Fig. 2

Relationship between root P concentration at final nursery sampling and root growth potential (RGP) of Holm oak (Q. ilex) measured as dry mass of new roots (mean ± SE) protruding the plug. Each dot represents averaged RGP of five seedlings from a tray over root P concentration of five composite roots from the same tray (n = 15 trays). Inset RGP (mean ± SE, n = 15 plants per treatment) of Holm oak as affected by fall fertilization (see Fig.1 for treatment descriptions). Asterisks on control bar indicate significance of the contrast that compares control mean with the average of all the other treatments means (P = 0.003)
