The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...

to study the effect of nitric oxide on longevity and some qualitative characteristics of cut carnation flowers (dianthus caryophyllus cv. nelson), cut flowers were treated for 48 hours with sodium nitroprusside (snp) as a source of no° donor at four concentrations (0, 20, 50 and 100µm) alone and in combination with other such ethylene inhibitors as thidiazuron and sucrose in a completely random...

Nitric oxide (NO) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. The research on the application of NO to postharvest preservation of flowers and fruits shows great promise in recent years. However, the physiological mechanism of exogenous NO to affect cut flowers is not very clear, and NO donor treatment protected plants from damage by increasing ...

The respiration of cut flowers of rose (Rosa hybrida L. ‘First Red’) and gypsophila (Gypsophila paniculata L. ‘Bristol Fairy’) increased exponentially with increasing respiration, with a Q10 value between 0 and 10°C of 3 for both flowers. The vase life of the flowers was negatively affected by simulated transport at higher temperatures whereas dry storage for 5 days at 0°C resulted in a vase li...

this experiment was conducted in national institute of ornamental plants for extending vase life of anturium andranum cv. climax cut flowers. experiment was done based on completely randomized design (crd) with three replications and three cut flowers per replicate. treatments included volk oil emulsion wax coating (10, 20 and 30 percent), thyme oil (100, 150 and 250 ppm), salicylic acid (200, ...

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...
