*2.3. Statistical Analysis*

The two-way analysis of variance (ANOVA) method was used to evaluate the data for the effects of the treatments on the investigated parameters. According to Snedecor and Cochran [36], the treatment means were separated and compared using the least significant differences (L.S.D.) at the 0.05 level of significance. SPSS 18.0 software was used for all statistical analyses (SPSS Inc., Chicago, IL, USA). In the figures, data were presented as means of standard errors (SE).
