Fig. 2From: Physiological responses and transcriptomic changes reveal the mechanisms underlying adaptation of Stylosanthes guianensis to phosphorus deficiencyPlant dry weight and P concentration of stylo at different P treatments. a Shoot dry weight. b Root dry weight. c P concentration in shoot. d P concentration in root. 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<0.05Back to article page
