Genetic improvement of vase life of carnation ̄owers by crossing and selection
We used conventional cross-breeding techniques to develop many carnation lines with long vase life and either low ethylene production or low ethylene sensitivity. Two cycles of selection and crossing to improve vase life led to a 3.6-day increase in mean vase life. All 39 selected lines had signi®cantly longer vase life than the control cultivar, `White Sim'. In particular, second-generation li...
متن کاملSynergistic Effect of Nano-Sliver with Sucrose on Extending Vase Life of the Carnation cv. Edun
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...
متن کاملPsidium guajava and Piper betle Leaf Extracts Prolong Vase Life of Cut Carnation (Dianthus caryophyllus) Flowers
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...
متن کاملAntithyroid action of 3-amino-1,2,4-triazole.
It was first shown by Heim et al. (2, 3) that 1 hour after S-amino-l ,2,4-triazolel has been injected into rats, there is a marked inhibition of liver and kidney catalase, a lesser inhibition of liver peroxidase, and no inhibition of erythrocyte catalase activity. In view of this rather selective action towards tissue hydroperosidases, it seemed possible that aminotriazole should exhibit antith...
متن کامل2,4-Pyridinedicarboxylic Acid Prolongs the Vase Life of Cut Flowers of Spray Carnations
2,4-Pyridinedicarboxylic acid (PDCA) is a structural analog of 2-oxoglutarate and has been shown to inhibit 2-oxoglutarate-dependent dioxygenases by competing with 2-oxoglutarate, and ethylene production in detached carnation flowers by competing with ascorbate on 1-aminocyclopropane-1-carboxylate (ACC) oxidase action. In the present study, the inhibition of ACC oxidase action by PDCA was confi...
