Abstract

LONGUI, Eduardo Luiz et al. Characterization of wood and radial variation of Pittosporum undulatum Vent. - (pau-incenso). Hoehnea [online]. 2011, vol.38, n.1, pp.37-50. ISSN 2236-8906.  https://doi.org/10.1590/S2236-89062011000100004.

We studied the wood Pittosporum undulatum in Alberto Löfgren State Park, aiming to make its characterization, to investigate the radial variation of the anatomy and basic density and your relations and discuss the results in an ecological context. We utilized the standard methods to anatomy and wood density. The anatomical features corroborate the described for the genus, highlighting the presence of layer growth, not mentioned in the literature. The fibers diameter showed no radial variation, the other anatomical features, besides the density and vulnerability, mesomorphic and vessel grouping indexes increased toward the bark. There are positive relations between basic density and fiber wall thickness. The ecological analysis of the wood indicated that P. undulatum, investing more in security than in efficiency in the xylem water transport, since the values of ecological indexes are related to plants adapted to conditions of lower water availability.

Keywords : basic density; Pittosporaceae; Pittosporum undulatum; radial variation; wood anatomy.
