(Prunus persica variety nectarina), smooth-skinned peach of the family Rosaceae, known for more than 2,000 years and grown throughout the warmer temperate regions of both the Northern and Southern hemispheres. In tree shape and leaf characteristics the peach and nectarine are indistinguishable, but nectarine fruits look more like plums than peaches because of the smooth skin. The stones and kernels of the two fruits are alike in appearance. Nectarines have red, yellow, or white flesh and are a source of vitamins A and C. They are commonly eaten fresh, or cooked in conserves, jams, and pies.
As in peaches, there are clingstone and freestone nectarines. When some peaches are crossed or self-pollinated, the resulting seeds that carry the factor for smooth skin may give rise to nectarines, while those that do not carry this factor will be peaches. Nectarines may sometimes appear on peach trees as a result of the process of bud variation, or bud sporting, a vegetative deviation from the normal. Cultivation of nectarines is essentially the same as for peaches, with best results usually obtained on well-drained sandy or gravelly loams, enriched with nitrogen.

Young peach and nectarine fruits may drop early or are knobby with discoloured warty spots; plum fruits become greatly swollen, distorted, and hollow (plum pockets); witches’-brooms may form on alder,...
...that separate easily from the ripe flesh, or clingstones, which have flesh that adheres firmly to the stone. The skin of most ripe peaches is downy or fuzzy; peaches with smooth skins are called nectarines.
