The paper presents the results of the investigations carried out in the Turkey oak stands in the Oltenia Plain, whereby a statistically fundamental relation was established between the coefficient of expansion (F) of the stands and its main dendrometric characteristics (diameter - D and height - H), expressed by an equation of the form logF = a0 + a1logD + a2logH, whose coefficients are statistically significant. By demonstrating the joint influence of both dimensional characteristics (D and H) on the coefficient of expansion (F), the influence of the structure of the stands on their production was revealed, thus eliminating the error-generating hypothesis expressed by the identity FD = FH. Finally, for practical purposes, for the area of the study case, tables were developed to determine the coefficient of expansion (F) according to the two characteristics of the tree (D and H). By this way of determining the form factor (F) of the stands, substantial improvements are made to the precision of their volume determination by means of the general formula V = G x H x F.
