a) Picture of 7 days-old Plantago ovata seedlings b) Dry biomass c) Shoot length d) Root length when treated with increasing Se concentrations (Control, 10 µM, 50 µM, 100 µM and 500 µM). Verticals bars represent the mean ± SE of mean. Different letters indicate statistically significant differences between means of each treatment group (Tukey’s HSD multiple comparison at p ≤ 0.05)
