This is study was conducted in the Postharvest Lab of Ornamental Plants and Landscape Gardening Res. Dept., Hort. Res. Inst., Giza, Egypt in March of 2014 and 2015 seasons, aiming to assess the efficiency of some antiseptic solutions to improve the quality of Anthurium andraeanuminflorescence. Cut flowers were immersed for 3 h in benzyladenine (BA) at 10 mg l-1 plus sucrose at 25 g l-1 and then transferred to the following antiseptic solutions viz. nano-silver (NS) at 5, 10 and 15 mg l-1, calcium chloride (CaCl2) at 0.5, 1.0 and 1.5 g l-1 + 8- hydroxyquinoline (HQ) at 0.2 g l-1 and Stevia rebaudiana extract at 0.1, 0.2 and 0.3 mg l-1 all of these at different concentrations and combinations were combined with sucrose at 20 g l-1. Distilled water was used (D.W) as control. Data revealed that treatment of cut flowers with NS at 15 mg l-1 prolonged shelf life, maintained relative fresh weight and water balance, raised percentage of dry matter of flowers, reduced microbial count, enhanced some visual characteristics such as spadix condition as spathe blueing, spathe glossiness and stem condition.It had positive effects on total sugars and total carbohydrates content whilst Stevia extract at 0.1mg l-1 increased the rate of water uptake after fifteen days from placing the flowers in the solution. NS at 10 mgl-1 decreased water loss.
