Summary of the repeated measures mixed model for constitutive and methyl-jasmonate (MJ) induced allocation of chemical defenses (non-volatile resin and total phenolics) to two tissues (stem and needles) across three parts of the plants (basal, middle and apical upper part) in six P. radiata open-pollinated families. Significant P values (P<0.05) are typed in bold.
