Genotype-by-environment interactions and the dynamic relationship between tree vitality and height in northern Pinus sylvestris
Tree health and growth rate must both be considered in Scots pine breeding for harsh areas such as northern Sweden. Univariate (UV) and multivariate (MV) multi-environment trial (MET) analyses of tree vitality (a measure of tree health) and height (a measure of growth rate) were conducted for four s...

Tree health and growth rate must both be considered in Scots pine breeding for harsh areas such as northern Sweden.
