The different lowercase letters (a, b, c) indicate significant differences (p < 0.05) in the respective metabolite concentrations between Medicago species within the identical ontogenic stage and the different uppercase letters (A, B, C) in the column indicate significant differences (p < 0.05) in the respective compound concentrations among ontogenic stages within the identical legume accession nc, NC-data with metabolite concentration <LOQ were not included for computation.
