The main postharvest disorder of cut gerbera flowers is the stem bending and break. The cause of stem bending is not completely clear. Although the genetic background seems to play the major role, some plant hormones such as ethylene and cytokinins may enhance or reduce the incidence of stem break during postharvest life. The choice of withstand genotypes seems to be a good strategy. In fact, s...

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...

Genetic improvement of flower vase life is an important breeding target for ornamental plants. As the cut dahlia (Dahlia variabilis) flowers very short, we initiated a conventional crossbreeding research program in 2014 to improve it. We evaluated seedlings during summer (from July early September) develop dahlias that grow and bloom under high temperatures have excellent Japanese conditions. C...

Rose is among the most important cut flower crops worldwide. The vase life an indicator of rose quality. composition solution directly affects life. Neoagaro-oligosaccharides (NAOS) are degraded seaweed-derived polysaccharides that constitute a group compounds with small molecular weight and good water solubility. Oligosaccharide treatment can extend postharvest longevity certain types flowers;...

An experiment was conducted to quantify luminescence of white cut flower carnations after exposure blue glow-in-the-dark powder. Powder applied the flowers as either dip (3, 6, or 9 g) spray solutions in 240 mL water for 4 seconds plus a control. Stem fresh weight, relative stem diameter, and overall solution absorption were greatest on day 4. Only 6-g had greater average quality ratings than c...
