In most fruits, as they grow, cuticle is released only at the early stage and later it stops releasing cuticle material. Often the cuticle layer is strained, many a times reversibly, during the development of a fruit. However it’s different when it comes to an apple.Throughout fruit development, cuticle material is deposited as the area of the skin surface expands with no apparent buildup of reversible elastic strain. This is how the cuticle layer looks in a foldscope when the fruit is fully mature. This is only the outermost covering.
