ABSTRACT
Tulips is one of the most important cut flowers in the world. For the first time, the efficacy of nano silver (NS) in extending the vase life of cut tulip ‘White Parrot’ was evaluated. Cut flowers were kept in solutions containing 0, 10, 20 and 40 mg L-1 NS. The NS treatments at all concentrations extended the vase life of cut flowers. The 10 mg L-1 NS treatment produced the longest vase life, as compared to the control. On the last day of decorative value, the greater fresh weight was observed in the flowers exposed to the solution of NS in 10 or 20 mg L-1. NS at 20 or 40 mg L-1 prevents the leaves from yellowing.
