ABSTRACT:    This study aims to investigate the diametric structure of a seasonally dry tropical forest in Bahia and to select the best functions for the stand and species of greater importance. Two subsets were selected for fitting and validation from pre- and post-selective harvest inventories. Normal, Log-normal functions were tested; Gamma, Weibull 2P, and Weibull 3P. The best fits were selected using the Kolmogorov-Smirnov test for Akaike information criterion. Negative exponential curves and positive skewness best described the diameter distribution. This behavior was observed for the species with the highest IV and the stand. The Log-normal function best describes the diametric structure of Commiphora leptophioeeos, Manihot catingae, and Pataggonula  bahiensis. It is recommended to individually describe the diameter structures of Aspidosperma  pyrifolium, Pseudobombax simplicifolium, and population by the Weibull 3P function. The Normal, Gamma, and Weibull 2P functions did not present feasible predictions for frequencies of the diameter classes in all analyzed cases.

RESUMO:   Este estudo tem como objetivo investigar a estrutura diamétrica de uma floresta tropical sazonalmente seca na Bahia e selecionar as melhores funções para o povoamento e espécies de maior valor de importância. Dois subconjuntos foram selecionados para ajuste e validação a partir de inventários pré e pós-corte seletivo. Foram testadas as funções Normal, Log-normal; Gama; Weibull 2P e Weibull 3P. Os melhores ajustes foram selecionados pelo teste de Kolmogorov-Smirmov critério de informações de Akaike. A distribuição do diâmetro foi mais bem descrita por curvas exponenciais negativas e assimetria positiva. Esse comportamento foi observado tanto para as espécies de maior VI quanto para o povoamento. A função Log-normal descreve melhor a estrutura diamétrica das espécies Commiphora leptophioeeos, Manihot catingae e Pataggonula bahiensis. Recomenda-se  descrever  individualmente  as  estruturas  diamétricas  das  espécies  Aspidosperma  pyrifolium, Pseudobombax simplicifolium e povoamento pela função Weibull 3P. As funções Normal, Gamma e Weibull 2P não apresentaram predições factíveis para frequências das classes diamétricas em todos os casos analisados.
