Abstract
The effect of exogenus sucrose and two different periods of cold storage (2 °C) on the vase life of roses ‘Serena’ was studied.
Pulsing treatment containing 80 g· l-1 of sucrose and 200 mg· l-1 of 8-Hydroxyquinoline sulphate.
It is a positive effect to prolong the vase life of roses in comparison with roses not pre-treated and cold storage for 6 days.
About the evolution of opening stages of flowers pre-treated and stored for 3 and 6 days, they take some time to reach stage 7 (petals show discoloration and pistils are blackening). Instead flowers that are not pretreated and are followed by 3 or 6 days in refrigerator reach only stage 5 (pistils visible).

Instead flowers that are not pretreated and are followed by 3 or 6 days in refrigerator reach only stage 5 (pistils visible).
In all the treatments there was an increase in weight after 6 hours (time of pulsing). Then while the stems remaining in distilled water all the time gained fresh weight till day five when the decrease started, the weight of the flowers of all the other treatments, except flowers pre-treated followed by 6 days in cold storage, when removed from the refrigerator, and was lower than the initial one.
