Table 2.

Total flavonoids (FLAVO), total phenolic compounds (TPC), and antioxidant capacity (AC) determined using ABTS (2-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) in the Phaseolus coccineus leaves and roots. Data are means ± SD (n = 3). Values in each column followed by the same letter are not significantly different (p < 0.05; Tukey’s test). 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; FW = fresh weight.
