Equations to characterize diameter at breast height growth of Pinus montezumae based on increment cores

A set of equations to characterize the growth and increments in diameter at breast height (DBH) as a function of age (A) for Pinus montezumae in Puebla, Mexico was generated. From radial increment cores collected in the Forest Management Unit 2103 “Teziutlan” 294 pairs of DBH-A observations were processed. Six growth models were fitted. The Hossfeld IV model was selected (R2adj of 0.8328, RMSE of 4.6649 cm and bias of 0.0525 cm). The technical turn was 27.5 years, which corresponds to a maximum mean annual increment of 0.86 cm year-1 and a DBH of 23.8 cm.
