L has apple is a fruit (in fact, a false fruit ) fleshy, almost spherical shape, depressed at the top and base, pulp homogeneous (unlike pears containing cells sclerotized or stony). Some old varieties had forms particular, as the small apple rather flat and star-shaped pentagonal , or pigeonnet of Rouen, on the contrary very elongated. The lemon pippin English, old cooking apple, had the shape and color of a lemon .
Its size varies by variety and growing conditions . Color at maturity, ranging from green "apple" in red more or less dark through a variety of intermediate pale green, yellow, orange or color more or less panachées.Au top of the fruit (side opposite to the insertion of rake), we can see the remains of the sepals dried. Indeed, the apple comes from a merger so-called " inferior ovary and adherent, that is to say that the perianth , including sepals and petals lies at the top of the ovary and the latter is welded to the floral receptacle .
On the botany, apple is a fruit complex, intermediate between Bay and drupe . Some botanists call " piridion " this type of fruit, typical of the tribe Maleae . In a cross-section can be seen at the center, pips (seeds) to the number two in each of the five boxes of Ovarian initial surrounded by a sclerotized envelope (which recalls the core of a drupe), the set is itself surrounded by a thin pulp, which is the development of the lining of the ovary. Then a thin fibrous membrane marks the separation from the container which was considerably thickened to form the bulk of the fruit flesh. So that what we eat has been the nature of a Induver is the envelope of the fruit, the latter constituting the core.
