"Radial growth" refers to the process of growing outward from a central point or a central axis. It typically involves the expansion or thickening of a circular or spherical object. Full definition
Other Bristlecone Pine studies (Fritts, 1969; LaMarche, 1973; LaMarche and Stockton, 1974) have suggested that growth, especially radial growth of the stem, depends on reserves of stored food produced during earlier periods.
