Figure 9.

Masses of total N (A), predefoliation N (B), and postdefoliation N (C) in regrowing tillers of perennial ryegrass and in its component zones during the first 8 d of regrowth after severe defoliation: IM-AE, EX-AE, EN-FE, EX-FE, and TB. Leaves that had stopped to expand before defoliation are not included, because they did not form part of the regrowing tiller as defined here. For definition and designation of zones, see the legends for Figures 1 and 2. Vertical bars indicate ±2 se (n = 16).
