Table II
Results of the GLMs for the studied variables. WR stands for water regime, Pop stands for population, Fam (Pop) stands for family nested in population and C stands for the covariate initial height. RdGR (i − j) stands for relative diameter growth rate in the time interval i − j, RhGR (i − j) stands for relative height growth rate in the time interval i − j, RMF stands for root mass fraction, SMF stands for stem mass fraction, NMF stands for needle mass fraction. The degrees of freedom for each factor/covariate are given in brackets by the caption F-value. One star denotes p < 0.05, two stars denote p < 0.01 and three stars denote p < 0.001.
