Figure 2.

Total phenols (μg gallic acid equivalent (GAE)/g of fresh root) at 3 weeks in the roots of resistant wheat genotypes—CPI133872 (blue), GS50a (green), and QT8343 (red)—and susceptible wheat genotypes—Janz (black) and Gatcher (orange)—grown on agar in gnotobiotic conditions. The values are the means of three replicates. The bar marker indicates LSD = 84 (p = 0.05). The Pratylenchus thornei resistance rating of each wheat genotype is shown in parenthesis—R = resistant, MR = moderately resistant, S = susceptible, and VS = very susceptible.
