- MODELING Tectona grandis TREE AND STAND GROWTH USING STEM ANALYSIS AND PERMANENT PLOT DATA Daniel Menezes de Novaes Ana Carolina de Albuquerque Santos Carlos Pedro Boechat Soares Haroldo Nogueira de Paiva Geraldo Gonçalves dos Reis Marco Antônio Monte Flávio Siqueira Davila Helio Garcia Leite Agrociencias Site index Validation Grouping data The purpose of this study was to evaluate the efficiency of using total and partial analysis data of the trunk of Tectona grandis trees and of permanent plots, for the construction of site index curves and growth and production modeling, at the level of individual trees and of the settlement. Data were collected in settlements located in the State of Mato Grosso, with ages ranging from 2 to 10 years at the time of tree logging for trunk analysis. At that time, 40 permanent plots were installed, that were measured in the five subsequent years. Trunk analysis data obtained from those plots were used for validation of a variable density model. This model estimated the production with accuracy and consistency. Then, data from permanent plots were added to those of trunk analysis and the model was readjusted. It can be concluded that the trunk analysis of Tectona grandis trees is an efficient alternative of data collection for growth and production studies. The possibility of grouping past data, obtained by trunk analysis, with permanent plots, for growth modeling purposes, was also confirmed. Finally, the efficiency of trunk analysis data for growth modeling at a level of individual trees was evaluated and confirmed. 2017 artículo científico 0100-6762 https://www.redalyc.org/articulo.oa?id=48853636003 en http://www.redalyc.org/revista.oa?id=488 Revista Árvore application/pdf Universidade Federal de Viçosa Revista Árvore (Brasil) Num.5 Vol.41
