Phenolic compound contents in the resistant genotype PRA-R compared to the susceptible genotypes. Contents in PRA-R were expressed as percentage proportions (%) relative to the mean values for all three susceptible genotypes for all analysed time points. For 38 dpi, symptomatic (S) and non-symptomatic needles (NS) are shown. Increases are highlighted with shaded areas and significant changes compared to susceptible trees are indicated with green (increases) and red (decreases) compound names. Shown are astringin (astr), isorhapontin (isor), piceid, piceatannol (piceat), resveratrol (resv), shikimic acid (shik), picein, kaempferol (kaem), kaempferol 3-glucoside (k3g), kaempferol 3-rutinoside (k3r), kaempferol 7-glucoside (k7g), quercetin (quer), quercetin 3-glucoside (q3g), taxifolin (tax), gallocatechin (gall), and catechin (cat). Please note the different scaling at 38 dpi
