*2.11. Statistical Analysis*

A two-way analysis of variance (ANOVA) was performed with SPSS software version 17.0 for Windows to analyze the data and presented as a treatment mean ± SE (*n* = 4). The least significant difference (LSD) was calculated for the significant data at *p* < 0.05. The data bars with the same letter were not significantly different by the LSD test at *p* < 0.05. The principal component analysis (PCA) and Pearson correlation analyses (*p* < 0.05, *p* < 0.01 and *p* < 0.001) were carried out using OriginPro software. To create biplots, the first two components (PC1 and PC2) showing the maximum variance in the datasets were considered.
