Fig. 6From: Postharvest chitosan-arginine nanoparticles application ameliorates chilling injury in plum fruit during cold storage by enhancing ROS scavenging system activityEffect of control (no treatment), arginine (Arg), chitosan (CTS) and CTS-Arg nanoparticles (NPs) treatments on total phenols (A), total flavonoids (B), anthocyanins (C), PAL activity (D) and PPO activity (E) in ‘Stanley’ plums during storage at 1 °C for 40 days. Values shown are means ± standard errors (n = 3). Different letters above the bars indicate significant differences at P < 0.05 according to Duncan’s testBack to article page
