Table 1. Recovery of N. parvum was determined by culture, and fungal colonization of xylem fibers and rays was determined by light microscopy.

Each incubation period represents a separate set of plants inoculated at two-week intervals. Separate plants within each treatment—incubation period were used for recovery (six per treatment—incubation period) and microscopy (three per treatment—incubation period).
