From: Belgian endive-derived biostimulants promote shoot and root growth in vitro
P. esculentus root and shoot architecture stimulation upon treatment with water (control) or with two concentrations (10–3 and 10–2) of HO. Graphical representations showing the effect of HO on (a) root numbers, (b) root length, (c) shoot numbers (black arrowheads), and (d) shoot length. (e) Images of the mature explants at the concentrations tested including control. Data represent the average of two biological and ten technical replicates per bar. Error bars represent standard mean error (SEM). Asterisks indicate significant differences between control and treatment according to Dunnett’s multiple comparison test (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001).
