Stylo growth under different P levels. a Growth performance of stylo. b Plant height. c Leaf number. 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 standard error (SE). Different letters indicate significant differences among P treatments at P<0.05. Bar=5 cm
