Fig. 5From: Interaction of silicon and manganese in nutritional and physiological aspects of energy cane with high fiber contentLeaf area (a), root dry mass (b) and total dry mass (c) of type II energy cane plants (Saccharum spontaneum L.), cultivated in Mn-sufficient and Mn-deficient nutrient solution in the absence (-Si) and presence (+ Si) of Si. **Significant at 1% probability; *significant at 5% probability, and ns non-significant by the F-test. Different lowercase letters compare Si conditions under the same Mn condition, while different uppercase letters compare Mn conditions under the same Si condition (p < 0.05 by Tukey’s test). Bars represent the standard error of the mean, n = 5Back to article page
