1-mcp, as an ethylene action inhibitor, significantly delayed the wilting of cut carnation.this study was carried out to determine the optimum concentration and duration of 1-mcp application on vaselife of cut carnation c.v 'tempo'. six levels of 1-mcp concentrations (0,20,40, 60, 80 and 100 nl.1-1) as well as three application times (3, 6 and 9 hours) were studied in a factorial comp...

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 ...

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...

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 lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporaDly with petal-inroDling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...

carnation is considered as the world's third most important cut flower. tissue culture techniques offer suitable method for micropropagation of this ornamental plant. however, one of the problems during in vitro culture of carnation is vitrification. ratio of ammonium to nitrate and agar concentrations in the medium affect this phenomenon. therefore, in this study the effect of these factors on...

An experiment entitled Influence of organic manures on growth, flowering, quality and yield carnation (Dianthus caryophyllus) cv. Master under naturally ventilated polyhouse conditions Prayagraj was conducted in Department Horticulture, Naini Agricultural Institute, SHUATS, Prayagraj, during November, 2022 to April, 2023 with an aim identify the most suitable manure combination agroclimatic Pra...

Abstract Standard Carnation flowers (Dianthus caryophyllus cv. Dover) were harvested at the paint brush stage in early morning, pre-cooled 4° C for 6-h then moved under dry conditions to laboratory. Flowers weighted and treated 24-h with silver nanoparticles (AgNPs) 0, 5 or 10 ppm plastic buckets. After pulsing treatments, cut transferred 500 mL glass jars containing 300 of preservation solutio...

Temperature, an environmental factor affecting cut flowers' physiological state, is expected to affect scent emission. We investigated emission from carnation flowers of two types (Dianthus caryophyllus L.), exhibiting fruity (because methyl benzoate) and spicy eugenol) scents, at various temperatures (10°C, 15°C, 23°C, 28°C). Cut harvested on the day flower opening were used for analysis. Scen...
