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...

chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. in order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a rcd with 10 treatments: artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), ri...

the aim of this study is investigation on effect of stem end splitting and geranium essential oil on vase life on quality of cut chrysanthemum (dendranthema grandiflorum l.). this experiment arranged as factorial based on rcd with 2 factors of stem end splitting at 2 levels (with splitting and without splitting) and geranium essential oil at 6 levels (0, 1, 2, 4, 8 and 10 %), with 12 treatments...
