Crescimento em diâmetro de <i>Araucaria angustifolia</i> (Bertol.) Kuntze em função da idade, em três regiões do Rio Grande do Sul.

Abstract

O presente trabalho teve como objetivo estudar o crescimento em diâmetro em função da idade, de povoamentos naturais de Araucaria angustifolia (Bertol.) Kuntze, nas regiões fitogeográficas do Planalto Médio, Encosta Superior do Nordeste e Serra do Sudeste do Rio Grande do Sul. Para isso, utilizou-se a equação de crescimento de Backman, que se mostrou eficiente com aplicação de variáveis dummy, permitindo identificar diferenças no crescimento para as regiões estudadas, havendo a necessidade de equações separadas para cada local, o que permitiu minimizar os erros de estimativas. Os resultados obtidos demonstram que, em cada região, a espécie apresentou forma e crescimento diamétrico diferenciado. Na Serra do Sudeste, o incremento médio anual em diâmetro foi de 0,96 cm/ano aos 33 anos; no Planalto Médio, de 0,95 cm/ano aos 22 anos; e, na Encosta Superior do Nordeste, de 1,04 cm/ano aos 20 anos de idade, indicando um bom potencial de crescimento médio.
