Table 3 Parameters and properties of a linear mixed model (Eq. 7) used to explain the above-ground biomass (AGB) of Pericopsis elata saplings, 41 months after transplantation, according to local competition (C, considering a 2nd order polynomial of C1/2), inbreeding (selfed or outcrossed) and the interaction between these explanatory variables.
