Size and density of cortical cells of ‘Royal Gala’ and ‘Scifresh’ at the fruitlet and mature stage. Cryo-scanning electron micrographs of fruitlet (A, C) and mature fruit (B, D) of ‘Royal Gala’ (A, B) and ‘Scifresh’ (C, D), and cortical density of cells at the mature fruit stage (E). Bars = 200 μm for all micrographs. Apples were matched for size at each stage of development. Values in (E) are the mean of 15 measurements ± SE.
