Flavonoid biosynthesis pathway and the differential metabolites of different petal regions in lily cultivar ‘Vivian’. a Flavonoid biosynthesis pathway in lily cultivar ‘Vivian’. The red dots represent the up-regulated metabolites, while the green dots represent the down-regulated metabolites in S3 compared to X. The width of pink and yellow represented the relative substance content of S3 and X, respectively. b The differential metabolites in lily cultivar ‘Vivian’. Each colored cell represents the average value of each metabolites
