Resistance and tolerance of ten carrot cultivars to the hawthorn-carrot aphid, Dysaphis crataegi Kalt., in Poland
Fig 5
Effects of hawthorn-carrot aphid (Dysaphis crataegi) foraging on the length (A, F), weight (B, G), and contents of sucrose (C, H), reducing sugars (D, I) and carotenoids (E, J) in the roots of the ten tested carrot cultivars. * Significant differences between the control mean and the mean in colonized plants based on the Student’s t test conducted separately for each cultivar (P<0.05).
