The analysis morphometric of the leaf fibers of Astrocaryum murumuru var. murumuru Mart. demonstrated that the petiole's fibers had presented length and wall thickness superiors than the rachis and leaflets, with yours means varying of 1.266,09 µm to 3.270,56 µm and 5,56 µm to 10,67 µm, respectively. In relation the index of Runckel and flexibility's coefficient the petiole and rachis had gotten values considered favorable for its use in the paper industry and, the felting index it probably demonstrated that the fibers of these regions will present good crash resistance when submitted to the evaluations physical-mechanical. therefore, the results show the species is a alternative source of raw material to produce paper, but its necessary to do physical-mechanical resistance studies to consolidate this pre diagnostic.
