Comparison some of the morphological, physiological traits and vase life of cut rose flowers cv. grand prix by putrescine, spermine and spermidine

Vase life of cut flower plays important economic values in flower production industries. The effects of putrescine, spermine and spermidine on cut Rose was studied. putrescine, spermine and spermidine (100 and 200 mg l-) and their combinations with sucrose (3%) and silver nanoparticles (4 mg 1-) were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design. The recorded traits included vase life, SOD content, and solution uptake. The results shown that level of 200 mg -1 spermine to increase of SOD content, vase life and solution uptake.
