Table I

Mean biomass and P content of the seedling components (shoot, root and total, n = 5). Different letters indicate significant differences between the two treatments for the same harvest period. Different numbers indicate significant differences between harvest periods for the same treatment (P < 0.05). For the whole seedling (total), values in bold indicate significant differences from the initial value (0 d).
