Figure 2. Changes in root and shoot fresh weights in Brassica napus seedlings treated with nitrate-Glu for 5 d on agar plates. (A) Effect of increasing Glu concentration in 1 and 5mM nitrate treated seedlings on shoot fresh weight. (B) Effect of increasing Glu concentration in 1 and 5mM nitrate treated seedlings on the root fresh weight. (C) Effect of increasing Glu concentration in 1 and 5mM nitrate treated seedlings on root elongation. Values are the average (± SE) of four replicates of four seedlings each. Significant differences between control seedlings treated with 1 or 5mM nitrate and nitrate-Glu treated seedlings are given for *p < 0.05; **p < 0.01 (t test); ***p < 0.001 (t test).
