In this research, several physical, pomological and nutritional properties of two plum ( Prunus domestica L.) cultivars (Stanley and Frenze 90) grown in the Antalya region were determined. These properties are necessary for the design of equipments for harvesting, processing, transportation, sorting, separating and packing. In Stanley cultivar plums, the average fruit length, width, thickness, the geometric mean diameter, sphericity index, fruit mass, thousand of fruit mass and volume of fruit were 48.25 mm, 33.24 mm, 31.32 mm, 36.48 mm, 76.30%, 27.97 g, 28569.60 g and 29.05 cm 3, respectively. The bulk density, fruit density and porosity were 642 kg/m 3, 1050 kg/m 3 and 38.99%, respectively. The coefficient of static friction on rubber, plywood and galvanized sheet of plum cultivars were 0.194, 0.187 and 0.164, respectively. The moisture content, titratable acidity, skin and flesh firmness and organic matter were 89.00%, 0.38%, 1.75 kg, 0.67 kg and 96%, respectively. Protein, K, Ca, P and N amount were 2.81%, 1.16%, 0.12%, 0.09% and 0.45%, respectively. In Frenze 90 cultivar plum, however, the average fruit length, width, thickness, the geometric mean diameter, sphericity, unit mass, thousand of fruit mass and volume of fruit were 58.33 mm, 47.70 mm, 45.49 mm, 50.00 mm, 85.80%, 71.99 g, 52313.00 g, 72.05 cm 3, respectively. The bulk density, fruit density and porosity were 572 kg/m 3, 1029 kg/m 3 and 44.25%, respectively. The static friction coefficient on rubber, plywood and galvanized sheet were 0.147, 0.127, and 0.125, respectively. The moisture content, titratable acidity, skin and flesh firmness and organic matter were 87.00%, 0.89%, 2.01 kg, 1.09 kg and 99.00%, respectively. Protein, K, Ca, P and N amount were 3.88%, 1.41%, 0.15%, 0.13% and 0.62%, respectively.
