In the region of Ayotoxtla, in the state of Guerrero, the growth of four pine species was assessed: Pinus radiata, P. oaxacana, P. montezumae, and P. pseudostrobus. Using the site index models of stem analysis, current annual increment and mean annual increment for each dasometric variable were obtained. This served to adjust the models of site index using age:height ratios to obtain models for the prediction of volume in function of diameter at breast height (dap) and age and obtain models of volume growth, dap and total height in function of age. The Chapman-Richards model had the best fit in calculating site indexes of the different species. The volume predictor models obtained were combined variable for Pinus radiata, Australian for P. oaxacana, and modified Meyer for P. pseudostrobus. In the test of growth models in function of age, the Shumacher model showed broad representativity, except for dap in the species Pinus oaxacana and P. pseudostrobus, for which the best fit was that of the Chapman-Richards model.Keyworks: growth models, site index, volume table.
