Abstract

A case is presented where the Chapman-Richards growth function is suitable to describe growth for a certain period during the life of a stand of Eucalyptus grandis in South Africa. Toward the end of that period, diameter growth exhibited strong asymptotic properties. After marked competition mortality, the stand resumed growth beyond what had appeared to be an asymptotic level and the Chapman-Richards function could no longer be satisfactorily fitted. A generalized growth function developed by Schnute successfully tracked this renewed growth. The parametric relationships between the two models are established. For. Sci. 34(3):790-797.
