The effects of foliar zinc application on grain antioxidant traits in some winter durum wheat cultivars at different growth stages

Abstract

This study was aimed to investigate the grain antioxidant activity (DPPH. and ABTS.+ radical scavenging activities and cuprac reducing capacity), contents of total phenolic compounds, flavonoid and total antioxidant capacity of five winter durum wheat cultivars under the foliar application of 0.2% of zinc (ZnSO4.7H2O) at different growth stages of grain filling (milky or dough ripeness). The study was carried out in randomized blocks according to the split plot design with three replications in the cultivars of Ç.1252, Eminbey, Kızıltan-91, Meram-2002 and Selçuklu-97.
