Polyphenol concentrations in grain, leaf, and callus tissues of mold-susceptible and mold-resistant sorghum cultivars uri icon


  • Thirteen cultivars differing in reaction to grain moulds (caused by a range of unspecialized fungi, including Curvularia lunata (Cochliobolus lunatus) and Fusarium multilforme (Gibberella fujikuroi)) showed differences in contents of polyphenols, including flavan-4-ols and proanthocyanidins. In particular, levels of flavan-4-ols in grain and leaf extracts (but not callus) of resistant cultivars were 2-3 times higher than those found in susceptible cultivars
