The effects of pulsing solutions comprising an ethylene action inhibitor (sliver thio-sulphate (STS), carbohydrates (CHOs) such as glucose (Glu), fructose (Fru) or sucrose (Suc) and biocides (BIOs) Aluminium sulphate (Al2(SO4)3) or 8-Hydroxyquinoline sulphate (HQS)) on the vase life of rose (Rosa hybrida L.) cultivar Red CalypsoTM' cut flower stalks were evaluated in a series of laboratory experiments, conducted in the crop protection laboratory (EIAR, Holleta). The pulsing treatments were arranged in a 2 × 4 × 3 factorial combinations that included STS (0 or 0.225 mM), CHOs (0, D+ Sucrose (20 g l-1), D- Glucose or D- Fructose (10 g l-1) each) and BIOs ( 0, Al2(SO4)3 (1 g-1) or HQS (0.4 ml l-1), in Completely Randomized Design (CRD), with three replications.
