The objective of this study was to evaluate the growth tendencies of the stand variables and evaluate alternatives to construct site index curves for teak (Tectona grandis) in stands located in the Tangará da Serra, Mato Grosso state. For this purpose, data from 50 permanent plots with a minimum of four successive measurements were used. The tendencies of growth in height, diameter, basal area and volume were analyzed by means of the regression method, using the Chapman-Richards model. Two methods of construction of site index curves, with different models, were evaluated. The results of the analysis showed that Chapman-Richards model adjusted well to the observed data, describing the growth tendencies of the stand variables. The best alternative for the construction of site index curves was the guide-curve method, using the Chapman-Richards model.
