Figure 2:

Trial one Globodera pallida progeny cysts, remaining encysted eggs recovered from cyst bags, viability of remaining encysted eggs, viable remaining encysted eggs, and determined host status for G_ pallida_ Data presented are means of six replicates_ Significant differences are denoted by different letters in the columns based on least squares means at α = 0_05_
