in order to examine the effects of essential oils and silver nanoparticles as anantimicrobial preservative in the solutions of alstroemeri cv. sukari cut flowers, anexperiment was conducted with 11 treatments and 3 replications in a completelyrandomized design. in this study, we used essences of carvacrol, thymol and zataria oilwithconcentrations of 50 and 100 mg l-1 and silver nanoparticles wi...
leaf yellowing is a major problem in postharvest of alstroemeria cut flowers. for delaying of leaf yellowing and increasing flower quality a completely randomized factorial design was carried out on the alstroemeria cut flowers (‘fuji’ cultivar). in this research ethanol (0, 2, 4, 6%), ga3 (0, 50, 100, 150 mg/litre) in two methods (pulse and continuous) were investigated on the flower vese life...
Postharvest improvement of water relations and water uptake of cut flowers and control of microbial contamination of preservative solutions is one of the most important strategies in maintaining postharvest quality and prolonging of cut flowers vase life; especially for leafy flowering stems such as alstroemeria. This experiment was conducted to evaluate the effects of different peppermint’s es...
Leaf yellowing or petal senescence is the main postharvest disorder for many cut flowers. Plant hormones such as cytokinins are able to inhibit leaf yellowing in some cut flowers and potted plants. In our experiments, we applied thidiazuron aiming to delay leaf yellowing and 1-methylciclopropene (1-MCP) for inhibiting flower senescence of cut stock flowers during vase life. Cut flowers were pul...
Premature leaf yellowing of Alstroemeria cut flowers prior to petal fall is the most important limiting factor of the flower postharvest life. In this study, cut flower Alstroemeria cv. Bridal were treated for 24 hours with different solutions including gibberllic acid, benzyl adenine, natural essential oil carvacrol with two concentrations of 50 and 100 mg L-1, 5-sulfo salicylic acid in two co...
Alstroemeria is one of the most beautiful cut flowers in the world that has allocated major part of cut flowers exports to itself. One of the main problems in the trade this flowers is a premature yellowing of the foliage. Therefore, the present study was designed to investigate increasing the vase life and delay of leaf yellowing Alstroemeria cut flowers cultivar "Fortaleza". The experiment wa...
Dendranthema grandiflorum L. is one of the widely cultivated flowers around the world for producing of cut flowers. Nanometer-sized silver particles are used in various applications as an anti-microbial compound. This experiment was carried out to study the effects of silver nanoparticles (0, 5, 10 and 20 mg/L) and sodium silicate (0, 50, 100 and 150 mg/L) on longevity and quality of cut chrysa...
the aim of this research was to improve quality and vase life of cut gladiolus flowers. the investigation was done with the effects of different concentrations of essential oil of thymol and zataria oil (50 and 100 mg l-1) and silver nanoparticles (3 and 5 mg l-1) and 8-hydroxyquinolin sulfate (300 and 400 mg l-1) with sucrose 3%. in addition, distilled water, ethanol 500 mgl-1 and sucrose 3% w...
