cut flower packaging for ideal time period provides potential benefit of improving their post-harvest quality of flower. Current research was conducted with an objective to find out best suitable packaging materials and optimum storage duration for cut flowers of narcissus. Narcissus postharvest features were analyzed statistically and results showed significant difference among the treatments with respect to packaging material as well as storage duration. In our findings, polyethylene sleeve showed best results in most of postharvest parameters (vase life, total life, dry weight, and change in fresh weight). In our results, 2 hours duration of storage significantly improved the post-harvest parameters of cut Narcissus. Vase life, fresh and dry weight of flower obtained maximum value in two hours storage duration. It was interesting to note that as storage duration increased, post-harvest characters reduced. In conclusion, postharvest quality of cut Narcissus can be improved significantly by using suitable packaging material and optimizing storage duration.

Ethylene Inhibitor

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.

<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.

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.
