Different superscript lowercase letters in the same column indicate statistically significant differences between treatments at the same period and at the same dilution. Different superscript capital letters in the same line indicate statistically significant differences between dilutions at the same period and in the same material. Different superscript symbols in the same line indicate statistically significant differences between periods at the same period and in the same material. (Three-way ANOVA, followed by the Tukey’s test; p<0.05).
