Effect of silver nanoparticles, spermine, salicylic acid and essential oils on vase life of Alstroemeria

In this study, effects of different concentrations of silver nanoparticles (NS), salicylic acid (SA), spermine (SP), dill (AN), and cumin (CM) essential oils were investigated on physiological and microbiological traits of alstroemeria (Alstroemeria hybrida) cut flowers during a preharvest and postharvest application. The study was performed as a factorial experiment based on a randomized completely design with three replications. During the experiment the vase life of cut flower was evaluated in terms of chlorophylls a, b and total, superoxide dismutase (SOD), lipid peroxidation (MDA), stem and bacterial colonies and bacterial identification. The results showed that using high concentrations of nanosilver (NS2) increased significantly the vase life of cut Alstroemeria in preharvest and postharvest. 11 colonies of bacteria were identified in stem end of cut alstroemeria flowers.
