Means (SE) of regions are based on population means, which in turn are based on seed family means. Different superscript letters indicate significant differences (α = 5%) among regions using Tukey's HSD tests and between treatments based on significance of the treatment factor in the generalized linear mixed-effect models (Table 1). WA – Western Alps; CSA – Central Swiss Alps; CAA – Central Austrian Alps; SEA – South-eastern Alps.
