FIGURE 6

Maximal PSII photochemical efficiency (Fv/Fm), PSII quantum yield (QY), linear electron transport rate (ETR), and non-photochemical quenching (NPQ) in control and inoculated plants of soybean cv. ‘PR91M10’ grown in closed-loop hydroponics, throughout the developmental cycle: flowering (44 DAS), fruit setting (57 DAS) and pod filling (84 DAS). (Mean ± standard error; n = 18). Within each date, different letters indicate significant differences at P < 0.05.
