In order to evaluat the effects of banzyladenine (BA)‚ gibberellic acid(GA3) and cold, dry storage on the longevity of liliumcut flowers (cv. Fangio) an experiment was conducted as a factorial based on randomized complete block design with three replications. Cut flowers were treated with 100 mg/lit BA plus 100 mg/lit GA3 and distilled water (control) as a short-term pretreatment for 24 hours, then they kept in dry storage in 4ċ for 10 days. In dry storage, flowers were sprayed with 2 ppm nano silver or distilled water. After storage, cut flowers were placed in preservative solution containing 2 ppm nano silver plus 3% sucrose and were evaluated until the end of vase life. Results showed that addition of BA+GA3 (100mg/lit of each) as a pulsed treatment in solution for 24 hours prior cold storage increased petals anthocyanin, vase life (P<1%) and membrance stability index (P<5%) and decreased percentage of blasted buds and chlorophyllase activities. Stems kept in dry storage at 4ċ and then treated with preservative solution containing 2 ppm nano silver plus 3% sucrose produced the longest vase life (P<5%) and decreased percentage of blasted buds (P<5%).
