Fig. 4. Effects of nitrogen addition, tree species and their interaction on photosynthetic nitrogen efficiency (PNUE)(A), length (B) and biomass (C) of the current-year branch of the two tree species, and effect of nitrogen addition on single seed mass (D) of Quercus wutaishanica (mean ± SD). Different lowercase letters indicate significant difference (p ＜ 0.05).
