Características das dimensões das fibras e análise do ângulo microfibrilar de Toona ciliata cultivada em diferentes localidades

Abstract

Fibers dimensions characteristics and microfibril angle analisys of Toona ciliata cultivated at different places. The objective of this work was to determine the fibers dimensions and to evaluate the microfibril angle of the wood of Australian cedar with 4 years of age, in the axial direction base–top, proceeding from the municipal districts of the Cana Verde, Campo Belo and Santo Antonio do Amparo, located in the region of the South of Minas Gerais. From the commercial height of each tree, a board with 5 m of length was removed, from this board it was taken samples in three positions: base, 50 and 100%. The anatomical elements were measured through image analysis. Concluded that: the correlation of the AMF with the wall and fire of fibers dimensions was positive and negative only interaction AMF with the fiber length in municipal districts of Cana Verde and in Santo Antonio do Amparo, was low. Top for municipal district did not have a definite standard of variation in the microfibril angle with the fibers dimensions in the axial direction from municipal district. The fibers dimensions presented similar characteristics of the eucalipto. Complementary studies are necessary for one better aiming of the use of the species.
