Effect of Chemical Treatments and Sucrose on Vase Life of Three Cut Rose Cultivars

A study was carried out to investigate the effect of chemical treatments and sucrose on vase life of three new rose cultivars, ‘Bouing’, ‘Creamly’ and ‘Sena’. Treatments were included distilled water (control), 10 g l -1 sucrose, 10 g l -1 sucrose + 100 mg l -1 citric acid, 10 g L -1 sucrose + 100 mg l -1 aluminium sulphate, 10 g l -1 sucrose + 0.5 mM silver thiosulphate for 2 h . Results showed that the best treatment for ‘Sena’ was silver thiosulphate + sucrose that increased fresh weight, water uptake, flower diameter and flower vase life. On the other hand, this treatment caused petal burning in ‘Creamly’ in spite of its other improved traits. Best treatment for other cultivars was citric acid + sucrose that had significant effect on all investigated factors. Aluminium sulphate just had a positive effect on ‘Sena’. This treatment did not have positive effect in ‘Creamly’ and even decreased vase life of ‘Bouing’ in comparison with control.
