Effects of phosphate and nitrate availability on root morphology in wild-type rice seedlings. (A, B) Seedlings grown for 2 weeks in hydroponic media containing varying concentrations of phosphate (A) and nitrate (B). (C–E) Length of seminal root (C), lateral root (LR) length (D), and LR density (E) with containing varying concentrations of phosphate and nitrate. Red arrows indicate the four treatments for further study. Data are mean±SE. Different letters indicate significant differences (P<0.05, ANOVA) (this figure is available in colour at JXB online).
