Resumo(s)
The objective of the present work was the modeling height growth in the regeneration stage and diameter growth in juvenile stage of the cork oak species. The data used were obtained from measurements performed on permanent plots installed in pure cork oak stands, located on the municipalities of Coruche, Estremoz, Ponte de Sôr, Sines, Évora, Idanha-a-Nova and Castelo Branco. The stands were characterized for soil type, climate and stand variables. Two tree-level functions were adjusted: one for total height growth in the regeneration stage and other for the diameter prediction. In both cases the functions selected were the ones presenting best performance through comparison of several fitting and prediction ability statistics (precision and bias). The rule established for the definition of the regeneration and juvenile phases applied in the SUBER model, based on a combination of values of total height and diameter at breast height, was discussed based on the values presented in the data set of the present work.
