apple fruit

An apple fruit consists of 2–5 carpels which are not fused with each other, but with the inner wall of the pitcher-shaped flower-axis. The floral-axis (base of the flower) of apple fruits enlarges during fruit maturity, becomes fleshy and then encloses the carpels which form the core of the apple-fruit. The pulp is developing from the floral-axis (base of the flower), while the carpels form the core (e. g. in Malus domestica – Apple, Pyrus communis – Pear, Sorbus aucuparia – White Beam and other Rosaceae – Rose family members).
