Abstarct: Given the economic importance of flower in Iran and the world, post-harvest losses flower is one of the most important problems in this industry and an important barrier to export and exchange of technology in the country. The flowers longevity depend on several factors, mainly into two categories of pre-harvest and post-harvest factors divided. Crop improvement factors reducing plant stress caused by separation from the mother's flowers. Minerals such as calcium and boron in addition to effects on plant growth, also it affect on vase life of flowers. Ethylene inhibitor compounds and antibacterial of the most common materials used in post-harvest of the flowers. Silver compounds due to it Nano-sized, increase in surface area and properties Ethylene inhibitor in the vase solution is a proper combination. To investigate the effect of calcium, boron, nanosilver (particle size of 5 nm) and synthetic Nano-silver carbon-baxsed on Lilium flower to trial in 2014, just two factorial experiment baxsed on randomized complete block design with three replications. Factors include calbonex fertilizer (containing 10% calcium and 2 percent of boron in fertilizer unit) in three levels (0, 2 and 4 ml per liter) The first factor common to both experiments, Nano-silver (0, 1, 3 and 5 ppm) second factor in the first test and synthetic Nano-silver carbon-baxsed factor (0, 1, 3 and 5 ppm) The second factor was the second test. The results showed that use of calbonex increasing calcium and boron the leaves and reproductive traits such as number of buds, bud diameter, pedicle diameter, the number of flower and vegetative traits such as leaf number, stem diameter and chlorophyll. The use of Nano-silver treatments in post-harvest could be combined with calbonex traits increase such as vase life, inflorescence the vase-life, chlorophyll, relative fresh weight, relative the absorption solution and yellowing of leaves, electrolyte leakage of leaves and flowers, vase solution hydrogen ion concentration, protein, catalase and peroxidase guicol and malon dialdehyd and also over time the reduce number of bacteria vase solution. The trilateral interaction in the first experiment, 5 ppm Nano-silver with 4 ml/L calbonex could be traits like relative fresh weight and relative solution uptake increase, reduced the number of bacteria vase solution. Combined treatment of 3 ppm Nano-silver with 4 ml/L calbonex showed the best results in hydrogen ion concentration vase solution. In the second experiment, three-way interactions of the synthesis Nano-silver of 5 ppm in combination with 4 ml/L calbonex to increases the relative solution uptake and relative fresh weight, the number of bacteria reduced the vase solution. In this experiment, 5 ppm synthetic Nano-silver with 2 ml/L calbonex reduced electrolyte leakage of leaves and flowers. Showed a significant decrease The hydrogen ion concentration vase solution of 1 ppm synthetic Nano-silver with 4 ml/L calbonex. In general, the survey results Nano-silver against synthetic nanosilver treatment is more effective in improving post-harvest. In this study, favorable results were obtained by 5 mg per liter Nano-silver.
