Carnation (Dianthus caryophyllus L.) is valuable in terms of production and exports in the world. Increased vase life of cut flowers is an important factor for their market acceptability. For this purpose this study was carried out to examine the effect of plant essential oils as compared to 8-hydroxy-quinoline sulfate on the control of bacteria population and the longevity of carnation cut flo...

In this study, the effects of peppermint and rose extracts on delaying the aging of Alstroemeria spp. cut flowers were investigated. Peppermint and rose extracts were used in concentrations of 10, 20 and 30%. Quantitative and qualitative traits such as vase life, flower opening index, water uptake, fresh weight, dry weight, population of bacteria in vase solution and stem end, ion leakage, decr...

Regardless of their maturity at harvest, the vase life of cut inflorescences of the hybrid Limonium ‘Fantasia’ placed in deionized water was 4 to 5 days. A vase solution containing Physan (a quaternary ammonium disinfectant solution) at 200 μl•liter–1 and 20 g sucrose/liter not only prolonged the longevity of individual florets but also promoted bud opening so that the vase life of cut inflores...

Binding of the neural cell adhesion molecule (NCAM) in neurons to NCAM on non-neuronal cells can stimulate axonal growth. A developmentally regulated loss of this response is associated with the insertion of 10 amino acids (called VASE) into the fourth Ig domain in up to 50% of the NCAM receptors in neurons. In the present study we have transfected PC12 cells with the major neuronal isoforms of...

the aim of this paper was to assess the effect of catechol (ch), as a peroxidase inhibitor, and 8-hydroxyquinoline citrate (hqc), as a bacterial inhibitor, on keeping the quality of gerbera jamesonii cv. hongyan cut flowers, known to be limited by vascular occlusion. blockage in the stem xylem vessels of cut gerbera was studied using light and scanning electron microscope. the results showed th...

the postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. cut roses were obtained from commercial area of siliguri. to assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (ca) (300 mg/ml) and 8-...

We investigated the effects of sucrose and nano-silver (NAg) on extending the vase life of cut carnation flowers "Edun". Sucrose (pulse treatment) suppressed ethylene production by downregulating the genes that code for its biosynthesis. Relative to the control, however, sucrose significantly promoted xylem blockage on cut stem surfaces and reduced relative fresh weight, antioxidant activity, a...

The temporal sequence of neural processes supporting figure-ground perception was investigated by recording ERPs associated with subjects' perceptions of the face-vase figure. In Experiment 1, subjects continuously reported whether they perceived the face or the vase as the foreground figure by pressing one of two buttons. Each button press triggered a probe flash to the face region, the vase r...

Recent neuroimaging studies have described a differential activation pattern associated with specific object images (e.g., face-related and building-related activation) in human occipito-temporal cortex. However, it is as yet unclear to what extent this selectivity is due to differences in the statistics of local object features present in the different object categories, and to what extent it ...
