We investigated the relationships between various soil characteristics and anatomical wood attributes of Quercus pontica C. Koch. Wood and soil samples were collected from Rize-Ikizdere-Cimil and Rize-Findikli, Turkey, where Q. pontica is widely distributed. The soil samples were analyzed for particle size distribution (sand, silt, and clay content), pH, organic matter, field capacity (moisture equivalent), wilting point, and available water capacity (AWC). Wood samples were obtained alone, with soil samples. To determine fiber characteristics, fibers were prepared using Schultze's method and measured under a microscope. We found significant correlations between wood anatomical features and soil characteristics. Altitude was 2 positively correlated with the number of vessels per mm (r=0.98, p < 0.01) and tracheld fiber wall thickness (r=0.36, p < 0.05). Altitude was negatively correlated with the length of vessel members (r=-0.83, p < 0.01), the radial diameter of vessel elements in latewood (r=-0.89, p < 0.01), the tanuential diameter of vessel elements in latewood (r= -0.96, p < 0.01), the height of uniseriate rays (r=-0.68, p < 0.01), and the number of uniseriate rays per mm (r=-0.89, p < 0.0 1). AWC was negatively correlated with the number of vessels per mm 2 (r=-0.74, p < 0.01). Furthermore, vessel element length (r=0.63), radial diameter of vessel elements in latewood (r=0.68), tangential diameter of vessel elements in latewood (r=0.73), height of uniseriate rays (r=0.68), and number of uniseriate rays per mm (r=0.53) were positively correlated with AWC (p < 0.01).
