Variations in quantitative vessel element characters of Juglans regia L. wood were studied in relation to altitude and growthring width. Multiple regression analysis using altitude and growth-ring width as independent variables were performed. Significant correlations were obtained for tangential vessel and radial vessel diameter (p¿0.001), vulnerability ratio and xeromorphy ratio (p¿0.01), and for the number of vessels per group (p¿0.05). Vessel frequency is not correlated with independent variables. Non-anatomical factors (altitude and growth-ring width) explain 40.4-80.4% of variation for dependent variables.

Palabras clave: Juglans regia, altitude, ecology, growth-rings, wood anatomy.
