### Minerals in Y. filifera Flowers  
In the analysis of variance (ANOVA), significant differences (\(p<0.01\)) were found between the macro- and microelements, except for the Na and Cu contents, as a function of the origin locations of the samples. For all the minerals evaluated except for Na, there was greater variance (=mean square) due to the effect of the origin location than due to the error effect (Table 1), which was part of the linear model of analysis and sources of variation in the ANOVA. All these results indicate that the greatest cause of the variation was due to the effect of sample origin or location rather than the effect of the interactions of samples and variations within samples or replicates. \begin{table}
