the effect of plant growth regulator short time treatments ( ga3 and tdz) on the increase of vase life and qualitative traits of alstroemeria cultivars ‘odessa’ and ‘sacramento’ were investigated. cut flowers were treated with 24h pulse treatments which included different concentrations of ga3 and tdz. cut flowers were later held in preservative solution (sucrose 2% +nanosid 2ppm) and then thei...

in this study, the concentrations of 25, 375 and 500 ml l -1 of cola+ 2000 mg l -1 of peppermint essence and concentrations of 30, 45 and 60 ml l -1 of apple extract +2000 mg l -1 rosemary essence on alstroemeria cut flowers (cv. balance) were investigated to verify the use of natural ingredients in flowers preservative solutions. this experiment was conducted in the laboratory of gorgan univer...

Alstroemeria is one of the most beautiful flowers in the family Alstroemeriaceae. One of the major problems of this cut flower is short life of leaves, this fact reduces the economic value of this cut flower. Abscission of petal before wilting is also considered as one of the most important problems of this flower. Petals of this flower are very sensitive to ethylene. A factorial experiment bas...

the effects of salicylic acid (sa) and putrescine (put), on cut narcissus was studied. sa (0, 100 and 200 mg l-1) and put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. this study was conducted in a factorial experiment with complete randomized design on 108 narcissus cut flowers in horticulture laboratory of agriculture faculty of islamic azad university, jiro...

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...

rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

The main aim of this study was to evaluate the effects of silicon (Si), ethanol (Et), ascorbic acid (AA) and citric acid (CA) on vase life of Narcissus tazetta L. cv. ‘Shahla’cut flowers. For this purpose, an experiment based on completely randomized design was conducted with Si (5, 10 and 20 mM), Et (2 and 4%), AA (100, 200 and 300 mg L-1), CA (100, 200 and 300 mg L-1) and control (distillated...

This experiment was carried out to evaluate the effect of silver nanoparticles pulsing treatment (0, 25, 75 and 125 mg L−1) on vase life and some postharvest physiological parameters of cut rose flower ʻHigh & Magicʼ in sucrose solution (0, 2 and 3%). This research performed as a factorial experiment based on a completely randomized design with three replications under 23 ± 2 °C, 60 ± 5% RH and...

the effects of postharvest application of cobalt chloride were investigated on vase life of rose stood individually in vials and the other ones placing daffodil flowers in a vase with a rose flower.  therefore, roses were treated with: cocl 2 (100, 200, 300 mg l -1 , respectively) or distilled water (control). the results showed that the decreased vase life of rose flowers, after daffodil was p...

gerbera (gerbereajamesonii) cut flower has magnificent economical value in international cut flower industry. due to sensitivityto ethylene and to gray mold, it has a short postharvest life. in this research, the effects of pulsing treatments with salicylic acid (100 and 200 mg/l) and methyl jasmonate (25 and 50 mg/l) for 24h on quality and vase-life of gerbera cut flower were assessed. distill...
