The effects of concentrations of various biocides, in a solution containing 0.2 g l citric acid and 10 g l glucose, were tested on cut roses (Rosa hybrida L., ‘Classy’), Alstroemeria pelegrina L. and carnations (Dianthus caryophyllus L.). Compounds were evaluated for their effects on flower life (time to decline in fresh weight), maximum gain in fresh weight, solution uptake from 4 to 6 days, r...

The scent of roses (Rosa x hybrida) is composed of hundreds of volatile molecules. Monoterpenes represent up to 70% percent of the scent content in some cultivars, such as the Papa Meilland rose. Monoterpene biosynthesis in plants relies on plastid-localized terpene synthases. Combining transcriptomic and genetic approaches, we show that the Nudix hydrolase RhNUDX1, localized in the cytoplasm, ...

The respiration of cut flowers of rose (Rosa hybrida L. ‘First Red’) and gypsophila (Gypsophila paniculata L. ‘Bristol Fairy’) increased exponentially with increasing respiration, with a Q10 value between 0 and 10°C of 3 for both flowers. The vase life of the flowers was negatively affected by simulated transport at higher temperatures whereas dry storage for 5 days at 0°C resulted in a vase li...
