Abstract: Agricultural crops in our country have a lot of waste, so it is necessary to pay attention to its post harvest stage. In order to investigate the effect of foliar application of Calcium chloride and silica nanoparticles on fruit quality characteristics of Golden Drop plum, an experiment was conducted under field conditions in the research orchard of Shahed University. This experiment was carried out based on completely randomized design with combined treatments of Calcium chloride and silica nanoparticles with 4 replications. Treatment concentrations were considered 4 levels of Calcium chloride (0, 500, 1000, 2000 mg/L) and 3 levels of silica nanoparticles (0, 200, 400 mg/L). Zero levels of both compounds as well as spraying with distilled water was considered as control treatment. The results showed that all levels of treatments in compared with control have a significant effect on fruit characteristics including fruit fresh weight, firmness, length and diameter, total soluble solids (TSS), Vitamin C, pH and titratable acidity (TA). 200 mg of silica in combination with 1000 mg of Calcium chlorid and treatment of 400 mg of silica in combination with 1000 mg of Calcium chloride had the highest effect on the fruit qualities and morphological characteristics. It seems that foliar application of calcium chloride and silica nanoparticles can improve qualitative characteristics in the post-harvest stage of plum fruits.
