  1. For the various terms, the unadjusted probabilities are shown and bolded when significant following Bonferroni adjustment (p < 0.05). The change that occurred in the different compounds following treatment (inducibility) is shown, where negative values (−) indicate reduction in the treated samples relative to the control and positive values indicate increase in the compounds relative to the control. The unadjusted p-values for the likelihood ratio test (LRT) associated with the significance of the random terms - differential inducibility (tree × treatment), family (specific combining ability, SCA) and tree (additive genetic variation) - are shown. The narrow-sense heritability and standard error (se) and the genetic correlation plus standard error (se) of the individual chemical compound with bark stripping and height are also included. The unadjusted p-value for the LRT test from zero are indicated for the genetic correlations (se) of the chemical compounds with bark stripping. For the correlation with height, only compounds that significantly correlated with bark stripping after Bonferroni adjustment were tested and unadjusted p- values are indicated in Table 2. The GC-MS components (monoterpenoids, sesquiterpenoids, GC-MS diterpenoids and phenolics) are expressed as micrograms of heptadecane equivalents (HE) per gram of dry weight of the sample (µg HE/g dw) and the LC-MS analytes (LC-MS diterpenoids and fatty acids) are expressed as micrograms of nonadecanoic acid equivalents (NE) per gram of dry weight of the sample (µg NE/g dw). Sugars are expressed in µg/g dw. Unknown indicates a compound that could not be identified. All compounds were given a unique identifier (ID) for ease of identification following Supplementary Table 1.
