“…In our study, a positive correlation occurred between grain Zn content and grain yield (r = 0.419), grain bulk density (r = 0.422), total gliadins (r = 0.413), γ gliadins (r = 0.499), total glutenins (r = 0.395), and HMW glutenins (r = 0.389). Oury et al (2006) and Zhao et al (2009) confirmed the negative relationship between Zn content and grain yield.…”
