Fourteen-day-old stylo seedlings were subjected to 0, 100 and 250 μM KH₂PO₄ as low (Pi deprivation), moderate and high P supply treatments for 21 d, respectively. Each bar represents the mean of three independent replicates with SE. Different letters indicate significant differences among P treatments at P<0.05
