Fig. 7From: Potential of green synthesized titanium dioxide nanoparticles for enhancing seedling emergence, vigor and tolerance indices and DPPH free radical scavenging in two varieties of soybean under salinity stressEffect 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 testBack to article page
