Changes in acidity during fruit development. Total titrable acidity in juice extracts of selected varieties of mandarins (A), oranges (B) and lemons (C) during pulp development. Clemenules acidity profile (dotted line) is included in panels B and C as a reference. Vertical dashed lines separate the three phases of citrus fruit development: cell division (phase I), cell expansion (phase II) and ripening (phase III).
