Santarosa plum is the red plum that its scientific name is Prunus americana. In this study, some physical and mechanical properties of Prunus americana with moisture content of 89.66% (w.b.) were discussed. Physical properties such as height, length, width, weight, geometric mean diameter, arithmetic mean diameter, shape, aspect ratio, volume, true density, image rates in line with PA, PB and PC, the surface area and sphericity, respectively, which were 19.44 mm, 18.57 mm, 18.03 mm, 6.71 g, 18.76 mm, 18.77 mm, 1.06, 4.39 (mm3), 1.07 (g/cm3), 313.2 (mm2), 302.97 (mm2), 284.35 (mm2), 300.17 (mm2), 1112.46 (mm2) and 96.28. Mechanical properties were measured by uniaxial loading. Plums were placed between two parallel plates (fixed and mobile) and forced until reaching the failure point. The results showed that in average peak force, failure force, failure strain, energy to peak force and Energy to break force for
loading in vertical line were respectively, 157.68 (N), 96.16 (N), 0.4148, 0.5237 (N/m) and 0.6862 (N/m) and for loading in horizontal line were respectively, 172.14 (N), 111.58 (N), 0.4221, 0.3890 (N/m) and 0.6914 (N/m). All values of loading in horizontal line were greater than vertical values, whiles, for energy to peak force values were greater in the horizontal direction
