Morphology of maize seedlings under LN and NN conditions. A Phenotype characteristics of maize seedlings at 7 d under LN and NN conditions. Bars = 10 cm. B Representative root architecture system at 7 d under LN and NN conditions. Bars = 10 cm. C The ratio of root to shoot in maize seedlings at 3 and 5 d after LN treatment. D The PR length in maize seedlings at 1, 3, and 5 d after LN treatment. E Distribution of LRP in maize seedlings at 5 d after LN treatment. Bars = 3 mm. F-G The LRP number F and density G in maize seedlings at 1, 3, and 5 d after LN treatment. Values with error bars represent mean ± SD (n = 8). The asterisks indicated significant differences between different treatments according to a Student's t test. **, P ≤ 0.01. PR, primary root; LRP, lateral root primordia; LN, low NO3–; NN, normal NO3–
