【 摘 要 】

The aim of the research was to evaluate the effect of the attack Leptocybe invasa in dendrometric variables and wood properties of two clones of eucalyptus (Eucalyptus urophylla and Eucalyptus tereticornis), grown in the municipalities of Imperatriz (state of Maranhão) and Darcinopolis (state of Tocantins), Brazil, for Kraft pulping. Data were collected 10 trees for each clone, the 3-year-old attacked by L. invasa. The diagnosed was based on formation of large guts all over the glass, and emergency hole (closing the loop). The results were confirmed by the variation of the characteristics of species assessed relative to their total height, diameter, volume of bark, vessel frequency, fiber size, radial density profile vessel frequency, fiber size, radial density profile, and ash content. Host trees obtained alterations in dendrometric variables, content of pentosans and wood ashes for both genetic materials, not being observed variations in specific gravity, and size of vessels and fibers, as well as the contents of lignin and wood extractives.
