Wood growth rings, coloured X-ray. Growth rings in wood are exposed by cutting across a tree trunk or large branch. Each ring represents a period of growth in which the tree formed new wood. Each year the outer part of the wood, the living part, lays down a new layer. The older layer dries out and dies, forming the hard mass of wood in the core, the heart wood. Each ring corresponds to a single year and allows the age of the plant to be calculated. A ring varies in width according to the climate that year.
