During the cold season, it is known that the tulip bulbs (Tulipa gesneriana L.), which are specialized underground organ, go through a series of physiological (respiration and transpiration) and biochemical changes (mass loss and total soluble solids). The main purpose of this study is to compare the physiological parameters changes during storage in cold room conditions of ten tulip cultivars (Allegretto, Margarita, Menton Exotic, Lion King, Sensual Touch, Jaap Groot, Marilyn, Indiana, Atlantis, Washington), before and after storage period. The samples were stored in conditions like: T: 1°C and RH: 90%, in the Research Center for Studies of Food Quality and Agricultural Products, of the USAMV Bucharest. From obtained results it was observed decreases with 10% of the mass loss between the initial and the final moment of analyses for Allegretto, Menton Exotic, Sensual Touch cultivars. For respiration rate were observed increases with 25% (for Lion King cv.) up to 6.6 times more (for Menton Exotic cv.) between the initial and final moments.
