Abstract

The total antioxidant activity (TAA), total contents of polyphenols (TPC), phenolic acids (TPA) and tocols (TTC) were determined in the grain of 5 oat cultivars of Czech origin grown under organic and conventional cropping systems in two-year experiments (2018 and 2019). The TPC ranged from 772.9 mg/kg DM (dry matter) (hulled oat cv. Seldon) to 890.6 mg/kg (naked oat cv. Patrik); the TPA from 261.6 mg/kg (cv. Seldon) to 479.0 mg/kg (cv. Patrik); the TTC from 110.9 mg/kg (hulled oat cv. Korok) to 126.5 mg/kg (cv. Seldon). The TAA ranged from 427.1 mg/kg (cv. Korok) to 474.9 mg/kg (cv. Seldon). Besides the effect of the cultivar, the TAA and antioxidant contents were significantly affected also by year (weather conditions); higher values were observed in the drier and warmer the year 2019. The effect of the cropping system was statistically insignificant.
