Description

To examine the applicability of growth equations, the Mitscherlich, the Logistic, and the Gompertz equations were applied to the observed growth of diameter, height basal area and volume of 52 trees. This application showed that the best fit for all growth factors was achieved by the Gompertz. The Mitscherlich showed a good fit to the diameter growth and the height growth without a clear inflection. On the other hand, the applicability of the Logistic to the growth with a clear inflection was recognized. These results indicated that the consideration for the characteristics of growth equations wasa matter of great importance to the applications.
