Abstract

In response to the challenge of harmonizing agricultural production with sustainable environmental management, setting up of agroforestry systems (AFSs) is an appealing alternative that combines crops and wood production with ecosystem services. In this context, Schizolobium parahyba var. amazonicum Huber × Ducke (paricá) has shown good silvicultural performance in AFSs. Nevertheless, the properties of its wood when grown in AFSs are not widely reported in the literature. The present study aimed to characterize paricá wood regarding its technological characteristics and industrial applications. Wood was obtained from a multi-stratified AFS in midwestern Rondônia state, northern Brazil. The AFS is composed of perennial crops and forest species cultivated in double rows with spacing of 5.0 m × 2.5 m. Experimental results showed paricá wood had low extractives content and density along with good dimensional stability. However, the wood’s mechanical performance was similar to that observed in material from pure plantations and pristine forests. Specific strength was similar to wood species with higher basic densities. Paricá wood reached the minimum requirements for structural uses and had suitable characteristics to be employed to produce engineered wood panels.
