Fig. 1From: Root system traits impact early fire blight susceptibility in apple (Malus × domestica)Box plot showing distribution of root dry mass (g) in three disease severity classes observed in 45 grafted scion genotypes on ‘M.7’ rootstocks. The percent lesion length classes were defined as Resistant (0–20% average PLL), Intermediate (21–80% average PLL), and Susceptible (81–100% average PLL).
