Some of the postharvest physical properties of six cultivars of Iranian apricot fruits are presented in this study. Information about these properties is very important for understanding the behaviour of the product during the postharvest operations, such as harvesting, transporting, sorting, grading, packaging and storage processes. This research was undertaken to study some physical properties of six Iranian apricot cultivars (Shams, Nakhjavan, Djahangiri, Sefide Damavand, Shahroud-8, and Gheysi-2). These properties include: linear dimensions, geometric mean diameter, projected area, criteria projected area, surface area, sphericity, volume, mass, bulk and average fruit density, packaging coefficient, coefficient of static friction, and ratio of length to width (L/W), length to thickness (L/T), and length to mass (L/M).
