Analysis of nematode developmental stages in roots of Peking and PI88788 (resistant) and Williams 82 (susceptible) assayed at 5, 10, and 15 dpi (days post-inoculation). Roots were dissected 5 (A), 10 (B), and 15 (C) dpi, and nematode developmental stages (juveniles, second stage (J2), J3, and J4) were analyzed. The number of J4 include cysts. Data (nematodes from 15 plants produced in three different biological experiments) are represented by the mean ± standard error. * indicates a statistically significant difference (p < 0.05).
