*2.7. Statistical Analyses*

Comparative analysis of roughness for the natural leaves was performed by the Student's *t*-test for independent variables (results from *S. molesta* were excluded). Hydrophobicity results were compared using the Kruskal-Wallis H test and post-hoc analysis with the Mann Whitney U test and Bonferroni correction. Comparison of hydrophobicity and bacterial adhesion among transferred plates was performed by the one-factor Anova test and multiple comparisons through the Tukey's HSD test. Roughness results among transferred plates were compared using the Kruskal-Wallis H test and post-hoc analysis with the Mann Whitney U test and Bonferroni correction. Bivariate analysis tests were performed after previous verification of compliance with the assumptions of normality and homoscedasticity of the variances through the statistics of Shapiro Wilk and Levene, respectively. Values of *p* < 0.05 were considered statistically significant. Software SPSS (V. 25) was used for statistical analyses.
