Arabidopsis shoot architecture stimulation upon treatment with different concentrations of fractions from HO. Graphical representations showing the effects of the organic fractions (a) and aqueous fractions (b) on leaf area. Data represent the average of three–four biological and ten technical replicates per bar (30–40 seedlings in total, 10 per replicate). Error bars represent standard mean error (SEM). Asterisks indicate significant differences (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001) between negative control (Ctrl) and treatments (concentrations) in respective groups (fractions) according to Tukey’s multiple comparison test. LA leaf area, F1–F8 fractions 1–8 denoted by different colors.
