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 sho...

The effect of exogenous salicylic acid (SA) on the vase life of cut rose flowers was investigated. ‘Yellow Island’ roses were obtained from a commercial grower. The roses were pulse treated with SA (0, 50, 100, 150, 200 mg l) for 18 hours. Compared to the control treatment (DW), the greatest delay in senescence was obtained in cut roses treated with 150 mg l SA. With this treatment, flower vase...

Any given verb can appear in some syntactic frames (Sally broke the vase, The vase broke) but not others (*Sally broke at the vase, *Sally broke the vase to John). There is now considerable evidence that the syntactic behaviors of some verbs can be predicted by their meanings, and many current theories posit that this is true for most if not all verbs. If true, this fact would have striking imp...

When viewing the Rubin face-vase illusion, our conscious perception spontaneously alternates between the face and the vase; this illusion has been widely used to explore bistable perception. Previous functional magnetic resonance imaging (fMRI) studies have studied the neural mechanisms underlying bistable perception through univariate and multivariate pattern analyses; however, no studies have...

Carnation (Dianthus caryophyllus L.) cv. Yellow Candy flowers were treated with ethanol solution (4%) in the absence or presence of 1 or 10 mM L-methionine, or ethanol or acetaldehyde solution (0.05%), in the absence or presence of 1 mM aminocyclopropane carboxylic acid (ACC). Spermidine in petals was measured over time in flowers treated with 4% ethanol or distilled water. Ethanol treatment si...

The experiment was carried out to investigate the effect of different concentrations of salicylic acid (SA), malic acid ( MA), citric acid (CA) and sucrose (Suc) on keeping quality and vase life of Chrysanthemum cut flowers. In this study three levels of malic acid (0, 100 and 150 mg l ) and salicylic acid (0, 1.5 and 3 mM) and two levels of sucrose (0 and 3% w/v) and of citric acid (0 and 150 ...

l’homme a toujours souffert du caractère impeccable du réel qui, imposant des répressions mentales et sociales, interdit la réalisation des souhaits et des désirs. pourtant il semble que rien ne puisse faire d’obstacles à l’esprit humain lorsqu’il prend la voie du rêve, ce phénomène compliqué et surnaturel. mais quelle est la fonction du rêve quand il entre dans le domaine de la littérature? pe...

Effect of salicylic acid combined with glutamin on rose (Rosa Baccara) cut flowers was studied. The study was conducted in a factorial arrangement, carried out in a complete randomized design. The factors were Salicylic acid (0,1, 2 and 4 mM) and glutamin (0, 1.5 and 3 mM).The effects of treatments on the total chlorophyll content, ACC-Oxidase activity, anthocyanin leakage, membrane stability a...

We investigated the role of nano-silver (NAg) and the bacterial strain Enterobacter cloacae in increasing the vase life of cut carnation flowers 'Omea.' NAg treatment extended vase life of the flowers by increasing relative fresh weight, antioxidant activities, and expression level of the cysteine proteinase inhibitor gene (DcCPi), and by suppressing bacterial blockage in stem segments, ethylen...
