Effects of 1-methylcyclopropene (1-MCP) at 200 mg·m−3, silver nanoparticles (AgNPs) at 100 mg·dm−3 and sodium nitroprusside (SNP) at 0.3 mM on relative water content (in %) of carnation cut flowers over vase life period. Values are means ± SE (n = 15). Letters represent statistical differences among treatments at each vase life day at 5% probability.
