Fig. 2. Comparisons of nitrate uptake rate (NUR) among seedlings within each of six Kentucky bluegrass cultivars: (A) Blacksburg, (B) Barzan, (C) Conni, (D) Dawn, (E) Eclipse, (F) Gnome. The mean NUR for each seedling was based on 19 daily observations shown in Fig. 1. The LSD at P < 0.05 was shown as the last bar in each graph.
