CONICITY AND YIELD FOR LUMBER FROM COMMERCIAL SPECIES FROM THE AMAZON
Santos,Misael Freitas dos; Gama,João Ricardo Vasconcellos; Figueiredo Filho,Afonso; Costa,Daniele Lima da; Retslaff,Fabiane Aparecida de SouzaABSTRACT Stem conicity and the sawing pattern, besides the presence of hollows and sapwood, are among the principal factors that are responsible for the low yield of lumber from harvested wood in the Amazon. Therefore, the objective of this study was to analyze of logs and stem conicity, and its effect on yield of sawn wood from the species Handroanthus impetiginosus (Mart. ex DC.)
