*2.9. Statistical Analysis*

Data of the experiment were analyzed statistically using the one-way analysis of variance (ANOVA) with the SPSS 11.0 statistical software [54]. Differences among means were determined using the Duncan test [55]. Data were analyzed using the following model:

$$\mathbf{Y}\_{\rm ij} = \mathbf{U} + \mathbf{A}\_{\rm i} + \mathbf{E}\_{\rm ij} \tag{8}$$

where U is the overall mean, Ai is the effect of wheat germ oil, rocket seed oil, and their mixture treatments; and Eij is the random error.
