Fig. 7

Effect of TiO2 NPs and different NaCl concentrations on seedling length vigor index (SLVI, a and b), shoot length stress index (SLSI, c and d) and root length stress index (RLSI, e and f) of two soybean varieties (35 and 22) respectively. Data represent means ± standard errors (error bars) of three biological replicates. Different letters indicate significant difference (p < 0·05), according to a Duncan multiple range test
