ABSTRACT This study was carried out in the pure oriental beech forests of Yenice-Kızılkay in the Western Black Sea Region of Turkey, where the changes in the number of side roots and the changes in the height and diameter of the beech trees were examined in three different soil depth gradients. The root profiling was opened underneath beech trees, which were marked for cutting due to road construction studies and in 6 different aspects (north, south, northeast, northwest, southeast and southwest) in the 42 and 43 number divisions. In these root profiles, the cross-sectional surfaces of the side roots were counted and root lengths were measured at 3 different soil depth levels (10-30 cm, 31-50 cm and 51-80 cm) using 2x2m laths. In order to realize these side-root counts and measurements, studies were carried out on root profiles that were opened under 5 trees at each different aspect. In this context, a total of 30 trees in the root zone opened in the root profile, all the work continued. On the other hand, the height (H) and diameter (DBH) measurements were made on 5 sample trees examined in each aspect and these values were used to make comparisons in statistical analyses. The data obtained from the measurements made on these sample trees and root profiles opened on the of these sample trees were subjected to one-way analysis of variance (One Way ANOVA) according to the factors of depth and depth of view by SPSS 22.0 statistical programme. In this context, it has been determined that the mean number of side-root and length of side-root occurred differences significantly from 95% and 99%. According to the results obtained from the Duncan Range Test, the mean number of side roots and mean length of side root of the sample trees in northeast and northwest aspects were found to be higher in the first group. In the study, it was investigated how the mean number of side roots and the mean length of side roots change with respect to the soil depth ranges. As a result of the one-way ANOVA analysis, it was determined that the mean number of side roots and length were significantly different from 99.9% confidence level according to soil depth level. According to the Duncan Range test results conducted at 95% confidence level, it was determined that the first soil depth level covering the depth range of 10-30 cm in terms of both the mean number of side roots and the mean side root length was in the first group. In this research, a multiple correlation analysis was performed to determine the relationship and effect level between all the variables for which measurements and determinations were made. According to the results obtained from the multiple correlation analysis it is found that there are relations between different variables, different trust levels and different effects. Accordingly, an effective relationship was found between the NSR and the ASP variables at 95% confidence level in the positive direction (0.229*). On the other hand, between ASP and H (-0.280**), there were effective relations between NSR and SDG (-0.722**), between LSR and SDG (-0.669**), and between LSR and NSR (-0.789**) with 99% confidence level and negative direction. However, significant correlations were found between DBH and NSR (0.336**), between DBH and LSR (0.389**), between H and LSR (0.361**), and between H and DBH (0.906**) at 99% confidence. According to these results, both NSR and LSR variables and the DBH and H variables were found to have a 99% confidence level and an effective positive correlation. According to this, as NSR and LSR increase, the growth of height and diameter of mature oriental beech trees found in the sample areas is increasing.
