E avaliado e simulado o crescimento de povoamentos jovens, equiâneos, monoespecificos e homogeneos de Pinus taeda L. utilizando a tecnica de simulacao Matrizes de Transicao. Os dados utilizados provem de medicoes realizadas em arvores individuais em 1993 e 1996 (6o e 9o anos), em um experimento de espacamentos em Pinus taeda L., instalado no municipio de Jaguariaiva - PR, na Fazenda Lageado, de propriedade da empresa Pisa Florestal. A construcao das matrizes de transicao a partir de observacoes diametricas obtidas de povoamentos de Pinus taeda em duas idades e factivel e permite obter simulacoes coerentes para um periodo igual ao intervalo entre estas idades. Ja a simulacao para intervalos de tempo maiores do que o periodo considerado para a construcao das matrizes de transicao e desaconselhavel, por se tratar de povoamentos jovens e nao estar disponivel, portanto, informacao do ciclo completo da dinâmica da floresta. Use of transition matrices in precocious growth evaluation and simulation of Pinus taeda L. stands Abstract The growth of young, even-aged, monospecific and homogeneous stands of Pinus taeda L. are evaluated and simulated with the Transition Matrix simulation technique. The used data was obtained from measurements over individual trees in 1993 and 1996 (6th and 9th years) in an spacing test of Pinus taeda L. at farm Fazenda Lageado in Jaguariaiva-PR, from the Pisa Florestal company. The transition matrixes construction from two diameter observations separated by a time interval are feasible and conduce to coherent simulations for a similar time interval that the used for the transition matrixes construction. Simulations for longer time intervals that the used for the transition matrixes construction are not recommended because the sampled stands are young and it is not disposable information about the complete dynamic cycle of the forest.
