Testing the potential significance of different scion/rootstock genotype combinations on the ecology of old cultivated olive trees in the southeast Mediterranean area

Table 3 Predicted direction of influence for the effects of environmental variables on the phenotypic traits of the investigated trees belonging to GG1 and GG2; model summaries are provided in Additional file 3

Positive and negative association is given by the coefficients of the most parsimonious model (Additional file 3) for the given trait as either positive (+ green cells), negative (− red cells) or zero (blank grey cells; when the variable was not present in the final model). Interaction between genotype combination and environmental effects is indicated by the differences between the two columns for a given environmental variable. For example, the effect of CaCO₃ on peroxide value is positive in GG1 but negative in GG2 due to the presence of an interaction term in the final model
