Definizione

Wax-like coating which covers the outer surface of the skin and renders the berry waterproof.1

Nota

Grape berries, like the fruits and leaves of most land plants, are covered by non-living layers of cuticle and epicuticular wax, which shield the underlying plant tissues from desiccation, infections, insect attack and injuries due to wind, physical abrasion, frost and radiation. 2
The leaf and fruit surface of higher plants are covered by the cuticle or cuticular membrane. Thus, the plant constitutes the interface between the plant tissue and the environment. From a structural point of view, the cuticle is formed by an insoluble polymer matrix of hydroxyfatty
acid esters called cutin. Associated with this biopolymer are waxes or soluble cuticular lipids; embedded within the matrix, intracuticular waxes or deposited on the outer surface of the plant cuticle, epicuticular waxes.3

Contesto

At the final stage of growth, the berry has a smooth, continuous and homogeneous cuticle with a thickness of 3 μm. 4
