Heat map diagram of primary metabolites in the skin samples of sweet cherry cultivars. Metabolites divided into soluble sugars a, amino acids b, organic acids c, soluble alcohols d and other compounds e. Based on grand mean log2 an increase is depicted as red and a decrease is depicted as green (see color scale). Metabolites abundance were expressed as relative abundance compared to internal standard adonitol. Each metabolite represented by 20 sweet cherry skins in three biological replications.
