Comparison of root surface areas and normalized nitrogen uptake rate in HHZ and 9,311. Total root surface area (a), root active uptake surface area (b) and active-to-total root surface area ratio (c) at 10, 25, 40 and 50 DAG. Plant NO3− uptake rate (d), NH4+ uptake rate (e) and total nitrogen uptake rate (f) on an active uptake area basis at 10, 25, 40 and 50 DAG. Plant NO3− uptake rate (g), NH4+ uptake rate (h) and total nitrogen uptake rate (i) on a root dry weight basis at 10, 25, 40 and 50 DAG. Data presented are mean values with s.d. (n = 5). **P < 0.01 (Student’s t-test).
