Anatomical variation in Quercus obtusata (Fagaceae) wood
Wood of Quercus obtusata is described and the variation of nine quantitative wood characters is evaluated through tree height and diameter, elevation and 11 climatic parameters in four sites. Pearson correlation showed that only the narrow vessel element length is significantly correlated with tree...

| description | Wood of Quercus obtusata is described and the variation of nine quantitative wood characters is evaluated through tree height and diameter, elevation and 11 climatic parameters in four sites. Pearson correlation showed that only the narrow vessel element length is significantly correlated with tree height (rp = 0,70, p <0,02). The principal component analysis revealed that three components explain 76,46% of the total variation and ten variables are those with the highest loadings. Moreover, this analysis segregated the localities due to altitude and some climatic variables as for temperature and rainfall throughout the year, which have an effect on vessel elements length, as well as on fibres length and wall thickness. The driest locality, Arcos del Sitio, and in that of higher elevation, Santa Ana Jilotzingo, have the shortest vessel elements with wider diameter (561 µm and 552 µm respectively) than the most humid environment, Santa Catarina (621 µm). The fibres neither diminish in size with the elevation nor increase with tree height. The analyses suggest that the microclimatic parameters of each location need to be accounted when recommendations for Q. obtusata wood used as raw material or in reforestation programs are given. |

Se describen las características anatómicas de la madera de Quercus obtusata y se evalúa estadísticamente la variación anatómica de nueve caracteres cuantitativos de su madera en función de la altura y diámetro del tallo, de la altitud y de 11 parámetros climáticos en cuatro localidades. La correlación de Pearson mostró que sólo la longitud del elemento de vaso angosto se asocia significativamente con la altura del árbol (rp= 0,70, p< 0,02). El análisis de componentes principales reveló que en tres componentes se explica 76,46% de la variación total y diez variables son las más importantes. Este análisis segregó las poblaciones debido a la altitud y algunas variables climáticas, siendo la variación de la temperatura y la precipitación a lo largo del año, las que tuvieron un efecto sobre la longitud de los elementos de vaso, así como sobre la pared y longitud de la fibra. En la localidad más seca, Arcos del Sitio, y en la de mayor altitud, Santa Ana Jilotzingo, los elementos de vaso con mayor diámetro son más cortos (561 µm y 552 µm respectivamente) que los del ambiente más húmedo, Santa Catarina (621 µm). Las fibras no disminuyen su tamaño con la altitud ni lo aumentan con la talla de los individuos. Este análisis sugiere que se debe tomar en cuenta la procedencia microclimática de las poblaciones para hacer recomendaciones de uso de la madera de Q. obtusata o para planes de reforestación.
