Application of postharvest treatments to cut flowers.   Flowers cut stems often have a short vase life, showing in few days decolouration of petals, a rapid browning of tissues, loss of single components of the flower and total senescence.Such problem determines a shorter vase life, so flowers don’t result more available, after few days from harvest.To prevent such delay, a system of packaging (Modified Atmosphere, MA) that consist to introduce in the package different gaseous mixtures, to reduce decolouration of petals and to increase vase life of flower, can be used.

Some tests o­n three cultivar of Gerbera, two cv. Of Lilium and two of Rose were carried out to find the suitable atmosphere, packaging flowers with three different gaseous mixtures: o­ne represented by the normal air (A = 78% N2 – 21% O2 – 1% CO2) and two without O2 (B = 100% N2; C = 90% N2 – 10% CO2).Wraps were subsequently preserved at 4 + 1 °C.Packaging opening was effected after 3, 6, 9 and 12 days of storage in MA.The method used to effectuate this first screening is founded o­n the aspect assumed by flowers during the shelf life, and o­n the instrumental analyses results, comparing such data with the analyses o­n the product not packaged (control).Flowers vase life was evaluated after the opening of wraps, at 20 °C, as well as the daily water consumption.

The gaseous mixture containing air conferred a greater vase life for Gerbera and Lilium, in comparison to the control, while for Roses the mixture B results to be the best.
