(A) Total ferric reducing antioxidant power (FRAP) activity and phenolic content for Carrot. Wilcoxon One Way Analysis assessed variety differences (standard error bars with P < 0.05). Capital letters indicate significant differences between FRAP content and lowercase letters indicate significant differences between phenolic content. (A) x-axis break occurs between 150 and 200. (B,C) Represent Box whisker of FRAP and Phenolic distributions. Box boundaries represent quartiles, the thick line in the box is the median and the whiskers represent the samples minimum and maximum. Carrot cultivars include Bolero (n = 44), Mokum (n = 21), Romance (n = 17), Rothlid (n = 7), and Yaya (n = 12).
