The Effect of Eucalyptus and Rosa Damascena Essences With Sucrose on Vase Life and Physiological Characteristics of Cut Gerbera Cv. ‘Alain Ducasse’

Gerbera cut flowers is one of the important and popular cut flowers inthe world that regardless of increasing production of this plant in iran, theduration of its life is short due to rapid wilting petals and bending neck offlower. to increase vase life of gerbera cut flowers cv. ‘alain ducasse’, theessences of eucalyptus and rosa damascena, the combination of these twoessences at a concentration of 200 mg l-1 with 4% sucrose and only 4%sucrose were used as treatment and distilled water was used as controltreatment. in current study, the characters of vase life, wet weight, totalsoluble solids, solution uptake and bent neck were examined. maximum andminimum of vase life were achieved in eucalyptus essence treatment (12.33days) and control (7 days), respectively. although, rosa damascena essenceand its combination with eucalyptus essence also increased the vase life. themaximum fresh weight and solution uptake was obtained treated witheucalyptus oil. the maximum fresh weight and absorption of solution wereobtained in treatment with eucalyptus essence. the maximum amount ofsoluble solids was obtained in the treatment of sucrose. in addition, controltreatment has the maximum bent neck. the overall results showed that theuse of eucalyptus and rosa damascena essence in combination with sucrosecan be used as a preservative solution of gerbera cut flowers.
