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...
