Figure 12.

The distribution of the identified metabolite classes across the respective cultivars (Overberg, Pallinup, Dunnart, Magnifico and SWK001). This figure summarises cultivar-related differences due to underlying metabolic profiles of both leaves and roots. Each pie chart illustrates where a greater number of discriminatory metabolites were identified for each class across the cultivars. (A) Phenolic acids: discriminatory for the ‘SWK001’ and ‘Overberg’ cultivars. (B) Saponins (avenacoside A and avenacin A-1): discriminatory for ‘SWK001’ and ‘Dunnart’. (C) Flavonoids: discriminatory for ‘Magnifico’ and ‘Overberg’. (D) Fatty acids: discriminatory for ‘Pallinup’.
