Figure 8From: 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 inorganic ions under excess copper in maize cultivars. A: Sodium content, B: Potassium content, C: Calcium content, D: Magnesium content. 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
