Total number of P. radiata seeds collected in eight plantations was 7100 from 71 trees. Out of these seeds, less than 1% (52 seeds from 12 trees) were infested with F. circinatum (mean of infested seeds = 0.73%, standard error ± 0.244%). The pathogen was present on the coat of all infested seeds and in some of them, F. circinatum was also infecting the gametophyte (mean percentage of infection 0.52 ± 0.219). In a small proportion, the embryo was also infected (0.10 ± 0.05). All seeds with an infected embryo had an infected gametophyte and seed coat as well (Figure 1).
