It has been generally thought that in ethylene-sensitive plants such as carnations, senescence proceeds irreversibly once the tissues have entered the climacteric phase. While pre-climacteric petal tissues have a lower sensitivity to ethylene, these tissues are converted to the climacteric phase at a critical point during flower development. In this study, it is demonstrated that the senescence...

Dianthus caryophyllus L. is an important floricultural crop species throughout the world, specially in Eurasia. The present study was conducted to evaluate the nine Dianthus genotypes, including normal and mutagen treated, to assess the magnitude of variability and to pick up the heritable component of variation present in the quantitative traits. The analysis of variance revealed highly signif...

We present a mathematical model for a dynamic Delphi survey method which takes advantages of Web technology. A comparative study on the performance of the conventional Delphi method and the dynamic Delphi instrument is conducted. It is suggested that a dynamic Delphi survey may form a consensus quickly. However, the result may not be robust due to the judgement leaking issues.

Among the typical dissertation research designs, one particular design that is slowly gaining acceptance is that of the Delphi Method. Using a panel of experts to achieve consensus in solving a problem, deciding the most appropriate course of action, or establishing causation where none previously existed, particularly in areas of business or education research, are uniquely ideal to employment...

The carnation (Dianthus caryophyllus) is one of the top-selling commercial cut-flower crops worldwide, which is very susceptible to infections. Micro propagation is an advanced biotechnological system for producing free of pathogen colonies. Too many factors may limit micro propagation of plants, which the most important of them is contamination (e.g., fungal, bacterial and viral infections). T...

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 ...

Much research has been devoted to the Delphi technique. However, very little substantive work has been done on the subject of Delphi accuracy. The purpose of this effort was to test the accuracy of Delphi vs the conference method in making long-range forecasts. College students were used to form Delphi and conference groups that predicted the point spreads of college football games far in advan...

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...
