  1. LMF: leaf mass fraction; SMF: stem mass fraction, RMF: root mass fraction; DW: dry weight; SLA: specific leaf area; NSU: number of stem units; HON3: height at first production of axillary shoots; b, m: coefficients of the Gompertz function; HTOT: total height; SUR: Survival; NA: not available.
  2. h2: heritability; S.E. (h2): standard error of h2; MEAN: mean value of the population; CVA: coefficient of additive genetic variation.
  3. Heritability estimates are shown only when family effects were statistically significant.
