Fig 4. The effects of experimental treatments on plant nutrient concentrations.

Fig 4

The left hand side indicates the interaction of nursery fertilization (Low and High) and excision treatments (Nil, Slight, Intermediate, and Extreme) on root N concentration (A), stem P concentration (B) and root K concentration (C) (mean ± SE) of Quercus variabilis container seedlings after the first growing season. The right hand side indicate the main effects of nursery fertilization and excision treatments on stem N concentration (D), root P concentration (E) and stem K concentration (F) (mean ± SE) of Quercus variabilis container seedlings. Bars marked with different letters differ statistically within each main effect according to Duncan`s test α = 0.05.
