Leaf mass per area (LMA), mean area of a leaf (LA), leaf density (D) and leaf thickness (T) per treatment (control, C; winter resprouts, RW; summer resprouts, RS) in winter and summer. Values are mean ±SE of 30 replicates. Significant differences (p ≤ 0.05) are indicated by different letters (treatment (a, b, c); season (A, B)).
