Investigations on “natural” cuticular cracks were conducted nectarine fruit [ Prunus persica (L.) Batsch var. nucipersica (Suckow) C.K. Schneid.]. A method for quantifying the crack surface area a whole basis was proposed. By using stratified sampling design, spatial distribution of over three regions (stylar end, peduncle, and cheek), their morphology, estimation total proportion studied. These features examined during development in response to several growing conditions corresponding various crop loads irrigation regimes. Cuticular occurred final rapid growth stage. Larger presented higher densities apical than cheek regions. Thin larger continuously development. represented 10% 12.5% well irrigated or low load trees, whereas they covered less 4.5% heavy water deficit treatments. Cheek largely contributed (>60%), regardless conditions. After restricted, limited. positive relationship established between per fresh weight.
