2.4. Statistics
Bioassays were established on basis of a completely randomized
experimental design. The data was analyzed by one-way ANOVA
using STATISTICA 8.0 for Windows (StatSoft„ 2007). Data normality
and variances homogeneity were respectively evaluated with
Kolmogorov–Smirnoff and Levene tests. Tukey’s test was used to
determine differences between means at P < 0.05.
