Araucaria angustifolia has economic and productive potential in southern Brazil, due to its high wood quality and seeds appreciated by humans and wild animals, besides playing an important role in the rehabilitation of degraded areas. Moreover, the species represents an opportunity of higher incomes for small farmers through the establishment of plantations in small lots managed for timber production. However restrictive environmental laws, and little knowledge about the silviculture of the species has led to a lack of interest in planting and in developing new researches on A. angustifolia. So the objective of this research was to better understand the outcomes of management systems used in A. angustifolia plantations and to evaluate the feasibility of establishing araucaria plantations on small farms. For this purpose, we carried out an inventory in an 8-year-old, 0.92 ha araucaria plantation, with a spacing of 3 x 3 m, in Rio Negro, Paraná, Brazil. Based on the results, we used the SisAraucaria software to simulate thinning regimes, varying in age and type of thinning (only selective, only systematic or both), and clear cut at age 25. The regimes with two selective thinning episodes were more productive than those with only one or no thinning. The best economic return was obtained with the regime that included thinning at 10 and 20 years, with the first removing 80 % of the trees and the second 20 % of the trees. We conclude that the plantation model evaluated may be feasible if the appropriate thinning regime is applied.

O capoeiro (Colubrina glandulosa), pertencente à Família Rhamnaceae, apresenta ocorrência do Sul ao Norte do Brasil, podendo ainda ser conhecido como sobraji, saguaraji, falso-pau-brasil, sobrasil, guaxumbo, jucuruju, sábia-da-mata ou caçoca. A madeira é empregada na construção naval ou na fabricação de estacas, postes, mourões e também na confecção de móveis, devido sua resistência e cores róseo-forte-alaranjadas, proporcionando superfícies lisa e lustrosa. O objetivo deste trabalho foi descrever aspectos da anatomia das folhas de Colubrina glandulosa. |
