Effects of Pi availability on stylo growth. a Root growth performance; b dry weight of shoots and roots; c total root length; d root surface area; e root volume. Uniform 7d-old stylo seedlings were transferred into nutrient solution with (+Pi) or without (-Pi) 250 μmol/L KH2PO4 additions for 0, 7, 10, 15 or 20 d. Quartile (box), maximum and minimum (whiskers) and outlying values (circles) are shown in boxplots. Each experiment included six biological replicates (n = 6). Error bars indicate standard error (SE). Asterisks represent significant differences between +Pi and -Pi treatments (P < 0.05). Bar = 3 cm
