Fig. 1

Response of nitrogen and phosphorus concentrations in green and senesced leaves to canopy nitrogen addition (CN) and understory removal (UR) across two seasons. Data are presented as means ± SD, with four replicates. Within each of the four-bar groups (Green or Senesced treatment) values with a different letter are significantly different based on ANOVA with LSD (P < 0.05). The lower and upper cases represent green and senesced subplots, respectively. CK, control; UR, understory removal; CN, canopy nitrogen addition; CN × UR, canopy nitrogen addition plus understory removal. Main effects of CN, UR, leaf types (green vs senesced), season (S) and their interactions were evaluated with four-way ANOVA analyses. *P < 0.05; ***P < 0.001
