Characteristics of the Norway spruce and European beech pure stands which serve as reference for revelation of mixing effects on the neighbouring mixed plots. Shown is (a) top height ho at age 100 and (b) periodic mean annual volume increment PAIV. The large rhombi indicate the species-specific mean values of ho (N. sp. 35.1 m; E. b. 29.9 m) and PAIV (N. sp. 14.7 m3 ha−1 y−1; E. b. 10.5 m3 ha−1 y−1).
