LIMA, Israel Luiz de et al. Radial variation of basic density and wood cells dimensions of Cariniana legalis (Mart.) O. Kuntze depending on the provenance. CERNE [online]. 2011, vol.17, n.4, pp.517-524. ISSN 0104-7760.

Provenance tests can provide information about the silvicultural behavior and wood quality for the exploration of variability and conservation of genetic material for future use. This study aims to investigate the effect of provenances on some wood properties of the Cariniana legalis. Seedlings of three provenances (Porto Ferreira, Piracicaba and Campinas) were planted in Luiz Antonio-SP using randomized block design with six replicates. After 26 years of planting, eighteen trees, six of eachprovenance, were felled. The properties studied were basic density and the cellular dimensions. The results revealed that the basic density, fiber length, fiber wall thickness, vessel element length, vessel diameter, uniseriate ray height and width were influenced by the provenances. A good positive relationship was found among the fiber length, fiber wall thickness, vessel element length; vessel diameter and multiseriate ray height with radial position and a negative relation between vessel frequency with the radial position.
