Crust

 

in plants, a complex of tissues on the surface of the stem and roots of woody plants, consisting of dead peridermal cells and parts of the bark. The crust forms as layers of periderm repeatedly form in the phloem. In the case of more or less concentric arrangement of peridermal layers, a ringed crust forms (as in mock orange and grapes); if the peridermal layers overlap, a scaly crust forms (as in oak). Depending on the nature of the depositing of crust, it falls from the surface of the tree in layers, ribbons, or scales. Crust usually forms late (in birch, pine, and oak when the tree is 25–35 years old); it protects the plant from excessive evaporation, sharp fluctuations of temperature, and other undesirable effects.
