Figure 2. Necrosis length of Pinus pinaster seedlings caused by inoculation treatments.

Seedlings were derived from 10 maternal genotypes clonally replicated in two contrasting maternal environments, one favourable (open circles) and one unfavourable (black circles) for pine growth and reproduction, four weeks after inoculation with the Fusarium circinatum pathogen (Inoculated) or mock inoculation with distilled sterile water (Control) (N = 360). Least square means ± standard errors obtained from the mixed models excluding (A) and including (B) seed mass as a covariate are shown.
