AB  - The usual puncture test was applied to determine some mechanical properties of Golden Delicious and Red Delicious apple and effect of skin on this parameters. The difference between overall puncture load displacement (whole fruit) and that measured without skin provide a satisfactorily precise result related to mechanical behavior of skin itself. This procedure is applied to evaluate the effect of skin on mechanical behavior of apple. Skin has an effective role in most puncture properties of the apple. Skin cause to increase in maximum force of compression, firmness, toughness, lam`s coefficient and elastic modulus of the apple. The kind of varieties has a significant effect on force, firmness, lam coefficient (µ) and elastic modulus of apple. For two varieties of apple skin has a high percent of toghness and rupture force but the contribution of skin in Golden  Delicious  apple  is  higher  than  Red  Delicious  apple.  The  contribution  of skin in deformation for 2 varieties is few.
