Sodium (mg g⁻¹), potassium (mg g⁻¹), phosphate (mg g⁻¹), hydrogen (mg g⁻¹), aluminium (mg kg⁻¹) and copper (mg kg⁻¹) contents in leaves of thale cress following 1 week exposure to artemisinin at 0, 40, 80, 160 μM concentrations in leaves of <i>Arabidopsis thaliana</i>.

Means followed by different letters are significantly different at p < 0.005. Kolmogorov—Smirnov testing for non-normality and Levene’s testing for heteroscedasticity. Statistical significance of differences among group means was estimated by analysis of variance followed by Duncan test for homoscedastic data and by the Dunnett test for heteroscedastic data. Each value represents the mean (± S.E.) of four replicates. Sodium (mg g−1), potassium (mg g−1), phosphate (mg g−1), hydrogen (mg g−1), aluminium (mg kg−1) and copper (mg kg−1) contents in leaves of thale cress following 1 week exposure to artemisinin at 0, 40, 80, 160 μM concentrations in leaves of Arabidopsis thaliana.
