YAMAN, Barbaros. Variation in quantitative vessel element features of Juglans regia wood in the western black sea region of Turkey. Agrociencia [online]. 2008, vol.42, n.3, pp.357-365. ISSN 2521-9766.

Variations in quantitative vessel element characters of Juglans regia L. wood were studied in relation to altitude and growth-ring 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.
