Abstract:	Two new taper models for stem profile (laper) were developed using q-exponential function. Five previously constructed models and two new q-exponenlia] taper models were compared io ihe observed values of diameter oulside bark and siem volume. Data used in this study came from stem analysis on 1,925 Scots pine trees. Results show that the q-cxponential segmented taper model was superior (o the Burkhart, Kozak. Lee, Sharma laper models in predicting diameter outside bark and stem volume. The results are implemented in the symbolic computational language MAPLE
