The relationship between tree size (diameter at breast height [DBH] at 1.3 m) and the density of alive trees (number/per hectare) for outcrossed E. globulus (GLxGL) and E. ovata (OVxOV), open-pollinated E. globulus (GLop) and E. ovata (OVop), and selfed E. globulus (GLself) and E. ovata (OVself), as assessed from planting to 28 years of age. The fitted line shows the trajectory for each cross-type by species combination using log-transformed values of DBH
