Time course of symptoms progression in Pinus radiata seedlings non-inoculated (C) or inoculated with Fusarium circinatum (FC), P. xcambivora (PC), P. parvispora (PP), F. circinatum ∗ P. xcambivora (FC × PC) and F. circinatum ∗ P. parvispora (FC × PP). Symptom severity was expressed as mean value of disease index (D.I.) at 7, 30, and 60 days post-inoculation (dpi). Images show the type of symptoms at each time interval post-inoculation. At each time interval, values sharing the same letters are not significantly different according to Tukey’s honestly significant difference (HSD) test (p ≤ 0.05).
