Effect of NRE treatment on root biomass of different root classes under high-N (A) and low-N (B) conditions in growth chamber hydroponics study. Each column represents the mean of n=5 for each treatment. Error bars represent SEs, and columns with the same letter under the same root class were not significantly different at P≤0.05 according to Tukey’s test. ER, embryonic root; NR1, first whorl nodal root; NR2, second whorl nodal root; NR3, third whorl nodal root, NR4, fourth whorl nodal root; NR5, fifth whorl nodal root.
