<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".

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.

<p>ABSTRACT</p><p>The freshness of  Zingiber  spectabile  Griff Silvana (bihip) as cut flowers must be maintained by the appropriate  post-harvest treatment. One of the post-harvest technologies that is commonly used is the use of chemical 1-Methylcyclopropene (1-MCP). This study was aimed to extend the vase life of bihip flowers using 1-MCP to gain optimum concentration of 1-MCP that can extend the vase life of bihip flowers, and to find the best application technique of 1-MCP  for longest vase life of bihip flowers. This study used a completely randomized design (CRD) factorial with two factors. The first factor was the concentration of 1-MCP that consists of five levels; 0 ppm (A0), 0.001 ppm (A1), 0.002 ppm (A2), 0.003 ppm (A3), and 0.004 ppm (A4). The second factor was  application technique of 1-MCP : sprayed (B1) and soaked (B2). The results showed that 1-MCP significantly extended the vase life of cut flowers bihip flowers up to 11.30 day compared to control which  was  only 9.55 day. Concentration 0.004 ppm of 1-MCP was able to extend optimum vase life of cut flowers bihip until 11.30  day.  Method  of  1-MCP  application  to efficiently  extend  bihip  flowers  until  11.10  day  was soaking in a solution of 1-MCP. The combination treatment of 1-MCP to extend the vase life of bihip flowers was 1-MCP treatment concentration of 0.004 ppm and soaking treatment. Treatment with 1-MCP at 0.004 ppm extended bihip flowers vase life.</p><p>Key words: 1-Methylcyclopropene, bihip flowers, vase life, Zingiber spectabile Griff.

The quality of seed needs to be considered in carrot seed production to maintain its productivity. The research aims to find out the response of stecklings age and plant spacing on carrot seed quality and production. This research was held on July 2018 – April 2019 in Berastagi field trial (1340 m MSL). The experiment used Randomized Complete Block Design (RCBD) with two factors, i.e., stecklings age (2 and 3 months) and plant spacing (25, 50, 75, and 100 cm), replicated four times (32 experiment units), 10 plants from each experiment units were taken as samples. The result showed that stecklings age and plant spacing were affected to plant vegetative and generative stages. The combination of 2-month stecklings and 50 cm plant spacing increased the number of secondary umble, if compared to cultivation, which was generally used by the farmer (3-month stecklings and 25 cm plant spacing). The best quality of carrot seed was obtained from the combination of 3-month stecklings and 50 cm plant spacing.

The cut flowers are living organs, with intense metabolic activity, subjected to a rapid aging process compared to the undetached flowers from the mother plant. Improving the life of cut flowers is one of the most important factors for customer satisfaction. The effect of silver thiosulphate (STS) and commercial mixtures was studied in carnation cut flowers and kept in randomized vases according to experimental factors. Three commercial mixtures were used (Chrysal, Flower Food, Fleur̛ Rose) and for thiosulphate four levels (0 or control, 0.03, 0.06 and 0.9 mM). The interaction of the two factors studied was insignificant for most traits, including wilting percentage and vase lifespan, which may involve the application of both substances alone is sufficient to improve post-harvest quality and is not necessary to use simultaneously in the preservative solution. The results also showed that following the interaction of the two factors, treatment with 0.06 mM silver thiosulphate can be applied to improve the post-harvest quality of blossom cut flowers and commercial chemical mixtures can be successfully replaced.

Stem Bending

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 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.

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

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.

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.
