Fig. 3

Scatter plots obtained from two-block partial least squares (2B-PLS) analysis, with 95% confidence ellipses, illustrating the relationship between size (log centroid size) and symmetric component (a) or asymmetric component (b) of the leaf shape of Quercus aquifolioides WSP-HDM, Tibet lineages, and mixed individuals. The thin-plate spline deformation grids in a represent leaf shapes reflecting the negative (− shape) and positive (+ shape) extremes of the PLS axis for symmetric component
