Abstract
O presente trabalho objetivou estudar o desempenho das espécies castanha-do-brasil (Bertholetia excelsa) e cupiúba (Goupia glabra) e o ajuste de uma função de crescimento e uma equação para estimar o diâmetro de copa em um modelo de sistema agroflorestal - SAF implantado em 1995 no Campo Experimental Confiança, Cantá, Estado de Roraima. Foram medidas 71 árvores de castanheira e 50 de cupiúbas totalizando 121 árvores, sendo tomados o CAP (circunferência a 1,30 m do solo), altura total, altura de inserção da copa, diâmetro da copa e dados qualitativos como sobrevivência, qualidade do fuste, bifurcações e aspectos fitossanitários como doenças ou pragas. Das 71 árvores de castanheira avaliadas 20 (27,8%) produziram frutos. A cupiúba apresentou alta porcentagem de indivíduos com bifurcação (cerca de 87,5%). A análise estatística indicou a função de Backman como a de melhor ajuste para as espécies observadas e com base nas equações construídas para estimar o diâmetro da copa em função do DAP pode-se fazer inferências sobre o espaço vital necessário para atingir uma determinada dimensão. Ambas as espécies apresentaram potencial silvicultural para recuperação de áreas alteradas em sistemas agroflorestais ou plantios homogêneos.
The aim of this present work was to study the behavior of castanha-do-brasil (Bertholletia excelsa) and cupiúba (Goupia glabra) and also set a growing function and an equation for estimating the crown diameter in an agroforestry system model, installed in Confiança Experimental Station, Cantá, Roraima, Brazil, in 1995. We measured quantitative data, such as diameter basal height, total height, crown insertion height, crown diameter and qualitative data like survival, bole quality and phytosanitary aspects such as disease or pests. We analyzed the silvicultural behavior and estimated equation at the crown diameter in function of DBH, and adjusted a growing function for the cupiuba and castanha-do-brasil. Of the 71 castanha-do-brasil trees analyzed 20 (27,8%) producing fruits. The cupiúba showed high individual percentage of bifurcation (around 87,5%). The statistical analyses indicated the Backman function as the best adjusted for the observed species; and based on the equations for estimating crown diameter in function of DBH, we could make inferences about the necessary vital space for reaching determinated dimension. Both species have silvicultural potential for restored areas in agroforestry systems or homogeneous plantations.
