Effect of Temperature on Scent Emission from Carnation Cut Flowers

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. Scent was significantly higher 23°C 28°C than 10°C 15°C until 1 or 2 days but lower 8 10 postharvest. Methyl benzoate emissions decreased faster eugenol emissions. Considering limit noticeable scent, as per previous sensory evaluations carnations, lasted longest 15°C. After ~5 pretreatment 10°C, slightly improved 23°C. Such management before sale may contribute persistence room temperature in consumers' homes after sale. Various factors, including suppression substrate consumption, regulation cuticle, influence expression emission–related genes, retention because low temperature.
