| 520 | _aA variable-form taper equation was developed for Pinus oocarpa Schiede in central Honduras. The model predicts tree profile as a function of total height, diameter at breast height, and relative height with a continuous function using a changing exponent to compensate for the form of different tree sections. The proposed five parameter model predicts underbark diameters with a standard error of 1.4 cm. The point where the taper curve changes from neiloid to paraboloid form, the inflection point, was assumed to occur at 25 per cent of total height. For the data used, no changes in the predictive ability of the model were observed with different location point | ||
