The nectarine is a variation from the peach, mainly characterized by the circumstance that, while the skin of the ripe fruit is downy in the peach, it is shining and destitute of hairs in the nectarine.
The history of the peach almond and nectarine is interesting and important as regards the question of the origin of species and the production and perpetuation of varieties.
As to the nectarine, of its origin as a variation from the peach there is abundant evidence, as has already been mentioned; it is only requisite to add the very important fact that the seeds of the nectarine, even when that nectarine has been produced by bud-variation from a peach, will generally produce nectarines, or, as gardeners say, "come true."
So far as we know, however, no case has yet been recorded of a peach or a nectarine producing an almond, or vice versa, although if all have had a common origin such an event might be expected.
It may, however, well be that both peach and almond are derived from some pre-existing and now extinct form whose descendants have spread over the whole geographic area mentioned; but this is a mere speculation, though indirect evidence in its support might be obtained from the nectarine, of which no mention is made in ancient literature, and which, as we have seen, originates from the peach and reproduces itself by seed, thus offering the characteristics of a species in the act of developing itself.
The treatment in horticulture of the peach and nectarine is the same in every respect.
The Stanwick nectarine, so apt to crack and not to ripen when worked in the ordinary way, is said to be cured of these propensities by being first budded close to the ground, on a very strong-growing Magnum Bonum plum, worked on a Brussels stock, and by then budding the nectarine on the Magnum Bonum about a foot from the ground.
Thus in the peach, nectarine, apricot, plum and cherry, which are commonly trained fan-fashion, the first three (and also the morello cherry if grown) will have to be pruned so as to keep a succession of young annual shoots, these being their fruit-bearing wood.
This mode of training is commonly adopted for the peach, nectarine, apricot and morello cherry, to which .
The best walls having a south or south-east aspect are devoted to the peach, nectarine, apricot, dessert pears, plums and early cherries.
Among the many economic plants which have been introduced into Chile and have become important additions to her resources, the more prominent are wheat, barley, hemp and alfalfa (Medicago sativa), together with the staple European fruits, such as the apple, pear, peach, nectarine, grape, fig, olive and orange.
