Was schildern Andere, die Behandlungen mit Alstroemeria gemacht haben? Keeping quality and length of vase life are important factors for evaluation of cut flowers quality, for both domestic and export markets. This research attempts to test the hypothesis that sugars may extend the vase life of spray carnation by suppressing ethylene biosynthesis, more specifically suppressing ACC production or ACO activity or both. Also, the results showed that the using salicylic acid increased significantly the vase life cut alstroemeria flowers, over control. In this study, the effect of nanosilver (NS) on certain aspects of senescence in cut garden cosmos (Cosmos bipinnatus) flowers was compared to that of the commonly used 8-hydroxyquinoline citrate (8-HQC). Most of these parameters were not significantly correlated with vase life. In colder areas, they add color when used as a container or indoor plant. Flowers treated with 1.5 (continuous exposure) and 15 mM (pulse) SA showed a significant decrease in weight loss, and antioxidant activity increased, compared to the control solution, but the flowers in the control solution indicated an increase in weight loss. This result was due to the activation of, the cells through proper absorption of nutrient solu-, tion and cell turgor. Rinse them with water and air dry them before beginning to cut.

Both biocides were comparably effective in limiting this effect. Some professional florists suggest adding a drop of bleach to the water in the vase, … It was concluded that treatment of cut alstroemeria flowers with putrescine were effective on keeping quality and can be used commercially to extend the vase life of cut alstroemeria flowers with acceptable quality. Overall, the effect of nanosilver on senescence in cut cosmos flowers was similar to that of 8-HQC. Also, the results showed that the using putrescine treatment increased significantly the vase life cut alstroemeria flowers, over control. and is effective against resistant strains of Pseudomonas aeruginosa, Acinetobacter spp. It begins by outlining the history and science of bacteriology and gives an overview of the diversity and versatility of complex bacteria. The widespread and often indiscriminate use of antibiotics has created drug-resistant Gram-negative bacilli that readily acquire multiple resistance through transmission of drug resistance plasmids (R factors). Studding the effect of pre- and post-harvest salicylic acid applications on keeping quality and vase life of cut alstroemeria flowers during vase period is the approach taken. OD/min: Changes of absorption per unit of time, 0.5 g of leaves and petals from each treatment, 50 ml of distilled water for 24 h at room tem-, perature. the pre-harvest spraying method (B) on the 12th day. Planting the roots too deep can lead to excess moisture along the stem and fugal infection. The experiment was, This study was performed as per a completely, randomized factorial design with 33 treatments in, three replications, and 99 plots. Carotenoids were then measured, Finally, the destruction of the carotenoids content, was calculated by subtracting the concentration of, carotenoid on the last day (the end of vase life). (. The goal of this study was to investigate and compare the effect of pre- and post-harvest putrescine applications on keeping quality and vase life of cut alstroemeria flowers during vase period. Since the stem and the secateurs are not a main source of bacteria inside stems and tap water contains pseudomonads and Enterobacter spp., we conclude that tap water is the main source of the bacteria inside cut rose stems. Alle Alstroemeria im Blick. The cut flowers were harvested in the early morning and both of cut flowers treated (sprayed) and untreated were kept in vase solutions containing salicylic acid at 0.0 (with distilled water), 1, 2 and 3 mM. Join ResearchGate to find the people and research you need to help your work. Pick harlequin bugs, a type of stink beetle, from the leaves to stop their munching. ), Anthurium andraeanum, peonies (Paeonia spp. The increase in vase life, after sugar treatment, has also been associated with suppression of ethylene biosynthesis, in cut flowers such as snapdragon (Ichimura and Hisamatsu, 1999), rose (Liao et al., 2000), and/or reduced sensitivity to ethylene, as in carnation: Mayak and Dilley, 1976) and delphinium (Ichimura et al., 2000). It, typically contains (mass/volume): 0.5% peptone, yeast extract whose- water-soluble contents con-, tribute vitamins, carbohydrates, nitrogen and, proportions similar to those found in the cyto-, plasm of most organisms, distilled water- that, serves as a transport medium for the agar, ious substances and pH adjusted to neutral (6.8), at 25°C. M. Ershad Langroudi, D. Hashemabadihttps://orcid.org/0000-0003-2495-504X, ects of silver nanoparticles, chemical treatments and herbal essential oils, cation of bacteria in the vase solution. In this review, we outline the role of NS particles in the suppression of ethylene production and microbial growth in cut flowers and discuss how the concentration and size of NS particles, incubation time, and plant genotype affect postharvest longevity. The results show that pre- and postharvest SA application prolonged the vase life of cut roses through improving CAT and POD activity, and decreasing lipid peroxidation. In, B.C., Motomura, S., Inamoto, K., Doi, M., & Mori, G. vest environmental factors, postharvest morphological, and physiological factors and vase life of cut asomi red, Kandil, M.M., El-Saady, M.B., Mona, H.M., Afaf, M.H., &. Sucrose at 4% was added to all treatments as a base solution. In the second trial, continuous exposure to (0, 0.5, 1.0 and 1.5 mM), and pulses of (0, 5, 10 and 15 mM), SA significantly extended the vase life. Finally, the activity of peroxidase (POD) was expressed in, Methods: spraying preharvest (B), Pulsing 24 h (A, In the Pulse method, each of the vase solutions contained sucrose 20% in addition to the mentioned compounds, and for the. Robust und passt in die meisten Standard-Grab-Vasen. Liu, J., He, S., Zhang, Z., Cao, J., Lv, P., He, S., . It is concluded that sucrose apparently inhibits climacteric ethylene production by inhibiting ACO activity. The most ideal condition of the traits was found for those flowers that were treated with 10 mg l⁻¹ of Nano-silver prior to harvest. Hier findest du eine Selektion von Alstroemeria getestet und währenddessen die relevantesten Fakten herausgesucht. Thus, they play different roles in intra- and extra-cellular signaling. In addition, we highlight recent results on the application of biologically synthesized NS particles in packaging and postharvest management within the horticultural industry. Cutting the stems with sterile secateurs introduced no bacteria at the cut surface or the stem interior, but cutting with nonsterile secateurs used by rose growers did. The aim of this study was to investigate the effects of some chemical compounds on the post-harvest life of alstroemeria cut flowers. The postharvest longevity and quality of cut flowers are affected by floral senescence and petal abscission, which primarily result from both ethylene production in the floral organs (such as the petals and gynoecium) and microbial growth in the xylem vessels in ethylene-sensitive flowers, while microbial growth plays a more crucial role in ethylene-insensitive flowers.
