Effects of P deficiency on phosphate (Pi) accumulation and acid phosphatase (APase) activity in soybean. (a) Total P content of shoots, roots, and nodules. (b) Total Pi concentrations in shoots, roots, and nodules. (c) Soluble Pi concentrations in leaves, roots, and nodules. (d) Acid phosphatase activity of leaves, roots, and nodules. Data in the figure are mean of four replicates with standard error bars. Asterisks indicate significant difference between HP and LP treatments in the Student’s t-test (*: p < 0.05).
