a Liquid chromatography chromatograms (520 nm) of anthocyanin extracts from new leaves of the ornamental kale DH line ‘05-DH-65’. Horizontal axis shows retention time (min); vertical axis shows the strength of the chromatographic peak response intensity. The compound name is provided for each peak. b Total anthocyanins content in new and mature leaves of the DH lines ‘05-DH-65’ and ‘06-DH-71’
