Psidium 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 کاملComparison of mRNA levels of three ethylene receptors in senescing flowers of carnation (Dianthus caryophyllus L.).
Three ethylene receptor genes, DC-ERS1, DC-ERS2 and DC-ETR1, were previously identified in carnation (Dianthus caryophyllus L.). Here, the presence of mRNAs for respective genes in flower tissues and their changes during flower senescence are investigated by Northern blot analysis. DC-ERS2 and DC-ETR1 mRNAs were present in considerable amounts in petals, ovaries and styles of the flower at the ...
متن کاملEthylene Production and Petal Wilting during Senescence of Cut Carnation (Dianthus caryophyllus) Flowers and Prolonging Their Vase Life by Genetic Transformation
Senescence of carnation flowers is characterized by autocatalytic ethylene production from petals and subsequent wilting of the petals. Recent studies on the regulation of ethylene production and wilting in senescing carnation petals revealed that (1) petal senescence is triggered by ethylene evolved from the gynoecium during natural senescence, (2) ethylene production in the gynoecium is induc...
متن کاملEffects of Chemicals on Vase Life of Cut Carnation( Dianthus caryophyllus L. 'Delphi ') and Microorganisms Population in Solution
The vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. Reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitations and air emboli. Cut flower and foliage longevity can be greatly affected by t...
متن کاملComparison of Plant Growth Regulators and Exogenous Ethylene Effects on Two Types of Cut Carnation (Dianthus caryophyllus L.)
The main object of this study is to investigate the effect of plant growth regulators on the prolongation of vase life of two kinds of cut carnation under normal and ethylene. Carnation is one of the most popular flowers that has a short life due to its sensitivity to ethylene. Also, the effect of plant growth regulators on several physiological traits under ethylene stress and normal condition...
