Assessment of concurrent of the sucrose and silver nitrate on cut flower of rose (Rosa hybrida cv. 'Red One')

The rose plant is one of the most widely sold and appreciated ornamental flowers throughout the world. Vase life of cut rose flowers is usually short. Hence, we studied effect of sucrose combined with silver nitrate on rose (Rosa hybrida) cut flowers. The study was carried out in a completely randomized design. Sucrose was used in one concentration (5%w/v) and silver nitrate with four concentrations (0, 10, 20 and 30 ppm). Characters such as vase life, flower quality, water uptake, and leaf chlorophyll, fresh and dry weight were measured. Results showed that there were not significant differences between fresh weights of cut flowers at the end; but in dry weight treatment by 30 ppm silver nitrate had significant difference than others. Also, vase life of cut flowers was the most in treatment by sucrose 5% simultaneous 30 ppm silver nitrate. We conclude that sucrose and silver nitrate treatment have significant effect on quality parameters of rose cut flowers and can maintain the vase life of flowers for a longer period. So we recommend that using sucrose and silver nitrate can improve vase life of rose cut flowers.
