Figure 1From: Exogenous hydrogen peroxide increases dry matter production, mineral content and level of osmotic solutes in young maize leaves and alleviates deleterious effects of copper stressThe effect of H 2 O 2 application on Cu concentration under excess copper in maize cultivars. The plants were submitted to four treatments: control (C); H2O2 treatment (H2O2); Cu stressed (Cu); Cu stressed plus H2O2 pretreatment (Cu + H2O2). Vertical bars represent standard deviation. Different letters denote significant differences between the two cultivars along with different treatments at p < 0.05.Back to article page
