| contents | Relationships between anatomical features and intra-ring wood density profiles in Gmelina arborea applying x-ray densitometry Róger Moya Roque Mario Tomazelo-Filho Agrociencias tree ring wood anatomy wood density Gmelina arborea Four annual tree-rings (2 of juvenile wood and 2 of mature wood) were sampled from fast-growth plantations ofGmelina arborea in two climatic conditions (dry and wet tropical) in Costa Rica. Each annual tree-ring was divided in equal parts ina radial direction. For each part, X-ray density as well as vessel percentage, length and width fiber, cell wall thickness and lumendiameter were measured. Wood density and profile patterns of cell dimension demonstrated inconsistency between juvenile andmature wood and climatic conditions. The Pearson correlation matrix showed that intra-ring wood density was positively correlatedwith the cell wall thickness and negatively correlated with vessel percentage, fiber length, lumen diameter and width. The forwardstepwise regressions determined that: (i) intra-ring wood density variation could be predicted from 76 to 96% for anatomicalvariation; (ii) cell wall thickness was the most important anatomical feature to produce intra-ring wood density variation and (iii) thevessel percentage, fiber length, lumen diameter and width were the second most statically significant characteristics to intra-ring wooddensity, however, with low participation of the determination coefficient of stepwise regressions. 2007 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74413406 en http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.4 Vol.13 |
