Effect of inoculation on essential mineral uptake of Tetraria comosa grown on ultramafic substrate. Relative variations of element content in shoots and roots are expressed as % of element content in dry mass of tissues of inoculated plants compared with controls. Bars represent means, and error bars represent standard deviation of means (n = 3). Different letters above columns indicate significant differences at p < 0.05. The same coefficient to letters refers to one element analysis. The letters and coefficients with an asterisk indicate significant differences with controls at p < 0.05.
