Abstract:

The relationships between components of tree and crown structure were examined in even-aged stands of E. obliqua. The primary branch was stable, in that the relationships between branch length, diameter, projection, and stem diameter below the branch are fixed for the species and unaltered by the environment. By introducing an expression for crown asymmetry, tree and crown structure were defined by one set of measurements consisting of breast height diameter, total height, bole height, crown length, crown width, and stem diameter at the base of the live crown. A simple analysis of stem taper was used to develop general models describing tree and crown structure, independent of age, site quality, and stand density. These models are used to examine the influence of stand density on crown width. Forest Sci. 16:321-328.
