Relationship between tree diameter at breast height (DBH) and the probability of a tree being assigned to Q. liaotungensis in populations NA (a) and Dlw (b). The dashed lines indicate the cut-off value of 0.9. Scatter points above the 0.9 dashed line represent Q. liaotungensis trees, scatter points beneath the 0.1 dashed line represent Q. mongolica trees, and scatter points between the two lines represent the hybrid trees
