Mass-based N concentrations (mg g−1 DW) and leaf or stem mass per area (LMA and SMA, g DW m−2) of leaves and current-year stems of Fagus sylvatica L. in each N treatment (T1, T2, and T3). Data are means ±1 SE with n = 3. For each organ (leaves or stems), letters (a, b, and c) indicate significant differences between N treatments.
|N concentration||LMA||N concentration||SMA|
|T1||10.2 ± 0.13a||67.4 ± 0.76a||5.67 ± 0.20a||276.7 ± 7.90a|
|T2||17.2 ± 0.79b||72.1 ± 3.74a||10.1 ± 1.05b||307.9 ± 34.5a|
|T3||14.1 ± 1.27c||70.9 ± 3.07a||8.00 ± 0.81ab||294.7 ± 8.53a|
