Scatter plot of the PCA for the P. coccineus leaves/shoots (A) and roots (B) for the second and third axes for physiological parameters, for example, shoot/root fresh weight (FW), root length, Chl a/b ratio, concentration of chlorophyll a (Chl a), Chl b, carotenoids (Car), Chl (a + b), C, N, C/N, P, K, Fe, Mn, Mo, Zn, Cu, flavonoids (FLAVO), phenolics (TPC), allantoin (ALLA), tartrate, malate, citrate, succinate; activity of SOD, CAT, APX, GPX, PAL, TAL, and GLU; and antioxidant potential (ABTS and DPPH tests). Abbreviations: J0 = without methyl jasmonate (J); J1 = with 1 µM of J; J10 = with 10 µM of J; −Cu = without Cu; +Cu = with 50 µM Cu; NI − S17 = no inoculation with the S17 isolate; I + S17 = inoculation with the S17 isolate.
