carnation etched ring virus (cerv) is a member of the caulimovirus genus of the caulimoviridae. the virus is the second most important virus of carnation around the world and the only dna virus among infecting viruses of carnation. the virus infected plants were collected from greenhouse in chenaran and two fragments of ~1500 bp and ~1000 bp respectively for coat protein and movement protein we...

In present investigation, for the development of Fusarium tolerant varieties in carnation, highly susceptible cultivars viz. Tempo and Raggio de Sole were used. Calli caraation irradiated to different doses gamma irradiation. And Callus surviving at highest dose rays was mass multiplied on callus multiplication medium (MS +10 μNAA + 10 μM kin). Irridiated calli after multiplication, treated wit...

The rates of CO2 assimilation by potted spray carnation plants (cv. Cerise Royalette) were determined over a wide range of light intensities (45-450 W m~ PAR), CO2 concentrations (200-3100 vpm), and leaf temperatures (5-35 °C). Assimilation rates varied with these factors in a way similar to the response of single leaves of other temperate crops, although the absolute values were lower. The opt...

A glutathione S-transferase-like gene, DcGSTF2, is responsible for carnation (Dianthus caryophyllus L.) flower color intensity. Two defective genes, DcGSTF2mu with a nonsense mutation and DcGSTF2-dTac1 containing a transposable element dTac1, have been characterized in detail in this report. dTac1 is an active element that produces reverted functional genes by excision of the element. A pale-pi...

The addition of potassium bicarbonate to the electrode cuvette immediately stimulated the rate of dark O(2) uptake of photomixotrophic and heterotrophic carnation (Dianthus caryophyllus L.) callus, of Elodea canadensis (Michx) leaves, and of other plant tissues. This phenomenon occurred at pH values lower than 7.2 to 7.8, and the stimulation depended on the concentration of gaseous CO(2) in the...

abstract reduction of post harvest losses in cut flowers and increasing their vase life, with consideration to high expenses of production is very necessary. one of the effective factors is presence of flowers near each other. this study was performed to investigate the interaction of some important cut flowers on their post harvest characteristics in vase solution (in combination or alone) in ...
