Wood anatomical characteristics of native narror leaved ash (Fraxinus angustifolia vahl) taxa of Turkey and the effects of different growth environments on these characters

In this study, the wood and soil samples belonging to native Narrow Leaf Ash tree grown in Turkey were taken according to the location and elevation. The different growing conditions for the collected materials were divided into semi-arid, semi-arid-less-humid, semi-humid and moist areas based on the map created by the meteorological administration according to Thornthwaite precipitation activity index. On wood samples; measurements and counts were made for the features of vessel cells (tangential and radial diameters, numbers in 1 mm², lengths), features of ray (width, height, numbers in 1 mm, numbers in 1 mm²), features of fiber cells (lengths, widths and thickness of wall). Physical (ratio of sand, silt and clay) and chemical (pH, electrical conductivity, organic matter) features, type and available water capacities of soil were identified for the soil samples. By using vessel member features, "Vulnerability" ratio (vessel diameter divided by number of vessels per mm²) and "Mesomorphy" value ("Vulnerability" multiplied by vessel elements length) was calculated. Statistically analyzes performed with the data of wood and soil samples; wood anatomy features and the relationship between different growing conditions and altitude. As a result, it was determined that both the anatomical characteristics of the ash wood and the soil properties were statistically different in different ecological conditions.
