Fig. 1 Effects of nitrogen (N):phosphorus (P) level on root and aboveground biomass and root/shoot ratio of Glycyrrhiza uralensis (mean ± SE, n = 5). N10P1, N10P2, N10P4, N10P8, N10P16, and N10P32 represent all pots treated with 10.0 g·m-2·a-1 amount of N but with different amounts of P: 1.0, 2.0, 4.0, 8.0, 16.0, and 32.0 g·m-2·a-1, respectively. Different lowercase letters indicate significant difference (p < 0.05) between indices within N:P levels. The same lowercase letters indicate insignificant differences (p > 0.05).
